    The Influence of Topic Structure on Emotional Accumulation in Discourse Context
    2014, 37(6): 1282-1290. 
    Abstract ( )   PDF (8511KB) ( )  
    Reading comprehension needs readers to construct a continuous representation of the information in discourse combined with their background knowledge. During this process, readers can make inferences of the protagonist’s emotions, and update their situation model when the emotions in discourse shift. Besides emotional shifted discourses, there are also discourses that consist of emotions in the same valence. Then, whether the emotional arousal of the discourse is raised by increased emotional cues, that is, this emotion is accumulated? And during the integration of emotion and structure of a discourse, how does topic structure influence the process of emotional accumulation is a question of interest. In addition, through the explicit and implicit tasks, the present study also investigates whether the influence of topic structure on emotional accumulation is modulated by experimental tasks. In our two experiments, two factors were manipulated: topic structure (topic-continuation, topic-shift) and the amount of emotional cues in discourse (one emotional cue, two emotional cues). Through the explicit task in experiment 1, participants were instructed to read 48 critical discourses and 72 fillers (each discourse consisted of two sentences) using a sentence-by-sentence self-paced reading procedure, and were asked to choose a number from 1-9 to make judgment of the discourse emotion (1 represented for the most negative, 9 represented for the most positive). Then the rating grade and the rating time were recorded. Also, the reading time of the second sentence was recorded. In experiment 2, through the implicit task, participants were instructed to answer a comprehension question after reading 1/3 of the materials (each discourse consisted of three sentences, in which the first two sentences were the same as experiment 2, and a third sentence which included an emotional word was added). So besides the reading time of the second sentence was recorded, the reading time of the emotional word in the third sentence and the word following it were recorded too. The results from Experiment 1 showed that for the explicit task where subjects were asked to make emotional judgment, topic structure did not significantly affect emotional accumulation, reflected by the higher grade and the shorter reading time of the discourses that included more emotional cues, both in the topic-continuation condition and the topic-shifted condition. However, for the implicit task where subjects were asked to read for comprehension in Experiment 2, topic structure significantly affected emotional accumulation in such way that discourses which included two emotional cues were read faster than discourses which included only one emotional cue in topic-continuation conditions, but not in topic-shifted conditions. This suggested that the process of emotional accumulation was disrupted in the topic-shifted condition. To conclude, through the explicit and implicit emotional processing tasks, the present study conducted two self-paced reading experiments to investigate how topic structure influenced emotional accumulation in discourse context. It was shown that under the implicit task, more emotional cues led to an accumulation in emotion and facilitated the processing of emotion for the topic-continuation conditions. But when the topic shifted, readers built representations of the current emotion under a new structure, and not based on former emotions in context. For further studies, these results provide evidence for a strong effect of discourse structure on emotional processing in discourse context. In addition, the influence of topic structure on emotional accumulation was modulated by the experimental tasks, which should be paid more attention in researches that related to emotional processing.

    Attentional Bias of Emotional Scene Pictures:Evidence from Eye Movements
    2014, 37(6): 1291-1295. 
    Abstract ( )   PDF (4992KB) ( )  
    Compared with neutral stimuli, emotional stimuli usually gains a cognitive processing priority. In studies of investigating the relations between attentional and emotional processing, emotional materials are observed to cause attentional bias which leads to faster and more effective reacts to emotional materials than neutral ones for participants. However, it is still unsolved that how dose the emotional bias happen. Researchers have been trying to investigate this issue but got no consistent conclusions until now, e.g., some of them suggest that emotional bias comes from attention captures, while others insist that emotional bias derives from disengagement of attention. In the current study, we recorded undergraduate students’ eye movements by EyeLink II eye tracker to explore how emotional pictures induce emotional bias. Emotional scene pictures (22 pictures for positive, negative and neutral scenes each) selected from the Chinese Affective Picture System (CAPS) were used as experiment materials. An antisaccade task and Go/No-go tasks were adopted in Experiment 1 & 2 with 12 and 13 participants respectively. In Experiment 1, for antisaccade task, when a picture (positive, negative or neutral) appeared on the left or the right of the central fixation cross, participants were required to ignore the picture and fixate its mirror location (on its opposite side to the central fixation cross) as soon and precise as possible. In Experiment 2, for Go/No-go task, a picture (positive, negative or neutral) appeared at screen center together with a square displayed at its left or right side with blue or yellow color as the condition clue, which means that the Go and No-go conditions were determined according to the color of the square for participants, and the corresponding relationship between the colors and the meanings of the squares was balanced between subjects. In the Go condition, participants were asked to move their eyes to the color square from screen center as soon as possible, while in the No-go condition, participants were required to ignore the color square and staring at the central picture. We collected correct trial latencies and directional error rates for both experiments. The correct trail latency refers to the time interval between the target onset and the start of the first saccade which is made to the correct direction. The directional error rate refers to the percentage of the first saccades which are made to the incorrect direction accounted for the total number of the fist saccades. Repeated measures ANOVAs of emotion type (positive, negative and neutral) and picture position (left and right) were conduced on the above mentioned eye movement measures for Experiment 1 (antisaccade task). The results showed that there was a main effect of emotion type on correct trial latencies, F (2,11) =8.39,p<.05, ?2=.43, post-hoc analyses further suggested that negative pictures got longer saccade latencies than neutral pictures, p<.05. The main effect of emotion type on directional error rates was also significant, F (2,11) =7.68,p<.05, ?2=.41, further post-hoc analyses revealed higher saccade error rates for emotional pictures (positive and negative) than neutral pictures, ps<.05. These results implying that the emotional pictures can capture participants’ attention even though they were asked not to look at them. The interaction between emotion type and picture position on direction error rates was also significant. F (2,11) =12.36,p<.05,?2=.53, Simple effects analysis showed that the directional error rates was higher for positive pictures displayed on the right side than left, p<.05, while the directional error rates showed no difference between negative pictures appeared on the right and left sides. Repeated measures ANOVAs of emotion type (positive, negative and neutral) were conducted for Experiment 2. In the go condition, there was a main effect of emotion type, F (2,11) =4.54,p<.05, ?2=.29, which showed that, compared with neutral pictures, when emotional pictures (positive and negative) were presented in screen center, participants moved their eyes towards the peripheral targets more slowly. In the no-go condition, the participants were less likely to make saccades to the peripheral target squares which were indicated from a main effect of emotion type on directional error rates, F (2,11) = 44.59,p<.05, ?2=.80. The results of Experiment 2 reflects that emotional pictures can hold attention and participants disengage their attention from emotional pictures more difficultly. In conclusion, we found that emotional pictures capture participants’ attention more quickly, and it is more difficult for participants to disengage their attention from emotional pictures compared with neutral stimuli, which indicated that emotional information affects both the capture and the disengagement of attention. In addition, there was a brain lateralization of attentional bias for positive pictures but not for the negative and neutral pictures.

    The modulation of Vebal Labeling on Emotional Experience
    2014, 37(6): 1296-1301. 
    Abstract ( )   PDF (5362KB) ( )  
    With the development of cognitive and emotional neuroscience, more and more researchers relise that there are mutual interactions between cognitive and emotional systems. Using behavioral and neuroimaging methods, lots of researchers have investigated the modulation effects of emotion on cognitive processing, such as perception, attention, memory and language processing etc. However, there are considerately less studies to examine the effects of cognitive processing, especially language processing, on emotional experience. Therefore, the present research aimed to examine the modulation effects of language (verbal labeling) on individual’s emotional experience through the behavioral method. Two experiments were conducted, and both presented emotional pictures (selected from International Affective Picture System) to the participants, who would self-report their experience about the pictures on likert 9-point scale (1 meant extremely negative and 9 meant extremely positive). Along with the emotional pictures, different verbal labels were put below the pictures, and participants were asked to pay attention to both pictures and verbal labels. In a typical trial, a red “+” fixation was presented 500 ms first, after that the target stimulus (picture and label) was presented 4000 ms and then a response cue appeared which means participants need to press a key (1-9) to express their experience. The inter-stimuli interval is 1000 ms. In order to make sure that participants watched the verbal labels, an old/new word recognition task was performed after the picture watching time. In the experiment 1, the modulation effects of verbal labeling on different emotional experience were investigated. Participants watched three types of pictures (negatice, positive and neutral) with two kinds of verbal labels (neutral Chinese verbal label and Korean characters). Results showed that participants reported significantly less negative experience when the negative pictures were paired with a verbal label other than Korean characters, however, no significant differences were found in neutral and positive pictures. These results suggested that verbal labelings have effects on the individual’s experience, and the access to word meaning is necessary to produce this effects since the unknown Korean word label cannot affect the experience. To explore whether the effects of word label are located in deeper semantic processing level, we manipulated the affective meaning of word label in experiment 2. Negative pictures were paired with negative, positive and neutral word label respectly. The results showed that the subjective experience of participants was significantly higher when negative pictures were paired with negative and positive word label other than neutral label. In other words, the affective meaning of word label have remarkable impact on individual’s experience. These results cooperate with our hypothesis that meaning access of word label is essential for labels to take effects. Taken together, we not only investigated the influence of verbal labeling to different types of experience, but also the influence of different verbal labeling to the same experience. Experiment 1 suggested the verbal labeling effects do exist, and verbal labeling could reduce negative emotion experience. Experiment 2 suggested that the labeling effects of different emotional words had significant differences and the positive or negative labelings were more helpful to reduce negative emotional experience. As advocated by Pessoa (2009), both emotion and cognition determine individual’s behavior, and there are intimate interactions between emotional and cognitive systems. The current studies explored the modulation effects of higher cognitive process (language processing) on individual’s affective experience, which produce relatively solid evidence for the relationship of emotional and cognitive system. However, it worth noticed that no significant label effects were found for positive pictures, and it still need further delicate research to explore the modulation mechanism of labelings on subjective experience.

    The Effects of Tolerance of Uncertainty on Risk Preferences and its Context-Dependency
    2014, 37(6): 1302-1307. 
    Abstract ( )   PDF (5660KB) ( )  
    Abstract Tolerance of uncertainty(TU) is defined as individual differences in the tendency to react emotionally, cognitively, or behaviorally to uncertain situations. Though TU has been related to a variety of cognitive and emotional constructs, it is still not clearly for us about the behavioral consequences of TU. The purpose of the thesis is to probe into the influences of TU, gain-loss context, framing effects, probability levels on risk preferences. We first hypothesize that TU significantly influenced the risk preference, participants with high TU are more willing to take risks than participants with low TU. Secondly, we hypothesize that the effect of TU may differ depending on task characteristics. 629 undergraduate were divided into two groups according to their scores from the intolerance of uncertainty scale, as groups with high and low TU levels in accordance with the high-low-27-percent group method. Hence, a total of 351 students were included in the study. The experimental data were collected from the low and high TU group over a period of time varying between one and two months after the screening phase ended. The running a small shop scenarios used in the present research were designed to begin with either a gain or a loss context, and to be followed by outcomes with three levels of probabilities(high, median, low) respectively. Therefore, it was a 2(tolerance of uncertainty: high vs. low)×2(gain-loss context: gain vs. loss)×2(outcome framing: positive vs. negative)×3(probabilities: high vs. median vs. low)mixed design with probabilities as the within-participants variable and the other three as between-participants variables, the dependent variable is their risk preference, which they choose in a 6 rank tables according to the ‘‘standard gambling’’ paradigm. Repeated Measurement ANOVA with gender as covariates were performed to analyze the data. The results were as follows: (1) The main effects of TU were significant, subjects who have low scores on IUS were more willing to take risks than subjects who have high scores on IUS. (2) There was significant interaction between TU and gain-loss context on risk preference, subjects who have low scores on IUS were more willing to take risks than subjects who have high scores on IUS in loss-context but not in gain-context. (3) There was also significant interaction between TU and the framing of options on risk preference, subjects who have low scores on IUS were more willing to take risks than subjects who have high scores on IUS under the positive frame, but not under the negative frame; at the same time, the further analysis of simple effects also show that people with high scores on IUS but not with low scores on IUS are affected by the framing effect. (4)There was no significant interaction between TU and the levels of probability. In conclusion, the result suggested that TU can influence risk preferences and the influence is context-dependent, in which factors like gain-loss context and the framing of options play a role.The implications of the study and possible future research were discussed. Key words tolerance of uncertainty, gain-loss context, framing effects, probability levels, risk preferences, individual differences

    Processing Method of Other-race Effect during the Structural Encoding Stage of Face Processing: ERPs Study
    2014, 37(6): 1308-1312. 
    Abstract ( )   PDF (4003KB) ( )  
    In the literature, it is established that people are better at recognizing faces from their own race relative to faces from other races. This phenomenon is called other-race effect. There have been studies to try to explain this phenomenon. The results indicated that same race faces involved more configural/holistic processing than other race faces. But the theoretical explanation of this phenomenon is still controversial. Especially there were few studies in this field in our country. This study aimed to investigate the neural mechanism underlying the other-race effect, in particular at what stage of face processing differences between same-race and other-race stimuli occur. Event-related potentials (ERP) technique and a race categorization task were used to explore the neural mechanism of face processing. The participants in the research were undergraduate students. Each participant took part in test individually. The materials consisted photographs of Caucasian, African, Asian faces (10 per race and half women). The faces were presented in a frontal view with a neutral expression without distinctive features. The participants were asked to identify as fast and correctly as possible whether face stimuli belonged to their own race or not by pressing with one of two computer keys, during which ERPs were recorded. At the start of each trial, a fixation point appeared at the center of the screen for 300 ms, followed by a face stimulus lasting 900 ms. The offset of each stimulus was followed by a blank-screen during a random inter-stimulus interval (ISI) ranging from 1000 to 1600 ms (mean ISI: 1300 ms). Each of the three ethnic groups was presented in upright and inverted orientations. It was repeated 4 times in one orientation. Thus, a total of 480 trials were presented in 6 experimental blocks with self-timed breaks in-between. Each block consisted of 80 trials. They were presented in a pseudo-random order to avoid immediate repetition of the same stimulus. Before a formal experiment, there was a practice. The participants can enter a formal experiment until accuracy rate was reached 80%. The analyses were based on measurements of behavioral data (reaction, accuracy rate) and electrophysiological data (amplitudes of peak activity). The results were analyzed by repeated measures ANOVA. Greenhouse – Geisser corrections were applied with adjusted degrees of freedom. The results show that (1) for the upright orientation, the peak N170 amplitude was lower for Asian than Caucasian (p<.05) faces, and the former lower than African (p<.05) faces. Significant difference was not found between Caucasian and African faces (p>.05). And inversion effects were significant for all racial groups. It suggested that the peak N170 amplitude was lower for the upright orientation than the inverted orientation. Thus, the inverted faces involved more featural processing than the upright faces. What’s more, we indicated that same-race faces involved more configural/holistic processing, and other-race faces contained more featural processing. More importantly, we found that there was no significant difference between Caucasian and African faces, which can prove our hypothesis to some extent. Previous literatures always presented the differences between the amplitude of same-race and other-race faces. However, this study not only presented the differences between the amplitude of same-race and other-race faces, but also presented the differences between the amplitude of other-race faces. (2) There was no significant interaction between race and orientation. This result was different from some literatures. We considered that Chinese subjects were better at configural/holistic processing. Regardless of races and orientations, configural/holistic processing was involved more or less. Thus there was no significant interaction. This study demonstrates that same-race faces involve more configural/holistic processing than other-race faces, and there is a right hemisphere superiority of N170. Also, we find that the results are differences between Chinese subjects and Caucasian subjects.

    Dissociation between Probability Discounting and Temporal Discounting in the Human Brain
    2014, 37(6): 1313-1320. 
    Abstract ( )   PDF (6442KB) ( )  
    Probability discounting and temporal discounting are important phenomena in people’s daily economic decision making. Probability discounting occurs when people make a choice between different risky options. People tend to have a preference for the safe option in risky decision making. Temporal discounting refers that people tend to discount future benefits when facing decisions involving a smaller immediate gain and a larger future one. In recent years, researchers have had a strong interest in the relationship between probability discounting and temporal discounting. One hypothesis is that delayed rewards options might be evaluated as risky choices, leading to people’s preference for the prompter payoff option in inter-temporal choice tasks. This hypothesis has been supported by some behavioral studies. However, several behavioral studies challenge the single-process explanation. These behavioral studies revealed inconsistent conclusions for the hypothesis. The fMRI studies also suggested the dissociation between probability discounting and temporal discounting. However, the fMRI evidences are based on separate studies using different paradigms. We employed event-related potential (ERP) to explore whether probability discounting and temporal discounting reflected the same underlying process. ERP can provide a continuous measure of mental processing, making it possible to get a clear evidence for this question. The present study recorded ERPs while participants performed a modified version of the “Wheel of Fortune” gambling task. In the task, probability factor (Risky vs. Safe) and temporal factor (One Month vs. Today) was permuted to form four conditions: Today & Safe, Today & Risky, Month & Safe, and Month & Risky. The study design yielded four conditions based on the participants’ selections. Previous ERP studies on probability discounting have identified the error-related negativity (ERN) as a key index of probability discounting. While the ERP studies on temporal discounting showed inconsistent ERP components. We would examine whether the ERN effect would also appear in the temporal discounting process. In order to get the accurate conclusion, we also analyzed all the ERP components of the two processes. We then first examined whether the ERN can also be elicited by choices involving delays. We found that the ERN elicited by the Risky choice was more negative than that elicited by the Safe one, whereas ERN for Month choices did not differ from ERN for Today choices. We then found the different distributions of time process and the electrode between the two processes. Specially, probability discounting occurred in time window of -100~50ms on FCz and time window of 100~350ms on Pz, while the temporal discounting occurred in time window of 200~600ms on Pz. In conclusion, the current study showed that the probability discounting effect (Risky vs. Safe) and the temporal discounting effect (Month vs. Today) had different patterns in ERP waveforms. The differences suggested that the two processes may involve different neural mechanisms.

    The Effect of Object Similarity on Spatial Representation: Evidence from Eye Movements
    Hong-Po ZHANG Zhu DENG
    2014, 37(6): 1321-1327. 
    Abstract ( )   PDF (6096KB) ( )  
    Abstract□□The representations of the location and spatial relationship of objects have been capturing extensive attentions and disputations in spatial cognition research. Considerable evidence indicates that people select reference frames for spatial memory flexibly based on qualities such as the shape of the environment, the configuration of elements, and one’s own experience of the space. There were few researches, however, on the effect of similarity information provided by the objects themselves in the scene. In the present study, two experiments were conducted to investigate the role of similarity of objects in the environment on people’s spatial representation. 25 undergraduates (13 females, 12 males) participated in the Experiment 1, among them a female’s data was excluded for disordered eye movements. Another 24 participants (12 females and 12 males) took part in the Experiment 2. All participants were healthy and had normal (or corrected to normal) vision. In each trial, individuals were presented with a symmetrical scene to learn. The viewing perspective defined as the direction of 315° , and the axis of symmetry defined as the direction of 0°. In the learning process, participants' eye movements were tracked with the German SMI iView X Hi-SPeed Eye Tracking System (sampling rate =1250Hz, refresh rate =100Hz). Subsequently, participants used memory to finish triplet recognition task in each experiment. In the task, they were required to judge if the directional relationship in these triplets were the same as the learned scene. The correct response latencies to the targets were analyzed by ANOVA. In the first experiment with no similar objects in the scene, the participants moved their eyes to fixate on the next object more frequently along the directions aligned with the symmetric axis than along the directions aligned with their viewing direction (p=.002) and other direction (p<.001). The partial scene recognition results showed the mean response latency to triplets including the direction of axis of symmetry was significantly shorter than those including the viewing direction (p=.041). In the second experiment with three similar objects in the scene, the participants moved their eyes to fixate on the next object still more frequently along the directions aligned with the symmetric axis than along the directions aligned with their viewing direction (p=.015) and other direction (p<.001). They also moved their eyes to fixate on the next object more frequently among similar objects than no similar ones (p=.001). The interaction between directions and similarity is remarkable (p<.001). Response latency results revealed that there were no differences between triplets including the direction of axis of symmetry and those including the viewing direction. However, the two-way interaction of direction and similar objects included in triplets was significant (p=.002). Further analyses confirmed that triplets with no similar objects including the direction of axis of symmetry was significantly shorter than those including the viewing direction (p=.002), while triplets with similar objects had no such differences (p=.168). Results indicate that when the layout had a symmetric axis that was different from participants’ viewing direction, the sequence of eye fixations on objects during learning and the preferred directions in partial scene recognition were both determined by the direction of the symmetric axis and the similarity of objects. In conclusion, the present study demonstrated that the similarity of objects in symmetrical scenes affects the construction of frame of reference system on people’s spatial representation.

    The Effect of Semantic complexity on late Chinese-English bilinguals’ English Passive sentence processing
    Wang Pei
    2014, 37(6): 1328-1332. 
    Abstract ( )   PDF (4630KB) ( )  
    Taken 32 Chinese university students of intermediate and high proficiency as subjects whose ages ranging from 23 to 25(average age=24.38), and adopted English passive sentences as experimental materials which were divided into two literal translation sentences and free translation sentences according to whether word order of sentences was changed or not in understanding them in Chinese, the study probed into the effect of second language proficiency on passive sentences processing under semantic complexity. The results showed: Reaction time and accuracy rate of subjects of high proficiency were faster and higher than those of intermediate subjects, indicating that proficiency could still predict the degree and level of English passive sentence processing in in the verb semantic complex situations. At this time the correct rate of the semantic violations is higher and it’s reaction time is shorter, than those of syntactic violations. Double violations and semantic violations caused N400 effect significantly; the correct sentence and syntactic violations did not induce negative N400. Behavioral data supported the effect of inter-Language Syntactic Similarity ---reaction time and accuracy rate on of literal sentences was faster and higher than those of free translation sentences, whereas ERP data indicated that N600 effect was larger in literal sentences, a larger P600 effect was observed in free translation sentences. These results second language proficiency could alter the effect of inter-Language Syntactic Similarity on second sentence processing.

    Hemispheric lateralization in the semantic processing of nouns, verbs and verb-noun ambiguous words in Chinese: Evidence from an ERP study
    2014, 37(6): 1333-1340. 
    Abstract ( )   PDF (6227KB) ( )  
    The human brain consists of two anatomically different but functionally complementary hemispheres. The two hemispheres complement each other for most functions, including language. Nouns and verbs are fundamental and important members of word classes, existing in almost all human languages. The investigation on the hemispheric lateralization in the processing of noun and verb will improve the understanding of human brain and language. A number of studies have investigated the hemispheric asymmetry in the processing of nouns and verbs. However, since the results obtained so far were mainly from studies on languages with rich inflectional morphology, it is unclear whether the hemispheric differences in the processing of nouns and verbs are due to semantic-conceptual properties or morpho-syntactic properties associated with the two word classes. It is reasonable to examine the word class effect along the semantic dimension in a language with little or simple inflectional morphology, such as Chinese. Furthermore, the techniques applied in previous researches were low in temporal resolution which might limit the findings. Event-related potentials (ERPs), which are voltage fluctuations that are associated with some physical or mental occurrence, can measure the processing activities taking place in the human brain with millisecond accuracy. The combination of ERP technique with half visual field (VF) technique which was commonly employed in the study of language asymmetry provided important windows into language processing in the two hemispheres. Thus, the current study, by combining ERP and VF techniques, aims to explore the hemispheric lateralization in the semantic processing of Chinese noun, verb and verb-noun ambiguous words in the left hemisphere (LH) and the right hemisphere (RH). The experiment contained five sets of stimuli: disyllabic unambiguous nouns (UN), unambiguous verbs (UV), verb-biased (V-VN), noun-biased (N-VN) verb-noun ambiguous words and non-words. The stimuli of UN and UV were mainly typical members of their respective word class and the stimuli of V-VN and N-VN selected according to results of subjective ratings. There were 80 stimuli for each set of real word stimuli. Word frequency and number of strokes were matched across four sets of real word stimuli. The non-words, numbering 160 in total, were the juxtaposition of two real characters that do not form real words. The disyllabic compounds were vertically arranged in the left visual field (LVF) and right visual field (RVF) to ensure that each character in the compounds was equally distant from the fixation. The experiment task was a lexical decision task. 17 native Chinese speakers were instructed to judge whether the stimulus, presented to the LVF or RVF randomly, was a real word or not as quickly and accurately as possible. Both behavioral and ERP data were collected and were analyzed with repeated measures ANOVAs. The results showed significant ERP differences between different word classes in intervals of 350-500ms (N400) and 500-650ms (LPC). N400 could index semantic difference between nouns, verbs and verb-noun ambiguous words. In the RVF/LH, the amplitude values of N400 were greater for UN and UV than for V-VN and N-VN and no significant difference was found between UN and UV, V-VN and N-VN respectively. In the LVF/RH, UN elicited more negative N400 than UV, V-VN and N-VN. UV elicited more negative N400 than V-VN and N-VN. However, there is still no significant difference between V-VN and N-VN in the LH. Furthermore, previous studies reported that the N400 could be influenced by the variables of semantic feature and concreteness. To further clarify the roles of semantic feature and concreteness in the word processing, the results of N400 elicited by UV and N-VN were further analyzed with respect to words of comparable levels of concreteness. Results showed that there is a significant difference in N400 between UV and N-VN in the RVF/LH but the difference was reduced in the LVF/RH when stimuli had matched concreteness, indicating that the N400 in the RVF/LH was sensitive to semantic feature and LVF/RH was influenced by concreteness. However, this did not mean that the effect of semantic feature was totally absent for the processing in the LVF/RH. This was because that in the LVF/RH, there were significant differences in N400 between UV and V-VN whose concreteness values were equalled. Therefore, the N400 in RVF/LH was mainly effected by semantic features while the N400 in LVF/RH was effected by both semantic features and concreteness. In addition, the LPC is a component that could reflect the confidence in the decision-making process; the higher the confidence, the more positive the LPC. In the lexical decision process, V-VN and N-VN activated more senses than UN and UV, so they would receive more semantic feedback which would lead to higher decision confidence. N-VN contained more senses than V-VN and this would result in higher confidence for N-VN. Thus, V-VN and N-VN should elicit more positive LPC than UN and UV and N-VN should elicit more positive LPC than V-VN. Results showed the predicted LPC effect in the LVF/RH but not in the RVF/LH. This was because that semantic activation was focal and strong in the LH but broader and weaker in the RH (Beeman 1998; Jung-Beeman 2005). In the RVF/LH, since only the dominant sense of each word was activated, there was no difference on LPC. While in the LVF/RH, multiple senses were activated and therefore LPC effect appeared. The results suggested different roles of left and right hemispheres in the word processing. LH mainly processes semantic features and RH processes both the semantic features and concreteness associated with different word classes. Besides, the difference between UN and UV in Chinese mainly lies in concreteness. UN and UV differ from N-VN and V-VN in semantic features, concreteness and the amount of semantic activation, which reflects different neural mechanisms for processing unambiguous and ambiguous words.

    Judging Frame Influence on Location Priming Effect on Temporal Order Perception
    Jin-Ping LIU Tao Suo
    2014, 37(6): 1341-1345. 
    Abstract ( )   PDF (4414KB) ( )  
    The priming effect refers to that when the stimulus onset asynchrony (SOA) between the two stimuli is short (including 0 msec) an observer often reports that the primed stimulus appeared first. Several Previous studies have found repetition priming effect on temporal order perception and this priming effect was due to both enhanced visual processing of the priming stimulus causing it to be perceived as having occurred earlier and a response bias to guess as the “correct” response the more highly activated primed stimulus when the observer has no distinct perception of temporal order. To explore the influence of decisional bias on location priming effect on temporal order perception, the study was conducted using the task of temporal order judgments including two response instructions (which stimulus appearing first and last). The targets of this experiment were composed of pairs of figure stimuli: a square and a diamond. Two visual targets were presented either left or right of center of the screen at short temporal intervals or simultaneously. Prior to their onsets, a red circle as a prime appeared briefly in the same location as one of the stimuli. In one block, 18 undergraduates made temporal order judgments by responding which of two shapes appeared first (TOJ-1ST instruction) and in another block, which appeared second (TOJ-2nd instruction). The experimental results showed that there were significant main effects of instruction and priming as well as a significant interaction of these factors in 84 and 42 ms SOA, and the instruction effects did not reach significance in 0 ms SOA. In conclusion, the data of the present study provided evidence to support the hypothesis that the decisional bias had a significant influence on location priming effect on temporal perception, and the mechanism of priming effect of temporal order perception involved cognitive decisions.

    The Mechanism of Action of Emotion in Decision-Making:A Review of Theoretical Researches
    2014, 37(6): 1346-1353. 
    Abstract ( )   PDF (8191KB) ( )  
    With the continuous development of decision-making psychological research field, decision researchers are paying increasing attention on the role of emotion plays in decision-making process. Based on the development of emotion theory, Cognitive Appraisal theory of emotions, Moral Emotions Theory and Motivational Dimensional Model of Affect bring new views on emotion for decision researchers. Because of the emergence of newly developing emotion perspective, the decision researchers deepened the knowledge of the mechanisms for decision-making. The Affect Infusion Model, Risk Analysis Dual Theory, Emotion as Social Information Model and Neural Affective Decision Theory are developed to describe how emotion plays a role in different types of decision-making. Based on the review of above models, the authors makes some recommendations on future research direction. The first, to strengthen validation researches of related emotion theories in different types of decision-making situations. The second, to make further thinking about mechanism of emotion in different types of decision making at perspectives of embodied emotion. The third, to take more broadly aspects into account the characteristics of emotion and cognition, integrate theoretical system at the perspective of interaction between emotion and cognition. Finally, to pay more attention to the interpretations of the natures of different emotions and their mechanism in decision-making. In addition, both emotional and cognitive regulations have certain universality and complexity, and have huge potential adaptive roles. How to make a better understanding and interpretation of such emotion-cognition regulation relationship in psychological experiments has brought challenges and expectation for future researchers.

    Review of Research on Drivers’ Hazard Perception
    Long SUN CHANG Ruo-Song
    2014, 37(6): 1354-1358. 
    Abstract ( )   PDF (5055KB) ( )  
    Hazard Perception, defined as drivers’ ability to detect the latent hazard and respond to it quickly. Hazard perception is a vital component to safe driving, which differs for one to another. It has been related causally to collision risks and it’s predictable to crash risk. This paper introduces the measurements and applications of hazard perception, aiming at providing some references for future researches. The main measurements used overseas are reaction time method, eye movement method as well as self-assessment method. Based on reaction time technique, Hazard perception test (HPT) is a popular tool used to evaluate drivers’ hazard perception. HPT requires drivers to touch the road users on the screen who are inclined to cause a traffic conflict. Reaction time will be recorded automatically when they touch the screen. At the same time, the location where drivers have touched will be recorded. HPT has been developed in a variety of formats, including those utilizing still images, dynamic video sequences and simulations. HPT is suitable for drivers of all the age and it has been using widely in drivers’ training, assessment and licensure. Using an eye tracker, we can record drivers’ fixation duration, fixation frequency as well as their visual search pattern. Furthermore, these can distinguish the subtle difference of hazard detection between novice and experienced drivers, and provides some basis for hazard perception training program. Also, researchers can split hazard perception reaction time into two parts: from the appearance of hazard to the first fixation, from the first fixation to the final reaction. It enables us to see whether the difference of hazard perception between novice and experienced drivers lies in the phrase of visual processing or cognitive processing. Typically, self-assessment method is always used with reaction time technique together. It requires drivers to rank or classify the hazards emerged in the video clips, or seek the correlations between the rating data and hazard perception reaction time. However, taking its subjective effect into consideration, the rating data, sometimes, can’t reflect the true nature of drivers’ hazard perception. The applications of hazard perception are mainly in the field of how to improve driver’s hazard anticipation ability and their visual search pattern. It’s highlighted that using driving stimulators is an effective tool for training. In the future, we should, firstly, pay more attention to explore the cognitive feature of hazard perception. Then, we should establish a model of its influencing factors so as to predict and analyze traffic accidents better. Finally, we should focus on the commercial applications of its measurements, for instance, developing a standardized HPT or a training intervention program.

    Cognitive Development on the Origins of Species of Children Aged Five to Thirteen
    Li LIU
    2014, 37(6): 1366-1371. 
    Abstract ( )   PDF (5541KB) ( )  
    The origin of species is an important constituent part of science education of scientific biology and children’s intuitive cognition on the origins of species is an essential component of na?ve biology. Previous researches have found that there were four types of explanations endorsed by western children when they considered the origins of species: Evolution, responses indicating that a species was transformed from another species without intentions; Creation, responses indicating that super natural agents such as God created or put a species on earth with intentions; Artificialism, responses indicating that human made or created a species with intentions; Spontaneous-generation, responses indicating natural origins for species which are proximate explanations without intentions (e.g. “emerged from the earth’’). Among the four types of explanations, Evolution and Creation are explanations of ultimate causes and they contradict with each other; Artificialism, posed by Piaget, is a phenomenon that is common among young children; Spontaneous-generation is a proximate explanation that many young children endorsed. Most Chinese children are grown up in a environment with no religious beliefs. Whether or not their intuitive thoughts on the origins of species are different from their western counterparts is a question that worth exploring. The current research used in-depth interviewing method, employing open-ended and closed-ended questions respectively, to explore cognitive development on origins of species (animals and human-beings). Children were from the third year in the kindergarten and first grade, second grade and fourth grade of primary school. The results of open-ended task showed that Chinese children had gone through shifts from mainly spontaneous-generational explanations to mixed spontaneous-genarational and evolutionary explanations and then to mainly evolutionary explanations; evolutionary explanations prevailed over other explanations among the children in fourth grade. What were consistent with what had been found in western cultures were that more evolutionary explanations were endorsed by children with age. The cultural differences were shown in that Chinese children did not echo their western counterparts to be exclusive creationists at about eight to ten years old. In the closed-ended question situation, Chinese children were more inclined to endorse multiple explanations than they were in the open-ended question situation, which was consistent with what had been found in western cultures. The results demonstrated that children’s cognition on the origins of species became more scientific with age. However, their cognitive development was not in the form of replacing one origin cognition with another but in the form of coexistence. The current research results demonstrated that multiple epistemologies coexisted within children’s cognitive system. This was also consistent with what had been found in western children as well as adults. When children are confronted with scientific questions such as the origins of species, they might endorse scientific(such as evolution) as well as supernatural(such as creation) explanations, depending on the situations and their needs. This gives some implications for science education. As long as multiple epistemologies on the origins of species coexist within children’s cognitive system, future studies could focus on what factors influence both children and adults’ endorsement of the multiple epistemologies and how the factors work. The research results reflected cross-cultural consistency as well as diversities between western and Chinese children.

    The Effect of Framing and Confidence on Risky Decision Making in Children from Different Grade
    2014, 37(6): 1372-1376. 
    Abstract ( )   PDF (4433KB) ( )  
    Abstract In our daily life, individuals are likely to make judgments and decisions under uncertain situations. Thus, the individual is faced with the uncertain risk to gain or to lose during the process of making the decisions. Children’s risk decision affects their life and learning, the risk decision made by the children in their experiment situation and the framing effect can well predict children’s risky decisions and behavior in their real life, but the study about this is hard to see in our country. Therefore, the purpose of the study is to discuss the development character of the risk decision under the effect of task framework and confidence on the risky decision made by children from different grade. In the research we used the between-group design of 3 (Grade: grade two/ four/ six)×2 (task framework: gains/ losses)×2 (confidence level: overconfidence/ under confidence), according to the method of random sampling to choose 59 people in grade two as same as in grade four and grade six, We investigated the development characteristics of the risky decision made by 177 children. The participants accomplished five situational experiment tasks alone according to the instructions with the guidance of the experimenters, reported his own confidence level. MANOVA were conducted by SPSS13.0 statistical software to analyse the collected data . Here are the results: (1) Children of different grades show significant difference in conservative decision (F=3.207,p<.05,η2=.036,1-β=.581), risk decision (F=3.034,p<.05,η2=.038,1-β=.606) and preference shift (F=3.122,p<.05,η2=.037,1-β=.594), the further multiple comparisons found that children from grade two have lower score in conservative decision than children from grade six (p<.05), but the situation is just the other way around when it comes to the risk decision (p<.05) and the preference shift (p<.05), however, the difference between grade two and grade four is not significant (p>.05) and so is grade four (p>.05) and grade six (p>.05); (2) Under different task framework, the conservative strategy under benefit framework is far more higher than the loss framework (F=22.422,p<.01,η2=.120,1-β=.997), however, the risk strategy is lower (F=22.911,p<.01,η2=.123,1-β=.997), the score of risk preference shift is obviously lower (F=22.680,p<.01,η2=.121,1-β=.997); (3) Risky decision (F=1.186,p>.05,η2=.007,1-β=.191), conservative decision (F=1.078,p>.05,η2=.007,1-β=.178) and preference shift (F=1.132,p>.05,η2=.007,1-β=.185) made by children with different confidence level is of no significant difference. The interaction of confidence level and grade on children’s conservative decision, risk decision and preference shift is not significant difference, and so as the confidence level and task framework, grade and task framework (p>.05). The main conclusions of the present study are as follows : (1) Children in different grades show different development tendency in risk decision, the younger children of grade two are more likely to take risks than the older children of grade six, grade four is a critical period during the development period of risk decision; (2) The framing effect appears in children’s risk decision shows the phenomenon of preference shift under the gain framework and loss framework; (3) Confidence level show no effect on children’s risk decision.

    Junior Middle School Students' Personality Types and Their Development Characteristics
    Shi-Chao ZHANG
    2014, 37(6): 1377-1384. 
    Abstract ( )   PDF (7230KB) ( )  
    Purposes:The transition to the adolescent is an important stage of children's personality development. When children enter junior middle school and face new developmental tasks, they need to adapt to both physiological and psychological changes, which make this stage an important research topic. Studies on junior middle school students' personality differences can be conducted with two different groups of methods: variable-centered vs. person-centered. The variable-centered methods focus on subjects' factor scores differences. Person-centered methods refer to within subjects' personality types. There are many personalities within subjects, but there are limited typical personality types at the overall level. Person-centered methods provide the profile plot, and include additional information beyond variable-centered methods. They supplement each other. This study is to examine whether the three personality types of adolescents can be replicated in Chinese context. Procedures:Personality development scale for Chinese junior middle school students has proved its reliability and validity by pilot measures, EFA from a sample of 583 subjects, and CFA from a sample of 592 subjects. The Internal consistency reliability, test-retest reliability construction validity and criteria-related validity with NEO-FFI of the scale are ideal as well. Using the Chinese culture as the context, 13-to-15-year-old Chinese children's personality structure is divided into five factors: agreement, intellectual characteristics, conscientiousness, extraversion, and emotional stability, with each including some secondary traits. The structure of the scale is coincided to the Five-Factor Model. Higher factor scores correspond to higher personality development level. In the present study, personality development scale for Chinese junior middle school students is used to measure a sample of 3602 subjects from 14 junior middle schools in the city. And five factors' Cronbach's Alpha coefficients range from .773 to .874. Methods:Latent class analysis and its fit indices such as AIC, BIC,adjusted BIC, entropy, LMR and BLRT output by Mplus are used to identify junior middle school students' personality types. ANOVA and multiple comparisons are used to describe the characteristics of each personality type. Cross-tabulation Chi-square test and multinomial Logistic regression are both used to test and model the development characteristics of personality types using SPSS. Results:According to Robins' theory of self-control and adaptation and the posterior probability of subjects allocation by LCA, junior middle school students' personality can be optimally divided into three types: undercontrolled, overcontrolled and resilient. The resilient personality type is the majority(85.90%),and has the highest scores on all five factors. The overcontrolled personality type has the second highest factor scores on agreement, intellectual characteristics and conscientiousness, moderate extraversion and low emotional stability. The undercontrolled personality type has the lowest scores on most fators. The resilient personality type proportion has a significant trend of decreasing with upgrading while the other two types increase. The resilient personality type proportion of girls is higher than that of boys significantly. The interactive effect between grade and gender on personality types development is not significant. Conclusions:According to the self-control and adaptation theory and based on Five-Factor Model of personality, the rationality of three junior middle school students' personality types are identified under the context of Chinese culture; The resilient personality type is the majority(85.90%) and adaptive, while the undercontrolled(6.7%) and overcontrolled(7.4%) personality types both have high risk of adaptation. There are significant grade and gender effects on personality types.

    The Effect of Stressful Life Events on Adolescents’Tobacco and Alcohol Use:The Chain Mediating Effect of Basic Psychological Needs and Coping Style
    2014, 37(6): 1386-1391. 
    Abstract ( )   PDF (5656KB) ( )  
    Many studies indicate that the ratios of adolescents’ tobacco and alcohol use are rising year by year and adolescents that use tobacco and alcohol use become younger(Chen, Su, Lin, 2012;Ji, 2010;Lin, Fan, Li, Pan, 2010;Ye, Li, Chen, Wang, 2011). Tobacco and alcohol use greatly endangers adolescents’ health. They not only can influence adolescents’ cognitive function and physical function, but also can lead to serious adolescents’ psychological and behavioral problems, such as adolescents crime and suicide(Chen et al., 2012; Kim, Kwak, & Yun, 2010; Ye et al., 2011). Therefore, more attention should be paid to adolescents’ tobacco and alcohol use. It is very necessary to study the potential mechanisms of adolescents’ tobacco and alcohol use so as to design prevention and intervention programs.   Adolescents have to simultaneously face stress from family, school and companion (Niwa et al., 2013; Priess-Groben & Hyde, 2012; Ye, Yang, & Hu, 2012). Stressful life events increase adolescents’ tobacco and alcohol use (Blomeyer et al., 2008; O’Loufhlin, Karp, Koulis, Paradis, DiFranza, 2009; Ye et al., 2011). But a few studies had explored how stressful life events influence adolescents’ tobacco and alcohol use. Mediation addresses how effect is produced. Mediational analysis attempt to identify the intermediary process that leads from the independent variable (e.g. stressful life events) on a dependent variable (e.g. adolescents’ tobacco and alcohol use). We should examine the mediation mechanism of the effect of stressful life events on adolescents’ tobacco and alcohol use so as to prevent and control adolescents’ tobacco and alcohol use.   To examine how stressful life events influence adolescents’ tobacco and alcohol use, 867 adolescents of six schools (430 boys and 437 girls, Mage=14.43±1.05) was recruited in the study to complete self-report questionnaires. The self-report questionnaires used in this study included stressful life events scale, basic psychological needs scale, coping style questionnaire and tobacco and alcohol use questionnaire. The results indicated that: (1) basic psychological needs mediated the effect of stressful life events on adolescents’ tobacco and alcohol use; (2) coping style mediated the effect of basic psychological needs on tobacco and alcohol use. Positive coping style and negative coping style all served to partially mediate the association between basic psychological needs on tobacco and alcohol use. Stressful life events could directly influence adolescents’ tobacco and alcohol use, as well as through influence basic psychological needs and coping style, ultimately influence adolescents’ tobacco and alcohol use. Basic psychological needs and coping style played a chain mediating effect between stressful life events and adolescents’ tobacco and alcohol use. The conclusion of the study had important reference value for prevention and intervention of adolescents’tobacco and alcohol use. Firstly, we should reduce adolescents’stress and train adolescents to better cope with stress. Secondly, we should pay close attention to adolescents’satisfaction of basic psychological needs. Thirdly, adolescents should increase positive coping style and reduce negative coping style.

    The Influence of the number of Combinatorial Elements on Adolescents’ Combinatorial Performances in Sampling Combinatorial Problems
    2014, 37(6): 1392-1396. 
    Abstract ( )   PDF (4459KB) ( )  
    The Influence of the number of Combinatorial Elements on Adolescents’ Combinatorial Performances in Sampling Combinatorial Problems Abstract Purposes The previous studies of sampling combinatorial problems indicate that adolescents at the formal operation stage show different performances in such tasks. We assume that it may be that the increase in the number of combinatorial elements reduces combinatorial performances. The present study examines the possible influence of the number of combinatorial elements on sampling combinatorial reasoning. Methods The present experiment investigated adolescents’ reasoning abilities in sampling combinatorial problems. Participants were 141 tenth graders from a middle school who had not learned the combinatorial knowledge in school instructions. Independent variables were the number of elements in a population and the number of elements in a sample in combinatorial problems. There were three conditions of combinatorial problems: C5,3, C7,3 and C7,4. Three classes’ students were respectively arranged to the three combinatorial problems. For example, a class’ students was arranged to the following C5,3 combinatorial problem. A sports team has five players. They are respectively represented by letter code A, B, C, D and E. Now three members are selected from the five players in the team to constitute a group to participate in a sports team competition project. Q. What are the possible group combinations? Please enumerate all the possible group combinations. Results Results showed that, as the number of elements in a population and the number of elements in a sample increased, participants’ combinatorial performances decreased, and the proportions of participants using the systematic variation method also decreased. The results supported the previous assumption. Conclusions Adolescents’ sampling combinatorial reasoning ability decreases as the number of combinatorial elements increases. It reveals that although the ability of sampling combinatorial reasoning is already acquired by adolescents, it doesn’t reach the level of generalization. It implies that there may be a distinction of a low level and advanced level in its development. Key words: adolescents,sampling combinatorial problems, number of elements, combinatorial strategy

    Relationships Among Interpersonal Attribution, Online communication motives and Cyber-relationship Addiction of College Students
    2014, 37(6): 1397-1403. 
    Abstract ( )   PDF (6667KB) ( )  
    According to the 32th statistical report of CNNIC, the number of internet users in China has reached 546 million and the penetration rate of internet in China has reached 42.1% by the end of june, 2012; and student group is still the mian force of Chinese internet users. With the popularity of Internet, online communication expands the scope of interpersonal interaction by breaking up the constraints of time and space, and it has become a new way of interpersonal interaction gradually. The young internet users under the age of 25 are very active in online communication, and their usage rate in instant messaging, micro-blog, social networking sites and personal space are 86%, 61.6%, 57.7% and 71.9%, which are all higher than that of the whole China’s internet users. Online communication provides a necessarily supplementary way to interact with others, which maintains the relationships in real life, increases social capital and promotes individual’s social adaptation and happiness. But excessive dependence on online communication, namely cyber-relationship addiction, would damage the the relationships in real life, and bring great harm to individual's physical and mental health. The present study was to investigate the impact of inter-personal attribution on cyber-relationship addiction in order to provide empirical evidence and support for cultivating healthy and reasonable online communication activities among college students. And a survey had been conducted to examine the relationship among interpersonal attribution, online communication motives and cyber-relationship addiction of college students, under the framework of Cognitive-behavioral Model, together with the “Use and Gratification” theory and the Psychological Decompensation Hypothesis. The participants were 447 college students; and three questionnaires were used in this study: inter-personal attribution part of MMCS includes 24 items using a 5-point Likert scoring from 0-5, and four subscales, namely ability, effort, luck and scenario, this scale also proposed two attribution tendencies: inner attribution and outer attribution; online communication motives scale includes 15 items using a 5-point Likert scoring from 1-5, and four dimensions, namely seeking friendships, seeking romantic relationship, social compensation and escaping from the reality; the cyber-relationship addiction part of internet addiction scale includes 6 items using a 5-point Likert scoring from 1-5. The results indicated that: (1) The inner and outter tendency of pesonal attribution were both positively correlated with online communication motives, but only outter tendency was positively correlated with cyber-relationship addiction. (2) The effect of the outter tendency of personal attribution on cyber-relationship addiction was partly mediated by online communication motives. The results first indicate that: though people treat internet as a new way of interpersonal interaction, only those with poor interpersonal relationships are proned to immersed in online communication; the “Use and Gratification” theory and the Psychological Decompensation Hypothesis can be embedded in the Cognitive-behavioral Model theoretically to explains the mechanism of non-adaptive cognitive’s impact on internet addiction. At the same time, this result also provides a good inspiration to the prevention and correction of cyber-relationship addiction. Firstly, the attribution, as a cognitive tendency, can be intervened and corrected, so we can prevente and intervene cyber-relationship addiction by correctting the poor interpersonal attribution tendencies; secondly, we can reduce the level of online communication motives and the possibility of cyber-relationship addiction by metting individual’s needs better in real life.

    The Influence of Social Support on Sleep Quality: Evidence from Multiple Mediation Model
    2014, 37(6): 1404-1408. 
    Abstract ( )   PDF (4081KB) ( )  
    In the group of Chinese undergraduate students, the problem of sleep quality was severe. Based on the previous research, social support had protective effect on sleep quality, the more social support individual perceived, and the less sleep quality problem occurred. However, the mechanism of social support’s effect on sleep quality was limited, that few researches explored the mediators between social support and sleep quality. According to Thomsen, Mehlsen, Christensen and Zachariae(2003), pre-sleep negative emotion and cognitive arousal may influence sleep quality directly, and other external variables such as life events had to affect sleep quality through negative emotion or through cognitive activity caused or aggravated by life events. Anxiety and worry respectively as emotional and cognitive variables were popular among college students. Evidence from previous research, which referred to the relationship between social support, anxiety, worry and sleep quality, could support that anxiety and worry were both mediators between the relationship of social support and sleep quality. Multiple mediation model were the mediation model containing two mediators or more, contained three type of parallel multiple mediation model, chain multiple mediation model and composited multiple mediation model. And the present study explored that whether composed multiple mediation model of anxiety and worry could explain the relationship of social support and sleep quality. The present study selected 360 undergraduate students (male 103, female 257) and adopted Pittsburgh sleep quality index scale, perceived social support scale, worry domains questionnaire and state anxiety inventory. Pearson correlation and SEM were used. The results were that common method biases could be accepted in this study; and that the correlation among perceived social support, worry, anxiety and sleep quality were all significant; that in the composited model Χ2 = 155.82, Χ2/ df = 2.69, TLI = 0.94, CFI = 0.95, RMSEA = 0.069, SRMR = 0.050, these results indicated that composited model indicated good fit; the mediating effect in composited model could explain 92.25% of the total effect of social support on sleep quality; the mediating effect of worry in the relationship of social support and anxiety was 0.12; the mediating effect of anxiety in the relationship of worry and sleep quality was 0.14. The present study included that composited multiple mediation model of worry and anxiety could explained the relationship of social support and sleep quality appropriately, and that the mediating effect could play at the same time, or in a chain.

    The Relationship of Master Graduate Students' Perceived Stress, State-Ttrait Anxiety and Perfectionism with Sleep Quality
    2014, 37(6): 1409-1414. 
    Abstract ( )   PDF (4622KB) ( )  
    Abstract Nowadays, there is a growing concern over the issue of the sleep quality. Although everybody hopes a good sleep, many people including master graduate students are troubled by the poor sleep quality. Which psychological factors can make obvious impact on the sleep quality? How are effect mechanisms of the psychological factors on the sleep quality? The researches about such problems are still relatively scarce and not deep enough. In order to further clarify the psychological effect factors and their action mechanisms on the sleep quality, this research explores the effect mechanisms from multiple psychological angles including stress response, emotion and personality traits, and establishes their action model to provide scientific basis for improving the master graduate students’sleep quality . A total of 581 master graduate students were recruited from five universities in Harbin by convenient cluster sampling. All participants’perceived stress, state anxiety, trait anxiety, perfectionism and sleep quality were measured with self-reported questionnaires which included Chinese Perceived Stress Scale (CPSS), Pittsburgh Sleep Quality Index (PSQI), Chinese Frost Multidimensional Perfectionism Scale (CFMPS) and State-Trait Anxiety Inventory (STAI). All data were analyzed through structural equation modeling. The results firstly indicated that each two among all variables showed significant correlation. Secondly, perceived stress had significant direct and positive impact on sleep quality, which can explain more than 3/4 of the effect of perceived stress on the sleep quality. Meanwhile it also affected sleep quality through the state anxiety indirectly. Thirdly, trait anxiety had no direct significant impact on sleep quality, it affected sleep quality through the perceived stress and state anxiety indirectly, and the pathway involving the perceived stress was more important which can explain nearly 2/3 of the effect of trait anxiety on the sleep quality. In addition, maladaptive perfectionism had significant direct impact on sleep quality, and it also can affect sleep quality indirectly through trait anxiety pathway which was the same important as the direct pathway. On the contrary, adaptive perfectionism had no significant direct effect on sleep quality, but it can affected sleep quality indirectly through the trait anxiety, perceived stress and state anxiety. Finally, the total effect of state anxiety, perceived stress, trait anxiety and maladaptive perfectionism on sleep quality quantity was .22, .284, .368 and .468 in turn, which indicated that their effects on sleep quality increased gradually. This study findings clearly show the effect mechanisms of many psychological factors on the master graduate students' sleep quality. Moreover, the findings highlight the more important and fundamental effects of personality traits including perfectionism and trait anxiety than perceived stress and state anxiety on the sleep quality. Therefore, the approches of improving personality traits including perfectionism and trait anxiety should be payed more attention to promote sleep quality. Generally speaking, the study presents possible direction of improving master graduate student' sleep quality. On the one hand, the reduce of the state anxiety and especially the perceived stress can improve sleep quality. On the other hand, the decrease of the maladaptive perfectionism and increase of the adaptive perfectionism can basically reduce trait anxiety, and then lessen perceived stress and state anxiety further, and in the end improve the master graduate students' sleep quality. The main innovation of this study can be summarized as follows. One is the innovation in research objective. This study choosed master graduate students in China as research objective. Their sleep problems are very common, but relevant researches about them have been rare both at home and abroad. The second is the innovation in research contents. Past researches mostly involved the relationship between the two variables. This study explored the effect mechanisms of sleep quality from multiple psychological perspectives. The same research papers as this study have not yet been discovered. The last is the innovation in research results. This study presents a comprehensive action model about the effect of multiple psychological factors on sleep quality.Through the analysis of this model, the effect mechanisms of multiple psychological factors on sleep quality were revealed more deeply and detailed, which make up for the lack of past researches. On the whole, this study deepens and expands the researches about sleep quality, and it provides more clear pathways and strong scientific bases for improving sleep quality from psychological perspective.

    The Relation of Graduate Students’ Fear of Advisors’ Negative Evaluation to Implicit Theories of Master-apprentice Relationship
    Yi LU
    2014, 37(6): 1415-1420. 
    Abstract ( )   PDF (4941KB) ( )  
    Fear of advisors’ negative evaluation is often said “fear of advisors”. Researchers asked graduate students to identify orientations of their face, in which a faculty advisors’ face was presented first. They found that when graduate students saw their advisors’ face, they tended to make slower responses to theirface. Moreover, the more fear of negative evaluations from advisors, the slower responses to their face. In fact, the relation between graduate students and advisors is complex. As a tradition in our culture, teachers are respected like parents, which is to say: “Respect for teachers as a father”. This study was to discuss the phenomenon of fear for advisors, and to analyse the factors from cultural perspective. Before study, we revised the questionnaire of fear of advisors’ negative evaluation which was revised from brief fear of negative evaluation scale. For studying implicit theories about students and teachers, we looked up books about proverbs and motto, and developed implicit theories of master-apprentice relationship scale. After investigating graduate students, we found that the phenomenon of fear of advisors was existent. Compared with female advisors, graduate students were more likely to be afraid of male advisors. And we also found that advisors’ academic titles could influence graduate students’ degree of fear, which was when their advisors were professors, they were more worried. Implicit theories of master-apprentice relationship were related to fear of advisors’ negative evaluation. The deeper idea of consulting teachers, the more afraid of negative evaluation they felt. For studying the relationship of “consulting teachers” and fear of advisors’ negative evaluation, the conception of “consulting teachers” was primed by demonstrating the idea of teachers instructing. The result showed that priming the conception of “consulting teachers”, graduate students would be more afraid of advisors. Graduate students’ fear might be a disadvantage to themselves and their advisors. Because of the fear, students would be focusing on pleasing the advisors rather than playing attention to their study. At the same time, it would reduce communication with their advisors, which would be helpless to their studies and researches. However, graduate students could make great efforts to avoid negative evaluation from their advisors. Maybe we could draw some inspiration about the relationship of graduate students and advisors from these results.

    Older Adults’ Attachment Affects Life Satisfaction: The Mediating Role of Loneliness
    2014, 37(6): 1421-1425. 
    Abstract ( )   PDF (4799KB) ( )  
    Based on the previous research, the society is paying more attention to problems about aging. We should focus on the quality of life and mental health of old people, which is worthy of studying. The life satisfaction is one of the most important psychological indexes which can show the quality of life. Some studies have confirmed that loneliness could predict the life satisfaction. The old people will be faced with a series of loss in the later period of life. The important intimate relationship could provide support and protection as safe guard (Antonucci, Akiyama, & Takahashi, 2004). The attachment could reduce loneliness, thus improving life satisfaction. In the study, the relationship among loneliness, the attachment and life satisfaction was the starting point. We can explore the relationship among them. On one hand, we can understand the states of loneliness and life satisfaction among old people, on the other hand we could provid theoretical support for higher life satisfaction of old people by ascertaining the relationship of the three variables. On the basis of literature analysis, this study used the method of questionnaire investigation. The present study selected 310 old people from six counties of the west of Hubei and Hunan province. The study preliminarily explored the states of attachment, loneliness and life satisfaction about old people. In our study, Emotional versus Social Loneliness Scale(ESLS), Experiences in Close Relationships Inventory(ECR) and Satisfaction with life Scale(SWLS) were adopted to investigate the relationship between older adults’ attachment and life satisfaction. In addition, The control of demography variable to statistical test, such as: Age, sex, residence, living marriage, and education. The results were as follows: 1. The correlation among all the variables were significant: firstly, both the avoidance and anxiety of attachment were positively correlated with loneliness(Zr=0.68, p<0.01; Zr=0.43, p<0.01), and were negatively correlated with life satisfaction(Zr=-0.59, p<0.01; Zr=-0.34, p<0.01), and on the other hand loneliness was negatively correlated with life satisfaction(Zr=-0.70, p<0.01) 2. The nonparametric bias-corrected percentile Bootstrap method was used to analyze the mediating role of loneliness. the avoidance of attachment could negatively predict life satisfaction(p<0.001), the anxiety dimension of attachment also could negatively predict life satisfaction(p<0.001); the avoidance of attachment could positively predict the loneliness ( p<0.001),the anxiety dimension of attachment also could positively predict the loneliness ( p<0.001). To our surprise, the effects that two dimensions of attachment and loneliness predict life satisfaction are different: the avoidance of attachment and loneliness could negatively predict life satisfaction(p<0.001); however, the anxiety dimension of attachment and loneliness could negatively predict life satisfaction( p=0.18,p>0.01). Based on the results of the model test, the conclusion was that the loneliness partially mediated the relationship between the avoidance of attachment and life satisfaction and fully mediated the relationship between the anxiety of attachment and life satisfaction. This study further reveals the importance that loneliness has influence on life satisfaction of old people by examining the mediating variable in a certain extent. In conclusion, we can significantly improve the life satisfaction of old people by reducing their loneliness .

    2014, 37(6): 1426-1431. 
    Abstract ( )   PDF (5545KB) ( )  
    In our daily life, it is very important for everyone to recognize and understand ourselves and other people’s emotions correctly, and to manage and regulate these emotions properly. Thus, emotional competence has great significance for everyone’s development of metal health and physical heath. Children’s emotional competence means that children have emotional knowledge, emotional regulation and expression skills, and the ability to recognize and understand their own and others’ emotions. Children’s emotional competence plays an important role in improving their cognitive abilities, including attention and language competence. Children’s emotional competence can also increase the level of children’s mental and physical health, and improve the ability of children’s social interaction. Furthermore, children’s emotional competence can help children reduce their risk behaviors, such as smoking, alcohol abuse, aggressive behaviors and addictive behaviors. The two programs of Teaching Pyramid and Promoting Alternative Thinking Strategies have the same goals which are in order to improve children’s social-emotional competence and decrease their emotional and behavioral problems. In order to improve children's coping skills under stressful situations, the researchers developed a Fun Friends Project. In this project, children, families, teachers and schools are all involved in the process of intervention. In China, Kou Yu et al. (2006) developed a comprehensive intervention project to enhance children’s emotional competence. In addition, the Ministry of Education and China Association for Science and technology developed the science education experiment ‘Learning by Doing’ which also contributed the development of children’s emotional competence. Therefore, from the perspectives of improving the outside environment and increasing their abilities, these projects effectively decreased children’s emotional and behavioral problems, improved their abilities of emotional recognition, emotional management and emotional regulation. Currently, the topic of children’s emotional competence had drawn great attentions by some researchers. However, there are still many issues to be explored further in this field. Researches in the future are suggested to explore the influencing factors and mechanism of children’s emotional competence, prepare special questionnaires and perfect its interventions. In a word, emotional competence is an issue of individual life-span development, and it is very important for children’s growth and development, in the future, the majority of researchers should continue to explore and study children’s emotional competence more deeply.

    The modulation social identification and social identity importance for the group reference effect
    2014, 37(6): 1438-1443. 
    Abstract ( )   PDF (5309KB) ( )  
    A substantial body of research on the group-reference effect (GRE) has shown that the reliable memory advantage for information encoded about one’s own group over material encoded about other groups. Although the group-reference effect has been confirmed in numerous studies, many issues still remain to be resolved. Among these issues, the most apparent one is what factors may affect the strength of the group-reference effect. Although some external factors affect GRE have been discussed in the previous studies, however, some other factors especially individual factors still need to be further explored. Therefore, the aim of the current study was to examine the importance of the intra-individual social identities, as well as the social identification of different social identities which effect on GRE. To explore whether these factors affect individual self-memory advantage or not, in the present study, we employ adjectives as materials in the GRE paradigm, there are four group reference conditions (national, ethnic, gender, occupation). 25 healthy students participated in this experiment (15 females and 10 males, with a mean age of 23.7 years). This experiment consists of three parts: the encoding phase, distraction phase, recognition phase. During the encoding phase, participants were given a list of personality traits. From that list, asked them to decide whether a given word described themselves. Under the ingroup-reference condition ‘Does this word generally describe Chinese?’ or ‘Does this word generally describe boy/girl?’ and so on. The questions for the outgroup-reference condition are ‘Does this word generally describe American?’ or ‘Does this word generally describe middle school students?’ and so on. The lists of words had been matched for valence, word frequency and length. There were 5 blocks, the first block were exercise, the other four blocks contained 30 trials for each reference condition, so there were 120 trials in total. Following the encoding task, participants completed a 5-min distraction task and then moved on to the recognition task. The participant’s task was to judge whether each word had been presented in the encoding phase. The recognition rates data were submitted to a one-way repeated measures analysis of variance (ANOVA) respectively for the importance and social identification of social identities. There were significant main effect of the importance, F (3, 24) = 3.852, p = .017, η2 = .14, the pairwise comparisons showed that recognition rates of adjectives considered for the high important social identity were remembered significantly better than the moderate and low important social identities (ps < .05). There were no significant main effects of the identification, F (3, 24) = 2.647, p = .064, η2 = .10. The results showed that the more important social identity, the larger the corresponding group reference effect, while the level of social identification had no significant effect on the group reference effect. Our findings suggested that in the individual's self, the different social identities that are arranged in order of importance, the more important the closer the core of self - concept, and the importance also affects cognitive processing of collective self - related information.

    Perspective Taking and Empathic Embarrassment: The Role of Empathic Response and Embarrassing Situation
    2014, 37(6): 1444-1449. 
    Abstract ( )   PDF (4460KB) ( )  
    As a typical social pain, empathic embarrassment can promote positive social interaction among people and has a major impact on individuals’ physical and mental health. With further research, psychologists are paying attention to the study of empathic embarrassment (vicarious embarrassment). But they have not clarify its mental mechanism. The present study suppose that empathic response serve to mediate the association between perspective taking and empathic embarrassment, and the mediating effect of empathic response is moderated by embarrassing situation. Four specific embarrassing situations were used to represent the four typical models of embarrassment, which included the self-esteem model, the transgression of others’ expectations model, the dramaturgic model and the unwanted exposure mode. The four embarrassing situations were presented by recording along with noises to induce participants’ perspective taking, empathic response and empathic embarrassment. Every embarrassing situation was recorded into a male version and a female version, and male participants listened to male version of recordings, while female participants listened to female version. This study also used four questionnaires, which consisted of Interpersonal Reaction Index Scale (IRI), Empathic Response Scale, Perspective Taking Checklist, and Emotion Adjective Embarrassment Scale. Participant form the perspective taking (PT) group and the non-perspective taking (non-PT) group should finish the IRI sale before listening to the recordings to ensure their ability of empathy at the corporate level. The procedure of the Experiment were as follows: Before participants finished listening to one recording, they were informed the instruction of PT or non-PT (41 participants were given the instruction of non-PT, and other 117 participants PT, the way by which the instruction of PT was examined that whether it really induced PT or not), and then written other three questionnaires in turn. There is 15s interval between two trials. Data were analyzed by variance analysis, correlation analysis,and mediating effects regression analysis. The results indicated that (1) there weren’t significant differences on the ability to empathize to others between PT group and non-PT group, and main effects of PT, empathic response and empathic embarrassment among four models of embarrassment were significant; (2) there were significant and positive correlations among perspective taking and empathic response, empathic embarrassment in four models of embarrassment. Regression analysis showed: in four models of embarrassment and in presumptive models, the regression coefficient of the dependent variable(empathic embarrassment) on the independent variable(perspective taking) (the self-esteem model:β=0.24, t=2.38, p<0.05; the dramaturgic model: β=0.27, t=2.97, p<0.01; the transgression of others’ expectations model: β=0.25, t=2.75, p<0.01; the unwanted exposure model: β=0.38, t=24.44, p<0.01), the supposed mediator on the independent variable(M1: β=0.22, t=2.14, p<0.05; M2:β=0.19, t=2.04, p<0.05; M3:β=0.30, t=3.37, p<0.001; M4: β=0.46, t=5.54, p<0.001), and the dependent variable on the supposed mediator(M1:β=0.32, t=3.27, p<0.01; M2:β=0.29, t=3.26, p<0.001; M3:β=0.50, t=6.11, p<0.001; M4: β=0.29, t=3.07, p<0.01) were all significant. Meanwhile, when the mediator(empathic response) went into the regression equation, the regression coefficient of the dependent variable on the independent variable were still significant in both the dramaturgic model(β=0.21, t=2.43, p<0.05) and the unwanted exposure model(β=0.25, t=2.68, p<0.01), but not in both the self-esteem model(β=0.17, t=1.77, p>0.05) and the transgression of others’ expectations model(β=0.10, t=1.18, p>0.05). So the mediating effect was significant; and empathic response mediate partially in both the dramaturgic model(mediator effect=0.06, the 20% of total effect) and the unwanted exposure model(mediator effect=0.13, the 35% of total effect), and mediate fully in both the self-esteem model(mediator effect=0.07, the 29% of total effect) and the transgression of others’ expectations model(mediator effect=0.15, the 60% of total effect) the relationship between PT and empathic embarrassment. (3) Mediating effect of empathic response was moderated by embarrassing situation. These findings above confirm the hypothesis of this study and suggests that when individuals in different embarrassing situation, the strategies used to enhance the ability to perceive the feelings of embarrassment of others who are in embarrassing situation is different. In the situation of negative valuation being emphasized (M1 and M3), empathic response and exception of perspective taking must be enhanced in order to enhance the level of empathic embarrassment. However, in the accidental situation (M2 and M4), the greater perspective taking can improve individual’s ability to feel other people’s feelings directly or through empathic response, when others people are in embarrassment without empathic response.

    Effects of Leader-Member Exchange on Family Undermining: A moderated-mediation model
    2014, 37(6): 1450-1454. 
    Abstract ( )   PDF (4171KB) ( )  
    Research about leader-member exchange (LMX) mainly exists in workplace. But it may enhance the life of the worker in family. Based on work-family enrichment theory and contingency theory, we build a model of LMX, access to resources, negative affect and family undermining. We argue that LMX influences employee’s access to resources, which in turn, leads to their family undermining. In addition, informed by the contingency theory, we further propose that employee negative affect moderates the relationship between LMX and employee’s access to resources, such that LMX are more positively related to employee’s access to resources when employee’s negative affect is high rather than low. To test the model, we collected the data from a bank in cheng du of si chuan province. With the assistance of the human resource manager of the firm, a list of randomly selected 300 subordinates and their spouses was prepared. Three waves of data collection occurring with two-week interval were performed in order to reduce common method bias. Ultimately, our sample consisted of 193 matched husbands-wives dyads. Of the 193 employees, 44% were male. The average age was 30.23 years (sd=6.50), and the average tenure in the organization was 7.62 years (sd=6.99). In terms of their education level , 1.04% held middle school degree or below, 17.10% held high school degree, 64.77% held junior college degree, and 17.1% held a bachelor degree or above. Results of hierarchical regression analysis revealed that: (1) leader-member exchange was negatively related to employees’ family undermining;(2) leader-member exchange was positively related to employees’ access to resources; (3) employees’ access to resources was negatively related to employees’ family undermining; (4) employees’ access to resources mediated the relationship between leader-member exchange and employees’ family undermining; (5) negative affect moderated the relationship between leader-member exchange was positively related to employees’ access to resources, such that the positive relationship was stronger when negative affect was high rather than low.

    Ethical Leadership, Instrumentalism Ethical Climate and Employee’s Unethical Behavior: The Moderate Effect of Perceived Insider Status
    2014, 37(6): 1455-1460. 
    Abstract ( )   PDF (4847KB) ( )  
    Contemporary companies are plagued by ethical problems such as stealing, cheating and abuse of resources etc. These employees’ unethical behaviors have been found to bring a huge damage to companies. As such, the interest in employee unethical behaviors should come as no surprise in both research and in the workplace. Employee unethical behavior refers to “either illegal or morally unacceptable actions to the larger community”. Previous studies have recognized that both organizational factors and individual factors can affect employee unethical behaviors, but few of these studies have considered their effects on unethical behaviors jointly. Thus, to better understand the mechanisms underlying employee unethical behavior, this study proposed and tested a moderated mediation model in which ethical leadership (organizational factor) influences employees’ unethical behavior, with ethical climate (organizational factor) as a mediator and perceived insider status (individual factor) as a moderator. 436 survey questionnaires were distributed to the companies located in Zhejiang and Jiangsu Provinces, covering manufacturing, high technology, real estate, etc. In the end, 412 employees returned the questionnaires (response rate was 94.5%). After screening out the problematic cases, the final sample consists of 379 employees. 48.8% were male, 51.2% were female; the mean age was 30.66; the average of organizational tenure was 6.36. The results showed that 1) ethical leadership was negatively related to instrumental organizational ethical climate; 2) instrumental organizational ethical climate partially mediated the relationship between the ethical leadership of organization and the employees’ unethical behavior; 3) the employees’ perceived insider status moderated the relationship between instrumental organization ethical climate and employee’s unethical behavior; 4) the employees’ perceived insider status moderated the mediated relationship through instrumental ethical climate; that is, the higher the perceived insider status shows that the mediated relationship is stronger. By integrating the factors at organizational (i.e., ethical leadership of organization and instrumental organizational ethical climate) and individual levels (i.e., perceived insider status), this study makes two theoretical contributions. First, our results revealed the mediating role of instrumental ethical climate and the moderating role of perceived insider status, answering the questions of how and when ethical leadership of organization has an impact on employees’ unethical behavior within the same study. In addition, our results showed that followers with high perceived insider status are more likely to be influenced by instrumental ethical climate, and they engage in unethical behavior. As such, this finding opens a new window on the issue of unethical behavior by revealing the “seamy side” of employees with high perceived insider status. In terms of practical implications, managers of organizations should engage in ethical leadership behaviors and act as ethical role models in front of their followers. In so doing, managers of organizations are likely to discourage followers’ unethical behavior in their organizations. Further, our findings suggest that organizations should place high value on ethical rules and regulations as well as create an ethical organizational climate, which also contributes to the decrease in the followers’ unethical behavior. Finally, managers of organizations should pay more attention to the employees with high perceived insider status, given that they are more likely to be influenced by instrumental organizational ethical climate.

    A Study of Money Priming on the Customers’ Need for Uniqueness
    2014, 37(6): 1461-1466. 
    Abstract ( )   PDF (5875KB) ( )  
    The individual's behavior can be the money for the ultimate goal. If one gets lots of money, he/she can get everything that he/she wants or needs, and can have more material and non-material objects. Socio-economic studies have shown that economic stress can cause individual depression, poor physical condition or low sense of control, but if one has lots of money will improve the results of control, protect the individual don't live in unfortunate or unforeseen something, therefore, lack of money will make life worse, and have the money will make life better (Vohs et al., 2006, 2008). But in addition to being exchange media and store of value, money can symbolize different forms of resources, such as security, confidence, freedom, power, and social resource, money can only exist as a concept. Money priming will influence the individual's thinking, behaviors, choices and preferences. However, most of these studies focuse on the interpersonal or social behavior, and money priming researches in the consumer area are still relatively scarce. Therefore, the present study takes consumption as research background, money priming allows individuals to become independent, freedom, and will also affect consumption choice, will change individual social distance and affect its need for uniqueness, and the study will use three experiments to test hypotheses. The purpose of the experiment 1 is to study the influence of money priming on the needs of anticonformity, participants are randomly assigned to one of two conditions (money priming vs. control) in a between-subject design. Money priming reference Mogilner & Aaker(2009) method. After money priming, participants are asked to select one keychain which you like best between Allier and Eiliar brand, and inform that the proportion of Allier brand selected in the previous experiments is higher than Ellier brand. The results show that money priming has influenced needs of anticonformity, and more people choose the choice of Ellier brand, and the unique choices are excluded by the impact of emotion, product performance, evaluation of difficulty and income. Experiment 2 tested the moderating role of meaning of money, participants were randomly assigned to one of three conditions (large money group vs. little money group vs. Control group) in a between-subject design. Money priming reference Hansen et al.,(2013) method, and innovative options to reflect the unique needs of individual, the experimental material is two mugs(one is unique shape, another is the ordinary shape). Compare to the little money priming group, large money priming group have more innovative choice(69.44%[50/72], p<0.05), but data analysis shows that there are not differences between the control group and little money priming group ( p> 0.05). Experiment 3 tested the mediating role of social distance. Money priming reference Hansen et al.,(2013) method, and innovative options to reflect the unique needs of individual, the experimental material is two biscuits of different shapes(one is unique shape, another is the ordinary shape). The results show that money priming will stimulate individual social distance, and social distance lead individuals to seek unique products, more innovative options.

    Review of Task Interruption Management: Based on Human-Computer Interaction Research
    Zong-Kui ZHOU
    2014, 37(6): 1467-1472. 
    Abstract ( )   PDF (5406KB) ( )  
    Task interruptions represent a ubiquitous phenomenon in our everyday world: While performing some primary task, a person is interrupted and must engage in a secondary task before resuming the primary task. Successful TIM has become increasingly important for successful performance in the many fields of work. In this paper we try to undertake a systematic review of the current task interruption management (TIM) research in psychology and HCI, so as to further explore the direction and focus of future research. In the first place, TIM has been defined the method of coordinating the main tasks and interrupting task so as to harness the benefits while minimizing the costs. We also present two fundamentally distinct paradigms of TIM that researchers adopt based on their different goals. One paradigm is Interruption impact reduction paradigm which is the current mainstream, the other is Interruption value evaluation paradigm. The former is purposed to reduce negative impacts of interruptions, the latter is for the sake of harnessing the utility of interruptions. In the next place, in order to Understand why interruption will influence people, five related theories are introduced which are memory for goals, prospective memory, long-term working memory, multiple resource theory and IMSM. The first three theories are all based on memory though they emphasize different aspects of memory. They enable detailed predictions about the disruptive properties of interruptions, such as the most appropriate timing of the interruption, the important role of rehearsal and cues. Multiple resource theory primarily concerns with predicting and explaining multi-tasking performance. The basic tenet of MRT is that, when two tasks compete for the same processing resource within any of the task dimensions, performance is likely to be hampered. IMSM is the first thorough model-based treatment of how people deal with interruptions. It provides a useful framework for hypothesizing task, operator, and environmental factors relevant to TIM, for describing the effects of interruptions and behaviors for handling them, and for identifying dependent measures associated with stages of TIM. Although the basic tenet of the five theories just described is different, there are two common: (1) all of them follow the Interruption impact reduction paradigm and hold that interruptions are disruptive to task performance. (2) The importance of environmental cues is emphasized except MRT. Based on the theoretical basis of TIM research, there have been some encouraging efforts to tackle the issue of handling interruptions. These efforts can be categorized into three classes: one that focuses on the users handling such interruptions, the second focuses on optimizing the design of the interrupt itself, and the last focuses on enhancing or modifying aspects of system design in order to reduce or eliminate the interruptions’ disruptive effects. It can be debated which of the five approaches is most valuable. However, We can take a multipronged approach to improving TIM. In the end, we point out that we should also pay more attention to the positive side of interruption, internal interruption and the role of user’s emotional and social factors in the future TIM research.

    Intuition and analysis of moral intuition
    2014, 37(6): 1473-1477. 
    Abstract ( )   PDF (5302KB) ( )  
    Moral intuition is an important concept in recent moral judgment researches. This paper makes a comment on theoretical and empirical researches over the following three topics in recent ten years or so--What is moral intuition? What is the underlying mechanism of moral intuition? Is moral intuition motivated by emotions or rules? Based on extant literature, the authors suggest that there are several conceptual and theoretical problems with above questions. For the first question, some researchers argue that moral intuition is a special social intuition which emphasizes on the key function of emotions. Neural cognitive researches have found that moral intuitions is related to the function of certain brain areas such as cingulate cortex, basal ganglia, lateral prefrontal cortex, the amygdala, and the orbito-frontal cortex, temporo-parietal junction. These brain areas are also associated with processing of re-evaluation of emotional stimuli, motives and intentions. In addition, the authors also analyzed the essential difference between moral intuition and moral heuristic, and argues that they are two different concepts, for that the former emphasizes the rapidity and integrity of processing, while the latter emphasizes the utilization of simple rules that based on small samples in the short-term memory. Therefore, the essential differences between them were ignored when researchers used the two terms equally. For the question 2 above, both of the universal moral grammar framework (UMG)and the moral foundation theory (MFT) take moral intuition as innate and modularized. However, the greatest challenge that the two theories face is that the modularized mechanism and its classification are inconsistent with the findings in contemporary neuroscience. Accordingly, the authors argue that the embody-metaphor framework of morality with emphasis on the evolution, culture and individual experience may be a promising direction of the origin and formation of moral intuition. Finally, for the question 3, this article shows that it is difficult to adjudicate whether moral intuition mainly motives by emotions or by rules. However, the following points are worthy of noting. First, Studies of the classification of intuitions imply that moral intuition may have different subtypes which could be formed by different mechanisms; Second, recent researches suggest that moral intuition is closely associated with the emotional cognition, including emotional recognition and classification, conferring value (not emotion itself) and moral rules(or beliefs).

    Compare the Diagnostic Assessment Classification Accuracy when the Q-Matrix Contains Error
    2014, 37(6): 1478-1484. 
    Abstract ( )   PDF (5638KB) ( )  
    In recent years, cognitive diagnostic assessment is an area of research that has attracted widespread attention. As we all know, one of the important components in cognitive diagnosis is Q-matrix, because Q-matrix reflects the design of the assessment instrument and is the core element that determines the quality of the diagnostic feedback for the instrument. At present, there are some researches about classification accuracy in DINA model with error existed in Q-matrix. These studies indicate that the quality of the Q-matrix has a great influence on the diagnostic accuracy rate, and also indicate that cognitive diagnosis models constructed around Q-matrix are sensitive to the accuracy of Q-matrix, greatly influenced by Q-matrix, and mostly, the starting point of these research are “if the Q-matrix contains errors, how does it affect the accuracy of parameters estimation and classification accuracy”. Up to now, the most problem is that we haven’t an effective method for validating the Q-matrix at hand. Different diagnostic models have different diagnostic classification accuracy rate, and affected by factors that are not the same. Bayesian networks is one of a widespread concerned model, it has strong processing capacity to uncertainly problem. Starting from another perspective view, uses Bayesian network model which less affected by Q-matrix as diagnosis classification model. Compares Bayesian network with the DINA model in cognitive diagnostic classification accuracy on the base of a Q-matrix which contains errors. Bayesian network classification model is less affected by the Q-matrix than DINA model. Then, two simulation studies are carried out. The first is to study the performance of DINA and Bayesian network classification model when the Q-matrix contains error items, the data is generated under DINA model. To be fair, the data generated in the second research doesn’t base on any specified models, adopts the method introduced by Leighton, Gierl & Hunka(2004). Investigates the effect of different type of Q-matrix (contains a reachable matrix or not), contain different type of error (contain 0, 5, 7, 10, 13, 15 items which have 0, 1, 2, 3 erred calibrate attributes) during classification in different models. The performance of Bayesian network classification model was superior in many cases than DINA model. When Q matrix contained a reachable matrix and 5(or less) error specified items, the performance of DINA model was slightly better than the Bayesian network classification model; but when Q matrix didn’t contained a reachable matrix, or contained more than 5 error specified items, the Bayesian network classification model is better than DINA model.

    Estimation of Unknown Parameters in Graded Response Model by Back-Propagation Neural Network
    2014, 37(6): 1485-1490. 
    Abstract ( )   PDF (4940KB) ( )  
    Computerized adaptive testing (CAT) is based on item response theory (IRT) ,which requires a large-scale item bank, and each item in item bank needs item parameters, the item bank of CAT needs to be constantly updated, the item parameters are very important when the bank is constructed and updated. At the present, statistical methods are used for estimating the item parameters, which need to have enough items and examinees, otherwise, it may lack of precision or lead to failure. These limitations are the motivation behind some research to use other adaptive approach to estimate the parameters. Some researchers proposed a novel solution based on back-propagation(BP) neural network to solve the above mentioned limitations. Based on dichotomous model, the parameters were estimated with BP neural network, their study results showed that, for small samples, there are higher precision of the item parameters estimated by neural network than that by statistical methods. Polytomous items can provide more information than dichotomous items, and adopting polytomous items in test is a research direction of CAT. In this paper, the BP neural network and dimension reduction method are adopted to estimate items parameters and examinees ability based on Graded Response Model( GRM) model. First of all, MATLAB toolbox is used to design network, and some factors such as the number of the BP neural network layers, the number of neurons in each layer, and optimal activation function are discussed. In this paper, three layers of the BP neural network is used; each layer neuron number is 4, 12, 1;and s type function ‘Tansig' is used in the first and second layer, the third layer used linear 'purelin' function. Then, Monte Carlo simulation are employed to simulate the response matrixes, and the dimensions of response matrixes are reduced as following: the mean score rate of examinee is used to estimate the examinee’s ability, the passing rate of every grade of each item is used to estimate the difficulty parameters, and the correlation coefficient of score between each item and all items is used to estimate discrimination parameter. The vector of input parameters processed by means of reducing dimensions can improve the speed and the precision of estimation. Monte Carlo simulation results show that: (1) in small sample, whether examinees more than items or examinees less than items (such as the 50 examinees 20 items or the 20 examinees 30 items),which is difficult to work well for statistical estimation method, but the BP neural network method can obtain better results, and the training sample is larger, the precision is higher, the result of parameters estimation can be applied in practice. (2) it can be used to estimate more than 15 levels of polytomous item, which are not applicable for traditional estimation methods. (3)the calculation time is greatly reduced, comparing with traditional methods. By reducing dimensions, the new method decreases the inputs of a neural network from a high dimension to a low dimension ,which accelerates the speed of computation and enhances the precision of estimation.

    Abstract ( )   PDF (4060KB) ( )  
    Working alliance and insight are two key variables in counseling process-outcome research. The relationship between working alliance and therapeutic outcome has been confirmed by many studies. Comparing with it, studies of the relationship between insight and outcome are not that many. Limited research shows that insight could positively influence outcome, including immediate outcome, session outcome, therapeutic outcome and tracing outcome. However, up to now researchers haven’t put these two important variables together to predict outcome. There may be some relationship between working alliance, insight and outcome. In order to investigate the relationship, and the way in which these two variables influence outcome, 94 sessions of 12 complete cases in a university counseling center were studied. Their session recordings were first transcribed. And then 6 observers who were divided into 2 groups evaluated insight in these sessions. Their evaluation tool was Insight Evaluation Manual. It was formed through a qualitative study and a measurement study before. Its reliability and validity has been confirmed through the studies. Transcripts were divided into speaking turns. Observers then judged whether there was insight in each speaking turn according to Insight Evaluation Manual. Clients and counselors completed some questionnaires before or after each session. WAI-SR which measures working alliance, SEQ and one question about session effectiveness with Likert 7-ratings which measure session outcome were filled out after each session by both clients and counselors. OQ were filled out by clients before each session. Data were analyzed through Hierarchical Linear Model 6.0. Results show that working alliance positively influence session outcome, no matter evaluated by clients or counselors, but they cannot predict therapeutic outcome. All of the three facets of working alliance which were evaluated by counselors could positively predict session outcome, and these effects are partially mediated by insight. It probably implies that when the three facts of working alliance are good, counselors are more inclined to use influencing skills, such as interpretation, which could more powerfully facilitate insight’s appearance. Insight is positively related with session effectiveness rated by clients and also positively influence therapeutic outcome. Working alliance doesn’t play a mediating role in the relationship.

    2014, 37(6): 1497-1501. 
    Abstract ( )   PDF (4532KB) ( )  
    Mental illness Stigma remains a serious social issue and significant barrier to mental health service. Previous studies have revealed some automatically-activated aspects of mental illness stigma, including implicit negative cognition, passive emotion and discrimination tendency. However, very little has been done to examine the validity of stimuli words representing mental illness in the measurement of implicit stigma. Researchers have found that the labels and symptoms of illness play some role in stigmatization. However, most of symptoms could be concealed by people with mental illness intentionally; and people might fail to identify or distinguish different mental illness for lacking mental health knowledge. Public are more likely to distinguish person with mental illness by labels, which could be conceptualized into two major categories: relevant labels (RL, such as Mental Problem, Mental Counselling, and Psychiatric Hospitals) and specific labels (SL, such as Anxiety Disorder, Depression Disorder, and Schizophrenia). Both kinds of labels were frequently used to measure implicit stigma toward mental illness in existed studies. The purpose of this study was to examine whether these labels represent mental illness in implicit stigma measures. Two experiments in which participants were required to complete one Single Category Implicit Association Tests (SC-IAT) were designed to examine the validity of RL and SL. In the SC-IAT, the labels of attitude object was “mental illness,” and the stimuli words of “mental illness” were respectively 6 RL and 6 SL which had been evaluated in pilot study. Two tests had the same attribute labels (“negative word” and “positive word,”) in the SC-IAT, and the same stimuli words of attribute (12 typical attitude words toward mental illness evidenced in previous study). The three category labels were shown on either side of the screen at the top (i.e., “mental illness” or “negative words” on the right side, and “positive words” on the left side in one stage), and the stimuli words were presented at the centre of the screen consecutively. The task of SC-IAT requires items to be classified when the category labels are paired on either side of the screen. This paradigm assumed that the stimuli would be classified more quickly if the target and attribute category pairs match participants’ automatic associations, and that the stimuli would be processed more slowly if these pairs contradict automatic associations. Results of SC-IAT showed that stimuli words were classified accurately and more quickly when RL or SL were matched with negative words (attitude words toward mental illness) compared to positive words. These results indicated that both categorical labels had closer automatic association with negative words relative to positive words, and provided some supports to claim that these words were the representative category labels of mental illness and could be used to measure implicit stigma toward mental illness.

    The Relationship between Resilience, Negative Life Events and Depressive Symptoms: Steeling Effect and Sensitizing Effect
    2014, 37(6): 1502-1508. 
    Abstract ( )   PDF (6053KB) ( )  
    Depression is a prevalence psychiatric disorder in individuals exposure to trauma. Resilience and negative life events have been identified as important influence factors of depression. Studies have documented that there are complex interplays among resilience, negative life events and depression. However, few studies systematically explored the interaction relationship between the three variables. Therefore, the purpose of the present study was to explore the interplays among resilience, negative life and depressive symptoms and which circumstances those lead to steeling effect and sensitizing effect. A total of 1573 adolescents following the 2008 Wenchuan earthquake were sampled from Dujiangyan district. At the time of 6, 18 and 24 months after the earthquake, participants were asked to complete questionnaires including the Resilience Scale, Adolescent Self-Rating Life Events Checklist, Depression Self-Rating Scale for Children. 1,041 adolescents were followed up all of the three waves. Data passed the typical analysis. Reciprocal relations were found between negative life events and depressive symptoms. To be specific, Wave 1 negative life events positively predicted Wave 2 depressive symptoms (β=.12), Wave 2 depressive symptoms positively predicted Wave 3 negative life events (β=.12); Wave 1 depressive symptoms positively predicted Wave 2 negative life events (β=.20), Wave 2 negative life events positively predicted Wave 3 depressive symptoms (β=.10). Resilience and depressive symptoms also longitudinal predicted each other across waves. Specifically, Wave 1 resilience predicted Wave 2 depressive symptoms negatively (β=-.09), Wave 2 depressive symptoms negatively predicted Wave 3 resilience (β=-.08). In addition, Wave 2 negative life events negatively predicted Wave 3 resilience (β=-.09), but resilience had no direct effect on negative life events. The results of structural equation model suggested resilience, negative life events and depressive symptoms showed a dynamic interaction relationship. Resilience negatively predicted depressive symptoms (β=-.09), and then depressive symptoms could increase subsequent negative life events (β=.12); negative life events positively predicted depressive symptoms (β=.12), and then depressive symptoms could damage individuals’ resilience (β=-.08); depressive symptoms positively predicted negative life events (β=.20), and then life events could damage individuals’ resilience (β=-.09). In conclusion, resilience, life events and depressive symptoms could influence each other. The patterns of mental recovery presented two different types: steeling effect and sensitizing effect. Those had good mental health and higher level of resilience were more likely to successfully cope with life events and became better and better. In contrast, those had higher psychopathological symptoms and encountered more life events were less likely to keep mental health and high level of resilience. Adolescents had lower level of resilience, higher psychopathological symptoms and encountered higher level of life events should be provided appropriate psychology intervention.

    The psychological study of social class: social cognitive perspective
    2014, 37(6): 1509-1517. 
    Abstract ( )   PDF (8696KB) ( )  
    For more than 100 years, social scientists such as Durkheim, Marx and Engels found that social class has profound impact on social life. However, not until recently, psychologists discovered that the effects of social class on social life can be explained by individual’s cognition, emotion and behavior. In this review, the definition of social class which developed by psychologists was first introduced, then the measure method of objective and subjective social class. Next, it emphasized the impact of social class on individual’s cognition, emotion and behavior from the social cognitive perspective. Social class, a new frontier of psychological inquiry, is a context rooted in both the material substance of social life (income, education, occupation status) and the individual’s construal of her or his class rank. Accordingly, social class can be measured through indices of an individual’s material resources and perceived social class rank relative to others. For the indices of objective social class, most research has focused on level of educational attainment, income, and occupation. In other words, these three measures represent the most widely used indices of an individual’s objective social class. And for the index of subjective social class, the most studies have used is the MacArthur Scale of Subjective Socioeconomic Status. In this measure, individuals subjectively rate themselves in society on a ladder with 10 rungs. The social cognitive theory of social class proposed that through shared experiences, individuals from a particular social class context develop a system of knowledge, action tendencies, and affects that determines how the individual thinks, feels, and relates to others. More specifically, the social contexts of lower-class individuals are characterized by relative resource scarcity, lower rank, uncertainty, and unpredictability, but upper-class contexts are characterized by relatively abundant material resources and elevated rank in society. The life circumstances of lower-class individuals give rise to contextualist social cognitive tendencies and the life circumstances of upper-class individuals create solipsistic social cognitive tendencies. These social cognitive tendencies yield different influences upon upper and lower class individuals’ self, relate to others and perceptions of the social environment. Numerous empirical evidences proved that social class can shape the individual’s basic psychological processes and behavior. Firstly, social class has impact upon self. Large numbers of studies found that contextualist tendencies lead lower class individuals to be more reactive to social threats, more communal, and making more common choice, whereas solipsistic tendencies lead upper-class individuals to be less threat sensitivity, feeling more personal control and making more unique choice. Secondly, Social class can shape individual’s relationship strategies. Lot of research proved that contextualist tendencies lead lower class individuals to be more prosocial, more compassionate, more communal, and paying more attention to group safety and purity, whereas solipsistic tendencies lead upper-class individuals to be more self-focused, more unethical, and paying more attention to individual rights and respect. Thirdly, social class has influence on individuals’ perceptions of the social world. A growing number of empirical evidence suggested that contextualist tendencies elevate empathic accuracy, the tendency of contextual causal explanation, and the level of social constructivist inter-group attitudes among lower-class individuals, whereas solipsistic tendencies elevate upper-class individuals’ trends of dispositional causal explanation, and the level of essentialist inter-group attitudes. However, there are still several limits in the domain of psychological inquiry of social class. First of all, there are likely to be case that subjective social class is a more powerful predictor than objective measures. Future research is needed to better understand why, and in what circumstances, subjective social class is more proximally related to class-based social cognitive patterns. What is more, whether the mobility of social class can influence class-based social cognitive tendencies have never been tested. It is important for future research to consider the impacts of the mobility of social class upon the individuals’ psychological process and behavior. Finally, the most part of the empirical research has been done in the western culture and cultures vary in their social values. It will be important for future research to consider the moderator effects of culture on social class effects. In sum, this article has provided the concept of social class and some of the important measurement methods. Next, the social cognitive theory of social class and empirical evidence in support of this theory has been introduced. Specifically, the material lives of upper- and lower-class individuals differ markedly and translate to class-based differences in social-cognitive tendencies. The life circumstances of lower-class individuals give rise to contextualism social cognitive tendencies, but the social context of upper-class individual creates a solipsistic social cognitive tendency. These class-related social cognitive tendencies yield systematic influences on how people from upper- and lower-class contexts think about the self, relate to others, and perceive the social world. Numerous studies supported this theory that social class can shape the individual’s basic psychological processes and behavior. Finally, the limits of the study of social class and the direction of future research have been discussed.

    Is Virtue a Pre-requisite for Happiness?
    2014, 37(6): 1518-1523. 
    Abstract ( )   PDF (6309KB) ( )  
    Happiness become a hot topic in recent years in the area of psychology. Scholars try to use experimental results in psychology to boost the human happy experiences, guide folks’ life, and influence public policy. But recent research mainly focused on the descriptive and psychological aspect of the conception of happiness, and neglected the normative and evaluative aspect. Virtue is the pre-requisite of happiness from both Confucian and Aristotelian tradition. Aristotle built his happiness theory on his view of virtue. In his theory, to reach the state of happiness, we need to behave in a virtuous way. Confucian tradition also hold a belief that, pure happiness consistent with self-control state which toward ethical norms. Experimental results showed that, behave virtuous can boost happiness. First, religious people were found happier than nonreligious people. This was an indirect evidence because religion always push people to behave in a virtuous way. Religious people were more likely to experience positive emotion, were less inclined to feel anxiety and depression. That might because religious people got more social support, had higher self-esteem and found more meanings in life. Second, people behave more virtuous, they feel happier. This is the direct evidences. People who donated money or spent his own money on others was found happier that who spent money on himself. Prosocial spending make effectively good influence on human emotion and meaning system. This might be an evolved psychological mechanism that we are born to be good. In other research, young kids were happier giving treats away than they were when receiving the same treats themselves. Volunteers also happier than control group in other studies. Writing also can boost human happiness, wrote down his own moral behavior several times per week, the author will be happier. These behavioral effect also found on children participants. Whether doing a moral behavior could improve happiness or not is still an ontology question. Another important question is about the epistemology. That is, how we judge a person who obtain virtues, he is happy or not when compare to other persons who do not obtain virtues. Experimental results showed that, people tend to judge good people happier than bad people. In one condition, behavioral agents was described as a Red Cross field doctor who had both positive and negative mental states. In the other condition, behavioral agent was described as a Nazi death camp doctor who experienced the exact same type of mental states. Comparing the two conditions, participants were significantly more likely to agree with the statement that Richard is happy when he was described as a Red Cross doctor than when he was described as a Nazi doctor. Moreover, when researchers showed a more ambiguous moral situation, like a gay man who, though conflicted because of a religious upbringing, began dating another man, the results were more interesting. When looking at how judgments of immorality and distress predicted judgments of happiness, the judgments of immorality predicted judgments of happiness in a way that was independent of perceived distress. Both judgments of distress and judgments of immorality influenced attributions of happiness, the impact of normative judgments on judgments of happiness was not due to the difference in perceived distress. A series of studies testified this effect. In our belief, we tend to think virtue is the pre-requisite of happiness. Empirical research explained the relationship between virtue and happiness. But the problem of casual attribution of virtue on happiness, and the problem of instrumentality of virtue on happiness still need more research to give a satisfying answer. Because the attribution process is hard to identify in virtue and happiness, which one is the cause and which one is the result. Or if the causation process is a circle, we need more theories and studies to identify the complex mechanisms.

    Researching Self-Face Recognition from the View of Evolutionary Psychology
    2014, 37(6): 1524-1529. 
    Abstract ( )   PDF (6239KB) ( )  
    Face is a unique self-referential stimulus, presumably one’s most distinctive physical feature. A lot of human self-face recognition researches have been done on phylogeny, development, processing advantage and social situation adaptation. According to the surmise of evolutionary psychologists, self-cognition is a set of cognitive processing abilities developed from different evolutionary courses. There are five forms of self, ecological self-knowledge, interpersonal self-knowledge, extended self-knowledge, private self-knowledge and conceptual self-knowledge. They have different evolution and development process. Among them, self-face recognition is an important component. Its development rely on the processing of the extended self-knowledge. We can find its early form in the common ancestors of human beings and chimpanzees and bonobos lived in 6.5 to 4.5 Ma. In the coming evolutionary process, private self-knowledge and conceptual self-knowledge appeared in succession. The whole process recapitulate itself in the mankind's individual development. With the combination of extended self-knowledge, private self-knowledge and conceptual self-knowledge, human beings developed complicated and diversified behavior. It may well be this capacity that distinguishes humans, setting them apart from other animals. At present, though it's just the beginning for studies of neuro-mechanism of self-cognition and self-consciousness, more and more attentions from different researchers were focused in this field. Using self-face as object of study, a lot of works have done on the neurological basis of self-face cognitive processing, allocation of attention, development characteristics, relationship between theory of mind (ToM) with self concept, inhibition mechanism and its relationship with social adaption. Self-face, as the most significant mark for human individual, can be used as unique stimulus in the processing of extended self-knowledge, private self-knowledge and conceptual self-knowledge and also play important role in the exploration of the mechanism of self-processing. Evolution is a very long process and it is also prone to biology. Thus, the theory of evolutionary psychology is an appropriate frame for self cognition processing research, which suggests that the human beings are still in the progress of adaption to the social environment. As the environmental pressure for humans to survival is very little while the human relationships have become more and more complicated, future researches may focus on self awareness and self recognition processing in contemporary social situations, especially in different environment and relationships, which may indicate more and more evidence for the adaptive performance on human behavior.
