Abstract:

This paper we discuss some issues about task interruptions.We try to summarize existing experimental results and theoretical results and analysis what these studies show.Then,we hope that our study can make researchers learn what has done about this area .More importantly,we’d like to further explore the direction and focus of future research.In the first place,based on the literture review of previous task interruptions studies,we present task interruptions’ background and theories.The rapid development of Internet technology weaken space-time boundary of traditional environment.Virtual settings emerges in that the interaction and the sense of immersion in network using expand settings from geographical areas to cyberspace.Human’s behavior setting was divided into real settings and virtual settings.Interaction between these behavior settings generates a new environment system-“R-V” mesosystems(“real-virtual” mesosystems).The intermingling of real and virtual behavior programs within “R-V” mesosystems reflects the polyfunctional nature of settings.In these settings,human-computer interavtion(HCI) is common.

Key words: human-computer interavtion, task interruptions, memory-for-goals theory, threaded cognition theory

摘要:

任务中断是“R-V”居间系统(“现实-虚拟”居间系统)中的人机互动所要频繁面临和处理的一种现象。任务中断对主任务执行的影响主要有三种情况:消极的、积极的和因情况而异的。对中断延迟期间心理作用机制的研究揭示了中断延迟期间的准备是如何对主任务恢复发生作用的,主要理论包括:任务转换理论,长时工作记忆理论,目标记忆理论和线程认知理论。任务转换理论为中断延迟作用机制的研究提供了基础的模式,目标记忆理论和长时工作记忆理论各自提出了复述和编码两种不同的观点,线程认知理论主张多线程并行,深化了任务中断的研究。未来的研究应关注于研究中断对主任务执行产生不同影响的原因、影响中断任务执行期间复述机会的因素以及中断延迟期间的准备是对信息的复述还是编码。对任务中断理论的综述意义在于使未来有关任务中断的研究更加深入且具有实践意义。
