摘要: 基于位置的返回抑制(IOR)是指对先前注意过的位置上靶子反应变慢的现象。探讨听觉障碍被试检测任务IOR的时程和量是否受听觉剥夺的影响。实验1中,听觉障碍被试和听力正常组被试具有相同的IOR时程和量;但在取消中央线索化的实验2中,当SOA为350ms时,听力正常被试没有出现IOR,听觉障碍被试出现了IOR,说明听觉障碍被试的注意脱离快于听力正常被试。听觉障碍被试对外周靶子的反应快于听力正常被试,表明听障人群外周注意资源增强。这些结果表明听觉障碍被试的空间注意更具有效性和策略性。

Abstract: Location-based inhibition of return (IOR) refers to a slowed response to a target appearing at a previously attended location. We investigated whether IOR time course and magnitude of deaf participants in detection tasks was changed after auditory deprivation. In Experiment 1, we observed comparable IOR time course and magnitude in both deaf and matched hearing participants. In contrast, results of Experiment 2 showed that less IOR in matched hearing participants was found when the fixation cue was absent with a 350ms-SOA, indicating that deaf participants disengaged attention faster than matched hearing participants. Deaf participants responded significant faster to the peripheral targets than the hearing participants, suggesting that deaf people possess enhanced peripheral attentive resources compared with matched hearing participants. Those results indicate that spatial attention is more effective and strategic for deaf participants than matched hearing participants.
