Abstract

Inhibition of Return (IOR) refers to an individual's slowed localization or discrimination performance for targets that appear in previously cued versus uncued location after a relatively long delay after cue (∼300-500 ms). The current study adopted a cue-target paradigm and used behavioral and event-related potential (ERP) measures to investigate whether IOR would be modulated by emotional faces during an emotion recognition task. For reaction time measure, we found IOR effect and the magnitude of IOR effect were comparable for fearful face target and neutral face target. For ERP measures, valid cues were associated with smaller P1 and larger N1 waveform than that for invalid cues. Fearful faces were associated with a larger N170 than neutral faces. The onset latency of the stimulus-locked lateralised readiness potential (LRP) in the valid cue condition was longer than that in the invalid cue condition, while there was no significant difference on the onset latency of the response-locked LRP between the valid cue and invalid cue condition. These results support the notion that, regardless the emotion component of the stimulus, the inhibitory bias of attention to previous visited location before response contributes to the IOR.

摘要

返回抑制(IOR)是指在线索呈现后相对较长的延迟(约300 - 500毫秒)后,个体对出现在先前线索提示位置与未提示位置的目标进行定位或辨别时反应变慢。本研究采用线索 - 目标范式,运用行为学和事件相关电位(ERP)测量方法,探究在情绪识别任务中情绪面孔是否会调节返回抑制。在反应时测量方面,我们发现恐惧面孔目标和中性面孔目标的IOR效应及IOR效应的大小相当。在ERP测量方面,有效线索比无效线索与更小的P1波幅和更大的N1波幅相关。恐惧面孔比中性面孔与更大的N170波幅相关。有效线索条件下刺激锁定的侧化准备电位(LRP)的起始潜伏期比无效线索条件下更长,而有效线索和无效线索条件下反应锁定的LRP起始潜伏期没有显著差异。这些结果支持了这样一种观点,即无论刺激的情绪成分如何,在反应之前对先前访问位置的注意力抑制偏向都有助于产生返回抑制。
