Inhibition-induced forgetting refers to impaired memory for the stimuli to which responses were inhibited. The present study aimed to examine if it would be modulated by the processing of threatening facial expressions. Angry and neutral faces were presented in a go/no-go task and subsequent memory for faces was measured in a surprise recognition task. In Experiment 1, task-irrelevant angry and neutral faces appeared randomly, and participants responded to the gender of the faces during the go/no-go task. Results showed that the perception of neutral faces was possibly biased by angry faces. So, in Experiment 2, angry and neutral faces were given in separate blocks while participants still responded to the gender. Inhibition-induced forgetting was not modulated by facial expressions, as it was observed for both angry and neutral faces. Finally, in Experiment 3, where participants were assigned to respond to either angry or neutral faces, so that facial expressions were relevant, inhibition-induced forgetting was negated only in the group in whom responses to angry faces were inhibited. The findings suggest that task-relevance plays a key role in the way the processing of emotional information influences the interaction between cognitive control and memory encoding.
抑制诱导遗忘是指对反应受到抑制的刺激的记忆受损。本研究旨在检验它是否会受到对面部表情威胁性处理的调节。在一个“执行/不执行”任务中呈现愤怒和中性的面孔，并在一个意外识别任务中测量随后对面孔的记忆。在实验1中，与任务无关的愤怒和中性面孔随机出现，参与者在“执行/不执行”任务中对面孔的性别做出反应。结果表明，中性面孔的感知可能受到愤怒面孔的影响。因此，在实验2中，愤怒和中性面孔分别呈现，而参与者仍然对面孔的性别做出反应。抑制诱导遗忘不受面部表情的调节，因为在愤怒和中性面孔中都观察到了这种现象。最后，在实验3中，参与者被分配对愤怒或中性面孔做出反应，因此面部表情是相关的，只有在对愤怒面孔的反应受到抑制的组中，抑制诱导遗忘才被消除。研究结果表明，任务相关性在情绪信息处理影响认知控制与记忆编码之间相互作用的方式中起着关键作用。
