The emotional salience of faces has previously been shown to induce memory distortions in recognition memory tasks. This event-related potential (ERP) study used repeated runs of a continuous recognition task with emotional and neutral faces to investigate emotion-induced memory distortions. In the second and third runs, participants made more false alarms to distracters (repeated from previous runs). Emotion did not modulate the amount of errors, but the extent to which recollection was employed to maximise performance as reflected in the putative ERP correlate of recollection; the parietal old-new effect. Targets from all stimulus classes (positive, negative, neutral) were associated with parietal ERP memory effects, but this was also the case for correctly rejected negative distracters. This suggests that recollection was strategically used to correctly reject negative distracters (recall-to-reject). This finding is consistent with the view that facilitated recollection of negative stimuli may be used to decrease the susceptibility to memory errors induced by emotional salience.
先前的研究表明，面部的情绪显著性会在识别记忆任务中引起记忆扭曲。这项事件相关电位（ERP）研究使用带有情绪和中性面孔的连续识别任务的重复运行，来研究情绪引起的记忆扭曲。在第二和第三次运行中，参与者对分心物（来自前几次运行的重复）做出更多的错误警报。情绪并没有调节错误的数量，但在最大限度地提高表现的程度上，情绪确实影响了被认为是回忆的潜在 ERP 相关物的程度；顶叶新旧效应。来自所有刺激类别的目标（正性、负性、中性）都与顶叶 ERP 记忆效应有关，但正确拒绝的负性分心物也是如此。这表明，回忆被策略性地用于正确拒绝负性分心物（回忆-拒绝）。这一发现与以下观点一致，即促进对负性刺激的回忆可能有助于降低情绪显著性引起的记忆错误的易感性。
