摘　　要：目的:考察情绪调整记忆巩固的心理及神经机制。方法:在被试记忆中性词语后分别呈现正、中、负三类不同效价的情绪图片,并在间隔一天后对词语进行再认测试,同时记录其脑电活动。结果:行为结果显示各情绪条件下再认率均显著高于随机猜测水平,而与正负情绪图片配对的词语再认率显著高于与中性图片配对的词语,且正负间无差异;ERP结果显示额叶前部发现明显的新旧效应,且正负情绪条件比中性条件诱发出更大的FN400新旧效应,但正负条件间无差异,与行为结果一致。结论:情绪调整的记忆巩固主要提高了基于熟悉性的再认成绩,与基于回想的再认无关。Objective： To investigate the mental and neural mechanisms of modulation effect of emotion on memory con- solidation. Methods： Subjects were asked to learn positive, neutral and negative emotion arousing pictures to complete a recognition test one day latter. The ERPs was recorded during the recognition task. Results： Behavior result showed that the rates of recognition in three emotion conditions were significantly higher than in the random-guess condition, and that the rates of recognition on paired emotion pictures were higher than those on neutral pictures. ERPs analysis indicated that stronger old/new effect was showed in the frontal areas, and the regonition task in emotion conditions elicited more FN400 old/new effect than that in neutral conditions. Conclusion： Memory consolidation modulated by emotion affects the recogni- tion based on familarity, but not recollection.
