The interaction between amygdala-driven and hippocampus-driven activities is expected to explain why emotion enhances episodic memory recognition. However, overwhelming behavioral evidence regarding the emotion-induced enhancement of immediate and delayed episodic memory recognition has not been obtained in humans. We found that the recognition performance for event memory differs from that for emotional memory. Although event recognition deteriorated equally for episodes that were or were not emotionally salient, emotional recognition remained high for only stimuli related to emotional episodes. Recognition performance pertaining to delayed emotional memory is an accurate predictor of the context of past episodes.
杏仁核驱动活动和海马体驱动活动之间的相互作用预计可以解释为什么情绪会增强情景记忆的识别。然而，在人类中并没有获得压倒性的行为证据表明情绪会增强即时和延迟的情景记忆识别。我们发现，事件记忆的识别性能与情绪记忆的识别性能不同。尽管对于有情绪和无情绪的情节，事件识别的表现都同样恶化，但只有与情绪情节相关的刺激，情绪识别才保持较高水平。关于延迟情绪记忆的识别性能是过去情节背景的准确预测指标。
