摘要：情绪对记忆的影响是十分重要的，记忆与情绪存在很多的相互作用，主要包括积极和消极两方面。本文从神经机制的角度论述了自传体记忆与情绪的关系，不同情绪状况的自传体记忆的大脑神经机制特征，积极情绪状况下，记忆效果比较好；但消极情绪状态下，记忆效果比较差。其次，自传体记忆是关于个人自己生活事件的记忆；阈下抑郁一般指的是具有抑郁症状,但达不到抑郁诊断标准的个体。阈下抑郁作为一种常见的消极情绪状况对于记忆的影响也是很明显的，尤其是对于自传体记忆的干扰具有明显的情绪一致性效应，既消极情感的视角看待所有的自传体记忆。本文重点分析了阈下抑郁对自传体记忆影响的神经机制，包括脑成像、脑损伤以及临床研究方面的研究现状。最后对相关研究的不足和未来的展望做出了述评。

英文摘要:

ABSTRACT:The influence of emotion on memory is very important. There are some interactions between memory and emotion, mainly including the positive and the negative. This paper discusses the relationship between autobiographical memory and emotion from the aspects of neural mechanisms, the neural mechanisms of brain about autobiographical memory in different emotional situation. At positive mood condition, the memory effect is better; but at a negative emotional state, the memory effect is poor. Secondly, autobiographical memory is about one's own life event; subthreshold depression generally refers to having symptoms of depression, but not up to the standard of the individual diagnosis of depression. As a common negative emotional state subthreshold depression significantly affects memory, especially obviously interferencing autobiographical memory with the emotion congruent effect, also regarding all the autobiographical memory as the negative emotion. At last, this paper reviews the lack and the future prospect of related research.
