工作记忆中的认知抑制能力在抑郁情绪失调与负性情绪信息加工偏差之间扮演着重要的角色，认知抑制损害使得抑郁者在缓解期内难以摆脱消极信息对认知的影响，从而增加抑郁症复发的危险。.本研究在了解抑郁缓解者一般认知功能的基础上，综合应用认知神经心理学和事件相关电位的方法，从抑郁缓解者控制无关材料进入工作记忆、摒弃工作记忆中的无关材料和操纵工作记忆中的相关材料三个方面去评定抑郁缓解组、抑郁组和对照组在认知抑制能力的差异，系统深入地阐明复发性抑郁缓解者认知抑制损害的机制。.研究从情绪认知心理学、临床精神病学和神经科学交叉领域的角度出发，将认知、抑郁情绪和神经活动间的关系联系起来，从新的视角探讨复发性抑郁个体在缓解期认知抑制损害的机制，扩展了抑郁情绪认知的研究领域。

Cognitive inhibition in working memory(WM)plays an important role between depressive mood disorders and negative emotional information processing biases. Cognitive inhibition impairment makes it difficult for depressive patients to get rid of the impact of negative information on cognition in remission phase, and increases the risk of recurrence of depression..Based on the exploration into the general cognitive function of depressive patients in remission, by applying the method of cognitive neuropsychology and event-related potentials, the study assesses the cognitive inhibition mechanism among the depression remission group, depression group and control group, in terms of the ability to control the access of irrelevant material to (WM) and to discard irrelevant material from WM and to manipulate negative material in WM. The study systematically clarifies the cognitive inhibition damage mechanism in the patients remitted from recurrent depression.From the perspective of inter-discipline area of cognition, depression emotion and neuroscience, the research relates emotional cognition, depression in remission and neural activity, explores the cognitive inhibition damage mechanism of recurrent depressive individuals in remission phase, and expands the research areas of cognition and depression.
