自尊的神经机制

在西方心理学中,自尊(self-esteem)被看作是个体对自我整体性的、积极的(而非消极的)感觉,具有特质性和状态性的区分。从一般的自我评价反映出的特质自尊的神经表征主要涉及前额叶的部分区域,状态自尊的神经表征除了涉及这些脑区外,还涉及脑岛等与情绪有关的脑区。了解自尊的本质,解决与自尊有关的临床心理问题及其文化差异争议是自尊神经机制研究的进一步方向。

The Neural Mechanism of Self-Esteem

In Western Psychology,self-esteem is often defined as a positive view of one’s self,with a distinction between trait and state.The trait aspect is usually reflected in people’s general self-evaluation,especially in the laboratory study.The processing of information related self-evaluation is attributed to a series of areas in the medial prefrontal cortex and cingulate cortex,and ventral anterior cingulated cortex responds to valence of information related to oneself.These brain regions are also involved in state self-esteem.Besides,emotion-related brain areas are necessary for neural representation of state self-esteem,such as insula.This review systematically went through the most recent progress in the research field of neural mechanism of self-esteem from the trait-state perspective.However,some important questions remain to be studied in the future.
