【摘要】：自尊是个体对自己总体的情感性评价。自尊有助于促进个体的心理健康,帮助个体应对威胁,具有重要的适应价值。近年来随着社会认知神经科学的兴起,关于自尊的认知神经机制的研究日益增多,主要涉及三个方面:1)自尊与大脑的结构(如海马体积、前扣带回等区域的灰质体积)和功能(静息态下的默认网络活动以及脑区之间的功能联结性)存在一定的关联;2)自尊调节大脑对威胁的反应,与高自尊个体相比,低自尊个体面对威胁时产生更强的防御性反应,自尊通过影响个体面对威胁时的大脑活动帮助个体更好地应对威胁;3)自我评价过程涉及大脑前额叶、眶额叶、扣带回等多个脑区,自尊调节个体在自我评价过程中的大脑活动。总之,自尊作为个体重要的人格特质,与大脑的结构、功能以及活动状态等都具有一定的关系;这些发现在一定程度上揭示了自尊的神经机制,加深了对自尊及其功能的理解。
[Abstract]:Self-esteem is an individual's emotional evaluation of himself as a whole. Self-esteem helps to promote mental health and help individuals cope with threats, which has important adaptive value. In recent years, with the rise of social cognitive neuroscience, there has been an increasing number of studies on cognitive neural mechanisms of self-esteem, mainly in three aspects: 1) self-esteem and brain structure (such as hippocampal volume. There is a certain correlation between gray matter volume in areas such as anterior cingulate gyrus) and function (default network activity in resting state and functional connection between brain regions). Self-esteem regulates brain response to threats, compared with individuals with high self-esteem. Low self-esteem individuals have a stronger defensive response to threats. Self-esteem helps individuals cope better with threats by influencing their brain activity in the face of threats.) Self-evaluation involves the prefrontal lobe, orbital frontal lobe, and the orbital frontal lobe of the brain. In multiple brain regions, such as cingulate gyrus, self-esteem regulates individual brain activity during self-evaluation. In a word, as an important personality trait, self-esteem has a certain relationship with the structure, function and active state of the brain. To some extent, these findings reveal the neural mechanism of self-esteem and deepen the understanding of self-esteem and its function.
