自尊是人格的一个方面，它影响对社会地位的看法，并调节社会接受和拒绝的显著性。因此，自尊可能会影响个体对积极和消极社会反馈的神经反应。在功能性磁共振成像扫描期间，参与者（n = 42）参与了一项社会评估任务，在这项任务中，他们表面上从同伴那里得到反馈，表明他们被喜欢或不喜欢。结果表明，低自尊的个体认为自己从他人那里得到的积极反馈较少，并且对积极社会反馈的活动在腹前扣带皮层/内侧前额叶皮层（vACC/mPFC）表现出比消极社会反馈更强的活性。相比之下，高自尊个体的vACC/mPFC活动对积极反馈和消极反馈不敏感，并且这些个体始终高估了从同伴那里得到的积极反馈的数量。体素分析支持这些发现；较低的自尊预示着vACC/mPFC对积极和消极社会反馈的反应呈线性增加。综上所述，本研究结果提出了vACC/mPFC在代表社会反馈的显著性和形成相对社会地位感知方面的功能作用。
Self-esteem is a facet of personality that influences perception of social standing and modulates the salience of social acceptance and rejection. As such, self-esteem may bias neural responses to positive and negative social feedback across individuals. During functional magnetic resonance imaging scanning, participants (n = 42) engaged in a social evaluation task whereby they ostensibly received feedback from peers indicating they were liked or disliked. Results demonstrated that individuals with low self-esteem believed that they received less positive feedback from others and showed enhanced activity to positive versus negative social feedback in the ventral anterior cingulate cortex/medial prefrontal cortex (vACC/mPFC). By contrast, vACC/mPFC activity was insensitive to positive versus negative feedback in individuals with high self-esteem, and these individuals consistently overestimated the amount of positive feedback received from peers. Voxelwise analyses supported these findings; lower self-esteem predicted a linear increase in vACC/mPFC response to positive versus negative social feedback. Taken together, the present findings propose a functional role for the vACC/mPFC in representing the salience of social feedback and shaping perceptions of relative social standing.
