Individuals constantly encounter feedback from others and process this feedback in various ways to maintain positive situational state self-esteem in relation to semantic-based or trait self-esteem. Individuals may utilize episodic or semantic-driven processes that modulate feedback in two different ways to maintain general self-esteem levels. To date, it is unclear how these processes work while individuals receive social feedback to modulate state self-esteem. Utilizing neural regions associated with semantic self-oriented and basic encoding processes (medial prefrontal cortex (mPFC) and posterior cingulate cortex (PCC), respectively), in addition to time-frequency and Granger causality analyses to assess mPFC and PCC interactions, this study examined how the encoding of social feedback modulated individuals' (N = 45) post-task state self-esteem in relation to their trait self-esteem. Findings highlight the dynamic interplay between mPFC and PCC that modulate state self-esteem in relation to trait self-esteem, to maintain high self-esteem in general in the moment and over time.
个体不断地从他人那里获得反馈，并以各种方式处理这些反馈，以维持与基于语义的或特质自尊相关的积极情境状态自尊。个体可能会利用情节性或语义驱动的过程，以两种不同方式调节反馈，从而维持总体自尊水平。迄今为止，尚不清楚在个体接收社会反馈以调节状态自尊时，这些过程是如何运作的。除了使用时频分析和格兰杰因果分析来评估内侧前额叶皮层（mPFC）和后扣带回皮层（PCC）之间的相互作用外，本研究还利用与语义自我导向和基本编码过程相关的神经区域（分别为内侧前额叶皮层和后扣带回皮层），研究了社会反馈的编码如何调节个体（N = 45）任务后状态自尊与其特质自尊的关系。研究结果突出了内侧前额叶皮层和后扣带回皮层之间的动态相互作用，这种相互作用调节了与特质自尊相关的状态自尊，从而在当下和长期内总体上维持较高的自尊。
