摘要：SummaryIndividuals 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.Graphical abstractDisplay OmittedHighlights•Self-esteem influences the encoding of self-relevant feedback•Medial prefrontal cortex (mPFC) and posterior cingulate cortex (PCC) served as proxies for semantic and episodic memory encoding, respectively•Semantic processes were most affected by trait self-esteem•Interactions between episodic and semantic processing maintained high self-esteemCognitive neurosciencePsychology
