摘要

本研究考察了共同经验效价对社会反馈动态加工的影响。被试在社会反馈期望、社会反馈评价和期望更新三个阶段进行适应性社会判断范式时,记录脑电图。行为分析显示,共享积极体验组的接受期望高于共享消极体验组,拒绝期望低于共享消极体验组;在随后的试验中,接受反馈增加了接受期望。脑电结果显示,在社会反馈期望阶段,SNE条件下拒绝诱发的刺激前负性强度大于接受,而SPE条件下不存在。在社会反馈评价阶段,SNE条件下拒绝反馈诱发的早期额波比接受反馈小,而SPE条件下不显著;在SPE条件下,意外接受诱发的P300大于意外拒绝,而在SNE条件下则没有。在期望更新阶段,在SNE条件下,意外接受诱发的后验θ大于预期接受,而在SPE条件下则没有。这些结果表明,共同的积极经历降低了对即将到来的拒绝的警惕性,增加了对愉悦的敏感性,而共同的消极经历减弱了对拒绝反馈的反应,并从意外的接受中促进了社会学习,从而增强了积极的期望。

Neural responses to shared positive and negative experiences: unveiling the social feedback processing dynamics.

This study examined the impacts of shared experience valence on the dynamic processing of social feedback. Electroencephalography (EEG) was recorded when participants performed an adapted social judgment paradigm with three stages: social feedback expectation, social feedback evaluation, and expectation updating. Behavioral analysis revealed higher acceptance expectation and lower rejection expectation in the shared positive experience (SPE) condition than in the shared negative experience (SNE) condition; receiving acceptance feedback increased acceptance expectation in the subsequent trial. EEG results revealed that at the social feedback expectation stage, rejection evoked a larger stimulus-preceding negativity magnitude than acceptance in the SNE but not SPE condition. At the social feedback evaluation stage, rejection feedback evoked a smaller early frontal theta than acceptance feedback in the SNE but not SPE condition; unexpected acceptance evoked a larger P300 than unexpected rejection in the SPE but not SNE condition. At the expectation updating stage, unexpected acceptance elicited larger late posterior theta than expected acceptance in the SNE but not SPE condition. These results suggest that shared positive experiences reduce vigilance toward impending rejection and increase sensitivity to pleasantness, whereas shared negative experiences blunt reactivity to rejection feedback and foster social learning from unexpected acceptance to enhance positive expectation.

期刊介绍: Cerebral Cortex publishes papers on the development, organization, plasticity, and function of the cerebral cortex, including the hippocampus. Studies with clear relevance to the cerebral cortex, such as the thalamocortical relationship or cortico-subcortical interactions, are also included. The journal is multidisciplinary and covers the large variety of modern neurobiological and neuropsychological techniques, including anatomy, biochemistry, molecular neurobiology, electrophysiology, behavior, artificial intelligence, and theoretical modeling. In addition to research articles, special features such as brief reviews, book reviews, and commentaries are included.
