反馈相关负波与社会关系认知

反馈相关负波(feedback-related negativity, FRN)是人类进行结果评价时诱发的一个重要的脑电负成分, 出现在反馈刺激后200~300ms间。作为社会认知研究的可视化指标和工具, 它在社会关系认知中有着十分重要的作用。研究从社会关系与反映并表征社会关系的社会规范两方面阐述了反馈相关负波在社会关系认知中的作用。前者着重阐述了反馈相关负波在作为独立个体所扮演的社会角色和人际关系中的作用, 后者主要介绍了反馈相关负波在分配公平和责任规范中的作用。未来研究需进一步联合其他脑电成分(如P300), 采用更严密的实验设计和研究范式来探讨不同人际亲密度个体在责任分摊过程中的认知神经过程及其在独立担责情况下责任绝对额度对其结果评价和社会关系认知的影响。

Feedback-related Negativity and Social Relation Cognition

Feedback-related negativity (FRN) is an important negative potential component related to the outcome evaluation process and peaks approximately 200~300ms after the onset of feedback stimuli. FRN serves as the indicators and tools of social cognition’s visualization, which plays a significant role in social relations cognition. The present study elaborates the role of FRN on social relations of cognition in the perspectives of social relations and social norms, which reflects and characterizes the social relations. The former focuses on describing the functions of FRN on social relationships and social roles playing by independent individuals; the latter mainly introduces the functions of FRN on allocation of fairness and norms of responsibility. Future studies need further investigations to discuss the neurocognitive processes of responsibility sharing conducted by individuals with different interpersonal intimacy levels and the impact of the absolute amount of independent responsibility on outcome evaluation process and social relations’ cognition, by adapting more rigorous experimental designs and research paradigms, combined with other ERP components (e.g. P300).
