Theoretical accounts propose that people update their feedback expectations asymmetrically, with stronger updating after positive than negative feedback and self-relevant than irrelevant feedback. Further, attributions to the senders influence neuronal responses towards social evaluative feedback. In this study, we examined how both attributed self-relevance and acquired sender valence through their feedback behaviour impact learning about and Event-Related Potential (ERP) responses towards the social evaluative feedback. We investigated these questions in an ERP study (N = 40), where participants received either constant positive or negative feedback from senders, either self-relevant or directed to an unknown person. Participants first indicated their feedback expectations and were then exposed to the feedback and the sender's face. Feedback expectations changed according to sender behaviour over time, while surprisingly, expectations changed stronger for negative senders in general and positive self-irrelevant senders. For feedback, increased P1 responses to worse-than-expected feedback were observed, while mid-latency Early Posterior Negativity; Feedback Related Negativity (FRN) and late components Late Positive Potential to feedback were increased by feedback self-relevance. The FRN was additionally affected by sender valence and expectedness. Our findings thereby reveal different facets of behavioural and neuronal effects of attributed sender self-relevance and acquired sender valence.
理论解释认为，人们会以不对称的方式更新他们的反馈预期，在收到积极反馈后比消极反馈后更新更强，且自我相关反馈比非自我相关反馈后更新更强。此外，对反馈发送者的归因会影响对社会评价性反馈的神经元反应。在本研究中，我们考察了归因的自我相关性以及通过反馈行为获得的发送者效价如何影响对社会评价性反馈的学习以及事件相关电位（ERP）反应。我们在一项ERP研究（N = 40）中探究了这些问题，在该研究中，参与者从发送者那里收到持续的积极或消极反馈，这些反馈要么与自我相关，要么针对一个陌生人。参与者首先表明他们的反馈预期，然后接触反馈和发送者的面孔。随着时间推移，反馈预期根据发送者行为而改变，而令人惊讶的是，总体上负面发送者和积极的非自我相关发送者的预期变化更强。对于反馈，观察到对比预期更差的反馈的P1反应增加，而中潜伏期的早期后负波；反馈相关负波（FRN）以及反馈的晚期成分晚期正电位则因反馈的自我相关性而增加。FRN还受到发送者效价和预期性的影响。我们的研究结果由此揭示了归因的发送者自我相关性和获得的发送者效价在行为和神经元效应方面的不同层面。
