How positive and negative feedback following real interactions changes subsequent sender ratings

Abstract

Social evaluative feedback informs us about how others perceive us, constantly updates our expectations of what to receive, and simultaneously changes our view of the sender. However, little is known about the neuronal and behavioral responses when receiving incongruent positive or negative social evaluative feedback. This study (N = 40) investigated how receiving feedback from peers after a real-life interaction modulates behavioral responses and Event-Related Potentials (ERPs). Specifically, ERP modulations by feedback being incongruent with the self-view and incongruent with the feedback expectation were examined along the whole processing stream. Feedback was manipulated such that one peer provided overly positive feedback and the other overly negative feedback, with random computer feedback as a control condition. Behaviorally, participants updated their feedback expectations according to the feedback received from the ‘negative’ and ‘positive’ peers and rapidly changed ratings of the sender towards their positive or negative behavior. Concerning ERPs, separate effects of feedback incongruence based on the feedback expectation or self-view were found during the mid-latency processing stages. Subsequently, both types of incongruence increased late ERP amplitudes, which were also increased when participants substantially changed the ratings of the peer senders. This is the first study that combined neuronal and behavioral measures of evaluative feedback processing, emphasizing that incongruent feedback elicits mid-latency modulations and subsequent updating processes associated with increased late amplitudes. In addition, we find rapid behavioral changes in the ratings for the senders based on their feedback behavior.
