“…Several studies found that feedback-related theta-band activity (3-7 Hz), widely localized over mid-frontal regions ( Hu et al, 2018 ), was associated with outcome expectancy and reward magnitude, signaling unexpected negative outcomes compared to expected positive outcomes in the context of monetary and social decision-making ( Hajihosseini et al, 2012 ; Cristofori et al, 2013 ). However, despite a great deal of research on social relationships and self-other decision-making ( Li et al, 2020b ; Wang et al, 2021 ), there has been little examination of the effect of social relationship on social feedback processing and outcome evaluation in the perspective of advisor.…”

IntroductionAdvice-giving is a double-edged sword in social interaction, which could bring benefits or considerable losses for the advisee. However, whether the social relationship affects the time course of advisor’s brain response to outcome evaluation after the advice-giving remains unclear.MethodsIn the present study, we used event-related potentials (ERPs) to investigate the modulation of social relationships on advisor’s outcome feedback processing after the advice-giving and related neural activities.ResultsThe results showed larger feedback-related negativity (FRN) to a loss than to a gain both when the friends accepted and rejected the advice, whereas this effect only existed when the strangers rejected the advice, but not when they accepted it. In contrast, the P3 results demonstrated the enhanced neural sensitivity when the strangers accepted the advice than rejected it despite leading to a loss, while a larger P3 amplitude was found when the friends accepted the advice than rejected it and brought a gain. The theta oscillation results in the friend group revealed stronger theta power to loss when the advisee accepted the advice than rejected it. However, this effect was absent in the stranger group.DiscussionThese results suggested that outcome evaluation in advice-giving was not only influenced by feedback valence and social reward, but also modulated by social relationships. Our findings contributed to the understanding of the neural mechanisms of advice-giving outcome evaluation in a social context.
