The evaluation of whether an outcome is good or bad is reflected in feedback-related negativity (FRN), which is an event-related brain potential (ERP) component that is elicited by bad events. It is still, however, unclear how the FRN reflects the evaluation of outcomes induced by others. We focused on the relationship between self and other, and recorded ERPs during an alternative gambling task performed by two players (participant and virtual player). FRN was elicited not only by the losses of another in a cooperative situation but also by the gains of another in an antagonistic situation. These results indicate that FRN reflects the evaluation on the basis of one's own evaluative criteria, regardless of the monetary outcome for another.
对结果好坏的评估体现在与反馈相关的负波（FRN）中，这是一种由不良事件引发的事件相关脑电位（ERP）成分。然而，FRN如何反映他人诱导的结果评估仍不清楚。我们关注自我与他人之间的关系，并在两名参与者（一名真实参与者和一名虚拟玩家）进行的替代赌博任务中记录ERP。FRN不仅在合作情境中因他人的损失而引发，也在对抗情境中因他人的收益而引发。这些结果表明，FRN是基于个体自身的评估标准进行评估的，而与他人的金钱结果无关。
