反馈表明金钱损失elevates一个明显的负向偏转事件相关电位（ERP），已被称为反馈错误相关的负性，内侧额叶负性，反馈相关的负性，反馈negativityall概念化，表明负ERP组件，是大于损失的收益。在本文中，我回顾了一个程序性的研究路线，表明这种明显的消极实际上反映了一种与奖励相关的积极性（RewP），这种积极性在非奖励之后是不存在或被抑制的。我把RewP放在一个更广泛的奖赏处理和个体对奖赏敏感性差异的法则网络中。此外，我回顾了将RewP减少与抑郁症状增加和抑郁风险联系起来的工作。最后，我讨论了未来的研究方向的RewP。
Feedback indicating monetary loss elicits an apparent negative deflection in the event-related potential (ERP) that has been referred to as the feedback error-related negativity, medial frontal negativity, feedback-related negativity, and feedback negativityall conceptualizations that suggest a negative ERP component that is greater for loss than gain. In the current paper, I review a programmatic line of research indicating that this apparent negativity actually reflects a reward-related positivity (RewP) that is absent or suppressed following nonreward. I situate the RewP within a broader nomological network of reward processing and individual differences in sensitivity to rewards. Further, I review work linking reductions in the RewP to increased depressive symptoms and risk for depression. Finally, I discuss future directions for research on the RewP.
