事件相关电位研究报告了在错误委托和反馈表明错误或金钱损失之后出现的与错误相关的负面情绪。本研究考察了在赌博任务中，在决策和随后的反馈之前呈现的预测性线索是否会引发与错误相关的消极情绪。参与者被提供了一个提示，表明在即将到来的试验中获得奖励的可能性(0、50和100%)。结果显示，与Win线索相比，事件相关电位在对损失线索的反应中出现负偏转；这种波形与传统的反馈错误相关负波具有相似的潜伏期和形态。
Event-related potential studies have reported error-related negativity following both error commission and feedback indicating errors or monetary loss. The present study examined whether error-related negativities could be elicited by a predictive cue presented prior to both the decision and subsequent feedback in a gambling task. Participants were presented with a cue that indicated the probability of reward on the upcoming trial (0, 50, and 100%). Results showed a negative deflection in the event-related potential in response to loss cues compared with win cues; this waveform shared a similar latency and morphology with the traditional feedback error-related negativity.
