脑电位中的反馈相关负波(FRN)通常被观察到用于关于一个人的表现或金钱奖励的结果评估。本研究使用被试猜测第一个刺激(S1)与随后呈现的第二个刺激(S2)的颜色是否相同的任务，证明了作为对猜测的反馈的FRN到S2也对工作记忆中S1和S2的知觉表征之间的冲突敏感。关于一个人表现正确性的反馈的FRN效应被刺激的知觉特性之间的一致性所调制。因此，产生FRN的前扣带回皮质是一个检测反应和知觉冲突的一般冲突监测装置。
The feedback-related negativity (FRN) in brain potentials is typically observed for the outcome evaluation concerning one's performance or monetary reward. Using a task in which the participant guesses whether the first stimulus (S1) would have the same color as the subsequently presented second stimulus (S2), this study demonstrates that the FRN to S2, which serves as feedback to the guessing, is also sensitive to the conflict between perceptual representations of S1 and S2 in working memory. The FRN effect for the feedback concerning the correctness of one's performance is modulated by the congruency between perceptual properties of the stimuli. The anterior cingulate cortex, which generates the FRN, is thus a general conflict-monitoring device detecting both response and perceptual conflicts.
