以往的研究结果评价和性能监测使用赌博或简单的认知任务已经确定了两个事件相关电位（ERP）的组成部分，特别是相关的神经反应的决策结果。反馈相关负波（FRN）通常发生在反馈刺激开始后200 - 300 ms，主要编码结果的效价，而P300是200 - 600 ms之间的最正峰，与结果评价的各个方面有关。本研究调查了涉及感知复杂反馈刺激（即，女性面孔）类似于由简单反馈引起的那些。我们要求参与者判断模糊面孔的吸引力，然后向他们展示未模糊的面孔作为内隐反馈。FRN效应可以在ERP波形中识别，尽管在延迟的300 - 380 ms时间窗口中，与初始判断不一致的面孔比与判断一致的面孔引起更多的负向反应。然而，ERP波形没有显示典型的P300反应模式。通过主成分分析（PCA），P300效应呈现出明显的模式：与初始判断一致的面孔比与初始判断不一致的面孔P300更积极，有吸引力的面孔比无吸引力的面孔P300更积极。反馈一致性的影响没有相互作用的影响，吸引力的FRN或P300组件。这些研究结果表明，参与处理复杂的反馈刺激与社会层面的大脑反应一般类似于参与处理简单的反馈刺激在赌博或认知任务，虽然需要适当的数据分析手段来揭示典型的ERP效应，可能已被复杂的认知（和情感）过程复杂的刺激。
Previous studies on outcome evaluation and performance monitoring using gambling or simple cognitive tasks have identified two event-related potential (ERP) components that are particularly relevant to the neural responses to decision outcome. The feedback-related negativity (FRN), typically occurring 200–300 ms post-onset of feedback stimuli, encodes mainly the valence of outcome while the P300, which is the most positive peak between 200–600 ms, is related to various aspects of outcome evaluation. This study investigated the extent to which neural correlates of outcome evaluation involving perceptually complex feedback stimuli (i.e., female faces) are similar to those elicited by simple feedback. We asked participants to judge the attractiveness of blurred faces and then showed them unblurred faces as implicit feedback. The FRN effect can be identified in the ERP waveforms, albeit in a delayed 300–380 ms time window, with faces inconsistent with the initial judgment eliciting more negative-going responses than faces consistent with the judgment. However, the ERP waveforms did not show the typical pattern of P300 responses. With the principal component analysis (PCA), a clear pattern of P300 effects were revealed, with the P300 being more positive to faces consistent with the initial judgment than to faces inconsistent with the judgment, and more positive to attractive faces than to unattractive ones. The effect of feedback consistency did not interact with the effect of attractiveness in either the FRN or P300 component. These findings suggest that brain responses involved in processing complex feedback stimuli with a social dimension are generally similar to those involved in processing simple feedback stimuli in gambling or cognitive tasks, although appropriate means of data analysis are needed to reveal the typical ERP effects that may have been masked by sophisticated cognitive (and emotional) processes for complex stimuli.
