Electrophysiological studies have shown that obsessive-compulsive disorder (OCD) is associated with hyperactive performance monitoring, as indexed by the error-related negativity (ERN). The aim of the present study was to determine whether feedback monitoring is enhanced in addition to error monitoring among young adults with obsessive-compulsive symptomatology during performance of a learning task. The ERN was equivalent in amplitude for low and high OC groups. The feedback-related negativity (FRN) was more negative following presentation of incorrect feedback relative to correct feedback for the low OC group. For the high OC group, the FRN was equivalent in amplitude for correct and incorrect feedback. Young adults with high levels of obsessive-compulsive symptoms demonstrate aberrant feedback monitoring characterised by a lack of differentiation to the valence of feedback. This pattern of results may be indicative of a cognitive bias in outcome prediction associated with obsessive-compulsive symptomatology.
电生理学研究表明，强迫症（OCD）与过度活跃的表现监测有关，表现为错误相关负波（ERN）。本研究旨在确定在执行学习任务期间，具有强迫症症状的年轻成年人的反馈监测是否除了错误监测之外还得到增强。对于低 OC 组，ERN 的幅度在低和高 OC 组中是相等的。对于低 OC 组，与正确反馈相比，呈现不正确反馈时 FRN 更负。对于高 OC 组，正确和不正确反馈的 FRN 幅度相等。具有高水平强迫症症状的年轻人表现出异常的反馈监测，其特征是对反馈的效价缺乏区分。这种结果模式可能表明与强迫症症状相关的结果预测中的认知偏差。
