错误负波（Ne/ERN）和错误正波（Pe）是事件相关脑电位（ERP）的两个成分，与动作监测和错误检测有关。为了探讨错误加工与有意识的行为自我监控之间的关系，本实验考察了在被试没有意识到的反应错误后是否观察到Ne和Pe。NE和PE措施，行为准确性，审判到审判的主观准确性判断，从参与者执行一个antisaccade任务。从而消除了许多未被察觉的、不正确的反射式扫视。与以前的研究一致，主观未感知的扫视错误几乎总是立即纠正，并与更快的纠正时间和较小的扫视大小比感知错误。重要的是，无论参与者是否意识到错误，错误的扫视之后是一个相当大的Ne。相比之下，PE是更明显的感知比未感知的错误。未察觉的错误的特点是没有postterror减缓。这些和其他结果是一致的，认为Ne和Pe反映了两个独立的错误监控过程的活动，其中只有后一个过程，反映了Pe，与有意识的错误识别和补救行动。
The error negativity (Ne/ERN) and error positivity (Pe) are two components of the event-related brain potential (ERP) that are associated with action monitoring and error detection. To investigate the relation between error processing and conscious self-monitoring of behavior, the present experiment examined whether an Ne and Pe are observed after response errors of which participants are unaware. Ne and Pe measures, behavioral accuracy, and trial-to-trial subjective accuracy judgments were obtained from participants performing an antisaccade task. which elicits Many unperceived, incorrect reflex-like saccades. Consistent with previous research, subjectively unperceived saccade errors were almost always immediately corrected, and were associated with faster correction times and smaller saccade sizes than perceived errors. Importantly, irrespective of whether the participant was aware of the error or not, erroneous saccades were followed by a sizable Ne. In contrast, the Pe was much more pronounced for perceived than for unperceived errors. Unperceived errors were characterized by the absence of posterror slowing. These and other results are consistent with the view that the Ne and Pe reflect the activity of two separate error monitoring processes, of which only the later process, reflected by the Pe, is associated with conscious error recognition and remedial action.
