错误相关负波(ERN)代表从头皮电极记录到的与监测活动相关的神经反应。它最有可能产生于前扣带回皮质(ACC)。当参与者在退化的刺激条件下执行视觉2选择反应时任务时，测量ERN以及行为和感知的准确性。无论行为的准确性如何，ERN的幅度(在反应时测量)与感知的行为不准确性(在试验结束时测量)是不同的。由于过早的反应恐惧而产生的错误(被认为是错误)与较大的ERN有关。由于数据限制造成的错误(存在不确定性的恐惧)与较小的ERN相关。这些结果和其他结果符合以下建议，即执行情况监测--如雇员再培训网所表明的--涉及对适当答复的陈述与实际作出的答复之间的比较。
The error-related negativity (ERN) represents a neural response, recorded from scalp electrodes, that is associated with monitoring activities. It is most likely generated in the anterior cingulate cortex (ACC). Measures of the ERN, and of behavioral and perceived accuracy, were obtained from participants while they performed a visual 2-choice reaction time task under degraded stimulus conditions. Irrespective of behavioral accuracy, the amplitude of the ERN (measured at the time of the response) covaried with the perceived inaccuracy of the behavior (measured at the end of the trial). Errors due to premature responding terrors perceived as errors) were associated with large ERNs. Errors due to data limitations terrors about which there was uncertainty) were associated with smaller ERNs. These and other results are consistent with the proposal that performance monitoring, as manifested by the ERN, involves a comparison between representations of the appropriate response and the response actually made.
