我们在时间估计任务中检查了反馈刺激后头皮记录的事件相关电位。在指示 1 秒间隔结束后 600 毫秒，受试者收到视觉、听觉或体感刺激，表明他们产生的间隔是否正确。在反馈表明表现不正确之后，出现了负偏转，其特征与选择反应时间任务中伴随错误的组件（与错误相关的负性）的特征密切对应。此外，等效偶极子分析表明，对于所有三种模式，头皮电位的分布与前扣带皮层中的局部源或辅助运动区中更分布的源一致。这些基因座与之前描述的那些与错误相关的阴性基因座密切对应。我们得出的结论是，与错误相关的消极性是参与错误检测的“遗传”神经系统活动的表现。
We examined scalp-recorded event-related potentials following feedback stimuli in a time-estimation task. Six hundred msec after indicating the end of a 1 sec interval, subjects received a visual, auditory, or somatosensory stimulus that indicated whether the interval their had produced was correct. Following feedback indicating incorrect performance, a negative deflection occurred, whose characteristics corresponded closely to those of the component (the error-related negativity) that accompanies errors in choice reaction time tasks. Furthermore, equivalent dipole analysis suggested that, for all three modalities, the distribution of the scalp potential was consistent with a local source in the anterior cingulate cortex or a more distributed source in the supplementary motor areas. These loci correspond closely to those described previously Tor the error-related negativity. We conclude that the error-related negativity is the manifestation of the activity of a "genetic" neural system involved in error detection.
