The error-related negativity (ERN/Ne) and error positivity (Pe) have been associated with error detection and response monitoring. More recently, heart rate (HR) and skin conductance (SC) have also been shown to be sensitive to the internal detection of errors. An enhanced ERN has consistently been observed in anxious subjects and there is some suggestion that the ERN is related to general negative affective experience (NA). The ERN has been source localized to the anterior cingulate cortex-a structure implicated in the regulation of affective, response selection, and autonomic resources. Thus, the findings that autonomic measures and affective distress are related to response monitoring are consistent with anterior cingulate cortex function. In the present experiment, we sought to evaluate more comprehensively the relationship between self-reported negative affect and error-related physiology in a between-groups design. Results indicate that high NA was associated with significantly greater ERN and error-related SCR, and smaller Pe. These results are discussed in terms of anterior cingulate cortex function, psychopathology, and response monitoring.
错误相关负波（ERN/Ne）和错误正波（Pe）与错误检测及反应监测有关。最近，心率（HR）和皮肤电导率（SC）也被证明对内部错误检测敏感。在焦虑个体中一直观察到增强的ERN，并且有迹象表明ERN与一般负面情感体验（NA）有关。ERN的来源已定位到前扣带回皮质——一个与情感调节、反应选择和自主资源有关的结构。因此，自主测量和情感困扰与反应监测相关的研究结果与前扣带回皮质的功能一致。在本实验中，我们试图在组间设计中更全面地评估自我报告的负面情感与错误相关生理之间的关系。结果表明，高NA与显著更大的ERN和错误相关的皮肤电反应（SCR）以及更小的Pe相关。这些结果将从前扣带回皮质功能、精神病理学和反应监测的角度进行讨论。
