The ERN or Ne is a component of the event-related brain potential that occurs when human subjects make errors in reaction time tasks. It is observed in response-locked averages, time-locked to the execution of the incorrect response. Recent research has reported that this component is present on correct response trials, thereby challenging the idea that the component is specifically related to error-processing. In this paper, we argue that the ERN or Ne observed on correct trials can be attributed to one or both of two factors: either there is error-processing on correct trials, and/or the response-locked averages used to derive the ERN/Ne are contaminated by negative components evoked by the stimulus. For this reason, there is no reason to abandon theories that relate the ERN/Ne to error-processing.
错误相关负波（ERN）或负性成分（Ne）是事件相关脑电位的一个组成部分，当人类受试者在反应时任务中犯错时会出现。它在反应锁定平均值中被观察到，与错误反应的执行时间锁定。最近的研究报告称，在正确反应试验中也存在这一成分，从而对该成分与错误处理有特定关联的观点提出了挑战。在本文中，我们认为在正确试验中观察到的ERN或Ne可归因于以下两个因素中的一个或两个：要么在正确试验中存在错误处理，和/或用于得出ERN/Ne的反应锁定平均值被刺激诱发的负性成分所污染。因此，没有理由摒弃将ERN/Ne与错误处理相关联的理论。
