We report an analysis of the componential structure of the event-related potentials (ERPs) elicited when 8-10-year-old children err. We demonstrated previously that the positive deflection that follows the error-related negativity (ERN) in young adults is a combination of two ERP components, a fronto-central positive component and a P300. As these findings affect the interpretation of error-related ERP data, it is essential to determine if the componential structure of the ERPs elicited by children's errors is similar to that found in young adults. The results of the current study confirm that, as is the case in adults, both an ERN and a fronto-central positivity are elicited by errors committed by children. In contrast to what has been previously found in adults, errors committed by children elicited a central positivity in addition to a parietal negativity that was elicited by correct responses.
我们报告了对 8-10 岁儿童犯错时诱发的事件相关电位（ERPs）的成分结构的分析。我们之前已经证明，在年轻人中，紧随错误相关负波（ERN）之后的正偏转是两个 ERP 成分的组合，即额中央正成分和 P300。由于这些发现影响了对错误相关 ERP 数据的解释，因此必须确定儿童错误所诱发的 ERPs 的成分结构是否与年轻人相似。当前研究的结果证实，与成年人一样，儿童犯错时既会引起 ERN，也会引起额中央正波。与之前在成年人中发现的情况不同，儿童犯错时会引起中央正波，而正确反应时则会引起顶叶负波。
