为了更好地了解反应监测的早期发展以及儿童年龄和性别的影响，本研究在5至7岁的大样本(N=328)中检测了来自Go/No Go任务的行为测量和反应锁定事件相关脑电位(ERPs)。具体而言，我们考察了错误相关负性(ERN)、正确反应负性(CRN)和错误正性(Pe)，错误相关负性(ERN)仅定义在错误试验和正确试验之间的差异。总体而言，ERN、CRN和Pe在空间和时间上与成人和年龄较大的儿童的测量结果相似。即使在我们狭窄的年龄范围内，年龄较大的孩子也更快、更准确；更消极的ERN和更积极的PE与：年龄增长、准确性增加和对错误的反应时间更快相关，这表明这些增强的成分反映了对错误的更有效的反应监控。女孩比男孩更慢，更准确，尽管两性的ERP表现相似。年龄较小的儿童和女孩的特征是后视速度减慢，尽管他们没有表现出更好的后视准确性。后视减慢也与较大的Pe和后视精确度降低有关。总而言之，这些数据表明，后视减速可能与认知控制无关，可能像Pe一样，反映了对错误的定向反应。(C)2011 Wiley期刊，Inc.开发心理学杂志54：139-150,2012。
The current study examined behavioral measures and response-locked event-related brain potentials (ERPs) derived from a Go/No-Go task in a large (N=328) sample of 5- to 7-year-olds in order to better understand the early development of response monitoring and the impact of child age and sex. In particular, the error-related negativity (ERN, defined on both error trials alone and the difference between error and correct trials, or ?ERN), correct response negativity (CRN), and error positivity (Pe) were examined. Overall, the ERN, CRN, and the Pe were spatially and temporally similar to those measured in adults and older children. Even within our narrow age range, older children were faster and more accurate; a more negative ?ERN and a more positive Pe were associated with: increasing age, increased accuracy, and faster reaction times on errors, suggesting these enhanced components reflected more efficient response monitoring of errors over development. Girls were slower and more accurate than boys, although both genders exhibited comparable ERPs. Younger children and girls were characterized by increased posterror slowing, although they did not demonstrate improved posterror accuracy. Posterror slowing was also related to a larger Pe and reduced posterror accuracy. Collectively, these data suggest that posterror slowing may be unrelated to cognitive control and may, like the Pe, reflect an orienting response to errors. (C) 2011 Wiley Periodicals, Inc.
