Most methods used to quantify event-related potential (ERP) data were developed for use with typical adult populations. Questions regarding how these methods apply to child ERP data remain. Here, we focused on two widely used ERP scoring methods, namely, time-window mean amplitude and peak amplitude measures, for two ERP error monitoring components, the error-related negativity (ERN) and the error positivity (Pe), collected from Kindergarteners during a child-friendly cognitive control task (N = 170). We first established the presence of error-related ERPs and examined the relations between ERP scores and children's behavioral task performance. We then assessed the data quality (precision) of mean and peak ERP amplitude scores at the level of individual participants using the standardized measurement error of ERPs. We also compared the effects of choosing baseline correction periods that were relatively distal versus proximal to responses on data quality. Across each of these analyses, we found that time-window mean amplitude scoring was comparable to, and in some cases outperformed, peak amplitude scoring. In addition, the proximal baseline provided higher data quality than the distal baseline. We conclude with specific recommendations regarding the scoring and baseline correction for ERP data collected from young children.
大多数用于量化事件相关电位（ERP）数据的方法是为典型成年人群开发的。这些方法如何应用于儿童ERP数据仍存在疑问。在此，我们聚焦于两种广泛使用的ERP评分方法，即时间窗口平均振幅和峰值振幅测量，用于从幼儿园儿童在一项适合儿童的认知控制任务中收集的两种ERP错误监测成分，即错误相关负波（ERN）和错误正波（Pe）（N = 170）。我们首先确定了错误相关ERP的存在，并检查了ERP分数与儿童行为任务表现之间的关系。然后，我们使用ERP的标准化测量误差，在个体参与者层面评估平均和峰值ERP振幅分数的数据质量（精度）。我们还比较了选择相对于反应较远与较近的基线校正期对数据质量的影响。在这些分析的每一项中，我们发现时间窗口平均振幅评分与峰值振幅评分相当，并且在某些情况下优于峰值振幅评分。此外，近端基线比远端基线提供更高的数据质量。我们最后针对从幼儿收集的ERP数据的评分和基线校正提出了具体建议。
