ABSTRACT This study examined the test–retest reliability of the error-related negativity (ERN) and error positivity (Pe) amplitudes using a Flanker task in 118 neurotypical children and 53 adults before and after latency jitter adjustments. The reliability of the ERN and Pe amplitudes was moderate for children and moderate to strong for adults. The latency variability adjustment did not improve the reliability of the ERN and Pe amplitudes for either group, suggesting that latency variability may be a trait-like measure. For comparison purposes, the reliability of the stimulus-locked ERPs was strong for correct trials, yet the reliability was weak for incorrect trials.

测试-再测试儿童和成人表现监测脑电图测量的可靠性

摘要 本研究使用 Flanker 任务对 118 名神经典型儿童和 53 名成人在潜伏期抖动调整前后的误差相关负性 (ERN) 和误差正性 (Pe) 幅度的重测信度进行了检验。ERN 和 Pe 振幅的可靠性对儿童来说是中等的，对成年人来说是中等到强的。潜伏期变异性调整并未提高任一组的 ERN 和 Pe 振幅的可靠性，这表明潜伏期变异性可能是一种类似特征的测量。出于比较的目的，刺激锁定 ERP 的可靠性对于正确的试验来说很强，但对于不正确的试验，可靠性很弱。
