Event-related potential (ERP) studies of error-processing have characterized the error-related negativity (ERN) as a negative deflection occurring after the commission of an error at frontocentral sites. The ERN has frequently been examined in the context of individual differences and has been proposed as a neurobehavioral risk marker. Given this, it is important to characterize the psychometric properties of the ERN across multiple tasks as a function of increasing trial numbers in order to establish task-specific psychometric properties for efficient assessments in clinical or applied settings. The current study examines the internal reliability of the ERN across the flankers, Stroop, and go/no-go tasks as a function of error number. Results suggest that although the tasks all elicit the ERN reliably, important psychometric differences emerged indicating that the flankers task might be prioritized when assessing the ERN.
与错误处理相关的事件相关电位（ERP）研究将错误相关负波（ERN）描述为在额中央部位出现错误后发生的负向偏转。ERN经常在个体差异的背景下进行研究，并被提议作为一种神经行为风险标志物。鉴于此，重要的是要将ERN在多个任务中的心理测量特性表征为试验次数增加的函数，以便建立特定于任务的心理测量特性，用于临床或应用环境中的有效评估。本研究考察了ERN在侧翼干扰任务、斯特鲁普任务和停止信号任务中的内部信度作为错误数量的函数。结果表明，尽管所有任务都能可靠地诱发ERN，但出现了重要的心理测量差异，这表明在评估ERN时，侧翼干扰任务可能是优先选择的。
