The current study examined the association between effortful control and a well-studied neural index of self-regulation, the N2 event-related potential (ERP) component, in toddlers. Participants included 107 toddlers (44 girls) assessed at 30, 36 and 42 months of age. Participants completed a Go/NoGo task while electroencephalography data were recorded. The study focused on the N2 ERP component. Parent-reported effortful control was examined in association with the NoGo N2 ERP component. Findings suggest a positive association between the NoGo N2 component and the inhibitory control subscale of the wider effortful control dimension, suggesting that the N2 component may index processes associated with temperamental effortful control.This article is part of the theme issue 'Diverse perspectives on diversity: multi-disciplinary approaches to taxonomies of individual differences'.
本研究考察了努力控制与自我调节的一个研究充分的神经指标——N2 事件相关电位（ERP）成分之间的关系在幼儿中。参与者包括 107 名幼儿（44 名女孩），他们在 30、36 和 42 个月时接受了评估。参与者在完成 Go/NoGo 任务的同时记录了脑电图数据。研究重点关注 N2 ERP 成分。与更广泛的努力控制维度的抑制控制分量表相关联，研究报告了努力控制的家长报告与 NoGo N2 ERP 成分之间存在正相关关系，这表明 N2 成分可能反映了与气质努力控制相关的过程。本文是“多样性的多样性视角：个体差异分类的多学科方法”主题问题的一部分。
