Integrating behavioral and neurophysiological measures has created new and advanced ways to understand the development of self-regulation. Electroencephalography (EEG) has been used to examine how self-regulatory processes are related to frontal alpha power during infancy and early childhood. However, findings across previous studies have been inconsistent. To address this issue, the current meta-analysis synthesized all prior literature examining associations between individual differences in self-regulation and frontal EEG alpha power (baseline and/or task). In total, 23 studies consisting of 1275 participants between 1 month and 6 years of age were included, which yielded 149 effect sizes. Findings of the three-level meta-analytic model demonstrated a non-significant overall association between self-regulation and frontal alpha power. Yet, significant moderating effects were found for self-regulation construct (emotion regulation, effortful control, executive function), self-regulation measurement (behavioral task, computer assessment, lab observation, questionnaire), and children's mean age. Self-regulation was only significantly correlated with frontal alpha power when studies focused on the executive functioning construct. Moreover, the use of behavioral tasks or questionnaires and a higher mean age of the children resulted in small but significant effect size estimates. Higher frontal alpha power values were related to higher order top-down mechanisms of self-regulation, indicating that these mechanisms might become stronger when the frontal cortex is sufficiently developed. The findings of the current meta-analysis highlight the importance of longitudinal analyses and multimethod approaches in future work to reach a more comprehensive understanding of the role of frontal EEG alpha activity in the etiology of individual differences in early self-regulation.

婴儿期和幼儿期的自我调节和额叶脑电图α活动：多层次荟萃分析
整合行为和神经生理学措施创造了新的和先进的方法来理解自我调节的发展。脑电图 (EEG) 已被用于检查自我调节过程如何与婴儿期和幼儿期的额叶 alpha 功率相关。然而，以往研究的结果并不一致。为了解决这个问题，当前的荟萃分析综合了所有先前的文献，研究了自我调节的个体差异与额叶脑电图 alpha 功率（基线和/或任务）之间的关联。总共纳入了 23 项研究，包括 1275 名 1 个月至 6 岁的参与者，产生了 149 个效应值。三级元分析模型的结果表明自我调节与额叶阿尔法功率之间的整体关联不显着。然而，发现自我调节结构（情绪调节、努力控制、执行功能）、自我调节测量（行为任务、计算机评估、实验室观察、问卷调查）和儿童平均年龄有显着的调节作用。当研究集中在执行功能结构上时，自我调节仅与额叶阿尔法功率显着相关。此外，使用行为任务或问卷以及较高的儿童平均年龄导致了较小但显着的效应量估计。较高的额叶 alpha 功率值与较高阶的自上而下的自我调节机制有关，表明当额叶皮层充分发育时，这些机制可能会变得更强。
