There is increasing interest in examining the development of frontal EEG power in relation to self-regulation in early childhood. However, the majority of previous studies solely focuses on the brain's alpha rhythm and little is known about the differences between young boys and girls. The aim of the current study was therefore to gain more insight into the neural mechanisms involved in the emergence of self-regulation. The sample consisted of 442 children and data were collected at approximately 5 months, 10 months, and around 3 years of age. Latent growth curve models indicated that,while the neurobiological foundations of self-regulation are established during infancy,it is the maturation of the frontal alpha rhythm that contributes to variations in both observed and parent-reported self-regulation. In addition, it appears that boys might have a greater reliance on external regulation than girls during early childhood, as evident by higher scores of girls on both measures of self-regulation. More insight into the role of external regulators in brain maturation can help to implement interventions aimed at establishing bottom-up self-regulatory skills early in life, in order to provide the necessary foundations for the emergence of top-down self-regulatory skills in the preschool period.
人们越来越关注在儿童早期研究与自我调节相关的额部脑电图功率的发展。然而，之前的大多数研究仅关注大脑的 alpha 节律，对于男女儿童之间的差异知之甚少。因此，本研究旨在深入了解自我调节出现过程中的神经机制。该样本由 442 名儿童组成，数据分别在大约 5 个月、10 个月和 3 岁左右收集。潜在增长曲线模型表明，尽管自我调节的神经生物学基础在婴儿期就已建立，但正是额部 alpha 节律的成熟促进了观察到的和父母报告的自我调节的变化。此外，似乎男孩在幼儿期比女孩更依赖外部调节，这两个自我调节的测量指标都显示女孩的分数更高。深入了解外部调节者在大脑成熟中的作用，可以帮助实施旨在早期生活中建立自下而上的自我调节技能的干预措施，为学龄前时期自上而下的自我调节技能的出现提供必要的基础。
