Maturation of the prefrontal cortex (PFC) across the first few years of life is thought to underlie the emergence of inhibitory control (IC) abilities, which may play an important role in children’s early academic success. In this growth curve modeling study (N = 364), we assessed developmental change in children’s resting-state electroencephalogram (EEG) activity (6–9 Hz ‘alpha’ power) from 10 months to 4 years and examined whether the initial levels or amount of change in frontal alpha power were associated with children’s IC at age 4 and indirectly academic skills at age 6. Results indicated that greater increases in frontal alpha power across the study period were associated with better IC, and indirectly with better performance on Woodcock-Johnson tests of reading and math achievement at age 6. Similar associations between change in EEG and age 4 vocabulary were observed but did not mediate an association with academic skills. Similar analyses with posterior alpha power showed no associations with IC. Findings underscore the significance of frontal lobe maturation from infancy to early childhood for children’s intellectual development.

学龄前儿童额叶脑电成熟与抑制控制在儿童早期学业能力预测中的关系

生命最初几年前额叶皮层 (PFC) 的成熟被认为是抑制控制 (IC) 能力出现的基础,这可能在儿童早期的学业成功中发挥重要作用。在此生长曲线建模研究 (N = 364) 中,我们评估了 10 个月至 4 年儿童静息态脑电图 (EEG) 活动(6-9 Hz 'α' 功率)的发育变化,并检查了初始水平或数量额叶 alpha 功率的变化与 4 岁时儿童的 IC 和 6 岁时的学业技能间接相关。 6岁的阅读和数学成绩测试。观察到 EEG 变化与 4 岁词汇之间的类似关联,但并未介导与学术技能的关联。对后α功率的类似分析显示与 IC 没有关联。研究结果强调了从婴儿期到幼儿期的额叶成熟对儿童智力发展的重要性。
