Abstract

Aperiodic electroencephalography (EEG) activity is hypothesized to index biological mechanisms that underpin brain functioning. This longitudinal study characterized the developmental trajectories of the aperiodic slope (i.e., aperiodic exponent) and offset from infancy to 7 years of age in a US community sample (N = 391, 46.5% female, predominantly White; data collection 2013-2023). The study further examined whether differential developmental trajectories resulted in differential associations between child aperiodic activity and maternal anxiety symptoms. Developmental trajectories for slope and offset were nonlinear and characterized by relative increases in early childhood and a subsequent decrease or stabilization by Age 7, with variation by brain region and sex. Maternal anxiety was negatively associated with slope at 3 years and positively associated with slope at 7 years. Implications for child brain development are discussed.

儿童早期至中期非周期性脑电图活动的纵向轨迹。
非周期脑电图(EEG)活动被假设为指示支撑脑功能的生物学机制。这项纵向研究描述了美国社区样本(N = 391, 46.5%女性,以白人为主;数据收集2013-2023年)。该研究进一步调查了不同的发育轨迹是否导致儿童非周期性活动与母亲焦虑症状之间的差异关联。倾斜和偏移的发展轨迹是非线性的,其特点是在儿童早期相对增加,随后在7岁时减少或稳定,随大脑区域和性别的变化而变化。母亲焦虑与3岁时的斜率负相关,与7岁时的斜率正相关。讨论了对儿童大脑发育的影响。

期刊介绍: As the flagship journal of the Society for Research in Child Development (SRCD), Child Development has published articles, essays, reviews, and tutorials on various topics in the field of child development since 1930. Spanning many disciplines, the journal provides the latest research, not only for researchers and theoreticians, but also for child psychiatrists, clinical psychologists, psychiatric social workers, specialists in early childhood education, educational psychologists, special education teachers, and other researchers. In addition to six issues per year of Child Development, subscribers to the journal also receive a full subscription to Child Development Perspectives and Monographs of the Society for Research in Child Development.
