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.
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.
