Keeping it together: Hourly dynamics of children’s behavioral regulation at school in a decades-long cohort study.

Though theoretical accounts describe self-regulation as dynamic, empirical studies typically rely on static measures that fail to capture changes in self-regulation from day to day or moment to moment. As a result, little is known about how or why children’s self-regulation may vary within-person, despite clear relevance for educators. In this paper, we capitalized on repeated observations from wearable devices to test the idea that daily increases in activity (DIA) across the school day could reflect a school-age child’s inability to regulate their physical activity to be appropriate to the school setting. In a national sample followed from birth to age 26 (N = 747; 49% female, 76% White, 13% Black, 6% Hispanic, 5% Other), children showing greater DIA in third grade, objectively measured using actigraphy at school and charted across hourly intervals, were rated as more impulsive and disruptive by teachers and classroom observers, had lower academic achievement in high school (β = -0.11), and completed fewer years of education as adults (β = -0.05). These findings reveal a temporal dimension to children’s behavioral regulation at school. Findings suggest that children’s behavioral regulation, proxied by the ability to inhibit motor activity, deteriorates across the school day and that children who can sustain behavioral regulation for longer go on to greater educational success long-term. Findings also reveal temporal patterns of behavior in third grade that motivate future investigations into daily experiences that could restore children’s behavioral regulation.
