Does social–behavioral adjustment mediate the relation between executive function and academic readiness?

Research shows that executive function and social–behavioral adjustment during the preschool years are both associated with the successful acquisition of academic readiness abilities. However, studies bringing these constructs together in one investigation are lacking. This study addresses this gap by testing the extent to which social and behavioral adjustment mediated the association between executive function and academic readiness. Sixty-nine 63–76month old children, enrolled in the last semester of the preschool year, participated in the present study. Tasks were administered to measure executive function and preacademic abilities, and teachers rated preschoolers' social–behavioral adjustment. Hierarchical regression analyses revealed that social–behavioral adaptation was a significant mediator of the effect of executive function on academic readiness, even after controlling for maternal education and child verbal ability. These findings extend prior research and suggest that executive function contributes to early academic achievement by influencing preschoolers' opportunities to be engaged in optimal social learning activities.

Social engagement and adaptive functioning during early childhood: Identifying and distinguishing among subgroups differing with regard to social engagement

This study tested the hypothesis that social engagement (SE) with peers is a fundamental aspect of social competence during early childhood. Relations between SE and a set of previously validated social competence indicators, as well as additional variables derived from observation and sociometric interviews were assessed using both variable-centered and person-centered approaches (N = 1453, 696 girls) in 4 samples (3 U.S.A., 1 Portuguese). Directly observed SE was positively associated with broad-band measures of socially competent behavior, peer acceptance, being a target of peers' attention, and also with broad-band personality dimensions. Using individual Q-items significantly associated with SE in 3 of our 4 samples, a hierarchical cluster analysis yielded a 5-cluster solution that grouped cases efficiently. Tests on relations between cluster membership and the set of social competence and other variables revealed significant main effects of cluster membership in the full sample and within each individual sample, separately. With the exception of tests for peer negative preference, children in the lowest SE cluster also had significantly lower overall social competence, personality functioning scores than did children in higher SE clusters.
