Despite their potentially central role in fostering school readiness, executive function (EF) skills have received little explicit attention in the design and evaluation of school readiness interventions for socioeconomically disadvantaged children.

This paper presents a model to guide capacity-building in state public education systems for delivery of evidence-based family and youth interventions—interventions that are designed to bolster youth competencies, learning, and positive development overall. Central to this effort is a linking capacity agents framework that builds upon longstanding state(More)
Forty-four Head Start classrooms were randomly assigned to enriched intervention (Head Start REDI-Research-based, Developmentally Informed) or "usual practice" conditions.

Examined the hypothesis that distinct parenting practices may be associated with type and profile of a child's disruptive behavior problems (e.g., oppositional, aggressive, hyperactive). Parents of 631 behaviorally disruptive children described the extent to which they experienced warm and involved interactions with their children and the extent to which(More)
This study examined developmental associations between growth in domain-general cognitive processes (working memory and attention control) and growth in domain-specific skills (emergent literacy and numeracy) across the pre-kindergarten year, and their relative contributions to kindergarten reading and math achievement. One hundred sixty-four Head Start(More)
72 fifth-, eighth-, and eleventh-grade boys and girls were interviewed to investigate developmental changes in perceptions of peer groups and group influence. Results indicated that preadolescents defined groups on the basis of common activities and social behavior and considered group influence to be greatest in these domains. Older adolescents were more(More)
This study examined the effects of social skills training and peer involvement on the peer acceptance of disliked preadolescents. 56 fifth- and sixth-grade children were identified as unaccepted by their peers and deficient in conversational skills. These children were then randomly assigned to 1 of 4 treatment conditions: (1) conversational skills training(More)
