To date, studies using cross-sectional methodologies make up a majority of the literature surrounding children with autism spectrum disorders and participation in physical activity and screen time. Longitudinal studies are needed to examine how physical activity and screen time behaviors co-develop for children with and without an autism spectrum…

Fragile X syndrome (FXS) is characterized by both social approach and social avoidance. However, the age of emergence and developmental trajectory of social avoidance has not been examined. This study investigates the longitudinal developmental trajectory and dynamic nature of social avoidance in males with FXS from infancy through young adulthood…

In this paper, we examine the impact of U.S. child-care subsidies on the cognitive and behavioral development of children in low-income female-headed families. We identify the effect of subsidy receipt by exploiting geographic variation in the distance that families must travel from home to reach the nearest social service agency that administers…

That students' social and economic characteristics shape their cognitive and behavioral outcomes is well established, yet policymakers typically resist accepting that non-school disadvantages necessarily depress outcomes. Rather, they look to better schools and teachers to close achievement gaps, and consistently come up short. This report…

This article, using longitudinal data from the National Child Development Study, presents new evidence on the effects of family size and birth order on test scores and behavioral development at age 7, 11 and 16. Sibling size is shown to have an adverse causal effect on test scores and behavioral development. For any given family size, first-borns…

The article presents 30-year bibliometrical results on trends in the scope, internationality, and impact of the "International Journal of Behavioral Development" ("IJBD") from its inception in 1978 to 2007. Bibliometric data were collected using the databases PsycINFO and Social Science Citation Index (SSCI), and the "IJBD" itself. In comparison…

This volume brings together leading authorities from multiple disciplines to examine the relationship between brain development and behavior in typically developing children.

The purpose of this study was to test direct, additive, and mediation models involving family, neighborhood, and peer factors in relation to emerging antisocial behavior and social skills. Neighborhood danger, maternal depressive symptoms, and supportive parenting were assessed in early childhood. Peer group acceptance was measured in middle…

Uses national longitudinal data to explain the intergenerational transmission of divorce. Findings suggest that parental divorce elevates the risk of offspring divorce by increasing the likelihood that offspring exhibit behaviors that interfere with the maintenance of mutually rewarding intimate relationships. Offers four hypotheses for future…

Discusses the use of new statistical procedures in a study of the enduring effects of prenatal alcohol exposure upon the neurobehavioral development of some 500 children born in 1975-76. Explains how the Partial Least Squares (PLS) methodology can summarize the data powerfully while avoiding familiar inferential pitfalls. (MDM)

Reports findings of an investigation of the development of 54 children at 8 years of age with congenital rubella. Examines the relation between specific patterns of physical disability and cognitive and adaptive behavior. (ED)

Provides an overview of a longitudinal, prospective, multivariate adoption study of behavioral development and discusses the results of analyses of cognitive measures and environmental assessments as examples of the types of information that can emerge from a design of this sort. (Author/RH)

Two longitudinal studies examined patterns of reading disability in children. Results indicated that remission of reading disability was relatively common with up to 37% of reading-disabled children showing remission within a 2-year period. Results suggest that the presence of measurement errors may lead to misleading impression of the rate of…

Explored fathers' specific contribution to their children's attachment representation at various ages. Found fathers' play sensitivity to be a better predictor of the child's long-term attachment representation than the early infant-father security of attachment. (Author)
