Using a sample of individuals (277 males, 315 females) studied since birth in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development, the present study investigated how early pubertal maturation and school transition alter youth trajectories of social competence during the transition to…

To test a proposition central to J. Belsky, L. Steinberg, and P. Draper's (1991) evolutionary theory of socialization--that pubertal maturation plays a role in linking early rearing experience with adolescent sexual risk taking (i.e., frequency of sexual behavior) and, perhaps, other risk taking (e.g., alcohol, drugs, delinquency)--the authors…

It has been hypothesized that sensation seeking and impulsivity, which are often conflated, in fact develop along different timetables and have different neural underpinnings, and that the difference in their timetables helps account for heightened risk taking during adolescence. In order to test these propositions, the authors examined age…

This article proposes a framework for theory and research on risk-taking that is informed by developmental neuroscience. Two fundamental questions motivate this review. First, why does risk-taking increase between childhood and adolescence? Second, why does risk-taking decline between adolescence and adulthood? Risk-taking increases between…

Examines the reciprocal relation between parent-child distance and pubertal maturation. Analyses indicate that (1) puberty increases adolescent autonomy and parent-child conflict and diminishes parent-child closeness; and (2) parent-child distance may accelerate pubertal maturation among girls.

Findings from a study of 129 families with a firstborn child 10 to 15 years old indicated only very modest direct relations between parental well-being and signs of adolescent development, such as pubertal status, mixed-sex social relations, and reasoning skills. Relations were moderated by the strength of parents' orientation toward their work…

Examines the impact of pubertal status and timing, independent of chronological age, on the family relationships of adolescents in 204 families with a firstborn child between the ages of 10 and 15. Measures included adolescent and parental reports of closeness, confict, and autonomy and assessments of adolesents' pubertal status and pubertal…

Examined effects of three different aspects of heterosocial activity--mixed-sex activities, dating, and physical involvement with boys--on the diet patterns of adolescent girls. Found interaction between dating and menarcheal status in the prediction of dieting and disordered eating, with dating more strongly linked to dieting and disordered…
