Based on the temporal framework of transition experiences, this study tested time-graded patterns of family resource effects on children's and early adolescents' psychological adjustment during a time of multiple transitions. Using data of a longitudinal study including 2,020 German children covering the age span between 8 and 12 (n[subscript…

Social anxiety is a common mental disorder with an average age of onset in early adolescence. Current theories focus largely on risk factors that are present from early in life, but reasons for onset of the disorder as youth move into adolescence are rarely discussed. We recently proposed a model of the onset of certain mental disorders during the…

Links among concurrent and longitudinal changes in pubertal development and empathic ability from ages 10 to 13 and neural responses while witnessing peer rejection at age 13 were examined in 16 participants. More advanced pubertal development at age 13, and greater longitudinal increases in pubertal development, related to increased activity in…

Girls in mixed-sex schools who experienced early menarche were at greater risk for delinquency than those who experienced late menarche. Individual differences in delinquency were more stable across time among girls in mixed-sex schools than among those in all-girl schools. (BC)

Assessed differences in masculinity, femininity, and sex role attitudes in adolescent girls and boys, and the relation of pubertal timing to intensification of those attitudes. Found that sex differences in masculinity and sex role attitudes increased with age. Pubertal timing was unrelated to masculinity, femininity, and sex role attitudes. (BC)

A longitudinal study of early adolescents examined gender differences in attitude and behavior, as well as the effects of pubertal change, parental expectations, and parental support. It was hypothesized that sex differences would emerge during preadolescence and that males' and females' rates of change would be significantly different. Subjects…
