Connections between prosociality and antisocial behaviors have been recognized; however, little research has studied their developmental links longitudinally. This is important to illuminate during early adolescence as a sensitive period for social development in which prosociality could protect against the development of later antisocial…

Antisocial peer behavior and low parental knowledge of adolescents' activities are key interpersonal risk factors for adolescent substance use. However, how the magnitude of associations between these risk factors and substance use may vary across adolescence remains less well understood. The present study examined the age-varying associations of…

Age is one of the most robust correlates of criminal behavior. Yet, explanations for this relationship are varied and conflicting. Developmental theories point to a multitude of sociological, psychological, and biological changes that occur during adolescence and adulthood. One prominent criminological perspective outlined by Gottfredson and…

This article considers claims now being made about "the adolescent brain". It points out why some of those claims are problematic for methodological, social and philosophical reasons. Attention is given to how some "youth experts" and others have used this research by relying on and reinforcing prejudicial stereotypes about young people as…

To describe trajectories of aggressive behaviors for adolescents living in rural areas, we compared the patterns, timing and sex differences in development of physical and social aggression using five waves of data collected from youth in school surveys administered over 2.5 years. The sample (N = 5,151) was 50.0% female, 52.1% Caucasian and 38.2%…

Delinquency intervention and research have undergone changes in recent years. One new line of research has been aimed at mapping out juvenile criminal careers. Findings from this research suggest that involvement in technically delinquent activity may be a transitory, developmental phenomenon related to adolescence. Youth appear to be increasingly…

Affective disorder is characterized by maladaptive changes in mood, attitudes, energy level, and physical status. These changes constitute the basic dimensions of depression. Depression results from a combination of genetic and experiential factors. There are sex differences and age differences with regard to depression, and there is a high…

The study of the role of students' interest in their learning has seen a resurgence in the past 20 years. This chapter examines the ways in which adolescents' interests develop, differ from those of younger children, and contribute to their developing sense of self. The chapter helps to explain why many adolescents lack academic interests and how…

A dual taxonomy is presented to reconcile two incongruous facts about antisocial behavior, that it shows impressive continuity over age, but its prevalence changes dramatically over age, increasing almost tenfold during adolescence. Studying delinquents earlier in life may yield more information about the causes and antecedents of antisocial…

Many of today's youngsters are alienated, poor achievers with drug dependencies. Recent "liberating" developments for adults, such as simplified divorce procedures, have lessened adult input in children's lives. Support of children from public institutions wanes as political conservatism increases. Effective solutions are sorely needed on the…

Objective: Antisocial behavior that begins in mid- to late adolescence does not fit into commonly accepted taxonomies of antisocial behavior, yet it clearly exists. This study examined how this course of antisocial behavior compares with persisting (beginning by early adolescence and continuing through late adolescence) and desisting (stopping by…

It was hypothesized that antisocial behavior and deviant peer involvement assessed prior to puberty, at grade four, would predict initiation of sexual intercourse by grade nine. The hypotheses were tested on a sample of 201 boys who were at risk for delinquency. The subjects participated in an extensive multiple method/agent assessment for both…

A growing body of research has linked exposure to violence to violent behavior, but few studies have examined the impact of the timing of exposure to violence on violent behavior among inner city, minority youth. Theoretical insights derived from developmental psychology and psychopathology (DPP) and Agnew's general strain theory (GST) give…

This article seeks to elucidate the trajectory of development in adolescents and adults with autism. Prospective, retrospective, and cross-sectional studies are reviewed to reveal the manifestation of and changes in the core symptoms of autism in adolescence and adulthood. Comparing children with adolescents and adults, modest degrees of symptom…
