A key task for schools is to ensure that the conditions in which learning is to take place address the biological needs of the learners. This book examines sleep needs of adolescents and discusses the implications of these needs for school starting times. This book is a collection of five articles that appeared in a special section of the Phi…

The social and interpersonal characteristics of early adolescents are described in relation to puberty and the physical and emotional changes that are experienced by the preteen. Learning characteristics for this age group include problem-solving strategies, self-directed learning, and emerging value systems. (JN)

Analysis of National Longitudinal Study of Adolescent Health data on 5,477 girls attending mixed-sex secondary schools found that early puberty and physical development that was advanced relative to age were related most strongly to "party" deviance (drinking, smoking, disorderly conduct), but also to minor and serious delinquency.…

Argues that the higher incidence of depression among adolescent females is due to the interaction of two factors: (1) girls enter early adolescence with a style of responding to frustration and distress that is less efficacious and action oriented than boys; and (2) girls begin to face certain uncontrollable stressors in early adolescence to a…

Discusses the need for sex education and the inclusion of accurate information in materials produced for young people. Materials that address sexual reproduction, puberty, teenage pregnancy, AIDS, and other sexually transmitted diseases are reviewed, and recommended titles for print and nonprint materials are listed together with resources for…

Used between-family analyses of data from adolescent twin girls to offer new evidence that early menarche is associated with earlier initiation and greater frequency of smoking and drinking. Found that association of pubertal timing with substance use could not be explained by between-family confounds, and pubertal timing influence on drinking…

Alpha-mannosidosis is characterized by mild to moderate intellectual disability (ID), moderate to severe neurosensory hearing loss, frequent infections, psychomotor disturbances and skeletal dysmorphism. For the first time, a panel of nine alpha-mannosidosis patients with psychiatric symptoms is presented. The clinical picture has several…

This document consists of three annual issues of a special subject bibliography combining adolescent sexuality, for the years 1988, 1989, and 1990, respectively. Citations for books, journal articles, and reports concerned with adolescent sexuality are grouped under such topics as: Acquired Immune Deficiency Syndrome and Human Immunodeficiency…

Research on girls' development has found that girls see the world that coheres through human relationships rather than through systems of rules, and that 12 or 13 is a watershed age for girls, a time of "central relational crisis." As their bodies enter the physiological transformations that culminate in womanhood, they face an onslaught…

Considers factors that may be involved in changes in the socialization process at puberty, and examines some central findings from the literature on pubertal changes from a socialization perspective. Pubertal maturation is expected to be accompanied with socialization problems in terms of unclear and different expectations to the developing…

Examined relation between puberty and adjustment problems in 7th through 10th-grade males. Found that, compared with less physically developed peers, more physically developed boys in grade 7 manifested more externalized hostile feelings and internalized distress in grades 8-10. Pubertal timing related to distress and hostility, even when…

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…

Examined associations between pubertal development and parent-adolescent conflict in urban, low-income African-American adolescents. Found that parents reported more verbal aggression with sons during midpuberty than early or late puberty, more violent tactics with younger than older daughters, and more "hot" discussions with early-…

We have investigated the hypothesis that stress condition will accelerate pubertal maturation in adolescent girls and that faster maturing girls will display more behavioral problems than their on-time or late-maturing peers during pubertal development. Longitudinal data were collected yearly from 1986 to 1997. Parents of 1039 French-speaking…
