A study of 83 gay and bisexual male youths (17-23 years old) found that pubertal maturation was associated with self-reported age of first orgasm and homosexual activity and frequency of orgasms during junior high school. It concluded that gay and bisexual male youths share with heterosexual male youths a similar developmental trajectory in regard…

Each of 111 families with seventh grade daughters was observed in a family interaction task. Results indicated that conflict with parents, and especially with the mother, was more frequent shortly after menarche than at other times. Withdrawal of positive affect was associated with menarcheal status. (BC)

This study examined whether aspects of pubertal maturation in girls vary across race and ethnicity. Findings highlighted the importance of including socioeconomic factors in exploration of menarcheal differences across race/ethnicity. Perceptions of pubertal timing did not vary across racial/ethnic groups. (SD)

The psychosocial impact of puberty on changes in girls' feelings about their bodies and their sexuality is discussed. We present a model of girls' sexuality development that incorporates puberty, self, and peer systems. (Contains 2 figures.)

Adolescence is a time of considerable development at the level of behaviour, cognition and the brain. This article reviews histological and brain imaging studies that have demonstrated specific changes in neural architecture during puberty and adolescence, outlining trajectories of grey and white matter development. The implications of brain…

Background: Immediate medical assessment has been recommended for children after sexual abuse to identify physical injuries, secure forensic evidence, and provide for the safety of the child. However, it is unclear whether young children seen urgently within 72 hours of reported sexual contact would have higher frequencies of interview or…

Objective: The current study examined the prevalence and characteristics of childhood sexual abuse in a jailed-based population. Methodology: A retrospective, self-reported survey was administered over an 8-week period to a random sample of 100 men who were incarcerated in a county jail in Southeastern Texas. The survey included questions about…

Self-rating of pubertal development is the recommended method to assess puberty in large community-based surveys of adolescent development and behavior. The aim of this study was to validate for the first time pubertal self-assessment using the sexual maturation scale developed by Tanner among Black South African adolescents (n=182) aged between…

This investigation is a comprehensive acoustic study of 4 voiceless fricatives (/f [theta] s [esh]/) in English produced by adults and pre-and postpubescent children aged 6-14 years. Vowel duration, amplitude, and several different spectral measures (including spectral tilt and spectral moments) were examined. Of specific interest was the pattern…

Prior research has indicated that pubertal development and peer associations are important determinants of adolescent smoking behavior. However, more remains to be learned about "why" these variables matter or how they may be related to one another in ways that lead to the initiation of smoking. Using contractual data from the National…

Life history theorists have proposed that humans have evolved to be sensitive to specific features of early childhood environments and that exposure to different environments biases children toward development of different reproductive strategies, including differential pubertal timing. The current research provides a longitudinal test of this…

This article explores the empirical validity of the Social Interactionist (SI) perspective as an explanation of violent victimization. An additional goal is to explain why early puberty among adolescents is connected to violent victimization. Using SI, we theorize that early puberty creates unusually high levels of distress for adolescents (more…

Although the basic growth changes for teenagers are the same as they were 20 or 30 years ago, the environment in which these changes occur has changed. This book describes the characteristic changes in human behavior which take place from year to year between the ages of 10 and 14. Part 1 of the book describes the longitudinal research, which…

This paper reviews some of the maturational events that are applicable in studying psychological effects of pubertal status and timing. Nine changes are reviewed (bone, height, weight, body fat, breast, body hair, penile, testicular, and menarcheal changes) in terms of measurement techniques, psychometric properties, and intercorrelations with…

Risk factors for early adolescents' (700 between the ages of 10 to 13) delinquency were compared between groups of children high and low in childhood adversities. The samples represented young people from the two former Germanies (200 from former East and 500 from West Germany) who were interviewed in person. Additional information was gathered…
