Learning behavioural responses and adapting them based on feedback is crucial from a young age, continuing to develop into young adulthood. This study examines the development trajectory and contributing factors from childhood to adulthood using a reversal learning paradigm. We tested 202 participants aged 10 to 22 in an online study, where they…

Loneliness becomes more prevalent as youth transition from childhood into adolescence. A key underlying process may be the puberty-related increase in biological stress reactivity, which can alter social behavior and elicit conflict or social withdrawal (fight-or-flight behaviors) in some youth, but increase prosocial (tend-and-befriend) responses…

Though often discussed as a discrete event, puberty comprises one segment of a larger developmental continuum and is notable for rapid transformation across a multitude of domains. While an earlier timing of puberty relative to peers stands as one of the most well-replicated antecedents of adolescent difficulties for girls, findings have been less…

Evolutionary-minded developmentalists studying predictive-adaptive-response processes linking childhood adversity with accelerated female reproductive development and health scientists investigating the developmental origins of health and disease (DOoHaD) may be tapping the same process, whereby longer-term health costs are traded off for…

Developmental and life course studies of young adult identities have focused on 2 dimensions: subjective age and psychosocial maturity. This study examines the developmental synchrony of these 2 processes. In a longitudinal sample of young adults from Add Health (ages 18-22), a person-centered analysis of indicators of these dimensions identified…

Background: Dehydroepiandrosterone (DHEA) is an adrenal androgen which is stress responsive and a trigger for pubertal maturation. Studies on basal DHEA suggest protective benefits against anxiety and depression, yet it is unknown whether DHEA responsivity is protective. Methods: Structural equation modeling examined salivary DHEA responses to a…

On March 23 and 24, 1998, the Forum on Adolescence gathered an interdisciplinary group of researchers and practitioners to review the state of knowledge about adolescent development at a workshop entitled "New Research on the Biology of Puberty and Adolescent Development." This workshop focused both on puberty, a set of physical changes rooted in…

The relationship between self-esteem and pubertal maturation is examined based on results of the first two years of a six-year naturalistic longitudinal study of the ecology of self-esteem during adolescence. Results are discussed in terms of the onset and timing of pubertal maturation and its influence on self-esteem. (Author/GK)

The impact of experiencing multiple life changes in early adolescence was studied. Subjects were students followed from sixth to seventh grade and variables analyzed were self-esteem, academic grade-point average, and participation in extra-curricular activities. (PCB)

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…

To extend research linking pubertal timing and adolescent health outcomes, this study examines boys' pubertal timing and subsequent interpersonal success and health behaviors in mid adulthood. Past research has shown that boys' pubertal timing is associated with both positive and negative developmental outcomes in the short term, and so it is…

Discusses the origins and context of adolescence as a cultural phenomenon and illustrates how rites of passage can nurture healthy developmental changes in adolescents. Describes and evaluates the application of a rite of passage during a backpacking experience that was designed to usher teens from adolescence to adulthood in a Christian context.…

As a part of a series of books written by physicians for their patients, this publication explains heredity, birth, and growth patterns to pre-teen children. The chapters are written in language appropriate for children moving from childhood into their teens and deal with topics like: cells, conception, prenatal development, puberty, and changing…

Research consistently correlates early pubertal timing with problem behaviors. Social and biological processes, which differ among ethnic groups, may also explain the relationship between pubertal timing and delinquency. Interviews with 5,000 boys ages 11 to 17 showed that early pubertal timing predicts nonviolent and violent delinquency for Anglo…

Questionnaire and interview findings from 36 white middle-class adolescent boys found that the first ejaculation was psychologically meaningful but socially invisible. Those who felt more prepared expressed more positive feelings and coped better. Psychosocial and developmental difficulties in sexual education for young males are discussed. (SLD)
