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…

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…

Very little is known about the neural underpinnings of language learning across the lifespan and how these might be modified by maturational and experiential factors. Building on behavioral research highlighting the importance of early word segmentation (i.e. the detection of word boundaries in continuous speech) for subsequent language learning,…

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…

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…

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.…

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…

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…

Past research indicates a significantly higher prevalence of early sexual maturation in African American (AA) girls, which is associated with a number of psychological and behavioral problems as well as with health problems such as childhood obesity and diabetes. Both nutrition and body image perceptions have never before been empirically…

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…

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)
