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…

The purpose of this Research-to-Resource article is to provide choral directors a short, practical guide to working with male singers throughout their voice change using research-based strategies. Practical recommendations about vocal range assessment, music selection, and vocal warm-ups are provided.

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…

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…

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…

The association of pubertal maturation with internalizing and externalizing symptoms was examined with a sample of 867 African-American 10-12-year-old children. Children reported their pubertal development status and timing using a self-report questionnaire, and symptoms were assessed through diagnostic interviews with the children and their…

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…
