Introduction: The Moral Foundations Theory (MFT) identifies innate moral foundations that drive moral judgment, and are assumed to mature at different phases throughout development. However, core developmental aspects of moral foundations, such as normative age and gender differences from an MFT perspective, remain relatively unexplored,…

Studies of reward effects on behavior in adolescence typically rely on performance metrics that confound myriad cognitive and non-cognitive processes, making it challenging to determine which process is impacted by reward. The present longitudinal study applied the diffusion decision model to a reward task to isolate the influence of reward on…

A growth mixture modeling (GMM) analysis of neutralization scores in 1,830 youth across six waves of data revealed evidence of a three-class model in which moral neutralization either increased (low accelerating), decreased (high decelerating), or remained the same (moderate stable) over time. Controlling for age, sex, race, group assignment, and…

Connections between prosociality and antisocial behaviors have been recognized; however, little research has studied their developmental links longitudinally. This is important to illuminate during early adolescence as a sensitive period for social development in which prosociality could protect against the development of later antisocial…

This study analyzed the factorial structure of motor competence tests designed to evaluate motor development among adolescents, focusing on the two main dimensions of coordination and motor control. To this end, we randomly sampled 1,026 adolescents (45.3% males; 45.7% females, age 13.75 years, SD = 1.28). Participants completed the…

Individuals aged 12 to 18 are establishing housing connections that could significantly impact their future housing choices when they are particularly susceptible to external influences. Recognizing the impact of early life experiences can enhance educational initiatives to assist adolescents in making more informed housing decisions. The research…

The current longitudinal study examined the predictive associations between the development of future perceptions in adolescence and depressive symptoms in adolescence and early and middle adulthood. Participants (N = 1,527; 48.3% female; broadly representative of Western Germany with respect to race/ethnicity and socioeconomic status) were…

Developmental changes in self-regulation are theorized to underlie adolescents' engagement in risky behaviors, physical health, mental health, and transition to adulthood. Two central processes involved in self-regulation, self-management (i.e. planning, concentration, and problem-solving) and disinhibition (e.g. distractibility and impulsivity)…

This study using PROSPER data (N = 977, age 11.5-age 15) investigated the longitudinal within-family associations between parent reported parental monitoring and adolescent aggression. Importantly, this study is the first one to examine parent gender and adolescent gender differences on these within-family associations. Results differed between…

This study coordinates moral value development in adolescence, parenting style, and gender with issues of stability and specificity. The primary research question asked whether parenting styles of mothers and fathers influence the development of adolescent moral values, and secondary research questions asked whether adolescent moral values were…

Economic growth is dependent on well-skilled human capital. Technical and Vocational Education and Training (TVET) programmes are paramount in provision of the requisite capabilities which encompass both academic and non-academic skills also known as whole youth development (WYD) skills. Youths leaving training institutions in Kenya experience…

The architecture of sleep undergoes distinct changes during childhood and early adolescence. Slow wave sleep is involved in memory processing and may support active consolidation of newly encoded representations to support the formation of abstracted "gist" memories. Here, we examined sleep and overnight memory formation in German school…

We developed age- and sex-specific smoothed percentiles for vertical and long jump, as well as vertical jump power, in healthy 10-18 year olds (n = 529, 47.1% female). Jump height and distance were measured and vertical jump power was assessed via mechanography. LMS regression was used to create smoothed age-specific reference curves, separated by…

Parent-child communication concerning sexual and reproductive health (SRH) has significant potential to reduce children's risky sexual behaviour. Despite these benefits, few parents communicate with their children about SRH issues in Uganda. Using multi-stage stratified sampling in a cross-sectional survey, we estimated the prevalence and…

This study aims to examine the impact of a school-based intervention on life skills and personal development among adolescents in Kosovo. It responds to the educational shift toward competence-based learning outlined in the new Kosovo curriculum. The research adopts a quasi-experimental design with pre-and post-tests to examine changes in…
