This study examined relations between intentional self-regulation (ISR) and executive functions (EFs) among 84 Icelandic youth in Grade 6 (mean age 11.7 years; 51% girls) and their contributions to healthy and problematic outcomes a year later. ISR was indicated by the Selection, Optimization and Compensation model (SOC) and Self-Regulated…

Early life adversity influences the diurnal cortisol rhythm, yet the relative influence of different characteristics of adversity remains unknown. In this study, we examine how developmental timing (childhood vs. adolescence), severity (major vs. minor), and domain of early life adversity relate to diurnal cortisol rhythms in late adolescence. We…

Cross-sectional research has demonstrated the overrepresentation of gender dysphoria in children and adults with autism spectrum disorder. However, the predictors and underlying mechanisms of this co-occurrence remain unclear. This follow-up study aimed to explore baseline (childhood/adolescence) predictors for the follow-up (adulthood)…

Family factors and adolescent life satisfaction have profound effects on later behavior. The present study examined the effects of family cohesion and life satisfaction on internalizing (depression and self-esteem) and externalizing (deviance) outcomes among adolescents. Moreover, this study also viewed internalizing outcomes as conduits that…

Identity development can be challenging for adolescents, particularly those from immigrant families who are required to make sense of their identity whilst accommodating themselves into different cultures. For second-generation ethnic minority adolescents, these identity formation processes may range from harmony/effectiveness to conflict/stress,…

The present study examined longitudinal associations between preschoolers' executive function (EF) and adult educational attainment, impulse control, and general health directly and through its cascading effects on childhood and adolescent EF using a large, national, and prospective longitudinal sample of participants. Data were drawn from the…

Adolescence is a period of rapid cognitive change, including an initial increase in speed of cognitive processing and a more gradual increase in efficiency of cognitive processing. This study examined how neurophysiological changes associated with adolescent development can inform the design of game-based executive function (EF) training. Two…

Many prosocial behaviors involve social risks such as speaking out against a popular opinion, bias, group norm, or authority. However, little is known about whether adolescents' prosocial tendencies develop over time with their perceptions of social risks. This accelerated longitudinal study used within-subject growth-curve analyses to test the…

Adolescence is by definition an "age of risk", irrelevant if you substantiate such a claim experientially or empirically. Mid-adolescence is the period where the processes of both neural and socio-emotional maturation are linked with an increase in both exploratory and health-risk behaviors. The present study, using a cross-sectional…

Objectives: Adolescents endeavor to meet their social needs, to be accepted and to develop close friendship relationships. However, quality and close relationships may not always be possible. Identity development may be affected if adolescents cannot be included in social groups and cannot establish quality friendship relationships. This can be…

Although many relatives use video chat to keep in touch with toddlers, key features of adult-toddler interaction like joint visual attention (JVA) may be compromised in this context. In this study, 25 families with a child between 6 and 24 months were observed using video chat at home with geographically separated grandparents. We define two types…

Sense of belonging is an essential element of a high-quality 4-H program. However, little research exists quantifying sense of belonging among 4-H club members. We measured perceived sense of belonging among Florida 4-H members in middle and high school as well as seven factors that influenced continued participation in 4-H. Parental involvement,…

Background: Understanding the parental influences on the career development of non-engaged youth (NEY) has been an underdeveloped research area. Furthermore, psychometrically valid and reliable tools for assessing how parents of NEY support their children in dealing with career issues remain largely unavailable in academia. Objective: This…

Adolescence is important for the development of achievement motivation, including achievement goal pursuit. Longitudinal research is scarce on adolescents' goal development and its implications for academic outcomes. In our research, we first present a systematic review of findings on achievement goals in adolescence. Then we report 2 longitudinal…

Sleep spindles are related to sleep-dependent memory consolidation and general cognitive abilities. However, they undergo drastic maturational changes during adolescence. Here we used a longitudinal approach (across 7 years) to explore whether developmental changes in sleep spindle density can explain individual differences in sleep-dependent…
