The complexity of interactions in team sports requires players to have excellent technical skills. The purpose of this study was to longitudinally investigate the predictive value of motor competence (MC) on soccer-specific skills development. Participants were n = 79 boys, aged between 5.89 and 14.63 years at baseline followed for 3 consecutive…

Distractibility is the propensity to behaviorally react to irrelevant information. Although children are more distractible the younger they are, the precise contribution of attentional and motor components to distractibility and their developmental trajectories have not been characterized yet. We used a new behavioral paradigm to identify the…

The authors examined the degree to which callous-unemotional traits and narcissism predict relational aggression, social aggression, and prosocial skills in a sample of 79 adolescent offenders (13-18 years old; 26% girls; 74% boys) attending a school for youth with behavior disorders in the Mid-Atlantic United States. Narcissism made a significant…

This study examined the predictive ability of the medicine ball chest throw and vertical jump for muscular strength and power in adolescents. One hundred and ninety adolescents participated in this study. Participants performed trials of the medicine ball chest throw and vertical jump, with vertical jump peak power calculated via an estimation…

The purpose of the study is to explore whether a multidimensional profiling approach can be useful in predicting a table tennis player's actual and future (one year later) performance. Data on anthropometrics, age from peak height velocity, motor-skills, psychological skills and training histories were gathered among Scottish elite youth male…

The research conducted deals with the problem of development of personal maturity in adopting parents. The objectives of the research are to describe the content foundation of the adopting parents' personal maturity represented by motivational and value-related, emotional, cognitive and activity-related components, to prove the influence of…

Infants who have more power within the gamma frequency range at rest develop better language and cognitive abilities over their first 3 years of life (Benasich et al., 2008). This positive trend may reflect the gradual increase in resting gamma power that peaks at about 4 years (Takano & Ogawa, 1998): infants further along the maturational…

It is well-known that college students are at an increased risk for alcohol use and binge drinking compared to their same-age peers who are not in college. We use Moffitt's developmental taxonomy, specifically, her discussion of adolescence-limited offending, to contextualize this finding regarding this minor form of deviance. We also incorporate…

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…

Growth, maturation, and development dominate the daily lives of children and adolescents for approximately the first 2 decades of life. Growth and maturation are biological processes, while development is largely a behavioral process. The 3 processes occur simultaneously and interact. They can be influenced by physical activity and also can…

Adolescence is a developmental period characterized by intense changes, which impact the interaction between individuals and their environments. Moral reasoning (MR) is an important skill during adolescence because it guides social decisions between right and wrong. Identifying the cognitive underpinnings of MR is essential to understanding the…

The structure of the human brain changes in several ways throughout childhood and adolescence. Perhaps the most salient of these changes is the strengthening of white matter tracts that enable distal brain regions to communicate with one another more quickly and efficiently. Here, we sought to understand whether and how white matter changes…

It has been unclear whether adolescent deliberate self-harm (DSH) is more associated with substance use or with characterological impairments. Multivariate determination of (N = 114 Scottish adolescents) ever engaging in DSH (Youth Risk Behavior Survey) from alcohol use, other substance use, and immature defense mechanism use (Defense Style…

Subjective age generally refers to the age that one feels. In a cross-sectional questionnaire study of 245 adolescents ages 10-14 years, we examined (a) whether, and when, a cross-over in subjective age occurs, (b) differences in subjective age among pubertal timing groups, (c) correlations between subjective age and each of desired age and five…

Improvement in source memory performance throughout development is thought to be mediated by strategic processes that facilitate the retrieval of task-relevant information. Using event-related potentials (ERPs), we examined developmental changes in these processes during adolescence. Adolescents (13-14 years) and adults (19-29 years) completed a…
