Background: Specific learning experiences are vital for athletes to continuously interact with developing "knowledge of" the performance environment, through the refined design of representative learning contexts (ecological paradigm), and appropriate didactical interventions (constructivist paradigm). Although there is a…

The purpose of the current study was to use the infant sibling design to explore whether proband traits of autism and ADHD could provide information about their infant sibling's temperament. This could help us to gain information about the extent to which infant temperament traits are differentially associated with autism and ADHD traits. We used…

To date, studies using cross-sectional methodologies make up a majority of the literature surrounding children with autism spectrum disorders and participation in physical activity and screen time. Longitudinal studies are needed to examine how physical activity and screen time behaviors co-develop for children with and without an autism spectrum…

Background: School-based physical education has been associated with a multitude of potential learning outcomes. Representatives of a public health perspective suggest that promoting physical activity in and outside the context of school is an important endeavour. While the importance of behavioural skill training to improve (motor) learning is…

In this article, we aim to shed light on a technique to study intra-individual variability that spans the time frame of seconds and minutes, i.e., micro-level development. This form of variability is omnipresent in behavioural development and processes of human experience, yet is often ignored in empirical studies, given a lack of proper analysis…

The present study examined how parental political attitudes, parenting styles, and classroom characteristics predict adolescents' political alienation, as feelings about the individual's ability to affect the political system's performance at the individual level. Participants were 463 families that included mothers, fathers, and their adolescent…

This paper explores some key findings from the recent two-year evaluation of a national pilot to introduce Restorative Practices (RP) in Scottish schools. A Restorative approach emphasises the human wish to feel safe, to belong, to be respected and to understand and have positive relationships with others. It recognises the fundamental importance…

Examines whether there are gender differences in changes in the aggregate level and individual stability of conduct problems from early adolescence to early adulthood. Analyzes self-reported data from a study of Norwegian adolescents. Analyses showed that involvement in conduct problems for both genders peaked in mid-adolescence. In the long term,…

Considers the relationship between self-esteem and smoking in youth by analyzing survey data of two Scottish samples of 13 to 14-year-olds (N=2,900). The findings for peer groupings, self-esteem, and smoking indicate that young people who were socially isolated report both lower self-esteem and smoking prevalence, while peer-oriented youth report…

A study of 571 Australian children (ages 4-18) with mental retardation investigated potential behavioral risk factors for injury. Results found the prevalence of potential injury risk behaviors to be higher than for typical children and that the behavioral injury risk patterns reflected those seen in younger aged typical children.

Examined key components of the "New Look" at adolescent imaginary audience and personal fable constructs. Found that only the invulnerability and omnipotence subscales of the New Personal Fable Scale were highly related. Boys were found to believe more strongly in their own uniqueness, invulnerability, and omnipotence than were girls.…

Reports the third wave of a longitudinal study that followed 106 15-year-olds from their last compulsory year at school for 22 months. Study shows that this is a period of considerable flux in smoking behavior. Highlights the role of friendship groups and social contexts and suggests that smoking prevention programs should be developed to meet the…

This study involves a two-year longitudinal investigation of adolescent participation in unstructured youth recreation centres and the development of antisocial behaviour. Participants were 1163 adolescents who represented 92% of all eighth-grade students in the town of Orebro, Sweden, during the fall of 1999. Antisocial young people and those…

Utilizes the Perspectives on Adolescent Decision-Making Questionnaire to study the transition to adolescence and the changes it involves for the family. The instrument examines 21 issues that can lead to conflict. The instrument was completed by 500 Italian adolescents ages 13 and 15. Sensitivity to age and sex differences was examined.…

This study examined the relationship between adolescents' academic and non-academic self-regulation (SR), authoritative parenting (as demonstrated by high levels of Involvement, Strictness, and Autonomy Granting), and parent self-efficacy in four areas. Participants were 214 Australian high school students and their parents. There was a moderate…
