Athletes frequently have to adapt their skills to fast changes of play, often requiring the flexible execution of a particular movement skill with either hand. To assess the influence of sport-specific expertise and extensive sport training on human laterality, a video analysis of regular basketball games was performed for professional, semi-professional, and amateur players to investigate how non-dominant hand use and proficiency change with increasing expertise. Our results showed that the right-hand (i.e. dominant hand) bias in basketball players is reduced with increasing expertise (i.e., competitive level). Accordingly, we found that professional players use their non-dominant hand more often and with greater success than semi-professional and amateur players. This was true for most of the basketball-specific skills. Based on these results, we assume that increasing amounts of bilateral practice can lead to a shift in task-specific manual preference towards a higher use of both hands in competition, as well as to a higher proficiency for non-dominant hand actions in particular. From an applied perspective, the more frequent use and higher proficiency of the non-dominant hand in professional basketball players, compared with amateurs, suggests that the context-specific and skilled use of the non-dominant hand is crucial for successful play at higher competitive levels in the sport of basketball. 相似文献

This article examines the impact of professional education on students' dedication to and identification with a profession. The premise is that professional education is not only about knowledge acquisition and reasoning but also about attitudes and aspirations. In fostering dedication and identification, students' experiences of relevance seem to be important. The concept of coherence seen as an expression of relevance is introduced and measured by four kinds of interactions: Theory–practice interaction, teacher–student interaction, peer interaction and supervisor–student interaction. Analysis indicates that coherence, particularly as theory–practice interaction, peer interaction and supervisor–student interaction, has a significant impact on dedication to and identification with a profession. Longitudinal survey data – collected from students in colleges for teaching, nursing and social work – are analysed. 相似文献

The aim of this study was to explore parents’ perspectives on the role of school factors in school refusal (SR). Semi-structured interviews were conducted with 17 parents who had experienced SR with their own child. They identified several school factors related to SR. Some of these findings suggest that students who are prone to SR need more predictability and more teachers’ support than they sometimes get in school. Their need for predictability seems to occur particularly during less structured activities and during transitions in school. Findings also imply that disruptive behavior among classmates and harsh management from teachers affects perceived predictability and support for SR-prone students. All parents expressed concern about bullying, and roughly a third of them reported that their child had been a victim of bullying. Insufficient adaptation of schoolwork was also mentioned relatively frequently. Parents emphasized that adaptation of schoolwork needs to be done in close cooperation with the student and parents to avoid negative differentiation from classmates or stigma. Finally, several parents commented that teachers and schools need more knowledge about SR and felt that schools needed a more coordinated approach to supporting students who are at risk of SR. 相似文献
