Multidimensional models of giftedness specify individual and environmental moderators or catalysts that help transform potential into achievement. However, these models do not state whether the importance of the ‘individual boxes’ and the ‘environmental boxes’ changes during this process. The present study examines whether, during the early stages of talent development, the ‘environmental boxes’ play a more important role than the ‘individual boxes.’ To answer this question, we analyzed individual moderators and environmental moderators of achievement for fourth-grade primary-school students (N?=?976). A cluster analysis that included intelligence, achievement, and two individual moderators (motivation and learning behavior) revealed three groups of students, two of which are of particular interest, as they both displayed high intelligence and achievement but differed in their motivation and learning behavior. Questionnaire data on family environment (filled out by parents, N?=?682) and school environment (filled out by teachers, N?=?47) supported the assumption that among young students an inauspicious set of individual moderators, in this case maladaptive motivation and learning behavior, can be compensated by a sufficiently propitious set of environmental moderators, in this case parents’ and teachers’ learning support, cultural capital within the family, and teachers’ commitment to support their students’ learning. 相似文献

Contrasting Social and Cognitive Accounts on Overimitation: The Role of Causal Transparency and Prior Experiences

Three experiments (N = 100) examine the influence of causal information on overimitation. In Experiment 1, a transparent reward location reveals that the reward is unaffected by nonfunctional actions. When 5‐year‐olds observe an inefficient and subsequently an efficient strategy to retrieve a reward, they show overimitation in both phases—even though the reward is visible. In Experiment 2, children observe first the efficient then the inefficient strategy. The latter is always demonstrated communicatively, whereas the efficient strategy is presented communicatively (2a) or noncommunicatively (2b). Regardless of whether the efficient strategy is emphasized through communication or not, most children do not switch from the efficient to the inefficient strategy. Depending on the situation, children base their behavior on social motivations or causal information. 相似文献

Juvenile obesity is increasing worldwide. Preventive strategies are warranted. The school-based Children's Health Interventional Trial (the CHILT Project) combines health education and physical activity for children. The effect on obesity and physical performance was studied after four years in 12 primary schools compared with five control schools. Anthropometric data were recorded. Physical performance was measured by a coordination test for children (balancing backwards, one-legged obstacle jumping, lateral jumping, sideways movements) and a 6-min run (endurance). No difference in the prevalence and incidence of overweight and obesity was found between the intervention and control schools before and after the intervention. Remission of overweight was higher in the intervention schools (23.2 vs. 19.2%), but not significant. An increase in coordination related to lateral jumping and balancing backwards was apparent in the intervention schools (30.6, s = 10.8 vs. 26.1, s = 10.8, P = 0.005; 21.8, s = 11.8 vs. 19.4, s = 11.7, P = 0.007), and the increase in endurance performance tended to be higher in intervention schools (100.8, s = 122.7 vs. 92.8, s = 126.0, P = 0.055), adjusted for age, sex, baseline test result, and body mass index at final examination. Therefore, preventive intervention in primary school offers the possibility to improve physical performance in children. The prevalence and incidence of obesity were not affected. 相似文献

Purpose: Visual attention is essential in many areas ranging from everyday life situations to the workplace. Different circumstances such as driving in traffic or participating in sports require immediate adaptation to constantly changing situations and frequently the conscious perception of 2 objects or scenes at the same time. Method: The attention window task, a measure of attentional breadth, in which people must attend to 2 equally attention-demanding stimuli simultaneously, was introduced. This article provides a narrative review of studies using this task and outlines different factors that might influence the attention window. Results: Differences in the spatial distribution of attention result, for example, from effects of age or physical activities as well as from emotional processes and those affected by current motivation, while gender does not have any influence. The window is represented as an ellipse with greater attentional breadth along the horizontal axis than the vertical axis, and it is about 5 to 6 times smaller than the human visual field. Conclusion: Not only everyday occurrences but also situations in sport games—for example, having an overview of the opponent, teammates, and the ball—require the ability to pay visual attention to 2 peripheral objects and continuously changing situations. Therefore, the application or avoidance of different strategies and factors is discussed to improve and adjust behavior in those situations. 相似文献
