Development of skill in young soccer players relies on progressive improvement in different professionally important sensorimotor cognitive abilities. Development of seven leading abilities was based on the results of 23 tests provided for experimental and control groups. 600 elite young soccer players of both sexes, ages 11 to 19 years, were assessed over a period of 4 years. Experimental groups were given different exercises to aid development of selected abilities. At the end of the monitoring period, the experimental groups demonstrated a significant improvement in contrast to the control groups, and the greatest improvements in different test performances were observed in the 11- to 13-year-olds. The test-retest ata show the testing process to be reliable. The study provides standard pedagogical models and data for trainers, coaches, and researchers working with young soccer players. Future research on talent identification and selection should adopt amultidimensional approach. 相似文献

The current study tested the stress-reactivity extension of response styles theory of depression (Nolen-Hoeksema Journal of
Abnormal Psychology 100:569–582, 1991) in a sample of high-risk children and early adolescents from a vulnerability-stress perspective using a multi-wave longitudinal
design. In addition, we examined whether obtained results varied as a function of either age or sex. During an initial assessment,
56 high-risk children (offspring of depressed parents; ages 7–14) completed measures assessing rumination and depressive symptoms.
Children were subsequently given a handheld personal computer which signalled them to complete measures assessing depressive
symptoms and negative events at six randomly selected times over an 8-week follow-up interval. In line with hypotheses, higher
levels of rumination were associated with prospective elevations in depressive symptoms following the occurrence of negative
events. Sex, but not age, moderated this association. Rumination was more strongly associated with elevations in depressive
symptoms following the occurrence of negative events in girls than in boys. 相似文献

Sex differences in the latent general and broad cognitive abilities underlying the Differential Ability Scales, Second Edition were investigated for children and youth ages 5 through 17. Multi-group mean and covariance structural equation modeling was used to investigate sex differences in latent cognitive abilities as well as changes in these differences across age. Most broad abilities showed mean differences across the sexes, and all such differences varied across ages. Girls showed an advantage on the processing speed (Gs) first-order residual factor. Girls also showed advantages at some ages on free-recall memory, a narrow ability of long term retrieval (Glr). Boys showed a developmentally-related advantage on a visual-spatial ability (Gv) first-order residual factor, depending on age. Younger girls showed an advantage on short-term memory (Gsm). No statistically significant sex differences were shown on the latent comprehension-knowledge (Gc) factor, or on a second-order, latent g factor. Boys showed larger variances for several broad abilities, some substantial, but those differences were not statistically significant. 相似文献

Extant data collected through the Experience Sampling Method were analyzed to describe adolescents' subjective experiences of homework. Analyses explored age and gender differences in the time adolescents spend doing homework, and the situational variations (location and companions) in adolescents' reported concentration, effort, interest, positive affect and stress while doing homework. Regarding age differences, middle school students reported more positive experiences when homework was done with companions and in locations other than home, whereas high school students reported more positive experiences when homework was done alone and at home. Regarding gender differences, girls, regardless of age, reported greater stress than boys when doing homework alone, and lower stress when doing homework with friends. High school girls reported lower interest than middle school boys when doing homework alone. Findings provide an understanding of age and gender differences in adolescents' perceptions of homework, which might help educators and parents structure engaging homework environments. 相似文献

At times, consumers are motivated to reduce the influence of a product recommendation on their judgments. Based on previous research, it is unclear whether this correction process will increase or decrease consumers' confidence in their judgments. We find that source credibility moderates the effect of correction on confidence: correction decreases confidence when a product recommendation comes from a high credibility source but increases confidence when the same message comes from a low credibility source. As a result, correction increases the effectiveness of recommendations from low credibility sources on purchase intentions. Notably, this “confidence via correction” effect is further moderated by elaboration, such that the effect is attenuated for high elaboration consumers. Our results have implications for understanding consumers' reactions to persuasive messages and for both marketing practitioners and consumer protection agencies using correction cues to influence message persuasiveness. 相似文献

Great apes can perceive images as representative of corresponding real-life objects. Coupled with the potential advantages of identifying specific members of one’s species and mounting evidence for individual recognition in other non-humans, it seems likely that great apes would have the ability to identify conspecifics in photographs. The ability of four orangutans and a gorilla to match images of individuals of their own and a closely related but unfamiliar species was examined here for the first time. First, the subjects matched photographs of familiar conspecifics taken at various time points in a delayed matching-to-sample procedure (Experiment 1). Second, they matched different photographs of unfamiliar individuals of a different species (Experiment 2) at above chance levels. These results suggest that the subjects matched photographs by matching physical features, not necessarily by recognizing the identity of the individuals depicted. However, they also quickly learned to select photographs of familiar individuals when these photographs were paired with photographs of unfamiliar individuals of their own species (Experiment 3), and three subjects showed transfer to novel images of familiar and unfamiliar individuals. Thus, the findings support the idea that subjects attended to physical features to identify individuals that they could categorize on the basis of familiarity. 相似文献
