Rapid automatized naming (RAN) is associated with children's arithmetic performance, which is multifactorial by nature and consists of arithmetic fluency, arithmetic procedure, and word problems. Yet, it is unclear whether RAN can predict all key aspects of arithmetic skills independently and what cognitive mechanisms may explain this relation. Using a sample of Chinese primary school students (N = 170), results showed that while RAN was associated with all key aspects of arithmetic skills, the relations of RAN–arithmetic procedure and RAN–word problems may be dependent on that of RAN–arithmetic fluency. Supporting the processing speed hypothesis, results further suggested that processing speed may underlie the relation between RAN and arithmetic performance. Findings made unique contribution to understanding the effect of RAN on arithmetic performance and cognitive mechanisms that may underpin this association in the context of Chinese culture. 相似文献

ABSTRACTThis study identified key somatic and demographic characteristics that benefit all swimmers and, at the same time, identified further characteristics that benefit only specific swimming strokes. Three hundred sixty-three competitive-level swimmers (male [n = 202]; female [n = 161]) participated in the study. We adopted a multiplicative, allometric regression model to identify the key characteristics associated with 100 m swimming speeds (controlling for age). The model was refined using backward elimination. Characteristics that benefited some but not all strokes were identified by introducing stroke-by-predictor variable interactions. The regression analysis revealed 7 “common” characteristics that benefited all swimmers suggesting that all swimmers benefit from having less body fat, broad shoulders and hips, a greater arm span (but shorter lower arms) and greater forearm girths with smaller relaxed arm girths. The 4 stroke-specific characteristics reveal that backstroke swimmers benefit from longer backs, a finding that can be likened to boats with longer hulls also travel faster through the water. Other stroke-by-predictor variable interactions (taken together) identified that butterfly swimmers are characterized by greater muscularity in the lower legs. These results highlight the importance of considering somatic and demographic characteristics of young swimmers for talent identification purposes (i.e., to ensure that swimmers realize their most appropriate strokes). 相似文献

The contribution of employment in high technology industry to future employment growth in the US economy is estimated to be small. Much high technology employment is not professional work at all, but routine labour, and much of that performed by minority groups with few career opportunities. Most new jobs will occur in occupations requiring no more than secondary education. High technology may generate employment in other areas, but often low grade work performed in the “homework economy”. Appropriate education for employment in high technology industry and in computer-related fields is not necessarily specialised and technical; high-quality general education is probably more important. Instrumental education, ignorant of the demands of high technology, and of the demands a modern economy makes upon high technology, is likely to be counter-productive. Commercial and technical success requires a combination of cultural learning and technical skill. 相似文献

试验选取三类不同熟期的春小麦品种(品系),在同一时间倒伏后,分期对比测定各品种(品系)倒伏后不同发育阶段的籽粒鲜重、干重,比较分析品种(品系)倒伏与未倒伏籽粒的灌浆特性及干物质积累变化规律。结果表明:倒伏对不同品种(品系)籽粒干物质积累动态变化的差异显著性影响不同,对同一品种(品系)的最大灌浆速率及到达最大灌浆速率的时间均存在着影响,最终对籽粒产量存在着不同程度的影响。 相似文献
