Creativity: A social approach     

Arthur Cropley 《Roeper Review》2013,35(3):125-130

Early thinking in the modern era often regarded creativity as a somewhat asocial means of individual expression, self‐realization, and self‐fulfillment. However, it also is a socially influenced phenomenon that serves society. A social approach offers the opportunity of distinguishing between large and small amounts of novelty, as well as between “orthodox” and “radical” novelty. Disciplines, teachers, and students differ from one another on these dimensions. This explains some differences among teachers in the way they see creativity and creative students. The social approach also emphasizes the importance of groups, role models and mentors, and classroom climate, all of which teachers can influence. A social analysis suggests guidelines for instruction and assessment that differ from those derived from cognitive or personal approaches.  相似文献

Physical activity and executive control: implications for increased cognitive health during older adulthood     

Hillman CH  Belopolsky AV  Snook EM  Kramer AF  McAuley E 《Research quarterly for exercise and sport》2004,75(2):176-185

Electrocortical and behavioral responses of low, moderate, and high physically active older adults were compared with a younger control group on neutral and incompatible conditions of a flankers task. Compared to younger adults, high and moderate active older adults exhibited increased event-related potentials component P3 amplitude for the incompatible condition at the frontal electrode site. For the neutral condition, only low active older adults exhibited decreased amplitude at the central-parietal site, compared to younger adults. P3 latency revealed the longest latencies for low active older adults, followed by moderate active, high active, and younger adults, respectively. Reaction time (RT) data revealed that younger adults exhibited faster RT compared to all three older groups. Results suggest that physical activity may improve executive control function in older adults by affecting the distribution of P3 amplitude, which has been related to memory and attentional processes, and by decreasing P3 latency, which relates to the speed of cognitive processing.  相似文献   

Estimation of thigh muscle and adipose tissue volume using magnetic resonance imaging and anthropometry     

Tothill P  Stewart AD 《Journal of sports sciences》2002,20(7):563-576

Thigh muscle volume is a useful determinant of functional fitness. However, anthropometric prediction of muscle content is influenced by the variability of adipose tissue accumulation. The aims of this study were to predict thigh muscle and adipose tissue volumes from anthropometry and to assess the validity of the method by examining the various components of the measurements and the assumptions involved. The 19 participants (9 men, 10 women; age 23-49 years) varied in adiposity. They all underwent magnetic resonance imaging (MRI) of the upper leg and the eight men and two women with the lowest adiposity underwent detailed anthropometry involving girths and skinfolds. Using MRI as the reference method, muscle volume was predictedfrom anthropometry using a circular concentric model, and the assumptions inherent in the method were tested further using the MRI data alone. Muscle volume was best predicted by anthropometry in the 10 leanest participants using a five-slice truncated cone model that overestimated the mean MRI value by 30% (R2 = 0.95; standard error of estimate = 288 cm3; P < 0.001). A single skinfold plus girth measurement at the mid-thigh almost matched its predictive ability, but with an increased bias. Measurements of leg circumference by means of the two techniques agreed well. The assumption of a circular cross-section was valid. In contrast, the agreement between skinfold thickness measured by caliper and superficial adipose tissue thickness by MRI was poor, contributing to the scatter of fat and lean area comparisons. An anterior skinfold thickness measurement underestimated the area of superficial adipose tissue at that level, particularly at the most proximal and distal sites. Although these limitations increase the uncertainties of muscle volume determination by anthropometry, they do not prevent its valid prediction in leaner individuals. The prediction of superficial adipose tissue was poorer.  相似文献
