The Structure of Creativity in Primary Education: An Empirical Confirmation of the Amusement Park Theory

In this study, we explored the structure of pupils’ creativity in primary education following the Amusement Park Theory, by investigating undiscovered linkages between the domains of writing, mathematics, and drawing. More specifically, we examined: (a) whether some domains and general thematic areas are more closely related to each other than to others, (b) whether literacy and mathematical ability are specific underlying traits of creativity in writing and mathematics, respectively, and (c) whether intelligence and divergent thinking are related to creativity in all domains. The sample consisted of 331 Dutch 4th grade pupils. For each research question, a model was analyzed using structural equation modeling. We found creativity in mathematics and creativity in writing to be most similar, followed by creativity in mathematics and creativity in drawing, with creativity in writing and creativity in drawing being least similar. Additionally, we found evidence for several underlying traits (i.e., literacy ability and mathematical ability) and initial requirements of creativity (i.e., intelligence and divergent thinking), none of which were important for creativity in only one domain, and of which only intelligence was important for creativity in all domains. Herewith, our study provides insights regarding the complexity of the structure of creativity in primary education.     

The Effects of Success and Failure on Children's Use of Defense Mechanisms

ABSTRACT The effects of moderate stress on the use of defense mechanisms by 64 second- and sixth-graders were determined The use of denial, projection, and identification was assessed from stones told to the Thematic Apperception Test (TAT) prior to, and subsequent to, an experimentally controlled experience of success or failure Subjects who experienced failure were more likely to use the lower level defenses of denial and projection, while the experience of success was followed by greater use of identification The results also were consistent with previous studies in demonstrating age and sex differences in the use of defense mechanisms     

Processing resources and age differences in working memory

This study investigated the performance of young and old subjects on a modified version of the working memory task developed by Baddeley and Hitch (1974). Subjects were required to verify a set of sentences of varying complexity while they repeated aloud zero, two, or four words. The older subjects took longer to verify the sentences, especially when the sentences were grammatically complex, but the effect of concurrent memory load on verification latency was the same in both groups. These results cast doubt on the notion that there is an age-related decline in one general pool of processing resources. They also suggest that older people have greater difficulty with the active processing aspects, rather than with the passive holding aspects, of working memory tasks.     

立体视觉的心理物理和VEP比较研究

心理物理试验是研究立体视觉的主要方法。70年代VEP开始用于体视研究,并取得许多结果。由于VEP信号复杂,这些结果不能令人满意。本文使用心理物理试验和VEP对比方法对体视加以研究。我们的结果是:VEP波形中第一个正峰与刺激图形的亮度有关;N_2峰和P_3峰的潜伏期对判断体视存在与否有重要价值;本试验确定N_2峰潜伏期在体视存在时约为240ms—280ms,无体视存在时约为290ms—310ms;P_3峰潜伏期在体视存在时约为280ms—310ms,无体视存在时约为340ms—360ms;体视存在时的VEP与无体视存在时的VEP的互相关系数小于0.1;有体视的VEP其功率谱密度在8Hz附近有一峰;心理物理试验中使用强制选择得到的结果从VEP波形比较中可以确认是可靠的;有体视的VEP其N_2和P_3的潜伏期随视差变化呈现规律性改变。     

Contributions of a supportive work environment to parents' well-being and orientation to work

Examined the joint and unique contributions of informal social support in the workplace and formal, family-responsive benefits and policies provided by employers to the job-related attitudes and personal well-being of employed parents with a young child. Eighty married men, 169 married women, and 72 single women with a preschool child completed a survey concerning social support from co-workers and supervisor, utilization of family-responsive benefits and policies, readiness to leave the employer for additional benefits, job satisfaction, organizational commitment, role strain, and health symptoms. Among the findings: (a) Fathers and mothers expressed equal levels of job satisfaction and organizational commitment, but mothers reported more role strain and health symptoms; (b) nearly 48% of married women's organizational commitment was accounted for by measures of support in the workplace; (c) informal social support at work was significantly more important to men's well-being than that of women; and (d) formal, family-responsive policies appeared more consequential for the prediction of women's role strain, perhaps because of women's greater responsibility for adjusting work life to meet the demands of family roles.     

The division of labor within the home: Have gender roles changed?

The purpose of this paper was to examine more recent time-use data regarding the division of labor in the home and compare those findings with that of previously reported data. A 1981 national sample of married Canadian men and women's time use was examined. Generalized least squares regression was employed to examine and predict time use by married men and women as a function of spouse's labor force status, number of children, age of youngest child, and day of the week data were collected. As compared to previous studies, results indicate that over time married women have reduced the amount of time spent in meal preparation while increasing time spent with children. Men increased the amount of time spent in food preparation and child care, although their participation appeared limited primarily to weekend days and invariant to wife's labor force participation.
