Chinese kindergartners’ automatic processing of numerical magnitude in Stroop-like tasks 总被引:2,自引:0,他引:2
Using Stroop-like tasks, this study examined whether Chinese kindergartners showed automatic processing of numerical magnitude. A total of 36 children (mean age 5 5 years 10 months) were asked to perform physical size comparison (i.e., “Which of two numbers is bigger in physical size?”) and numerical magnitude tasks (i.e., “Which of two numbers is bigger in numerical magnitude?”) on 216 number pairs. These number pairs varied in levels of congruence between numerical magnitude and physical size (for Stroop effect) and numerical distance (for distance effect). On the basis of analyses of response time and error rates, we found that Chinese kindergartners showed automatic processing of numerical magnitude. These results are significantly different from previous studies’ findings about the onset age (ranging from around the end of first grade to third grade) for automatic processing of numerical magnitude. 相似文献

The authors examined conditions under which teams' educational specialization heterogeneity was positively related to team creativity. Using a sample of 75 research and development teams, the authors theorized and found that transformational leadership and educational specialization heterogeneity interacted to affect team creativity in such a way that when transformational leadership was high, teams with greater educational specialization heterogeneity exhibited greater team creativity. In addition, teams' creative efficacy mediated this moderated relationship among educational specialization heterogeneity, transformational leadership, and team creativity. The authors discuss the implications of these results for research and practice. 相似文献

If it goes up, must it come down? Chronic stress and the hypothalamic-pituitary-adrenocortical axis in humans 总被引:3,自引:0,他引:3
The notion that chronic stress fosters disease by activating the hypothalamic-pituitary-adrenocortical (HPA) axis is featured prominently in many theories. The research linking chronic stress and HPA function is contradictory, however, with some studies reporting increased activation, and others reporting the opposite. This meta-analysis showed that much of the variability is attributable to stressor and person features. Timing is an especially critical element, as hormonal activity is elevated at stressor onset but reduces as time passes. Stressors that threaten physical integrity, involve trauma, and are uncontrollable elicit a high, flat diurnal profile of cortisol secretion. Finally, HPA activity is shaped by a person's response to the situation; it increases with subjective distress but is lower in persons with posttraumatic stress disorder. 相似文献

Adult visual experience promotes recovery of primary visual cortex from long-term monocular deprivation 下载免费PDF全文
Prolonged visual deprivation from early childhood to maturity is believed to cause permanent visual impairment. However, there have been case reports of substantial improvement of binocular vision in human adults following lifelong visual impairment or deprivation. These observations, together with recent findings of adult ocular dominance plasticity in rodents, led us to re-examine whether adult primary visual cortex (V1) is capable of any recovery following long-term monocular deprivation starting in development. Using mice as a model, we find that monocular deprivation from early development to mature ages (well past the critical period) severely impaired binocular vision by reducing the amplitude of responses elicited by stimulation of the deprived eye. Surprisingly, we find little effect on nondeprived eye responses. Restoration of binocular vision in mature adults yields modest but significant improvement of visual responses in V1. Remarkably, we find that when binocular vision is followed by occlusion of the nondeprived eye, visual responses in V1 recover almost fully, as measured by visual evoked potential amplitude, spatial frequency threshold, and single-unit activity. We conclude that adult V1 can recover from long-term deprivation when provided with an optimal regimen of visual experience. 相似文献

中国社会现代化进程和城市现代化水平 与中国人群体人格变化模式 总被引:2,自引:1,他引:1
再利用本土化的人格工具CPAI,对中国社会现代化发展时间进程和城市现代化水平差异与中国人群体人格特征模式之间的关系进行了探讨。研究结果表明,中国人的群体人格特征正在随着社会发展而成现出相应的变化,表现为更为多元化、个性张扬、人际关系的束缚在减弱。当然,现代化进程的时间和空间特征对人格变化的影响可能存在差异性。因此,在研究社会发展与人格间关系时,应该同时关注社会变迁的时间与空间两个维度。研究显示,随着中国社会的发展,具有开放性、多样性人格特征的新一代中国人正在形成过程中,他们反过来也会对中国的现代化进程产生影响 相似文献
