People can make pointing gestures and tracing actions with the index finger with little or no conscious effort. From the perspective of cognitive load theory, such “biologically primary” gestures and actions might help people learn “biologically secondary” concepts and skills requiring extended cognitive effort, such as reading, science, or mathematics. Studies on tracing or tracing and pointing have yielded mixed findings regarding hypothesized effects on intrinsic and extraneous cognitive load. The present study investigated whether computer-based instructions to trace elements of worked examples on angle relationships would affect school students' (N = 106) self-reports of intrinsic and extraneous cognitive load, as well as problem-solving transfer test performance. The tracing effect on transfer posttests seen in prior studies was replicated, but cognitive load hypotheses were not supported. Implications for educational practice and future research are discussed. 相似文献

The present study aimed to investigate the prevalence of fatigue and determine factors associated with fatigue in female medical personnel. Based on a cross-sectional study, a total of 1608 female medical personnel at 54 hospitals in Zhuhai, China were recruited by a multistage stratified cluster sampling method. The Symptoms Checklist-90-Revised and Chalder Fatigue Scale were used to assess psychiatric symptoms and fatigue, respectively. Data regarding demographic, health, and work related variables were also collected. Multivariate logistic regression model was constructed to determine the influencing factors of fatigue. Approximately 83% of participants had experienced fatigue in the past week. The risk of fatigue was higher in aged 30–39 years old than older or younger participants; Longer sleeping time predicted a lower prevalence of fatigue (OR = .35), while tense physician-patient relationship predicted a higher prevalence of fatigue (OR = 1.77). Depression (OR = 1.76) and anxiety (OR = 1.96) were found related to fatigue. Additionally, fatigue was associated with marital status, occupation, health related factors (exercise, regular diet, and health status), and work related factors (hospital rank and turnover intention). These study findings might facilitate development and implementation of targeted interventions and preventive measures. 相似文献

This article challenges the pessimistic view that empathy and other fellow feelings are biased and erratic motivation for morality. By discussing Mencius’ account on how to develop empathy from its biased and erratic beginnings, I argue that empathy can be extended to less common objects, such as non-kin, the faraway, the unfamiliar, and the abstract. The extension facilitated by empathy in turn enhances one’s moral cognition toward the sufferings of less common objects; the extension also helps to include less common objects into one’s circle of care. I respond to critics of empathy such as Prinz by highlighting the dynamic cultivational process of empathy that they overlook, and further point out that empathy can be cultivated so as to provide a remedy for the biases that no emotion is immune to. This article contributes to the ongoing discussion on moral cultivation in the Chinese philosophy community and the dispute over empathy’s role in morality in contemporary ethics. 相似文献

私人复制著作权问题是随着复制技术进步而带来的.在数字和网络技术普及之前,国际上对私人复制问题的讨论主要围绕影印复制、家庭录制等问题展开.随着数字和网络技术的发展,则关注点集中于数字和网络环境下私人复制问题.在国际立法中,"三步检验法"成为规制和衡量包括私人复制在内的复制行为的重要立法成果.私人复制问题反映了复制权保护、限制与技术变革的互动关系.为因应复制技术变革,一些国家著作权立法逐渐完善了私人复制制度.我国著作权法修改在即,如何完善相应规定值得深入研究. 相似文献
