Many studies have examined associations between children's theory of mind and social behavior with familiar peers, but to date none have examined how theory of mind might relate to behavior toward unfamiliar peers in a play setting. Forty-four 4-year-olds (21 girls, 23 boys) participated in standard theory-of-mind tasks and in a play session with 3 or 4 other children who were unfamiliar. Children were also tested on general vocabulary ability. No relations were found between theory of mind and social engagement. However, positive associations were found between theory of mind and time spent observing, but not interacting with, other children. Possible explanations of the links between theory of mind, temperament, and social interest are considered. 相似文献

Drawn from a larger study of Canadian children’s sense of self and media habits, this study explores the role of religiosity and/or spirituality within 535 children’s (281 girls, 254 boys; 5–13 years of age) self‐reported media preferences and habits over a three‐year period. Results indicate that the theme of spirituality and/or religiosity emerged most frequently within the context of after‐school activities, music listening habits and the reading habits of participants’ mothers. Aside from children in Grade 1 (five–six years), girls were more likely than boys to mention issues of spirituality and religiosity, particularly during preadolescence (10–13 years). Younger children reported more issues of spirituality than older children. Results are discussed in terms of educational implications for critical media literacy. 相似文献

验证收缩骨骼肌细胞葡萄糖转运蛋白4（GLUT4）基因的表达在转录水平上是否受转录抑制子Ⅱ型HDAC5蛋白（简写为HDAC5）的调节。研究运用运动模拟信号5-氨基-4-甲酰胺咪唑核糖核苷酸（AICAR）和HDACs抑制剂SCRIPTAID孵育骨骼肌细胞。用蛋白印迹技术测定HDAC5蛋白表达,定量RT-PCR法检测GLUT4 mRNA表达。与无AICAR的对照组相比,AICAR组骨骼肌细胞内HDAC5减少了29%,并伴随有124% GLUT4 mRNA的增加,但肌细胞内HDAC5的蛋白总量无变化;使用HDACs抑制剂SCRIPTAID刺激骨骼肌细胞能够明显增加核心组蛋白乙酰化水平和上调GLUT4基因的表达。这些结果提示,通过AICAR和SCRIPTAID分别减少或抑制核HDAC5均能上调骨骼肌细胞GLUT4基因的转录,HDAC5可能在转录水平上对肌肉收缩引起的GLUT4基因的表达起着重要的调节作用。 相似文献
