Inhibitory response capacities of bilateral lower and upper extremities in children with developmental coordination disorder in endogenous and exogenous orienting modes

This study was designed to investigate separately the inhibitory response capacity and the lateralization effect in children with developmental coordination disorder (DCD) in the endogenous and exogenous modes of orienting attention. Children with DCD on the lower extremities (DCD-LEs), along with age-matched controls, completed four tasks that involved various applications of asynchronous stimuli to the feet or hands at various intervals. The results demonstrated that children with DCD-LEs had a significantly longer reaction time than the controls for all tasks, and were not alert to the appearance of the target. However, they displayed a deficit in volitional shifts of attention (endogenous mode), but not in automatic dislocation of attention (exogenous mode), whenever they performed the tasks with either their lower or their upper-limbs-even 6 months after the initial study. These findings confirm the deficit in the inhibitory response capacity in terms of volitional movement of attention by children with DCD. Additionally, the negative effect of lateralization on the bilateral extremities was not present in children with DCD-LEs. Significantly differences in response ability were detected only between the dominant and non-dominant sides of upper-limbs, but not between the lower-limbs, suggesting a future avenue for further experimentation on bilateral extremities.     

改革开放30年来道德教育发展特点概述

社会主义道德建设的过程也是道德教育发展的过程。30年来,随着改革开放的推进和中国社会的发展变化,道德教育的发展也呈现出与时代步伐共同演进的特点:逐渐形成从运动式的道德教育到形成规范的道德教育体系;坚持爱国主义教育为道德教育的主线;从社会道德教育到个人品德教育与社会道德教育相统一;道德教育从精英教育向公民教育转变;利用现代媒体和社会活动开展道德教育。     

Measuring subjective well-being: A comparison of China and the USA

In this article the structure of subjective well-being (SWB), the relationship between household income and SWB and mean differences in components of SWB in China and the USA are investigated. Both China and the USA were characterized in a three-factor model of SWB (life satisfaction, positive affect and negative affect). Household income was more strongly positively correlated with the three major components of SWB in China than in the USA. Lower levels of SWB were generally reported by participants in China than in the USA; however, there were mean differences in different regions of China.     

国外社会惰性的理论与相关研究概述

社会惰性是团队成员在从事趋向共同目标活动中出现的努力程度和平均贡献随着群体成员增加而减少的现象。该研究从社会惰性的概念、起源和发展、理论解释,影响因素及形成过程等几个方面对国外社会惰性的研究状况进行了述评,并指出存在的问题及今后研究的方向     

应激诱发复吸的动物模型及其神经生物学基础

复吸是药物成瘾的重要特征,应激是诱发复吸的因素之一。该文介绍了用于研究应激诱发复吸的动物恢复模型,阐述了涉及应激诱发复吸的神经生物学基础。大量研究结果表明,下丘脑外侧的终纹床核与杏仁核内的促肾上腺皮质激素释放因子和去甲肾上腺素是参与应激诱发复吸的重要神经递质。内侧前额叶皮层可能是介导应激、药物点燃及药物相关线索等各类因素诱发复吸的共同通路     

虚拟社会关系的心理学研究及展望

随着计算机及网络的普及,一种新型的、不同于传统“面对面（facetoface）”交往的社会关系——虚拟社会关系（virtualsocialrelationship）——已逐渐形成。该文从心理学角度对虚拟交往的动机、影响虚拟关系发展的因素及“虚拟”与“现实”的关系等进行了阐述,并在此基础上对未来虚拟社会关系的研究取向进行了展望,认为虚拟社会关系形成的心理基础、心理机制等将成为今后的研究热点     

决策过程中参照点效应研究述评

Kahneman和Tversky提出的“参照点效应”概念,对决策者的认知编码和信息整合方式做出了合理的解释,并对传统的理性决策理论提出了挑战。近年来,关于参照点效应的研究也一直受到众多学者的重视。文章系统阐述了参照点效应的相关概念和最新研究进展,并提出了参照点效应未来研究的4个趋势：日益重视多重参照点效应的研究、开始关注动态决策中的参照点变化机制、重视群体决策过程中的参照点效应研究、注重在现实决策任务中验证和发展参照点效应的相关理论     

返回抑制的容量研究：回顾与展望

返回抑制是指当注意返回到先前注意过的位置或客体时人们的反应变慢的一种抑制现象。自20世纪90年代中期以来,越来越多的返回抑制研究开始关注最多能在多少个线索化位置上观测到返回抑制效应,即返回抑制的容量问题。文章着重从序列线索化和同时线索化两方面介绍了当前返回抑制容量研究的主要成果,总结了该领域研究的特点及存在的问题,并对未来研究方向予以展望     

组织伦理气氛的理论与研究

学习不良儿童对情绪表达规则的认知特点

采用儿童对情绪表达规则的认知访谈故事,比较了学习不良儿童和一般儿童对情绪表达规则认知的发展特点。结果发现,学习不良儿童表情调节知识水平显著低于一般儿童,性别差异不显著,组别与年级交互作用不显著,表明两组儿童发展趋势类似,发展水平不同;学习不良儿童报告出较少的社会定向目标,自我保护目标得分与一般儿童差异不显著;学习不良儿童缺少根据不同人际关系类型灵活运用情绪表达规则的知识,而且较少把情绪表达规则的使用和目标联系起来
