黄颖峰  程涛 《体育科研》2008,29(4):62-66

本实验利用人为强化本体感受反馈的原理探讨一种新的加速运动技能获得的方法？实验参加青在电脑屏幕前用鼠标追踪电脑屏幕上一个移动的光点，移动光点按预定的程序作曲线运动另一子程序按每秒一百次的频率自动扫描移动光点与追踪鼠标点之间的距离，每轮追踪结束后自动计算出该轮扫描误差的标准差，移动光点与追踪鼠标点之间的距离越小，追踪误差越小随着练习次数及练习天数的增加，追踪误差会越来越小。我们发现，在保证运动连续性的条件下最大限度地增强与运动相关的主动肌、对抗肌、协同肌及支持肌自身紧张度可以加速运动技能的获得。  相似文献   

视角、引语形式、叙述者的隐退与布里尔小姐的幻灭--《布里尔小姐》的叙事策略分析     

杨云红 《玉溪师范学院学报》2004,20(4):56-59

《布里尔小姐》通过选择人物有限视角叙事 ,使用自由间接引语表现主人公的“顿悟” ,让叙述者从叙述中退出 ,使小说充满人物的主体意识 ,并在关键时刻使用直接引语否定“顿悟”形成“幻灭”。自由间接引语与直接引语在形式和内容上的强烈对比 ,构成了布里尔小姐的主观认识与客观现实的冲突 ,构成了布里尔小姐话语“无声”与他人话语“响亮”之间的反差。  相似文献

Using iPad tablets for self‐modeling with preschoolers: Videos versus photos          下载免费PDF全文

Dacia M. McCoy  Julie Q. Morrison  Dave W. Barnett  Hilary D. Kalra  Lauren K. Donovan 《Psychology in the schools》2017,54(8):821-836

As technology becomes more accessible and acceptable in the preschool setting, teachers need effective strategies of incorporating it to address challenging behaviors. A nonconcurrent delayed multiple baseline design in combination with an alternating treatment design was utilized to investigate the effects of using iPad tablets to display video self‐modeling and activity photos for three preschoolers during circle time. During baseline, all three children demonstrated low levels of engagement and high levels of off‐task behavior compared to peers. The intervention phase consisted of alternating between showing the child the self‐video and photos prior to circle time. A child preference phase was conducted whereby each child self‐selected the video or photo prior to circle time. For all three children both videos and photos led to increased engagement and decreased off‐task behaviors. During the child preference phase, all three children selected the video most frequently. Social validity data demonstrated teacher and child preference for the video self‐modeling condition.  相似文献   

Using 21st century video prompting technology to facilitate the independence of individuals with intellectual and developmental disabilities          下载免费PDF全文

Barriers in acquiring, maintaining, and generalizing daily living skills are factors that contribute to discrepancies in independent living outcomes among transition age youth and young adults with intellectual and developmental disabilities (IDD). Acquisition and generalization of daily living skills empowers transition age youth and young adults with disabilities to meet their own needs with minimal reliance on others. Infusing the use of technology as a self‐prompting device facilitates the acquisition of tasks that may not be otherwise attainable. In this study, self‐directed video prompting on an iPad with the My Pictures Talk application was used to help young adults with IDD in a postsecondary program acquire daily living skills in a single subject, multiple probe across subjects design. The effects of the intervention on generalization to tasks that were one, two, and three components different were also assessed. Results demonstrated a functional relationship between the introduction of the intervention and improvement in skill performance.  相似文献

Japanese Conceptions of Privacy: An Intercultural Perspective     

Makoto?NakadaEmail author  Takanori?Tamura 《Ethics and Information Technology》2005,7(1):27-36

This paper deals with intercultural aspects of privacy, particularly with regard to important differences between Japanese and the Western views. This paper is based on our discussions with Rafael Capurro – a dialogue now represented by two separate but closely interrelated articles. The companion paper is broadly focused on the cultural and historical backgrounds of the concepts of privacy and individualism in “Western” worlds; our main theme focuses on different concepts of privacy in Japan and their sources in related aspects of Japanese culture. The interrelationship between our two papers is apparent in our taking up identical or similar topics in each paper. Reading our two papers in conjunction with each other will bring about deeper and broader insights into the diverse values and worldviews of Japan and Western cultures that underlie concepts of privacy that at a surface level appear to be similar  相似文献   

摩尔定律的思想潜力和极限   总被引：1，自引：0，他引：1  

马群刚  杨建飞  李跃进  杨银堂 《中国软科学》2002,(9):70-76

集成电路是电子信息产业的核心,在其发展过程中,摩尔定律起到了预言和导向的作用,所以,摩尔定律的思想潜力和应用极限不仅关系到信息产业的前景,也关系到目前人类技术思想的前沿趋向和社会经济形态的进化与转型。本文结合科学方法论关于在两极中保持张力的准则,分别阐述并预测了摩尔定律在电脑、语言辨识、光纤设备和光器件中的应用以及促使摩尔定律达到极限的几个技术思想方面的问题。  相似文献

多元文化背景下的自我价值与身份建构——论任碧莲的《典型的美国佬》     

魏琴 《青海师范大学学报(哲学社会科学版)》2011,33(6):98-101

当代华裔女作家任璧莲的成名作《典型的美国佬》被认为是新一代华裔美国文学的代表作。小说着意刻画了多元文化背景下人物的身份问题并对其进行了新的诠释。本文主要是通过分析主人公自我的体现,即对中国传统价值的认同和对美国梦的不同理解与追求方式,来探讨自我与美国梦对人物流动身份的影响,同时关注了作品开放式结局的寓意所在。  相似文献
