光照除了传统的视觉作用外, 还具有一定的非视觉效应, 包括调节昼夜节律、褪黑素分泌和警觉性等生理功能和行为表现。随着光照对生理节律影响研究的不断深入, 近来很多学者开始关注光照的警觉性作用。我们根据最新研究进展总结了:(1)警觉性的测量工具; (2)光照强度、时长、时间点、波长、色温等对光照警觉性作用的影响; (3)光照在治疗情绪障碍、调节生理节律、完善办公照明方面的应用; (4)提出了继续探讨光照警觉性作用的神经机制、优化参数特征和探讨混淆变量的研究方向。  相似文献

儿童在错误信念任务上的知识偏差   总被引:1,自引:0,他引:1  
采用3种任务考查儿童在错误信念(FB)推理中是否存在知识偏差。被试为60名3—5岁幼儿,结果表明,对于3岁及4岁儿童来说,FB任务是存在知识偏差的。知识偏差的大小与年龄呈负相关关系,3岁与4岁、4岁与5岁儿童的知识偏差的大小均有显著差异。  相似文献

Data from approximately 14,000 children in the Early Childhood Longitudinal Survey--Kindergarten Cohort were analyzed to examine the associations between children's immigrant status and their academic trajectories from kindergarten to 3rd grade, with particular attention to the effects of school environments. Growth curve modeling results indicated that most children of Latin American origin improved their reading and math scores faster than non-Hispanic White children, thus narrowing their initial score gap and sometimes even surpassing White children by 3rd grade. In contrast, although they maintained higher reading and math scores, children from East Asia and India showed decreasing scores over time, which tended to narrow their initial score advantage over non-Hispanic White children. School-level factors accounted partially for these differences. Particularly in terms of the academic trajectories, children of Latin American origin responded more to school-level factors than did children of Asian origin, who responded more to child and family background, with the exception of children from Vietnam, Thailand, Cambodia, and Laos, who responded more to school-level factors. Simulation results point to the importance of school resources for the academic trajectories of children of immigrants.  相似文献

Many traditional conjoint representations of binary preferences are additively decomposable, or additive for short. An important generalization arises under rank-dependence, when additivity is restricted to cones with a fixed ranking of components from best to worst (comonotonicity), leading to configural weighting, rank-dependent utility, and rank- and sign-dependent utility (prospect theory). This paper provides a general result showing how additive representations on an arbitrary collection of comonotonic cones can be combined into one overall representation that applies to the union of all cones considered. The result is applied to a new paradigm for decision under uncertainty developed by Duncan Luce and others, which allows for violations of basic rationality properties such as the coalescing of events and other framing conditions. Through our result, a complete preference foundation of a number of new models by Luce and others can be obtained. We also show how additive representations on different full product sets can be combined into a representation on the union of these different product sets.  相似文献

The National Board for Certified Counselors describes cybercounseling as the provision of some aspects of counseling through technology, via such applications as e‐mail, Web‐based information access, course registration, academic advising, and career guidance. The authors explore the characteristics of cybercounseling, describe its current use in the United States and South Korea, explore its advantages and disadvantages, and consider issues and concerns for college counselors.  相似文献

南北朝时期的佛教和道教发展十分兴盛,为了加强对宗教特别是佛道两教的管理,北魏最早设置僧官制度,任命沙门统和仙人博士官,建立了比较完备的宗教管理体制:昭玄系统和崇虚系统,分别管理佛教和道教.北魏的宗教管理体制首开政府宗教管理的先河,国家在政治、经济等诸多领域对宗教实行宏观管理,其先进的管理体制以及诸多管理原则和管理方式为后世所借鉴,产生了极为深远的影响.  相似文献

电子地图汉字大小辨认阈限和合理字间距   总被引:1,自引:1,他引:0  
本研究由三个实验组成,探讨电子地图中汉字呈现的辨认闽限和合理字间距(信息载负量)问题。实验一采用恒定刺激法测定电子地图中汉字的辨认闽限,结果显示,汉字复杂度和背景的复杂度都影响地图汉字识别,且不存在交互作用;宋体汉字的平均辨认阈限为7.0771’。实验二运用调整法测得在电子地图中宋体汉字的舒适阈限(能识别每个笔画的汉字辨认阈限)为16.6951’。实验三以视觉搜索方法研究字间距(体现在电子地图中单位面积字数)与搜索效率的关系,结果显示,每个汉字平均耗费的搜索时间随着字数增加而减少,说明字数越多,搜索效率越高。  相似文献

南昌大学江右哲学中心成立了"江西道教史"课题组,笔者有幸参加.因课题研究需要,本人于2007年8月1日至19日在江西各地考察道教宫观,先后考察了南昌青云谱、太平山佑圣宫、景德镇斗姥宫、贵溪鬼谷洞道院、萍乡横龙洞道院、武功山紫极宫和白鹤峰道观、会昌翠竹祠、赣州玉虚观、宁都翠微峰的金精洞碧虚宫、云台峰云台宫、普道岩紫微宫.其中太平山佑圣宫由于供奉有南宋道士章哲的肉身,是最引人注目的一处宫观.  相似文献

The present study examined the effect of spatial working memory load on the attentional cuing effect. It is well-known that spatial working memory and spatial attention functionally overlap or share a common resource. Given this functional overlapping, it is possible that spatial working memory would also interact with the attentional cuing effect. Considering the distinction between channel selection and channel enhancement by attention (Prinzmetal, McCool, & Park, 2005), we expected that the interaction between spatial working memory and the cuing effect would differ with attentional processing type. Two experiments conducted with the spatial cuing paradigm showed that the magnitude of the cuing effect as measured by reaction time, reflecting channel selection, was uninfluenced by spatial working memory load. In contrast, spatial working memory load reduced the cuing effect as measured by accuracy, reflecting channel enhancement. These results suggest that spatial working memory load impairs signal enhancement by attention and does not influence attentional orienting per se. The interaction between spatial working memory and visual perception is also discussed.  相似文献

目前我国医患关系紧张,医患纠纷解决机制是行政和司法为主的机制。有无更科学、合理、有效的解决办法。通过调查和理论分析,认为ADR应该成为我国解决医患纠纷的主要机制。协商是医生和患者最愿意采取的方式,仲裁和调解也是可行的,应该是我国医疗事故处理的有效补充。  相似文献
