心智游移是一种常见的非自主内源性意识体验,在人类意识系统中占重要地位,近年在意识及神经科学研究领域引起广泛关注。心智游移类似现象的测量主要从白日梦、自发思维、认知失误及心神不宁等现象入手,研究其频率、内容结构及功能等方面的特征。总结国外研究结果,分析各类现象与心智游移的关系,对于全面了解心智游移现象,明晰其概念及促进心智游移特征的进一步研究具有重要意义。  相似文献

"M世代"多任务处理、碎片化信息摄取的生活方式以及基于大数据的信息量给课堂教学带来了巨大挑战,这主要体现在课堂上学生出现更多的心智游移,导致注意力分散和学习效率下降。本文试图从课堂改革角度提出应对大学生课堂心智游移的影响:提高任务难度+约束手段、时间分割+刺激、实施"桌面无手机"活动、进行体验式教学和训练学生正念技术。同时探索心智游移对课堂教学的积极作用,如整合情绪、提高创造力等。总之,通识课应对心智游移的课堂教学改革目的并非禁止心智游移,而是在引导学生教学过程中减少心智游移的产生。  相似文献

前人的研究主要关注成人的MW ,鲜有针对儿童MW的研究,且研究从未考虑社会因素对于个体MW行为的影响,对MW的主观判断标准的个体差异也未给予足够的重视。本研究以四、五年级的儿童作为被试,让他们完成一个改编的SART (Sustained Attention to Response T ask )任务,并在任务结束后填写一份态度问卷,以探讨持不同外显态度的儿童在任务中心智游移的频率差异,以及他们对于心智游移的主观判断标准差异。研究根据问卷的得分将被试分为积极态度组和消极态度组,结果发现:(1)积极态度组的儿童在任务中的心智游移频率显著高于消极态度组的儿童;(2)积极态度组的儿童无法准确地判断当前自己是否正在发生心智游移。  相似文献

心智游移(mind-wandering,简称MW)是指个体将部分或全部注意转向了内部体验和感受,是一种注意分散状态。通过n-back任务以及go/no-go任务,考察工作记忆广度、工作记忆负载和目标出现概率等因素对MW的影响,借助Broadbent等人编制的认知失败问卷进行实验室情境下MW发生率与实际生活中的分心现象的相关性研究,结果发现:在高负载水平下,被试的MW报告率显著低于低负载水平,高广度组被试比低广度组被试报告更少的MW;目标呈现概率与工作记忆负载存在交互作用,二者共同影响MW报告率;在高负载水平下,目标呈现概率无论大小,MW报告率都较小,而在低负载水平下,目标呈现概率高时MW报告率更小;MW报告率与反应抑制正确率存在负相关,说明MW的发生对于任务反应存在消极影响;MW报告率与个体在CFQ问卷上的得分存在正相关。我们认为心智游移受工作记忆资源的影响,并且实验室情况下的MW与日常生活中的MW具有一定程度的相关。  相似文献

情绪和认知是信息加工系统中两个不可分离的部分,个体的情绪总是渗透在认知活动中。纵观情绪与认知从相互独立逐步走向融合研究的道路.其间研究者们对个体的情绪状态和材料内容的情绪性开展了大量的研究,相应的也提出了大量相关理论:促进假说、抑制假说、双加工理论等。各个理论在对情绪和信息加工的关系研究方面有着重要的作用。但它们大多从单一的视角进行探讨,全面性研究有待提高,另外运用科学手段进行整合性和基础性的研究将是未来的一个发展方向。  相似文献

数学是小学必学的课程之一,它具有系统性、严密性、抽象性的特点。小学生年龄小,心智还不成熟,正处于活泼好动、贪玩的年纪。在这种情况下,如何提高学生学习数学的兴趣成为数学教师研究的重要内容。随着新课改的不断深入,创设有效情境法被引进小学数学教学中去,取得了不错的效果。基于此,本文就对小学数学教学中创设有效情境的策略进行重点研究,以供相关人士参考。  相似文献

化学实验不仅是学生学习化学的一种重要方法和途径,也是化学教学的重要内容。从认识论的角度来看,化学实验能为学生认识化学科学知识、检验化学理论、验证化学假说提供化学实验事实;从方法论角度来看,化学实验具有重要的方法论功能,是落实新课程的“过程与方法”目标的重要手段;从教学论角度来看,化学实验在创设学习情境,  相似文献

本文对1992~2010年间发表在国内学术期刊的有关"关键期"假说的学术论文从研究数量、对象、方法和内容四个方面进行了量化统计和分析。结果显示:(1)虽然相关论文数量并不多,但研究总体呈上升趋势;(2)对象主要集中在儿童;(3)方法以思辨性研究为主,实证性研究为辅;(4)内容侧重于与外语教学实践相结合,国内的相关研究还处于探索阶段,研究的广度和深度不够。基于以上分析,本文提出了"关键期"假说研究在我国的发展趋势,为广大同仁进一步的研究提供参考。  相似文献

汉字倒说     
汉字的六书,《说文》对“转注”一类,语焉不详。后世学者提及转注,也仅限于许慎所举出的例字。《汉字例说》一文,作者从转注的角度综合考虑,对部分现代常用字作了分析,跟传统的解释有所不同。希望能抛砖引玉,互相切磋,以推进学术研究。  相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.  相似文献

The problem on the geometrc inequalities involving an n-dimensional simplex and its inscribed simplex is studied. Aninequality is established, which reveals that the difference between the squared circumradius of the n-dimensional simplex andthe squared distance between its circumcenter and barycenter times the squared circumradius of its inscribed simplex is not lessthan the 2(n-1)th power of n times its squared inradius, and is equal to when the simplex is regular and its inscribed siplex is atangent point one. Deduction from this inequality reaches a generalization of n-dimensional Euler inequality indicating that thecircumradius of the simplex is not less than the n-fold inradius. Another inequality is derived to present the relationship betweenthe circumradius of the n-dimensional simplex and the circumradius and inradius of its pedal simplex.  相似文献

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.  相似文献

Using virtual reality for interactive design gives a designer an intuitive vision of a design and allows the designer to achieve a viable, optimal solution in a timely manner. The article discusses the process of making the Virtual Reality System of the Humble Administrator's Garden. Translating building data to the Virtual Reality Modeling Language (VRML) is by far unsatisfactory. This creates a challenge for computer designers to do optimization to meet requirements. Five different approaches to optimize models have been presented in this paper. The other methods are to optimize VRML and to reduce the file size. This is done by keeping polygon counts to a minimum and by applying such techniques as object culling and level-ofdetail switching.  相似文献

The awareness of individualism can be traced back to the period of American Revolution when the Declaration of Independence was produced.It expressed basic beliefs concerning freedom,equality,democracy,privacy and the relationship between people and government,which were exactly what the philosophy of individualism mostly dealt with at that time.This paper is to exploit the essence of individualism by analyzing the Declaration .The analysis enables us to reconsider its significance to the issue of America human rights and foreign policies.  相似文献

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.  相似文献
