科学发明情境中问题提出的fMRI研究

本研究中, 以76个科学发明问题(36个带有相关的原型, 40个不带有相关的原型)为实验材料,使用功能性磁共振成像(fMRI)技术探讨了科学发明情境中的问题提出以及新近获得的语义对有价值的科学问题提出的启发效应的大脑机制。对有原型提出有价值的科学问题与无原型提出一般问题这两种情况下被试反应的数据进行记录和分析。结果表明两种情况下共同激活的脑区(科学发明情境中问题提出的脑区)为左侧梭状回、左侧内侧额叶、左侧豆状核、右小脑和左侧中央前回。这些共同激活的脑区表明：左侧梭状回也许与各个语句的语义表征有关; 左侧内侧额叶也许与所有语句的整体语义表征以及提出各个语义之间的“问题”有关(左侧豆状核和右小脑配合内侧额叶分别负责控制注意、眼动的指向和注意资源的分配); 左侧中央前回可能负责用语句表述出所提出的语义之间的“问题”。对有原型提出有价值的科学问题和无原型提出有价值的科学问题这两种情况下被试反应的数据进行记录和分析。结果表明有原型提出有价值的科学问题比无原型提出有价值的科学问题显著激活的脑区(科学发明情境中新近获得的语义对有价值的科学问题提出的启发效应的脑区)为左侧楔前叶、左侧额下回、左侧颞中回。这些显著激活的脑区表明：楔前叶与情境记忆的贮存和提取有关; 额中回与认知控制和注意资源的分配有关; 颞中回与新异性原型的成功激活有关。     

Effects of a brief video intervention on White university students' racial attitudes

The authors investigated the effects of a brief video intervention on the racial attitudes of White university students. One hundred thirty-eight self-identified White students were randomly assigned to either an experimental condition in which they viewed a video documenting the pervasiveness of institutional racism and White privilege in the United States or a neutral control condition. Findings offer preliminary support that participants in the experimental, but not the control, condition showed significant increases in racial awareness (i.e., decrease in racial color-blindness), White empathy, and White guilt, at posttest. However, no significant differences in racial prejudice or White fear of racial minorities were observed at posttest. Implications for multicultural counseling training, diversity programming, and future research are discussed.     

和谐社会构建中的心理和谐问题探析

心理和谐是构建社会主义和谐社会的基础和实质,是和谐社会的题中应有之义。心理和谐是人的一种积极向上、健康的人生态度和生存状态,对内协调和对外适应是心理和谐的集中体现。心理和谐主要涉及自我和谐,人际和谐,人与自然和谐以及人与社会和谐四个层面,四个层面相互影响、相互制约。心理和谐是一个持续变化的动态过程,是一种相对的理想状态,心理和谐是心理健康的本质特征;主观幸福感是心理和谐的重要心理指标。     

差异分数的信度分析

本文提出差异分数的信度变化问题,并以模拟数据分析了差异分数的信度在不同情况下的变化规律。结果指出：1．当两次测试得分的信度系数相等或相近时,两次测试的标准差相差越大,差异分数的信度越高。2．当两次测试得分的信度系数不等时,只要两次施测中任何一次的信度和标准差同时大于另外一次,那么差异分数的信度也比较高。3．无论两次测试的信度关系如何。两次测试相关越低,差异分数的信度越高。     

自我认知类型引导认知方式的实验研究

对自我的认知引导认知和行为。本研究用与自我有关的语义内容启动场独立型和场依存型自我认知,随即让被试做与场独立或场依存认知方式有关的认知作业,探讨自我认知类型是否引导认知方式,即启动场独立自我认知是否比启动场依存自我认知诱发更多场独立的认知方式;同样,启动场依存自我认知是否比启动场独立自我认知诱发更多的场依存的认知方式。结果是肯定的。     

亚里士多德的技艺概念:图景与问题

一技艺、技术、艺术与同时代的许多其他希腊哲学家一样,亚里士多德理解的同技术有关的概念是技艺(t′εχνη),这个概念包含着技术与艺术,两者在其中未加分别。他的这种理解方式来自柏拉图。柏拉图把工匠的制作活动和诗文、绘画的创作活动都作为运用技艺的活动来谈论。对柏拉图来说,理解技艺的重要之点在于,它是一种善,一种能力,但不是自然给予人的装备,而是人通过经验的学习获得的能力;因此也不是人人均享的,而是只为一部分人具有的;同时,运用这种能力的活动同理论的活动和实践的活动都不同。亚里士多德的讨论在这个基础上特别加深了对运…     

Doing business: an obscure notion of the ethics of public associations in ordinary Chinese

Along with the notion of being a person (zero run 做人), the notion of doing business (zuo shi 做事) in ordinary Chinese is basically an over-all notion of the norms in the practical and associative activities, carrying typically obscure meanings on practice and association affairs in some external world. Ordinary Chinese not only distinguishes these two notions but also defines a dictionary order of them, with the affairs of the internal world prior to those of the external. The fact that the notion of doing business refers to business (shi 事) rather than person (ren 人) makes this order clear at a deeper level. It shows that this notion regards the practical affairs of the external world less important to the person itself than those of the internal. Except for these qualities, the notion of doing business holds some normative meanings, although contains no definite rules. These meanings indirectly relate to the notion of person that people form in their private associations and emerge as some mixture with a tactical attitude out of the need of earning a life. The notion of person gives birth to some obscure requirements, for instance, the requirement of ‘doing business in accordance with your conscience’ and that of ‘doing business seriously’. The core world of family is marginalized in the public transition of associations. There are reasons to anticipate that in this process the notion of doing business will undergo more radical changes than that of being a person. __________ Translated from Zhexue Yanjiu 哲学研究 (Philosophical Studies), 2005 (7)     

The resilience status of Chinese left-behind children in rural areas: a meta-analysis

The resilience has become the main trend of the left-behind children's (LBC) mental health research. To evaluate the resilience status of Chinese LBC in rural areas, a meta-analysis was performed. Relevant studies were identified using electronic databases from 1990 to 2017. Pooled weighted mean difference (WMD) and 95% confidence interval (95% CI) were calculated with fixed and random effects models. A total of 14 cross-sectional studies with 9777 individuals were included in this meta-analysis. The results showed there was significant difference in the aspects of family support and RSCA (Resilience Scale for Chinese Adolescents) total score between LBC and non-left-behind children (NLBC). After stratification subgroup, significant difference in RSCA total score was also found in subgroup with sample size ≥700 and target population (LBC) between LBC and NLBC. In addition, there was no significant difference in resilience of male and female among LBC (P >0.05). We also found RSCA total score of LBC whose one parents migratingwere higher than both parents (P <0.05) and the time of parental migration (≤2 years) were higher than others (>2 years). In conclusion, more attention should be paid to the LBC, especially both parents migrating or parental migration (>2 years).     

预测视角下双因子模型与高阶因子模型的一般性模拟比较

高阶因子模型本质上是一种特殊的双因子模型, 应用中却常被当做双因子模型的竞争模型。已有研究以满足比例约束的双因子模型(此时等价于一个高阶因子模型)为真实测量模型产生模拟数据, 比较了用双因子模型和高阶因子模型作为测量模型的预测效果。本文使用不满足比例约束的双因子模型(此时不与任何高阶因子模型等价)为真实测量模型产生模拟数据进行比较, 所得结果与满足比例约束的双因子模型的结果有很大差别, 双因子模型结构系数的相对偏差较小、检验力较高, 但第Ⅰ类错误率略高。结论是, 在比例约束条件成立时可以使用高阶因子模型, 否则, 从统计角度看, 一般情况下使用双因子模型进行预测比较好。     

关于青少年应对风格的调查研究

该文采用天津师大编制的应对风格量表对江西省4072名从小学五年级到大学三年级的学生进行了调查,目的是了解青少年应对风格现状及其发展特点,以及性别、独生子女、城乡等因素对应对风格的影响。结果发现：总体而言,青少年应对风格倾向“注重问题的应对策略”,较少采用“注重情绪表达的策略”;在初一年级前后,个体采用的应对方式最为多样化;男女生的应对风格差异在高中后较为明显,男生更倾向于采用“注重问题的应对策略”,女生更倾向于采用“针对情绪的身体策略”;城镇学生的应对方式比农村学生更为多样化,并且更倾向于针对问题本身的策略;家庭收入只对“针对情绪的行为策略”产生影响,高、低两端收入家庭的学生更倾向于采用“针对情绪的行为策略”;是否独生子女在应对风格上不存在显著差异。
