具体认知和抽象认知与社会文化因素的关系

采用认知测试、查阅人类学资料、现场调查和谈话等多种方法,探讨了我国不同生产方式、不同地区和不同民族４６０名成人的具体认知、抽象认知和认知方式及其与生态文化因素的关系。研究结果基本支持了我们理论上所假设的社会文化因素与具体认知操作、抽象认知操作、认知方式的关系,即狩猎和城市社会的生态环境和生产方式对人施加一种生态压力,增进其个体的具体的和抽象的认知,促使其抽象型认知方式的形成;而在捕鱼、游牧和农耕社会的生态环境和生产方式的作用下,个体倾向于较低水平的具体和抽象认知操作以及具体型的认知方式。紧密的社会结构和强调服从的社会化过程,与其个体较低水平的具体和抽象认知及具体型的认知方式相关联;而松散的社会结构和强调自主性的社会化过程,与较高水平具体和抽象认知操作、抽象型的认知方式相联系。正规教育等现代化因素是促进人认知,特别是抽象认知的有力因素。     

稷下学术精神与当代学术发展

稷下学术精神是我国传统学术文化的宝贵遗产,它蕴涵五个基本元素,即学术与政治的和谐互动、学术批评与学术争鸣、学术开放与学术对话、学术人才与学术自由、学术创新与学术实践.这五个元素在学术发展价值意义上起到的是土壤优质、脊梁挺直、血脉涌动、风貌洒脱、动力强劲的良好作用.我们学术界的一个急不可待的任务,是必须克服目前由于经济大潮给人们带来的浮躁心态和狂妄心理,应该沉静下心思来认真发掘和钻研老祖宗、贤人志士们留下的学术的真精神,扎扎实实地做好学术发展的每一个环节、每一件事情.稷下学术精神对当代中国学术发展的启示和借鉴作用是无论如何也不可忽视的.

西南少数民族教育价值观的调查研究

在文献综述、开放式问卷和个别访谈的基础上,提出了西南少数民族教育价值观的理论构想,自编了西南少数民族教育价值观量表。约1,500名西南地区少数民族被试接受了测试。研究表明,该量表具有良好的信度和效度,西南少数民族的教育价值观包括教育效用、家族荣誉、个人发展、民族传承等四个维度,西南少数民族群众的教育价值观在性别和年龄不存在显著性差异,在民族和文化程度上存在着显著性差异。     

Ursolic acid attenuates lipopolysaccharide-induced cognitive deficits in mouse brain through suppressing p38/NF-κB mediated inflammatory pathways

Evidence indicates that systemic administration of lipopolysaccharide (LPS) induces brain inflammation, ultimately resulting in cognitive deficits. Ursolic acid (UA), a plant-derived pentacyclic triterpenoid, is well known to possess multiple biological functions, including antioxidant, anti-tumor and anti-inflammatory activities. In the present study, we assessed the protective effect of UA against the LPS-induced cognitive deficits in mice. We found that UA significantly improved cognitive deficits of LPS-treated mice in open field, step-through passive avoidance and Morris water maze tasks. One potential mechanism of this action was attributed to the decreased production of pro-inflammatory markers including COX-2, iNOS, TNF-α, IL-1β, IL-2 and IL-6 in LPS-treated mouse brain. Mechanistically, UA markedly inhibited LPS-induced IκBα phosphorylation and degradation, NF-κB p65 nuclear translocation and p38 activation in mouse brain, but did not affect the activation of TLR4, MyD88, ERK, JNK and Akt. Taken together, these results suggest that UA may be useful for mitigating inflammation-associated brain disorders by inhibiting pro-inflammatory factors production, at least in part, through blocking the p38/NF-κB signaling pathways.     

内隐和外显记忆任务之间的实验性分离:刺激的不同呈现形式的作用

通过操纵目标刺激的表面形式变化,在内隐和外显记忆任务之间,发现了实验性分离现象,图形识别任务受到了这种操纵的影响,再认任务则没有,同时发现,它们存在着依赖性的关系。对比相关研究,该实验结果表明,概念驱支任务对刺激的表面或知觉的物理性表现出敏感性,是在刺激的编码阶段;数据驱动任务在码阶段和提取阶段,均对其表现出敏感性,在刺激的提取阶段,这两种类型任务提取了刺激的某些共同成分。     

Psychological Adaptation of Chinese Sojourners in Canada

Psychological adaptation during acculturation was studied among 68 Chinese sojourners (students and visiting scholars from China and Hong Kong), 28 Chinese immigrant and Chinese-Canadian students, 30 Chinese students and scholars in China, and 33 non-Chinese Canadian students. Each participant completed questionnaires pertaining to various aspects of their lives and personalities, including: health beliefs and behaviours; problems and ways of coping; social contact and acculturation attitudes; psychological and physical health; and subjective adaptation. The Chinese sojourners reported lower English fluency, lower ease of making friendships, more adaptation and communication problems, and lower subjective adaptation than non-Chinese Canadian, or Chinese-Canadian students. The Chinese sojourners experienced less desired and actual contact, more contact incongruity, more separation and less assimilation than Chinese-Canadian students. The Chinese sojourners reacted to their problems with less wishful thinking and self-blame, and more tension reduction, and the seeking of informational support than non-Chinese Canadian students. There were significant differences between groups in health concept and health causation, and believed and utilized health ways. Health causation, and believed and utilised health ways were the most important factors influencing the Chinese sojourners' health status. The Chinese sojourners experienced more problems, but tended to use fewer health ways after-arrival than pre-departure. The Chinese also experienced poorer health, especially poorer psychological health after-arrival than pre-departure. The longitudinal and cross-sectional analysis of the Chinese sojourners' Cawte scores supported the U-curve hypothesis.

创伤个体注意控制、焦虑及情绪对闯入记忆的影响

以往研究认为认知控制在闯入记忆的发展中起一定作用。研究以83名大学生本科生为被试,采用创伤电影范式和问卷调查结合的方式,旨在考察创伤个体注意控制、焦虑及情绪对闯入记忆的影响。结果显示,注意控制、焦虑和情绪与闯入记忆相关;注意控制和观看创伤电影前的消极情绪对闯入记忆有一定的预测作用;注意控制与焦虑、情绪相关;高低注意控制组分别在焦虑、情绪上差异显著。注意控制、焦虑、创伤前负性情绪与闯入记忆相关;注意控制、创伤前负性情绪显著影响闯入记忆。 关键词：闯入记忆;注意控制;焦虑;情绪;创伤     

分类中相似性的理论与模型

相似性在分类的原型理论、样例理论、定义理论和理论解释观中都扮演着重要的角色。人们对相似性的研究由来已久,但是它在分类的领域中至今仍是一个相对模糊的概念,这部分地由于揭示相似性的真正机制将涉及到复杂的信息加工过程。本文以分类中的相似性为出发点介绍了近期相似性研究的一些理论与模型并在此基础上对概念和分类领域中的相似性研究进行了分析和总结。
