行为遗传学研究之新进展

自上世纪80年代以来,行为遗传学取得了长足的进展。在定量遗传学方面,共享环境和非共享环境概念的引入深化了人们对环境作用的认识;对于环境和遗传关系,不仅认识到基因型-环境的交互作用可能存在三种形式,还揭示出遗传对环境测量的影响——基因型-环境的相关。分子遗传学作为新兴的研究途径,目前以寻找基因为主,将来则以认识基因如何工作为重。行为遗传学的发展前景将是定量遗传学和分子遗传学以行为基因组学为中心的整合。     

中学生英语学习策略水平及其与英语学业成绩的相关研究

本研究运用《学生学习策略评价表》对安徽省两所中学的239名学生进行调查,考察中学生的英语学习策略水平及其与英语学业成绩的关系.结果发现:(1)中学生英语学习中经常使用的学习策略多集中于认知和调控策略.(2)省示范高中与一般中学学生在英语学习策略存在显著差异.性别上则不存在显著差异.(3)中学生的英语学习策略及其认知和调控策略与学生学业成绩之间呈显著正相关,交际和资源策略与学生的学业成绩则没有显著相关.     

不同沟通方式下群体决策信息利用分析

以180名被试组成45个四人群体．完成模拟人事选拔的问题解决型任务,通过对群体决策过程的信息提取数量和提取次序的分析,考察不同的沟通方式和信息分享程度对群体决策信息利用的影响。结果表明。（1）在不同沟通方式下,决策成员的讨论前偏好对最终决策的影响很大。（2）在不同的沟通方式下,分享程度不同的信息在决策过程中的提取具有差异,体现了不同的规律。     

左右半球在语篇理解中的协同作用

通过2例一侧颞叶损伤患者研究了一侧颞叶损伤及两侧半球的协同作用对语篇理解的影响,并探讨了发生此种影响的可能机制。结果表明一侧颞叶的损伤将导致患者语篇水平的理解障碍及语言推理能力的下降;提示语篇理解需双侧半球的协同作用,而推理能力下降可能是引发语篇理解障碍的原因之一。     

认知过程中的捆绑问题--认知神经科学的研究

捆绑问题是当前脑科学研究中的主要问题之一,近来已成为意识争论的焦点。该文结合国外对捆绑问题研究的最新成果,在概括介绍关于捆绑机制的主要理论的基础上,综述了捆绑问题与主要认知功能关系的研究,并指出不同认知过程中捆绑脑机制的精细化研究和一般性捆绑脑机制的系统化研究可能是今后这方面研究的重点。     

Microblogging, online expression, and political efficacy among young chinese citizens: the moderating role of information and entertainment needs in the use of weibo

In 2011, China's Internet population reached over half a billion users and the popular Twitter-like social networking service, Weibo, has been adopted by half of the users since its launch in August 2009. Given the potential of the Internet to facilitate a civic culture in the authoritarian state, the use of Weibo and its effects on citizens' political attitudes and behaviors are of important concern. A survey of 499 Weibo users found that intensity of use was related to increased willingness to express opinions about government and politics, the perception that one has the ability to participate in politics, and feelings that the government is not responsive to the demands of citizens. Moreover, the above relationships were moderated by the motivations of Weibo use, such that information motives strengthened the relationships while entertainment motives weakened the relationships.     

Are people always more risk averse after disasters? Surveys after a heavy snow‐hit and a major earthquake in China in 2008

China suffered both a heavy snow‐hit and a major earthquake in 2008. To investigate the effects of disasters on risky decision making, opportunity samples were obtained by recruiting residents in both devastated and non‐devastated areas. In a survey (Study 1) conducted shortly after the heavy snow‐hit, we found that people were not always more risk averse after a disaster as previous studies had claimed and that they were inclined to approach an option with ‘low probability associated gain’ and to avoid an option with ‘low probability associated loss’. These findings were replicated in a consecutive survey (Study 2) conducted after the Wenchuan earthquake. It was further found that the popularity of both insurance and lottery, which presumably contributed to overweighing of small probabilities, was detected to have been enhanced with substantial exposure to the earthquake disaster. The implications of these findings for risk education and government policy making were discussed. Copyright © 2009 John Wiley & Sons, Ltd.     

"意-象-言"的解构与中医研究

中医理论难以用逻辑语言进行现代化表述被归因于其以"象"表"意"的理论体系.从中医认知、思维和传承体系"意-象-言"的角度出发,力求厘清三者的含义以及三者之间的关系,分析现代化语言表述困难的真正原因,提出对"象"和"意"进行分类鉴别,提取出其背后蕴含的基础理论,运用新的语言对中医理论重新表述的可能性.

卷入对名人广告信息加工效果的影响

使用过程分离程序,考察卷入的两方面(个人卷入与产品卷入)共同对名人广告信息加工效果的影响。发现:(1)个人卷入和产品卷入的提高都能促进受众的品牌记忆,但个人卷入的变化主要影响品牌外显记忆成绩,而产品卷入的提高则表现为内隐记忆效果的增强。说明,两者影响的是同一内部过程,但影响方式可能有异。(2)名人广告中的品牌所获得的外显记忆、内隐记忆效果均明显好于使用一般代言人的品牌;代言人类型与个人卷入或产品卷入间不存在明显的交互作用。说明,名人代言人的使用可促进广告信息的加工,且受卷入状态的影响较小。
