个体解决三项系列问题的心理模型

该研究设计了2种实验条件,对360名6-19岁个体解决三项系列问题的能力发展进行了研究,旨在讨论个体解决三项系列问题的心理模型的发展问题,结果表明：(1)6-19岁个体对三项系列问题中有必然逻辑答案的题目的判断能力的发展速度比较平稳;(2)个体对三项系列问题中有必然逻辑答案的题目的判断能力先于对没有逻辑答案的题目,6-9岁个体对三项系列问题中没有必然逻辑答案的题目的判断能力的发展速度低于10岁以后的个体;(3)空间模型、语义模型、语义一空间混合模型和枢纽项比较模型是相互补充的,是在不同认知发展阶段依一定次序,按一定的阶段逐渐形成的,经历了5个不同的发展阶段,最终形成以枢纽项比较模型为核心、四种心理模型并存于个体的心理结构之中的复合模型。     

Association of Positive and Negative Parenting Behavior with Childhood ADHD: Interactions with Offspring Monoamine Oxidase A (MAO-A) Genotype

Relatively little is known about the potential interplay between genetic and environmental influences on attention-deficit/hyperactivity disorder (ADHD), including gene-environment interaction (G×E). There is evidence that parenting behavior interacts with offspring genotype in the development of externalizing problems, but studies have largely focused on explicit maltreatment rather than differentiated measures of parenting behavior, including positive and negative parenting. We tested the interactive effects of the 30-base pair variable number tandem repeat (VNTR) polymorphism of the monoamine oxidase A gene (MAO-A) with positive and negative parenting behavior on parent- and teacher ratings of inattention and hyperactivity symptoms among 150 6–9 year-old boys with and without ADHD. Negative parenting predicted parent and teacher ratings of inattention symptoms, but only among boys with high-activity MAO-A genotype. MAO-A genotype did not moderate the association of positive parenting and parent- and teacher ratings of ADHD. We discuss the potential role of interactive exchanges between parenting behavior and child genotype in the development and persistence of ADHD and related behavior problems.     

Self-esteem modulates attentional responses to rejection: Evidence from event-related brain potentials

Individuals with low self-esteem have been shown to exhibit an attentional bias for social rejection cues. The present study investigated whether individuals with low self-esteem would demonstrate greater reactivity to rejection-related stimuli during an attention shifting task than was exhibited by those with high self-esteem. Individuals with low self-esteem showed higher amplitude event-related potentials (ERPs) in response to rejection cues than was observed for those with high self-esteem. These results suggest that individuals with low self-esteem allocate more attentional resources to rejection cues than those with high self-esteem. Discussion will focus on the implications of these findings for understanding the connection between low self-esteem and social rejection.     

安全动机在安全绩效模型中的作用：自我决定理论的视角

在日常工作中, 安全动机是员工保持安全行为的重要决定因素。安全动机对安全绩效的影响虽然已引起研究者的关注, 但相关的实证研究缺少清晰的理论界定和有效的测量工具。本项目拟在安全绩效模型的基础上, 借鉴自我决定理论对动机的分类, 将安全动机的类型进行扩展, 并在多层次模型中探讨安全动机在变革型领导、个体特征和安全绩效之间的中介作用, 以及在中国管理背景下可能存在的边界条件。研究将结合访谈、问卷和情境实验等方法对上述变量间关系进行相关和因果关系的探讨。本项目将自我决定理论与安全绩效模型相结合, 可以为安全研究的动机理论发展做出贡献; 研究结果亦可为安全管理实践提供评价工具和有效指导。     

观点采择:概念、操纵及其对群际关系的影响

观点采择是指个体从他人或他人所处情境出发,想象或推测他人观点与态度的心理过程.观点采择能积极或消极地影响群际关系.依照研究内容是否涉及群际互动,可以将前人研究分为静态研究与动态研究.静态研究中,观点采择可以通过自我—他人融合、不公正感知等中介机制影响群际关系.动态研究中,观点采择可能引发反应性自我中心主义与评价关注,进而影响群际关系.未来可以从观点采择的真实干预、对群际冲突感知的影响以及检验观点采择与群际关系的调节变量等角度深入研究.     

汉语为二语学习者言语产生中的跨语言干扰

采用跨语言长时竞争启动范式探讨汉语为二语学习者言语产生中的跨语言干扰。实验1的被试选择18名俄语为母语者, 实验2选择18名日语为母语者。自变量是命名语言(一语和二语)和学习条件(学过一致、学过不一致和未学过), 因变量是测验阶段被试图片命名的反应时和正确率。实验分为学习阶段和测验阶段, 被试分别用一语和二语命名图片, 观察被试在测验阶段学过一致与学过不一致两种条件下是否都能产生促进效应。实验结果发现, 无论俄语为母语者还是日语为母语者, 被试只有在学过一致条件下的反应时显著快于未学过条件, 而学过不一致条件下的反应时跟未学过没有显著差异。本研究结果表明, 汉语为二语学习者言语产生中存在跨语言干扰, 且语言间书写特征的差异对跨语言干扰没有影响。     

情绪启动与语义启动的比较

情绪启动与语义启动发生时孰先孰后、进行中独立平行还是交互作用、效应上孰强孰弱,还存在较大争议.这些争议的本质涉及到人脑中情绪和认知这两大基本系统的关系认识问题.通过行为观察与事件相关脑电位技术结合,在同一个实验中设置情绪启动、语义启动两种情境,并匹配可能影响这两种启动效应的因素,如信息强度、启动刺激和靶刺激的信息关联程度等,然后系统性变化启动刺激呈现的时间、SOA、实验任务等,并逐步加入被试的年龄、性别、学科专业、认知风格、情绪易感性等个体差异变量,可望直接而系统地澄清争议,深层次揭示情绪信息流与语义信息流的加工特点,并进而揭示人脑情绪系统与认知系统功能与机制的发展规律.     

语言理解转换中非目标语言影响目标语言的时间进程

运用跨语言即时启动和延时启动范式,要求被试完成生物属性的语义判断任务,研究语言理解转换中非目标语言影响目标语言语义理解的时间进程。实验1非目标语言为英文,目标语言为中文,结果表明,无论是即时启动(t = -0.423, p = 0.676),还是延时启动(t = -0.82, p = 0.419),语义相关组与语义无关组都无显著差异。实验2非目标语言为中文,目标语言为英文,结果表明,在即时启动条件下,语义相关组显著快于语义无关组(t = -3.05, p = 0.006),但延时条件下语义相关组与语义无关组无显著差异(t = -0.63, p = 0.536)。综合两个实验结果表明,晚期熟练双语者在双语语言理解转换过程中语义的即时启动影响存在不对称性,语义相关的非目标语言中文对目标语言英文语义理解起促进作用;但是语义启动效应没有得到延时体现。     

Two experimental tests of trust in in‐group strangers: The moderating role of common knowledge of group membership

The role that shared group membership plays in decisions to trust others is now well established within social psychology. A close reading of this literature, however, shows that this process is often moderated by other variables. Currently, we examined one potential moderator of this process. In particular, we evaluated the role that common knowledge of a shared social group membership between self and a to‐be‐trusted stranger provides as a basis for trusting this stranger. This common knowledge emerges when the truster knows the group membership of the to‐be‐trusted other, and believes that this other also knows the group membership of the truster. In two experiments, using pre‐existing and minimal groups, we show that people are more likely to trust an in‐group member over an out‐group member under conditions of common group‐membership knowledge rather than private group‐membership knowledge (i.e. other does not know truster's group), even when they could choose not to trust anyone. The manner in which these data add to current understandings of group‐based trust in strangers is discussed. Copyright © 2011 John Wiley & Sons, Ltd.     

Reducing STD/HIV Stigmatizing Attitudes Through Community Popular Opinion Leaders in Chinese Markets

Reducing STDs and HIV/AIDS incidence requires campaigns designed to change knowledge, attitudes, and practices of risky sexual behavior. In China, a significant obstacle to such changes is the stigma associated with these diseases. Thus 1 campaign intervention strategy is to train credible community leaders to discuss these issues in everyday social venues. This study tested the effectiveness of such an approach on reducing HIV/AIDS stigma, across 2 years, from a sample of over 4,500 market vendors, in 3 conditions. Results showed an increasing growth in market communication about intervention messages, and concomitant declines in stigmatizing attitudes, across time, with the greatest changes in community popular opinion leaders, significant changes in intervention nonopinion leaders, and little change in the control markets.
