Psychometric properties of the Padua Inventory in Chinese college samples

The aim of the present study was to investigate the psychometric properties of the Padua Inventory in Chinese college samples. Three different samples (N1 = 1,939, N2 = 1,341, and N3 = 298) of Chinese college students were recruited. Exploratory factor analyses yielded a four-factor structure which was similar to that found in previous studies. Further, present results showed good internal consistency as well as convergent and divergent validity with the subscales of the Symptom Checklist-90 and the Penn State Worry Questionnaire. Although no sex difference was found on total score, women had significantly higher scores on Factor 2 (Urges and worries of losing control over motor behaviors) and Factor 4 (Checking), while men had significantly higher scores on Factor 3 (Contamination). Implications of ter the results and directions for research are discussed.     

The weight of time: affordances for an integrated magnitude system

In five experiments we explored the effects of weight on time in different action contexts to test the hypothesis that an integrated magnitude system is tuned to affordances. Larger magnitudes generally seem longer; however, Lu and colleagues (2009) found that if numbers were presented as weights in a range heavy enough to affect lifting, the "larger seems longer" effect was enhanced, but it was eliminated with weights too light to affect lifting. Experiments 1 and 2 revealed that actually lifting kilogram and gram weights had effects parallel to symbolized weights, suggesting that Lu et al.'s task implicitly evoked a lifting context. Experiments 3 and 4 showed that weights too heavy (e.g., tons) or too light to be discriminated by lifting, but relevant to other affordances (e.g., grams of a toxin) had effects on time as large or larger than for kilograms. Experiment 5 showed that the effect for grams in a toxicology context did not generalize to the lifting task of Experiment 2. Weight appears to integrate with other magnitudes when it is relevant to meaningful actions, including but not limited to lifting.     

汉字认知过程中整字对部件的影响

英文研究中,"字优效应"是单词促进字母加工的一个重要依据。但中文研究中还存在一些争议。本研究通过两个实验考查了汉字的部件认知中,汉字整体对局部(部件)的影响。实验刺激材料分为三种,即左右结构或上下结构的真字、假字与部件字。目标部件为既能够放置于三种字符的左侧,又能放置于右侧(上部或下部)的汉字部件。实验一采用Reicher-Wheeler实验任务,先呈现刺激材料350ms,掩蔽后再呈现需要判断的目标部件,被试对目标部件进行按键反应。实验二中采用部件判断实验任务,先呈现需要判断的目标部件,再呈现刺激材料,被试对刺激材料中是否包含目标部件进行按键反应。记录反应时与正确率。27位健康女性大学生参与本实验。结果显示:(1)不论是Reicher-Wheeler实验任务还是部件判断实验任务,均显示部件字的部件认知判断速度最快。真字与假字相比,无"字优效应"。真字与部件字相比,存在着"字劣效应"。这些结果表明,汉字整字对汉字部件认知加工起到抑制作用;(2)两个实验任务均表现出汉字结构方式效应,即对左右结构的汉字的部件认知比上下结构的汉字更快;(3)部件的空间位置对部件识别存在影响。实验一中对下部件分辨最困难,分辨时间最长;实验二中发现对左部件的反应最快。字符结构方式效应与部件空间位置效应既存在于真字中,也存在于假字中。     

Deep-level diversity and leadership

In the special issue on Diversity and Leadership (April 2010), the authors made a strong case for the importance of diversity in workplace leadership, rejected premature declarations that workplace discrimination is obsolete, and called for leadership theories that acknowledge and promote the value of diversity. We appreciate all authors' stressing that the glass ceiling still exists, not only for women but for other historically low-power groups as well. We also agree that modern theories of leadership can benefit immensely from increased participation by scholars and practitioners who are not Western, White, upper-class men (Chin, 2010).     

社会压力与决策角色对不同人际敏感性个体助人决策的影响

本研究基于人格的交互作用理论,通过时间与金钱两种助人决策情景,设计两个实验考察了人际敏感性特质对个体助人决策的影响,以及决策角色与社会压力两种情境因素在其中的作用。结果发现：(1)相比低人际敏感性,高人际敏感性个体更容易做出助人决策;(2)相比低社会压力,高社会压力下,高人际敏感性比低人际敏感性个体捐助的金钱更多; (3)高社会压力下,相比低人际敏感性个体,高人际敏感性个体为朋友与陌生人决策时会捐助更多的金钱。研究表明：人际敏感性影响个体的助人决策,决策角色与社会压力会对不同人际敏感性个体的助人决策有不同程度的影响。     

国外儿童科学思维发展的新探索

儿童科学思维是发展心理学研究领域的重要的研究课题。最近十年,儿童科学思维发展的研究经历了显著的变化。文章对儿童科学思维发展的研究进行简要回顾,主要阐述有关儿童科学思维发展的特殊领域知识、一般领域策略、概念和策略的整合模型以及微观发生法,并在此基础上,对儿童科学思维发展研究进行简单的评价和展望。     

文本阅读中的信息整合研究

文本阅读中的信息整合研究是当前文本阅读研究的热点问题,在这一问题上,虽然当前研究已经达成了一些基本共识,但仍然存在着建构主义理论、最低限度假设和记忆基础文本加工理论这三种理论争议。本文详细介绍了这三种理论争议的主要观点和实验证据,特别是重点分析了三种理论争议的最新发展,在此基础上对未来的研究趋势进行了展望。     

双语言语产生中的词汇提取机制

文章主要介绍了双语言语产生中词汇提取机制的两种理论：非特定语言提取的理论和特定语言提取的理论。重点围绕着双语言语产生中词汇提取的一个关键问题,即非目标语言的词汇是否对目标语言的词汇提取形成竞争或者干扰详细地论述了二者的理论分歧,非特定语言提取的理论认为非目标语言的词汇会对目标语言的词汇提取形成竞争,而特定语言提取的理论认为不会形成竞争。文章最后介绍了双语言语产生中词汇提取机制的最新研究趋势,表明了非特定语言提取的理论和特定语言提取的理论逐步走向融和     

基于语境的因果性预期推理的构建的实验研究

实验一探讨对因果性预期推理的支持程度不同的语境对因果性预期推理的即时构建的影响。结果表明,如果文本信息有支持预期结果的语境,读者会即时进行因果性预期推理。实验二探讨当文本描述了两个不能整合的情境模型时因果性预期推理的即时构建情况。结果表明,在这种条件下,因果性预期推理不会即时产生。本研究结果表明,文本的语境对因果性结果的支持程度对因果性预期推理的即时构建有决定性的影响作用。     

文本阅读中信息精确化推理的初步研究

采用动窗技术对文本阅读中信息精确化推理进行了初步研究。实验1研究在工作记忆范围内,信息精确化推理是即时发生的还是当局部信息不连贯时再重新追溯才发生。实验2探究信息精确化推理在长时记忆中是否也会发生。结果表明,文本阅读中的信息精确化推理,不管需要进行精确化推理的句子与包含推理所需信息的句子是处于同一工作记忆范围内,还是处于长时记忆中,推理都是即时发生的。
