知觉和概念信息对3岁儿童归纳推理的影响

采用经典的三角归纳范式(Gelman & Markman,1986)研究了3岁儿童的归纳推理及其影响因素。采用龙长权、路晓英、李红和范籍丹(2008)的研究中相同的实验材料和程序,测试了3岁儿童的归纳,结果表明3岁儿童基于知觉相似和基于概念类别之间的差异不显著(实验一)。增加了与靶刺激在知觉上不相似且不属于同一类别的分心刺激之后,3岁儿童能够忽略分心刺激,表明3岁儿童不是在随机猜测(实验二)。分类实验表明3岁儿童能够根据概念关系对实验材料中的项目进行分类,表明3岁儿童具有关于实验项目的概念知识(实验三)。提高概念比较刺激与靶刺激的知觉相似程度,降低知觉比较刺激和概念比较刺激与靶刺激在知觉相似上的冲突程度之后,3岁儿童基于知觉相似和基于概念类别选择之间的差异仍不显著,表明抑制控制不是导致儿童在实验一中表现出基于知觉相似和基于概念类别之间差异不显著的原因(实验四)。降低概念比较刺激与靶刺激之间的类别等级结构,使概念比较刺激与靶刺激属于相同的基本水平类别时,3岁儿童能够主要基于概念类别进行归纳(实验五)。增加经典三角测试的前提的数量,3岁儿童也能主要基于概念类别进行归纳(实验六)。这些研究表明,3岁儿童在一定条件下能够基于概念类别进行归纳,多个因素能够影响3岁儿童在三角测试中的表现。     

3—7岁儿童与成人筷子使用动作模式的比较研究

通过比较3—7岁儿童与成人的筷子使用动作模式类型、特征和使用率,初步探讨了筷子使用动作模式的特点及发展趋势。研究结果表明：(1)儿童与成人中均存在八种筷子使用动作模式,各种模式在手指的分工、配合及完成任务的稳定性、适应性等方面表现出不同的特点,具有不同的效率水平;(2)随年龄的增长,个体筷子使用动作模式日趋转向效率较高的类型,表现为高效模式的使用率从3岁组的3．7％增加到成人组的50％,而低效模式的使用率从59．3％下降到10％。     

Psychological adjustment to cancer in a collective culture

We examined the associations between social support, health locus of control, neuroticism, and psychological adjustment (PA) in 152 Hong Kong Chinese patients. Our objective was to assess hypotheses relevant to the cohesive family structure, and the belief in external sources of control that pervade this culture. Use of social support by individuals who reported reliable support, and internal locus of control (ILOC) associated positively, and neuroticism associated negatively with PA. The independent variables accounted for up to 39% of the variance in PA measures. Our findings provide rare information about coping with serious illness in a non‐Western culture. They illustrate the centrality of family relationships in Chinese culture. They suggest that even in a culture where supernatural beliefs are widespread, ILOC relates positively and “chance” beliefs relate negatively to adjustment. Finally they support the importance of controlling for neuroticism in examining stress.     

重复启动作业中词的语义透明度的作用

用词素重复启动的方法考察合成词的心理表征。目标刺激为２４个语义透明度词、２４个不透明词以及４８个非词（都是两个字）。启动刺激有５种：（１）目标词本身,（２）目标词的第一词素,（３）目标词的第二词素,（４）由目标词的两个词素颠倒后形成的非词,（５）包含目标词的一个词素的非词。启动刺激的呈现时间是１００毫秒,随后是目标刺激４００毫秒。被试的任务是尽快准确地按键判断目标刺激是否是一个词。研究发现,（２）、（３）、（５）条件下的重复启动中,透明度表现出显著的效应：透明词的启动量显著大于不透明词。结果支持合成词的表征受语义透明度的影响,透明词和不透明词的词素和整词在心理表征中的关系可能不同：前者是一种兴奋性的连接,后者是一种抑制性的连接。     

Do groups lie more than individuals? Honesty and deception as a function of strategic self-interest

An experiment tested whether groups lie more than individuals. Groups lied more than individuals when deception was guaranteed to maximize economic outcomes, but lied relatively less than individuals when honesty could be used strategically. These results suggest that groups are more strategic than individuals in that they will adopt whatever course of action best serves their economic interest.     

A test of theory of planned behavior in Korea: participation in alcohol-related social gatherings

Two studies are reported using the theory of planned behavior (TPB) to predict and explain joining and not joining alcohol-related social gatherings among Korean undergraduates in various engineering majors. Specifically, considering that the attitudinal component of TPB is behavioral-outcome-based, the current study investigated whether the outcomes of engaging in a behavior and of not engaging in a behavior would similarly predict intentions to engage in a behavior and intentions to not engage in a behavior. The current study also examined whether intentions to engage and intentions to not engage would be significantly related to self-reported behavior a week later. Participants in Study 1 reported TPB components (attitudes toward behavior, subjective norms, perceived behavioral control, and behavioral intentions) concerning joining alcohol-related social gatherings. Participants in Study 2 reported TPB components concerning not joining alcohol-related social gatherings. Additionally, a week later, the participants in both studies reported their participation in alcohol-related social gatherings from the past week. Generally, the results showed that the TPB components were significantly associated with undergraduates' intentions to join and intentions to not join. Specifically, conversation-related attitudes and senior-junior relationship-related attitudes were significantly related to intentions to join, and only group-related attitudes were significantly related to intentions to not join. Intentions to join and intentions to not join were not significantly related to self-reported behavior of joining alcohol-related social gatherings a week later. The findings from the current research provide some evidence that joining or not joining alcohol-related social gatherings may not be mere behavioral opposites, predictable by the presence or absence of the same behavioral outcomes. These two aspects of the behavior may require assessment of different behavioral outcomes or different assessments of the same behavioral outcomes.     

Scope Processing in Chinese

The standard view maintains that quantifier scope interpretation results from an interaction between different modules: the syntax, the semantics as well as the pragmatics. Thus, by examining the mechanism of quantifier scope interpretation, we will certainly gain some insight into how these different modules interact with one another. To observe it, two experiments, an offline judgment task and an eye-tracking experiment, were conducted to investigate the interpretation of doubly quantified sentences in Chinese, like Mei-ge qiangdao dou qiang-le yi-ge yinhang (Every robber robbed a bank). According to current literature, doubly quantified sentences in Chinese like the above are unambiguous, which can only be interpreted as ‘for every robber x, there is a bank y, such that x robbed y–surface scope reading), contrary to their ambiguous English counterparts, which also allow the interpretation that ‘there is a bank y, such that for every robber x, x robbed y–inverse scope reading). Specifically, three questions were examined, that is, (i) What is the initial reading of doubly quantified sentences in Chinese? (ii) Whether inverse scope interpretation can be available if appropriate contexts are provided? (iii) What are the processing time courses engaged in quantifier scope interpretation? The results showed that (i) Initially, the language processor computes the surface scope representation and the inverse scope representation in parallel, thus, doubly quantified sentences in Chinese are ambiguous; (ii) The discourse information is not employed in initial processing of relative scope, it serves to evaluate the two representations in reanalysis; (iii) The lexical information of verbs affects their scope-taking patterns. We suggest that these findings provide evidence for the Modular Model, one of the major contenders in the literature on sentence processing.

在传统文化与中医学相互渗透影响的历史过程中,传统文化仅在一定时期对中医理论的构建起到直接作用,其它时期则仅仅是一种类比说理之用.伴随着这种变化,医家援文入医的方法及思维方式发生了一定的改变.促使中医生理学理论由生成论向本体论演化,形成了别具特色的命门学说.     

行为博弈与社会交换

行为博弈与社会交换看似两个毫无关联的现象和研究领域,却有着内在的、实质性的联系。行为博弈也是一种社会交换或以社会交换为机制,社会交换则表现为一种行为博弈或有着内在的博弈性质。行为博弈与社会交换互为表里、互为机制、水乳交融,行为博弈是社会交换的行为博弈,社会交换是行为博弈的社会交换。以行为博弈的眼光来看待社会交换或以社会交换的意识来研究行为博弈,跨领域的研究洞视,各自互为对方启动了一方别开生面的研究天地,为枯燥乏味的传统博弈研究和死水微澜的社会交换领域凭添了一丝新鲜气息。
