Categories of Large Numbers in Line Estimation

How do people stretch their understanding of magnitude from the experiential range to the very large quantities and ranges important in science, geopolitics, and mathematics? This paper empirically evaluates how and whether people make use of numerical categories when estimating relative magnitudes of numbers across many orders of magnitude. We hypothesize that people use scale words—thousand, million, billion—to carve the large number line into categories, stretching linear responses across items within each category. If so, discontinuities in position and response time are expected near the boundaries between categories. In contrast to previous work (Landy, Silbert, & Goldin, 2013) that suggested only that a minority of college undergraduates employed categorical boundaries, we find that discontinuities near category boundaries occur in most or all participants, but that accurate and inaccurate participants respond in opposite ways to category boundaries. Accurate participants highlight contrasts within a category, whereas inaccurate participants adjust their responses toward category centers.     

中学生生活满意度的跨文化比较研究

目的:比较不同国家(地区)中学生生活满意度的差异。方法:运用《多维学生生活满意度量表》对爱尔兰、美国、高加索、以色列、中国五个国家(地区)共计1345名中学生的生活满意度进行了测量。结果:(1)五国(地区)中学生高一般生活满意度组人数分布百分比由多到少依次为爱尔兰、美国、高加索、以色列、中国;(2)五国(地区)女生的家庭满意度高于男生,男生的学校满意度高于女生;(3)爱尔兰学生的家庭满意度最高,中国学生的朋友和学校满意度最高,以色列学生的生活环境满意度最低、自我满意度最高;(4)性别和国家(地区)对中学生的学校、生活环境、自我的满意度存在交互作用。结论:不同国家(地区)中学生的生活满意度存在差异,社会文化背景是影响中学生生活满意度的重要因素。

差异与互补:皮亚杰与维果茨基认知发展观比较的新思考

皮亚杰与维果茨基是10世纪两位最有影响的发展心理学家．他们开辟了研究儿童发展的两条线路。这两种取向存在着根本性的差异,同时在研究方法与具体观点中又存在着多方面的类似和交叉．两种取向互动互补．共同描绘了儿童发展的整体画卷。     

妒忌:一种带有敌意的社会情绪

妒忌是个体因为意识到别人拥有自己所缺乏的优势时体验到的一种消极感受,表现为自卑、敌意和怨恨的一种混合情绪,包括特质和状态两种界定角度.相似性、自我相关是妒忌的近因,资源竞争则是妒忌的远因,前扣带皮层、腹侧纹状体和腹中侧前额叶是妒忌加工和识别的相关脑区.妒忌影响人们的身心健康、攻击行为、道德行为、幸灾乐祸、亲社会性以及业绩表现.未来研究可以在善意妒忌、内在机制、进化视角、文化差异等方面进一步扩展.     

Examining a model of dispositional mindfulness, body comparison, and body satisfaction

The present study examined the links between dispositional mindfulness, body comparison, and body satisfaction. It was expected that mindfulness would be associated with less body comparison and more body satisfaction. Two models were tested: one exploring body comparison as a mediator between mindfulness and body satisfaction and an alternative model exploring mindfulness as a mediator between body comparison and body satisfaction. In an online survey, 1287 Dutch women answered questions concerning dispositional mindfulness, body comparison, and body satisfaction. Results showed that body comparison was related negatively to both dispositional mindfulness and body satisfaction, whereas the two latter variables were related positively. Body comparison partially mediated the relation between mindfulness and body satisfaction. However, a stronger indirect effect was noted in the alternative model, where mindfulness partially mediated the link between body comparison and body satisfaction.     

竞争情境下社会比较认知偏差实验研究

本文以在校大学生为被试,考察社会比较的一个重要领域—学业竞争中的比较偏差。通过操纵竞争双方的实力(强VS.弱)以及竞争对手的信息清晰度(清晰VS.模糊)来考察不同的任务类型与信息清晰度对竞争中认知偏差的影响,以及探讨认知偏差对决策者决策意图的影响。结果发现,在社会比较中,面对不同类型的问题,会出现不同的认知偏差;竞争双方信息清晰时优于常人效应会减弱;认知偏差会影响个体的决策意图和决策行为。     

Individual differences in children's mathematical competence are related to the intentional but not automatic processing of Arabic numerals

In recent years, there has been an increasing focus on the role played by basic numerical magnitude processing in the typical and atypical development of mathematical skills. In this context, tasks measuring both the intentional and automatic processing of numerical magnitude have been employed to characterize how children’s representation and processing of numerical magnitude changes over developmental time. To date, however, there has been little effort to differentiate between different measures of ‘number sense’. The aim of the present study was to examine the relationship between automatic and intentional measures of magnitude processing as well as their relationships to individual differences in children’s mathematical achievement. A group of 119 children in 1st and 2nd grade were tested on the physical size congruity paradigm (automatic processing) as well as the number comparison paradigm to measure the ratio effect (intentional processing). The results reveal that measures of intentional and automatic processing are uncorrelated with one another, suggesting that these tasks tap into different levels of numerical magnitude processing in children. Furthermore, while children’s performance on the number comparison paradigm was found to correlate with their mathematical achievement scores, no such correlations could be obtained for any of the measures typically derived from the physical size congruity task. These findings therefore suggest that different tasks measuring ‘number sense’ tap into different levels of numerical magnitude representation that may be unrelated to one another and have differential predictive power for individual differences in mathematical achievement.     

态度改变：说服策略研究的回顾与展望

态度是社会心理学研究的重要领域,近年来研究者发现通过说服可以改变个体的态度,所以态度的说服策略成为一个研究的重点。说服包括了陈述论据和事实,推理,做结论和说明所推荐行为方式的积极效果,所有的一切都是为了使受众相信并且按照这种行为方式行事。本文沿着历史的脉络,从不同的角度阐述了各种说服策略的理论解释及其实验研究,并在此基础上叙述了说服策略未来研究趋势。
