Satisficing when buying information

In two studies expected value, expected utility, and satisficing approaches to one's decision to buy information were compared. The task for the first study was to judge the maximum worth of information by bidding to reduce an ambiguous prospect to a risky one when given an option between a risky prospect and an ambiguous one. A within-subjects design was used in which, for the risky prospect, the probability of gain and expected value were varied. The results were inconsistent with both expected value and expected utility models, but were consistent with a satisficing strategy. The second study was similar to the first but with context changes in the stimuli and a slightly different decision task. The results showed that the effects are robust across task and context. The main behavioral effect is that people appear more willing to buy information that may decrease an expected loss than information that may increase an expected gain. A decision justification principle is consistent with that effect.     

初中生同伴圈子的发展及其对合作倾向、预期和行为的影响

在社会化过程中,同伴圈子不仅决定儿童青少年的交往范围和互动质量,而且影响其心理发展和社会适应。本研究从苏州市某初级中学选取768名初一学生进行了为期一年的追踪,采用社会认知地图、合作倾向评定量表和公共物品困境实验范式测查了同伴圈子、合作倾向、预期与合作行为,运用多层线性模型技术（Two-level HLM）探讨同伴圈子的合作水平对个体合作水平的影响。结果发现：（1）女生圈子数量最多而规模最小,男女混合圈子规模最大而数量最少;跨地域圈子数量最多且规模最大;（2）女生圈子最为稳定,男女混合圈子最不稳定;（3）在混合性别圈子中,个体的合作预期与行为更容易随着圈子合作预期水平的提高而增强;而在单性别圈子中,个体的合作预期与行为更容易随着圈子合作行为水平的提高而增强。结论：初中生同伴圈子在性别上具有同质性,女生圈子多且稳定;第一年单性别和混合性别圈子的合作倾向、预期和行为水平对第二年个体的合作水平产生了不同影响,即不同性别圈子对个体的影响模式存在差异。     

Considering self‐interests and symbolism together: How instrumental and value‐expressive motives interact to influence supervisors’ justice behavior

Drawing upon functional theories of attitudes and the organizational justice literature, the current research suggests that people's attitudes toward justice likely serve an instrumental function (grounded in self‐interest, rewards maximization, and punishment minimization) as well as a value‐expressive function (grounded in the expression of self‐concept and values). Importantly, these two functions co‐exist and interact to influence supervisors’ justice behavior and the consistency of such behavior via supervisors’ justification for unjust behavior. Findings from a set of experimental and correlational studies confirmed these predictions. The positive effects of supervisors’ value‐expressive function on justice behavior and its consistency were stronger when their instrumental function was lower (vs. higher), and justification for unjust behavior mediated these effects. Also, supplementary analyses showed that the consistency of supervisors’ justice behavior positively predicted subordinates’ overall justice perceptions beyond the effects of the overall level of justice behavior. We conclude by discussing the theoretical and practical implications of these findings.     

Exploring a Source of Uneven Score Equity across the Test Score Range

Score equity assessment (SEA) refers to an examination of population invariance of equating across two or more subpopulations of test examinees. Previous SEA studies have shown that score equity may be present for examinees scoring at particular test score ranges but absent for examinees scoring at other score ranges. No studies to date have performed research for the purpose of understanding why score equity can be inconsistent across the score range of some tests. The purpose of this study is to explore a source of uneven subpopulation score equity across the score range of a test. It is hypothesized that the difficulty of anchor items displaying differential item functioning (DIF) is directly related to the score location at which issues of score inequity are observed. The simulation study supports the hypothesis that the difficulty of DIF items has a systematic impact on the uneven nature of conditional score equity.     

齐《易》学刍议

在经学发展过程中,齐经学的地位至关重要,这主要表现为齐人对儒经的传授、齐经学成为汉代经学的主流等方面。而齐《易》学是齐经学的重要组成部分,本文将在齐《易》学的渊源、齐《易》学的传承以及齐《易》学的主要特点与影响等方面试作探讨。     

类比推理的发展理论评析

类比在认知科学领域具有特殊的地位,儿童类比推理能力的发展是其认知发展的重要成分之一。本文系统介绍了类比推理发展研究中的几个重要理论,即能力限制说、知识经验说和关系转换说等。在此基础上,作者进一步对类比推理发展研究中涉及的几个焦点问题,如类比推理出现的最早年龄,类比推理发展的影响因素及类比推理的发展趋势等进行了综合评析。     

《大乘广百论释论》中佛教与胜论派、数论派关于因果问题的辩论

本文依据《大乘广百论释论》中《破有为相品第七》的有关内容对佛教、数论派和胜论派的因果观进行讨论、分析和比较。文章认为,胜论派把因果关系理解为要素的结合,数论派把因果关系理解为潜在事物的显现。无论胜论派还是数论派,都认为世间存在常住不变的实体。《大乘广百论释论》的作者正是抓住这一点来反驳胜论派和数论派的因果观。佛教认为,没有独立、恒常的实体,这是因果律得以成立的前提;所谓的因果联系就是一切无常变化、互相依存的有为法相互联结的条理而已。     

方言经验对早期沪语儿童汉语语音意识的影响

已有研究对汉语儿童的英语语音意识进行研究,且取得了很多有价值的研究成果,但对方言儿童的汉语语音意识的研究很少。汉语是一种具有众多方言的独特语言,许多方言和标准语的语言体系有着显著差异。具有方言和普通话早期经验的双语儿童在汉语语音意识上是否存在优势,有两种不同的看法：一是从心理语言学层面上,母语学习中获得的语言能力或普遍语法能促进第二语言的学习;二是从语言学层面上来讲,母语对第二语言的学习存在干扰作用。那么双语儿童在汉语语音意识上比单一普通话儿童是否存在优势呢？本研究将进行调查。实验选取72名4岁、5岁和6岁学前儿童为被试,每个年龄组各24人,其中沪语儿童和单一普通话儿童各12名。采用听觉呈现方法对所选被试进行汉语语音意识水平的测试,包括声调意识、声母意识和韵母意识三部分,并收集儿童的口语资料。结果表明: 虽然沪语儿童声母意识和韵母意识主效应不显著,但沪语儿童语音意识总成绩和声调意识成绩均比单一普通话儿童高;沪语儿童汉语语音意识优势不受年龄的影响。本研究启示是,上海地区学前儿童学习标准语（普通话）之外应鼓励使用沪语。     

近五年西方心理学重要期刊发表论文简评

摘要：以《心理学公报》、《心理学评论》和《心理学年度评论》三种心理学国际权威学术期刊从2005年到2009年发表的论文为基础,从研究领域、研究主题、引用率等方面对国际心理学的研究进行了文献计量分析。探讨了心理学发展趋势,指出基础/实验心理、社会心理和健康心理领域的研究仍然是心理学研究的主流,但研究方法、技术发生了根本改变;认知、学习与记忆、决策与判断、情绪健康等主题是心理学研究的热点,从而启发中国的心理学研究者应加强研究方法和统计的训练,关注研究的本土化,进行跨学科、多层次整合的研究以及拓展研究主题。
