资源两难问题的研究及其新进展

作为多人社会两难问题的基本范式之一,近年来资源两难问题引起了包括社会学家、经济学家和心理学家在内诸多领域研究者越来越多的关注。文章介绍了资源两难问题的定义、特点、研究意义并总结了以往的研究成果,着重介绍了Samuelson和Messick于1994年提出的资源两难决策模型。在此基础上进一步指出以往研究存在的一些不足,如忽视了对不确定性的研究等。文章最后指出了近年来有关资源两难问题的研究在心理学界的发展,并提出了对以后研究的一些建议。     

Testing domain general learning in an Australian lizard

A key question in cognition is whether animals that are proficient in a specific cognitive domain (domain specific hypothesis), such as spatial learning, are also proficient in other domains (domain general hypothesis) or whether there is a trade-off. Studies testing among these hypotheses are biased towards mammals and birds. To understand constraints on the evolution of cognition more generally, we need broader taxonomic and phylogenetic coverage. We used Australian eastern water skinks (Eulamprus quoyii) with known spatial learning ability in three additional tasks: an instrumental and two discrimination tasks. Under domain specific learning we predicted that lizards that were good at spatial learning would perform less well in the discrimination tasks. Conversely, we predicted that lizards that did not meet our criterion for spatial learning would likewise perform better in discrimination tasks. Lizards with domain general learning should perform approximately equally well (or poorly) in these tasks. Lizards classified as spatial learners performed no differently to non-spatial learners in both the instrumental and discrimination learning tasks. Nevertheless, lizards were proficient in all tasks. Our results reveal two patterns: domain general learning in spatial learners and domain specific learning in non-spatial learners. We suggest that delineating learning into domain general and domain specific may be overly simplistic and we need to instead focus on individual variation in learning ability, which ultimately, is likely to play a key role in fitness. These results, in combination with previously published work on this species, suggests that this species has behavioral flexibility because they are competent across multiple cognitive domains and are capable of reversal learning.     

扩大内需:基于“母市场效应”的理论评述

本文主要对母市场效应理论进行文献评述。描述了Krugman关于母市场效应理论的最初模型,并介绍了对母市场效应的理论拓展和实证检验,文章最后提出了在中国出口市场面临一定变化和强调扩大内需条件下对中国制造业出口的母市场效应进行实证检验的一些设想。     

组织间信任研究述评

随着组织联盟与合作的增多,组织间信任问题日益得到研究者关注。文章尝试从动、静态的角度对组织间信任的前因变量和结果变量进行梳理：单方组织层面的人口学特征及获得性特征,以及涉及双方互动层面的过去经历、目前状态及未来期望等因素会影响组织间信任的建立,降低双方合作的风险;而已经形成的组织间信任又会起到促进新知识的应用,提高联盟绩效及合作满意度的作用。今后的研究应关注组织信任的多层次分析、重视研究对象领域和地域的多样化以及互动（配对）和纵向数据的收集等。     

当前科学无神论面临的难题和专家建议

近年来,社会上许多研究科学无神论的专家学者对当前我国社会中无神论教育宣传的现状,以及比较普遍地存在的信仰缺失,而各种有神论却呈流行趋势的现象,发表了自己的看法。他们的一些认识、思考和建议,对我们进一步加强科学无神论的工作,有着重要的启发。     

荀爽与《九家易》

在荀爽与《九家易》关系问题上"荀集九家"和"九家述荀"两种观点对立。易学家尚秉和先生根据荀爽易学与《九家易》有相同的古易学说,认同前一种观点。但其理由并不充分,《九家易》不是淮南九师《易》,该书并非荀爽所集。《九家易》当成书于虞翻之后,是汉魏易学嬗变、魏晋时期象数易学与义理易学斗争的产物。研究荀爽与《九家易》的关系对于衡定荀爽易学的历史地位、把握汉魏象数易学向义理易学的演变脉络具有重要意义。     

The influence of culture on children’s immediate and delayed retrieval

Culture shapes children’s memories. However, scant attention has been given to the influence of culture on specific memory stages. Thus, we conducted two controlled experiments to examine cultural differences in memory recall at immediate and delayed retrieval phases. In Studies 1 and 2 (n = 217), 7- to 10-year-old Chinese and Euro-Canadian children watched a story involving both social- and individual-focused scenarios. Participants then recalled the story immediately afterwards (Study 1) and 5–7 days later (Studies 1 and 2). Findings reveal that Chinese children accurately reported more details from the social-focused events than did their Euro-Canadian counterparts in the immediate interview, and this result was replicated after a delay in both studies. Moreover, as expected, within-country comparisons showed that Euro-Canadian children had better memory for individual- than for social-focused events in both studies. Chinese children, however, showed better memory for social- than for individual-focused events only in the immediate interview in Study 1; their delayed retrieval was not affected by event focus. These findings reveal that cultural variations in memory are evident in both immediate and delayed retrieval. Implications for future research are discussed.     

特质愤怒对攻击行为的影响:敌意认知和冲动性水平有调节的中介作用

通过对重庆某综合大学大一到大三527名学生的问卷调查, 运用结构方程模型技术考察了特质愤怒、敌意认知、冲动性水平和攻击行为之间的关系。结果发现:(1)敌意认知在特质愤怒和攻击行为之间起部分中介的作用, 特质愤怒既对攻击行为产生直接影响, 也通过敌意认知对攻击行为产生间接影响;(2)运动冲动性因子对敌意认知的中介作用起到调节作用, 即敌意认知对攻击行为的影响随着个体冲动性水平的增加而提升;敌意认知对个体的攻击行为起着有调节的中介作用。     

哀伤研究：新的视角与理论整合

哀伤（bereavement）研究长期以来都依循“悲伤过程假设（griefworkhypothesis）”,但20世纪80年代后其强调“与逝者分离”的基本假设受到挑战,界定的模糊也使得实证研究工作难以进行。当代研究者从依恋理论、创伤研究、认知应对研究、情感的社会功能等视角多方面对哀伤领域进行深入探索并出现了一些整合性的理论模型,文中对有代表性的“依恋与哀伤双程模型”作了介绍,并对“悲伤过程假设”进行了重新检视
