Forum: A New Culture of Learning

These brief essays by Mary Hess, Eugene Gallagher, and Katherine Turpin are solicited responses from three different contexts to the provocative book by Douglas Thomas and John Seely Brown, The New Culture of Learning (2011). Mary Hess writes from a seminary context, providing a critical summary of the authors' major concepts and their ramifications, positive and negative, for theological education and the church. Eugene Gallagher writes from a liberal arts setting, identifying characteristics of the face‐to‐face classroom that would go missing in a careless adoption of online learning environments. Finally, Katherine Turpin reports from the classroom, chronicling her experience in a course she redesigned for a graduate theological setting to employ some of the authors' pedagogical principles and strategies. Together, these responses offer critical appreciation and constructive critique of the work Thomas and Seely Brown have done – and point the conversation forward.     

金钱概念对消费者独特性需求的影响研究

本研究探讨了金钱概念对消费者独特性需求的影响。通过三个实验,实验1研究表明启动金钱概念的消费者在进行产品选择时反从众需求更强烈;实验2研究表明金钱的丰富程度会调节金钱概念对消费者创新性选择的影响,金钱富有启动组选择独特性产品的比例要显著高于金钱缺乏启动组和控制组;实验3研究表明金钱概念对消费者独特性需求的影响是通过社交距离的中介作用完成的,启动金钱概念的消费者会感知到更远的社交距离,进而产生更强烈的独特性需求。     

异性交友决策任务上为不同心理距离他人决策的风险偏好

使用中国文化背景下修订的Beisswanger等人的异性交友决策问卷, 采用2种方法操纵自我-他人心理距离, 考察了男女大学生在后果严重性不同的异性交友决策任务上为不同心理距离他人决策风险偏好的差异。实验1发现, 被试为具体和笼统他人决策时的风险偏好无显著差异, 在后果不严重任务上比后果严重任务上更冒险, 男性比女性更冒险。心理距离与决策者性别的交互作用显著：男性为具体他人决策更冒险, 而女性为笼统他人决策更冒险。实验2发现, 被试为不相似他人比为相似他人决策更冒险, 在后果不严重任务上比在后果严重任务上更冒险, 男性比女性更冒险。后果严重性与决策者性别交互作用显著：男性在后果严重和不严重任务上的风险偏好无显著差异, 而女性在后果不严重任务上比后果严重任务上更冒险。综合两个实验的结果, 可以得出以下结论：相对于具体和笼统他人的区分而言, 相似和不相似他人的区分是一种更加稳定和有效的区分自我-他人心理距离的方法。结合相关研究及理论对结果进行了讨论。     

Lessons from a Faraway land: The effect of spatial distance on creative cognition

Recent research [Förster, J., Friedman, R. S., & Liberman, N. (2004). Temporal construal effects on abstract and concrete thinking: Consequences for insight and creative cognition. Journal of Personality and Social Psychology, 87, 177-189] has identified temporal distance as a situational moderator of creativity. According to Construal Level Theory [Liberman, N., Trope, Y., & Stephan, E. (2007). Psychological Distance. In E. T. Higgins & A. W. Kruglanski (Eds.), Social psychology: A handbook of basic principles (pp. 353-381). New York: Guilford Press], temporal distance is just one case of the broader construct of psychological distance. In the present research, we investigated the effect of another dimension of psychological distance, namely, spatial distance, on creative cognition and insight problem solving. In two studies, we demonstrate that when the creative task is portrayed as originating from a far rather than close location, participants provide more creative responses (Study 1) and perform better on a problem solving task that requires creative insight (Study 2). Both theoretical and practical implications of this finding are discussed.     

The Distance Function in Commutative ℓ-semigroups and the Equivalence in Łukasiewicz Logic

The equivalence connective in ukasiewicz logic has its algebraic counterpart which is the distance function d(x,y) =|x–y| of a positive cone of a commutative -group. We make some observations on logically motivated algebraic structures involving the distance function.     

Ponzo错觉解释的合理性：倾斜恒常性理论的局限

倾斜恒常性理论是一种新的解释Ponzo错觉的理论,但是似乎存在一些局限。本研究采用调节法通过两个实验考察了四种Ponzo错觉版本在各种条件(视角和水平线段间距)下的错觉量情况,以此来检验倾斜恒常性理论。实验一中,对称Ponzo错觉变异版本在50mm时的错觉量情况和Prinzmetal(2001)的结果相似,但是在85mm和120mm时得到了较多的错觉量,这和倾斜恒常性理论的理论预期不符。实验二对不对称Ponzo错觉的考察得到了和实验一类似的结果,只有50mm时的情形符合倾斜恒常性理论预期。通过以上实验得到水平线间距和视角因素都是产生Ponzo错觉的重要因素,而倾斜恒常性理论过分强调了背景线的倾斜诱导效应,忽略了其他结构因素对Ponzo错觉的影响,所以倾斜恒常性理论具有一定的局限性,不能有效地解释Ponzo错觉的产生机制。     

心理距离与决策者角色对风险决策的影响

采用改编的I0S量表测量自我与他人的心理距离,在收益和损失情境下,综合探讨了为他人和预测他人决策时心理距离对个体风险偏好的影响.结果发现:(1)与他人心理距离越远,个体决策时越偏好风险,且反应时越短;(2)个体预测他人决策时比为他人决策时更偏好风险,但两者反应时没有显著差异;(3)心理距离与决策者角色存在交互作用,即预测时个体认为远心理距离他人比近心理距离他人更冒险,而为他人决策时两者差异消失;(4)决策角色与决策框架、心理距离与决策框架存在交互作用:在收益框架下,自我他人心理距离较远时个体更偏好风险,且个体预测比为他人决策时更冒险,损失条件下无差异.依据相关理论对这些结果进行了分析讨论.     

Giving from a distance: Putting the charitable organization at the center of the donation appeal

Past research has shown repeatedly that people prefer donating to a single identified human victim rather than to unidentified or abstract donation targets. In the current research we show results countering the identifiable victim effect, wherein people prefer to donate to charitable organizations rather than to an identifiable victim. In a series of five studies, we manipulate temporal and social distance, examine a variety of donation targets, and measure intention to donate time or money as well as actual donations of money. We show that people are more willing to donate to a charitable organization when they are temporally or socially distant from the population in need. Willingness to donate to a specific person in need is higher when donors are temporally or socially close to the donation target. Furthermore, we demonstrate that (a) empathy mediates donations to a single victim, yet does not mediate donations to charitable organizations; (b) that donation giving to charitable organizations is unique and is not similar to donations to a group of victims. Theoretical and practical implications are discussed.     

Nie Wieder: Group‐Based Emotions for In‐Group Wrongdoing Affect Attitudes toward Unrelated Minorities

This article focuses on the effects of group‐based emotions for in‐group wrongdoing on attitudes towards seemingly unrelated groups. Two forms of shame are distinguished from one another and from guilt and linked to positive and negative attitudes towards an unrelated minority. In Study 1 (N = 203), Germans' feelings of moral shame—arising from the belief that the in‐group's Nazi past violates an important moral value—are associated with increased support for Turks living in Germany. Image shame—arising from a threatened social image—is associated with increased social distance. In Study 2 (N = 301), Britons' emotions regarding atrocities committed by in‐group members during the war in Iraq have similar links with attitudes towards Pakistani immigrants. We extend the findings of Study 1 by demonstrating that the effects are mediated by a sense of moral obligation and observed more strongly when the unrelated group is perceived as similar to the harmed group. Guilt was unrelated to any outcome variable across both studies. Theoretical and practical implications about the nature of group‐based emotions and their potential for affecting wider intergroup relations are discussed.
