Comparisons of Australians and Japanese on group-based cooperation

A cross-societal experiment with 49 Australian and 56 Japanese participants examined if the group heuristic account of ingroup-favoring behavior in a Prisoner's Dilemma game can be extended beyond the minimal group situation to a situation involving an enduring social category (i.e. participant's nationality). Participants played a Prisoner's Dilemma game five times, each time with a different partner. Two of the five partners were ingroup members, two were outgroup members, and the nationality of one partner was not known. Furthermore, one of the two ingroup (or outgroup) partners knew that the participant was a member of the same (or the other) nationality, and the other did not know it. The results indicated that the knowledge that the partner had about the nationality of the participant exerted an effect only when the partner was an ingroup member. No major difference was found between Australian and Japanese participants. An outgroup-favoring cooperation pattern was observed, but that pattern was shown to be a result of fairness concerns among Australian participants and of positive stereotypes of Australians among Japanese participants.     

The Economic, Political, Strategic, and Rhetorical Uses of Simple Constructive Dilemma in Legal Argument

The author argues that simple constructive dilemma is a valuable argument form for reasoning under relative conditions of uncertainty. When applied to legal argument this value of simple constructive dilemma is shown in its political, strategic, rhetorical, and especially economic, uses by lawyers and judges. After considering some examples of the use of the form by trial lawyers, the author gives examples of the more interesting use of the form by appellate courts. Research into the use of simple constructive dilemma by appellate courts helps us to understand how those courts distribute judicial resources. It also helps us to understand the political role of the appellate courts with respect to the doctrine of the separation of powers. Given some of the specific examples of legal reasoning used by the appellate courts presented in this article, and given the discussion of the doctrine of precedent, the article’s focus is on common law legal systems of the Anglo-American-type.     

公共物品困境中自我权力和他人权力对初中生合作行为的影响

本研究分别操纵被试稳定的权力（实验1）和不稳定的权力（实验2）,并与不同权力个体进行公共物品困境任务,以考察了自我权力和他人权力对初中生合作行为的交互作用及其权力稳定性在其中的作用。结果发现,在权力稳定情境下,高权力的初中生合作水平低于低权力组和控制组,而在权力不稳定的情境下,高权力的初中生合作水平高于低权力组。无论权力稳定与否,与低权力同伴合作时,低权力者的合作水平均显著高于与高权力同伴合作时。     

大学生在社会困境中的公平决策:社会价值取向的影响

通过两项研究考查大学生在社会困境中的行为决策及公平感体验,检验社会价值取向的影响作用,有效被试分别为85名和84名。结果表明:(1)亲社会者比亲自我者更倾向做公平决策;信息对称比不对称条件更促进被试做公平决策;女生比男生更倾向做公平决策。(2)性别在社会价值取向与信息对称性对公平决策的影响中起调节作用,社会价值取向显著影响男生的公平决策,信息对称性显著影响女生的公平决策。(3)社会价值取向显著影响个体对不公平的容忍度,亲社会者更不容忍不公平行为。(4)对于利己的不公平行为,被试都倾向接受,亲社会者并不比亲自我者体验到更强的内疚情绪;对于不利己的不公平行为,被试都倾向拒绝,且产生较强的不公平感及气愤情绪。     

论世俗道德的特点及其困境

世俗道德的产生是社会生活世俗化的必然结果,是经济发展的内在逻辑.它具有现实性、人本性和平凡性等特征.世俗道德不可避免地陷入利益主义、享乐主义和庸俗化等困境.只有"回到人本身",才能走出困境.

两难问题儿童对策行为发展的实验研究

采用实验室方法,通过两难对策任务的情景模拟,研究学生个体在自然情景下的对策行为。结果表明:(1)儿童对策行为随年龄的增长而发生变化,小学五年级是儿童对策行为发生转折的关键期,表现出较高水平的合作策略。(2)性别对对策行为的影响不显著。(3)不同类型的决策者面临同样的决策任务时,会产生不同的对策行为。     

儿童应对权威的矛盾解决策略研究

本文采用两难故事法对儿童(7～17岁)在与三种权威(父母、教师与社会上的成人)发生两难冲突时所采取的矛盾解决策略进行了研究,结果发现儿童与权威发生矛盾时所采取的解决策略存在(1)显著的对象差异,即儿童对教师更倾向接受策略,儿童对父母更倾向协商策略,儿童对社会更倾向拒绝策略;(2)显著的年龄差异,即随着年龄增长,儿童从接受权威的观点发展为坚持自己观点;(3)男女儿童,不同地区儿童应对权威的矛盾解决策不存在显著差异。     

Effects of initial choices in the prisoner's dilemma

In the two‐person prisoner's dilemma game (PDG), there is considerable evidence that the tit‐for‐tat (TFT) strategy is most effective in inducing the other person to cooperate. One of the important features of the TFT strategy is that it cooperates on the first trial. We varied the initial choices of a simulated other, and tested the effects of (a) initial choices (cooperation or defection), and (b) persistence of initial choices: unilateral cooperation (or defection) on the first trial, first two trials, or first four trials. Results showed that a cooperative strategy—one that starts with cooperative choices—induced greater cooperation than a strategy that started with defections. The results of this study clearly show that (a) a cooperative strategy—one that initiates unilateral cooperation at the outset and then adopts a TFT strategy—is very effective in inducing subsequent cooperation from the other party, (b) the effectiveness of a cooperative strategy varies directly with the cooperative orientation of the other party (a cooperative strategy is more effective against a cooperative than a competitive person), and (c) initial cooperation is more effective if it is repeated more than once.
