A Cognitive Model of Dynamic Cooperation With Varied Interdependency Information

We analyze the dynamics of repeated interaction of two players in the Prisoner's Dilemma (PD) under various levels of interdependency information and propose an instance‐based learning cognitive model (IBL‐PD) to explain how cooperation emerges over time. Six hypotheses are tested regarding how a player accounts for an opponent's outcomes: the selfish hypothesis suggests ignoring information about the opponent and utilizing only the player's own outcomes; the extreme fairness hypothesis weighs the player's own and the opponent's outcomes equally; the moderate fairness hypothesis weighs the opponent's outcomes less than the player's own outcomes to various extents; the linear increasing hypothesis increasingly weighs the opponent's outcomes at a constant rate with repeated interactions; the hyperbolic discounting hypothesis increasingly and nonlinearly weighs the opponent's outcomes over time; and the dynamic expectations hypothesis dynamically adjusts the weight a player gives to the opponent's outcomes, according to the gap between the expected and the actual outcomes in each interaction. When players lack explicit feedback about their opponent's choices and outcomes, results are consistent with the selfish hypothesis; however, when this information is made explicit, the best predictions result from the dynamic expectations hypothesis.     

MEDICAL MANAGEMENT OF INFANT INTERSEX: THE JURIDICO‐ETHICAL DILEMMA OF CONTEMPORARY ISLAMIC LEGAL RESPONSE

Technological advances in the field of medicine and health sciences not only manipulate the normal human body and sex but also provide for surgical and hormonal management of hermaphroditism (intersexuality). Consequently, sex assignment surgery has not only become a standard care for babies born with genital abnormalities in the West but even in some Muslim states. On the positive side, it goes a long way in saving children born with abnormal genitalia from numerous legal interdictions of the pre‐sex corrective surgery. Nevertheless, the larger ethical and legal questions that medical management of genital abnormality raises to some extent have not been adequately appreciated by contemporary Muslim responses. This article, therefore, in principle argues against surgical management of intersexuality during early infancy from the Islamic legal perspective.     

Moral Dilemmas in Military Situations: Proportionality Principle,Religiosity, Political Attitudes,and Authoritarian Personality

The current study focuses on a moral dilemma in military situations: the amount of force to be used in order to neutralize a “most wanted” terrorist. This study examines the association between this moral dilemma with 4 independent variables: agreement with the proportionality principle (mediating variable), level of religiosity, authoritarian personality, and political attitudes. Three equal groups of participants (together, N = 357) were included: Israeli regular army combat soldiers, Israeli reserve combat soldiers, and Israeli students. In accordance with the study hypotheses, the 4 independent variables significantly correlated with each other and with moral decisions. Structural equation modeling indicated that agreement with the proportionality principle is the best predictor of moral decision, and mediated the association between level of religiosity and political attitudes and moral decisions.     

Accuracy in discrimination of self-reported cooperators using static facial information

People readily ascribe personality traits to others and believe that faces hold important guides to character. Here we examined the relationship between static facial appearance and self-reported cooperation/defection using the prisoner’s dilemma (N = 193). Study 1 combined face images of those self-reporting they would be most and least likely to cooperate. The composites of cooperators were seen as more cooperative than non-cooperators. Study 2 demonstrated accuracy with ratings of individual faces. Masculinity of face shape was negatively related to self-reported cooperation for men, but not women. Further, ratings of smile intensity were positively, but not significantly, related to self-reported cooperation. Overall, individuals appear able judge the potential of others to cooperate from static facial appearance alone at rates greater than chance.     

Legal realisms: on law and politics

The focus of this work is the issue of whether, and to what extent, the nature of the law is affected by politics, has been taken up by the American and Scandinavian legal realists. By the very fact of their being products of␣the socio-political conditions of the most recent century, the American and Scandinavian legal realisms are the movements that have most explicitly and systematically brought to the surface one particular characteristic phenomenon of contemporary Western legal systems: the existence of two basic forces simultaneously attracting and repelling, affecting the law in its relations with the political world.I would like to deeply thank Brian Bix, Laura Carlson, Roger Cotterrell and Jori Munukka for their many helpful comments on earlier drafts of this article.

基因治疗伦理困境的反思

基因治疗技术作为人类在生命科学领域取得的重大突破,给社会的伦理道德带来了巨大的冲击。通过对这些伦理困境成因的分析和反思,指出有些伦理困境从严格意义上说并不是真正的困境,这些困境会随着基因科技的发展和我们对基因科技的合理应用而解决。     

模糊道德事件中权威对儿童道德推理影响的研究

研究使用模糊道德事件来研究儿童权威概念对其道德判断的影响,并初步探讨了权威的个人特征对儿童的道德判断的影响.结果表明,使用模糊道德事件的研究材料能诱发儿童根据故事情境中的权威观点来进行判断;模糊道德事件判断结果表明儿童的独立道德判断立场会因为较高级别权威(校长和教师)的相反观点而改变,但很少会因为低权威或无权威者(班长与普通同学)的相反观点而改变.     

动态两难对策中信息反馈方式对合作行为的影响

本研究着重探讨了多人动态对策情景中信息反馈方式和群体认同度对合作行为变化的影响。结果表明,集体反馈比个人反馈更能促进被试的合作行为,而群体认同度对合作行为的影响不显著;在集体反馈条件下,合作行为在各轮次问的随机波动较大,但在三个决策阶段问较为稳定;个人反馈条件下,合作行为在各轮次问的随机波动较小,但在三阶段问呈现出不对称的“U”型变化趋势。研究认为,建立在反馈信息基础上的决策学习使合作行为的动态变化具有策略性和适应性。     

The Empathic Foundations of Security Dilemma De‐escalation

Security dilemma theorists have long recognized the importance of empathy to the de‐escalation of conflict between actors caught in security dilemma dynamics, but they have left empathy undertheorized and have neglected to recognize its deeply contested nature. This article responds to this omission by bringing multidisciplinary literature on empathy to bear on security dilemma thinking. Contrary to some contemporary empathy research that draws attention to its automatic, unconscious, and intuitive properties, the article highlights the deliberate, effortful, and reflexive capacity to empathize across complex social contexts such as security dilemma dynamics. It shows how empathy of this kind can lead actors to moderate their positions on key issues at the heart of a conflict, reinterpret their interests, and broaden the zone of possible agreement between themselves and an adversary. The article demonstrates these notions empirically by locating empathy within the de‐escalation of tensions between the United States and Iran between 2009 and 2016. Drawing on primary interview material with former U.S. officials, the argument is made that the development of specific empathic capacities by key U.S. officials played an important and unrecognized role in the de‐escalation of security dilemma dynamics between the United States and Iran.     

一种齐当别思想下的量子决策模型：对囚徒困境中的分离效应的解释

量子决策模型是近10年来提出的一种新型决策模型, 用以解释那些违背经典决策模型的现象。虽然当前的量子决策模型能够解释囚徒困境中的分离效应, 但其中却存在一些困难, 即会产生反常的概率关系以及无法精确拟合分离效应量较大的实验结果。本研究在分析当前量子决策模型困难的基础上, 结合齐当别思想对模型进行改进和优化。结果表明, 研究所构建的量子决策模型克服了当前模型中的困难, 并且能够预测囚徒困境博弈中由他人收益差距改变而引起的分离效应变化趋势。本研究还是一次启发式决策模型与计算式决策模型相结合的探索。
