Effects of trait anger and anger expression style on competitive attack responses in a wartime prisoner’s dilemma game

We assessed the role of trait anger and anger expression style on competitive/aggressive decision making and responding. In a 100‐trial iterated Prisoner’s Dilemma (IPD), with instructions to simulate wartime interactions, competition/aggression was defined as “attacking the opponent,” and “waiting for troop reinforcements” was the noncompetitive alternative response. Prior to play, 92 university student players completed the State‐Trait Anger Expression Inventory. They were then paired to play the IPD against partners of similar or dissimilar trait anger levels. At postplay, the State Anger scale was readministered. Results showed significant preplay to postplay increases in state anger, with greater increases shown by high trait anger players. Thus, high trait anger players were especially subject to arousal. Players in the high trait anger group made more competitive/attack responses, and they were more likely to do so when paired with a high trait anger partner. As a result of the high level of competitive/aggressive play, both groups ended with a negative troop count. Trait anger as a general personality temperament was predictive of state anger, competitive/attack responses, and the number of trials before a retaliation was made. The expressive style of anger‐control was also related to manner of play. Trait anger had strong direct and indirect effects through anger control on the number of competitive attack responses. It was concluded that trait anger, especially trait anger/temperament, and anger control difficulties may be toxic personality factors in decision making and competitive behavior. Aggr.

Exchanges of group-based favours: Ingroup bias in the prisoner's dilemma game with minimal groups in Japan and New Zealand

Japanese ( N  = 48) and New Zealander ( N  = 55) participants were first assigned to one of two minimal groups, and then played a prisoner's dilemma game twice with an ingroup member and twice with an outgroup member. In one of the two games they played with an ingroup (or outgroup) member, participants and their partner knew one another's group memberships (mutual-knowledge condition). In the unilateral-knowledge condition, only the participants knew the group membership of their partner, but the partner did not know the group membership of the participant. Ingroup bias in cooperation emerged only in the mutual-knowledge condition in both countries; in the unilateral-knowledge condition no ingroup bias emerged. Mediational analyses found that, in accord with predictions, cooperation in the mutual-knowledge condition is mediated by expectation of the partner's cooperation. Ingroup bias in the mutual-knowledge condition emerged only among those who identified with the ingroup. Results provide support for a group heuristics account of ingroup favouritism in the minimal group. According to this account, participants who face minimal groups activate an ecologically adaptive heuristic of unilaterally cooperating with members of the same group, expecting indirect repayment from others in the same group.     

Infant feeding and HIV in Sub-Saharan Africa: what lies beneath the dilemma?

The debate over how to best guide HIV-infected mothers in resource-poor settings on infant feeding is more than two decades old. Globally, breastfeeding is responsible for approximately 300,000 HIV infections per year, while at the same time, UNICEF estimates that not breastfeeding (formula feeding with contaminated water) is responsible for 1.5 million child deaths per year. The largest burden of these infections and deaths occur in Sub-Saharan Africa. Using this region as an example of the burden faced more generally in other resource-poor settings, we contrast the evolution of the clinical standard of care for infant feeding with HIV-infected mothers in high-income countries to the current international clinical guidelines for HIV-infected mothers and infant feeding in resource-poor settings. While the international guidelines of exclusive breastfeeding for a 6-month period seem to offer the least-worst strategy for reducing mother-to-child transmission of HIV during infancy while conferring some immunity through breastfeeding post-6 months, we argue that the impact of the policy on mothers and healthcare workers on the ground is not well understood. The harm reduction approach on the level of health policy translates into a complicated, painful moral dilemma for HIV-positive mothers and those offering them guidance on infant feeding. We argue that the underlying socio-economic disparities that continue to fuel the need for a harm reduction policy on infant feeding and the harm to women and children justify: (1) that higher priority be given to solving the infant feeding dilemma with improved data on safe feeding alternatives, and (2) support of innovative, community-driven solutions that address the particular economic and cultural challenges that continue to result in HIV-transmission to children within these communities.

公共物品困境中的突显身份效应及合作动机对合作行为影响

从合作动机的激发与破坏的角度探讨公共物品困境中突显身份对合作行为的影响,同时考察社会价值取向与突显身份之间的关系。结果表明：突显合作者与突显不合作者两种方式都会提高被试的合作水平;两种突显方式的作用机制不同。突显合作者条件下,被试的合作行为受内在动机和外在动机的共同影响。而突显不合作者则会破坏被试合作的内在动机,外在动机对提高合作行为起主要作用;突显合作者条件下,合作取向的被试更多受内在动机的影响,而非合作取向的被试则更多受外在动机的影响。在突显不合作者的条件下,合作取向和非合作取向被试的合作行为都受外在动机的影响较大。     

公共资源两难管理的社会学习过程和动机释放机制

公共资源两难的根本问题是个人经济利益与社会整体利益的矛盾。一些人为了追逐个人利益最大,过度获取公共资源,走向＂公共的悲剧＂,或不愿为公共资源作出贡献,＂搭便车＂现象流行。传统的研究从理性经济人的角度探讨公共资源两难博弈行为的机制,用＂贪婪＂来解释＂搭便车＂现象,并根据强化理论以奖励和惩罚作为主要对策。但是,这种理性经济人观点忽视了人的社会动机。实际上,公共资源两难博弈是一个社会互动的过程,人的社会心理因素在其中起了很重要的作用,因此在方法论上有必要从社会人（Homo socius）的人性观来进行分析。本文在当前的相关研究文献基础上,分析了公共资源两难博弈行为的动机模式,从社会学习理论出发,提出了公共资源两难管理的社会学习过程和动机释放机制。     

Intercultural Model of Ethical Decision Making: Addressing Worldview Dilemmas in School Counseling

The role of school counselors has expanded and deepened over the past few decades, just as the K–12 student population has become more diversified. Professional school counselors regularly encounter ethical dilemmas related to the intersection of their transformed role and students' needs. School counselors, therefore, need assistance and support to develop the skills and problem‐solving strategies to effectively, ethically, and respectfully negotiate these dilemmas. The authors propose the Intercultural Model of Ethical Decision Making as a practical, user‐friendly tool to help school counselors meet these complex challenges.     

The issue of human existence as represented in dreaming: A new Daseinsanalytic interpretation of the meaning of dreams

Abstract

Dreams are associated with those issues of our waking life which preoccupy us emotionally. According to our Daseinsanalytic view, however, the issue that concerns us while dreaming is actually not the concrete worrying matter itself, but its existential dimension. This view is based on Martin Heidegger's concept of human being as that being to which its own being is an issue. It means that all feeling and understanding dealing with concrete issues concurrently refer to fundamental issues of our existence. Dreaming though, we are focused entirely on the fundamental aspects. Dreams show the very individual and specific struggle of the dreamer with certain conditions of human life, which he or she is unable or unwilling to accept because they seem too difficult to endure. I want to demonstrate this method of interpretation on a dream of a depressive patient. The example illustrates that the concerns of dreaming are rooted in and refer to an existential dilemma that is hidden in the concrete difficulties of waking life and represented in the concrete dream events. In addition, it gives us the opportunity to inquire into the specificity of the fundamental dilemma of a personality with a “depressive view” of the world.     

Between the Horns: A Dilemma in the Interpretation of the Running of the Bulls – Part 1: The Confrontation

The essay, divided in two parts, examines the event of the running of the bulls (encierro in Spanish). The phenomenon of the encierro, a complex cultural activity of deep historical roots, demands to be understood: What drives people to risk injury or death at the horns of untamed bulls? How should we make sense of this, subjective and objectively? To answer these questions, I use a framework that relies on explanation and assessment of popular views on the way to arguing for a philosophical alternative. This arrangement is readily adaptable to many other sporting (and non-sporting) activities where risk and/or mass participation are key factors. Its unorthodox format – organised around an opening narrative of a paradigmatic, skilled and lucky run with the bulls, as well as hors texte (direct appeals to the reader) – brings the reader straight into the fray, philosophical and otherwise. Part I begins by presenting the history of the encierro. It also explains the dynamics of the event, often via images with pedagogical and critical side-commentaries. It proceeds to introduce and critically engage with prevalent explanations, most with ethnological tendencies, that conceive the running as tradition, rite, ritual and sport. This part ends with a dilemma whereby we either try to explain matters by resorting to particular and partial interpretations, or a ‘democratic’ conglomerate of superficial and confusing boundaries, or in the end we simply concede our inability to understand the phenomenon of the running of the bulls in toto. This philosophical impasse will be evaded in part 2 (Sport, Ethics and Philosophy 2, 1) via existentialist and phenomenological analysis.
