实验社会心理学中的社会困境

社会困境是指个体理性会导致集体非理性这样的情境。大量实证研究考察社会困境中合作行为的机制,然而缺乏系统的理论框架。实验室研究中所用的社会困境可以从4个方面来分类：“给-游戏”与“拿-游戏”、两人困境与多人困境、对称与非对称困境以及重复与非重复困境。综合而言,以往实验研究主要从个体差异、任务结构以及知觉与策略等3个方面考察影响社会困境的因素,这些影响因素可以整合在一个概念框架中。未来的研究尚需要联合多个学科,澄清研究变量之间的关系,并继续丰富相关概念和理论

Implicit racial bias and epistemic pessimism

Implicit bias results from living in a society structured by race. Tamar Gendler has drawn attention to several epistemic costs of implicit bias and concludes that paying some costs is unavoidable. In this paper, we reconstruct Gendler’s argument and argue that the epistemic costs she highlights can be avoided. Though epistemic agents encode discriminatory information from the environment, not all encoded information is activated. Agents can construct local epistemic environments that do not activate biasing representations, effectively avoiding the consequences of activation. We conclude that changing our local environments provides a way to avoid paying implicit bias’s epistemic costs.     

The use of moral dilemmas for teaching agricultural engineers

Agricultural engineers’ jobs are especially related to sustainability and earth life issues. They usually work with plants or animals, and the aim of their work is often linked to producing food to allow people to improve their quality of life. Taking into account this dual function, the moral requirements of their day-to-day professional practice are arguably greater than those of other professions. Agricultural engineers can develop their ability to live up to this professional responsibility by receiving ethical training during their university studies, not only by taking courses specifically devoted to ethics, but also by having to deal with moral questions that are integrated into their technical courses through a program of Ethics Across the Curriculum (EAC). The authors feel that a suitable pedagogical technique for achieving this goal is the use of moral dilemmas, following Kohlberg’s theory of levels of morality (1981), with the final objective of attaining a post-conventional level. This paper examines the possibilities and limitations of using moral dilemmas as a pedagogical technique for training agricultural engineers. The cases, discussions, and evaluation used in the Agricultural Engineering Department of the Technical University of Valencia (Spain) are also presented. An earlier version of this paper was presented at the 2005 conference, Ethics and Social Responsibility in Engineering and Technology, Linking Workplace Ethics and Education, co-hosted by Gonzaga University and Loyola Marymount University, Los Angeles, CA, USA, 9–10 June 2005.     

Development of clinical vignettes to assess healthcare decision-making capacity in elderly with mild cognitive impairment and Alzheimer's disease

IntroductionCognitive impairment can constrict healthcare decision-making capacity, as it affects the ability to understand, appreciate, and reason with information, as well as communication abilities. Therefore, decision-making capacity of elders with mild cognitive impairment or Alzheimer's disease should be carefully assessed when patients are asked to make decisions regarding their health. Vignettes are particularly relevant to assess healthcare decision capacity, since they can come close to real life situations and improve statistical reliability of capacity assessment instruments.ObjectiveThis paper describes the construction and development process of three hypothetical vignettes, to be included in a new Portuguese assessment tool of healthcare decision-making capacity (CAI-Health).MethodFor vignettes’ development, examples from other assessment tools were first reviewed to summarize their text length, language complexity and health information contained. Most prevalent causes of mortality and morbidity in Portuguese elders were then identified, in order to select the health issues to include in CAI-Health’ vignettes. Seven vignettes were developed, and three were selected to be included in CAI-Health. After vignette's selection, these were reviewed by three experienced medical experts, during a focus group.ConclusionVignettes final version include cases of increased complexity, presenting situations of mild cognitive impairment, lung tumor and knee arthrosis.     

The Campbell Paradigm as a Conceptual Alternative to the Expectation of Hypocrisy in Contemporary Attitude Research

Hypocrisy—professing a general attitude without implementing corresponding attitude-relevant behavior—is, according to Ajzen and Fishbein (2005), commonly found in attitude research that aims to explain individual behavior. We conducted two studies that adopted the Campbell paradigm, an alternative to the traditional understanding of attitudes. In a laboratory experiment, we found that specific attitude-relevant cooperation in a social dilemma was a function of people’s pre-existing general environmental attitude. In a quasi-experiment, we corroborated the reverse as well; engagement in attitude-relevant dietary practices was indicative of environmental attitude. When using Campbellian attitude measures, there is no room for hypocrisy: People put their general attitudes into specific attitude-relevant practices, and differences in people’s general attitudes can be derived from their attitude-relevant behavior.     

Priming Effects on Cooperative Behavior in Social Dilemmas: Considering the Prime and the Person

We test whether people with a relatively more intrinsic vs. extrinsic value orientation (RIEVO) are particularly likely to enact cooperative behavior in resource dilemmas when they are primed with relatedness goals. In Study 1, high RIEVO participants primed with relatedness exhibited more restrained fishing behavior in a resource dilemma than their unprimed counterparts or participants low in RIEVO. Study 2 replicated this effect and further showed that the prime must signal the possibility of satisfying a valued goal (relatedness satisfaction) in order to elicit the value-consistent behavior. We discuss these results in the context of recent process models of goal priming, and also discuss how these findings contribute to our understanding of cooperative behavior and the predictive power of value constructs more broadly.     

Dilemmas of Practice: Challenges to Program Quality Encountered by Youth Program Leaders

To create and sustain high quality youth development programs it is important to understand the challenging situations and dilemmas that emerge in program leaders’ daily work with youth. In this research the experiences of leaders in 12 programs were followed over a 2–9 month period, which led to the identification of 250 dilemma situations. Qualitative analyses identified 5 categories and 12 subcategories of dilemmas that reflected distinct types of considerations (e.g., youth’s personalities, relationships with the community). The analyses also found that the experienced leaders in the study typically responded to these dilemmas in ways that were youth-centered and that balanced multiple considerations. It is argued that researchers need to go beyond identifying features of high quality programs, and more fully examine how effective leaders create and sustain high quality in response to the challenging situations of practice.     

“Seeing is believing”: The effects of facial expressions of emotion and verbal communication in social dilemmas

In social dilemmas, verbal communication of one's intentions is an important factor in increasing cooperation. In addition to verbal communication of one's intentions, also the communication of emotions of anger and happiness can influence cooperative behavior. In the present paper, we argue that facial expressions of emotion moderate verbal communication in social dilemmas. More specifically, three experiments showed that if the other person displayed happiness he or she was perceived as honest, trustworthy, and reliable, and cooperation was increased when verbal communication was cooperative rather than self‐interested. However, if the other person displayed anger, verbal communication did not influence people's decision behavior. Results also showed interactive effects on people's perceptions of trustworthiness, which partially mediated decision behavior. These findings suggest that emotion displays have an important function in organizational settings because they are able to influence social interactions and cooperative behavior.

The effects of interpersonal relationship and character gender on adolescents' resolutions of moral dilemmas

An experimental study using two forms of the Defining Issues Test [Rest, J. R. (1979). Revised manual for the Defining Issues Test. Minneapolis: Moral Research Project, University of Minnesota.], modified to present either a high degree of relationship among characters or a low degree of relationship among characters, was conducted with 114 college students. The gender of the characters in the dilemmas was also systematically varied. Both male and female students evidenced principled (Stages 5 and 6) reasoning more often when dilemma characters were male than when story characters were female. Participant gender and relationship condition were significant factors in the frequency of Stage 4 reasoning. Male students in the low-relationship condition evidenced Stage 4 (“Law and order”) reasoning most often when story characters were male, while male students, like female students in all conditions, showed Stage 4 reasoning more often when female characters were presented in the high-relationship condition. The degree to which moral decisions were supportive of an affected character revealed more support when story characters were female than when they were male. Results indicate that even in hypothetical situations, moral judgments vary with the gender of the person being judged and to some degree with the relationships among those involved in the dilemma. These findings are consistent with a view that multiple, equally valid approaches to moral judgment might exist and affect the development of male and female students differently.
