不对称社会困境中社会价值取向对合作的影响

以往研究表明, 社会价值取向对社会困境中合作行为变异的解释量不高。本研究指出, 初始资源配置导致个体处于某种优劣势位置上, 从而影响社会价值取向不同的个体的合作行为。研究设置了两人互动和多人互动两种情境, 通过变化被试所拥有的初始资源的相对价值或相对数量来操作优势差异, 检验亲社会者和亲自我者在社会困境中的心理与行为差异。研究结果表明, 在初始资源处于相对劣势位置时, 亲社会者比亲自我者表现出更高的合作水平。

Social Norms and Cooperation in Social Dilemmas: The Effects of Context and Feedback

Drawing from research on social norms, we proposed and tested the hypothesis that people behave more competitively in social dilemmas involving economic decisions compared to those involving noneconomic decisions. We also proposed that people would compete more if they see that others have unexpectedly competed in a prior situation and cooperate more when others have unexpectedly cooperated in a previous situation. Further, we hypothesized that if others behave consistently with expectations, such behaviors (either cooperative or competitive) would not affect subsequent behavior. One hundred ninety-five under graduate students participated in an experiment in which they made choices in two different social dilemma games. Results support the hypotheses, and the discussion addresses the implications of the study for research on social norms and decision making.     

Cooperation in Asymmetric Social Dilemmas When Equality Is Perceived as Unfair1

Three experiments examined the hypothesis that in an asymmetric social dilemma, perceived fairness of the distribution promotes cooperation. In support of the hypothesis, Studies 1 and 2 showed that willingness to voluntarily and anonymously pay for child care was related to ratings of perceived fairness of equal and equitable distributions of the quality of child care when it was a public good (provided by the municipality) or a market good (provided by a private business). Study 1 also showed that an equal distribution of the public good was perceived to be fairer than an equal distribution of the market good, whereas the reverse was true for an equitable distribution. Study 2 showed that when quality differences were explicit, an equitable distribution was perceived as fairer than an equal distribution. Study 3 showed that an equitable distribution of quantity of child care was perceived to be fairer and increased willingness to pay as compared to an equal distribution.     

Social Value Orientation,Expectations, and Cooperation in Social Dilemmas: A Meta‐analysis

Interdependent situations are pervasive in human life. In these situations, it is essential to form expectations about the others' behaviour to adapt one's own behaviour to increase mutual outcomes and avoid exploitation. Social value orientation, which describes the dispositional weights individuals attach to their own and to another person's outcome, predicts these expectations of cooperation in social dilemmas—an interdependent situation involving a conflict of interests. Yet, scientific evidence is inconclusive about the exact differences in expectations between prosocials, individualists, and competitors. The present meta‐analytic results show that, relative to proselfs (individualists and competitors), prosocials expect more cooperation from others in social dilemmas, whereas individualists and competitors do not significantly differ in their expectations. The importance of these expectations in the decision process is further highlighted by the finding that they partially mediate the well‐established relation between social value orientation and cooperative behaviour in social dilemmas. In fact, even proselfs are more likely to cooperate when they expect their partner to cooperate. Copyright © 2018 European Association of Personality Psychology     

Social Dilemmas

In social dilemma situations, each individual always receives a higher payoff for defecting than for cooperating, but all are better off if all cooperate than if all defect. Often, however, people in social dilemmas attend more to the group's payoffs than to their own, either automatically or to behave “appropriately.” But whereas social identity elicits cooperative behaviour in dilemmas, it is generally only for the benefit of an “in‐group.” Dilemmas between groups (requiring self‐sacrificial behaviour within) are often the most extreme. Consequently, the framing and manipulation of group identity is critical to cooperation rate as demonstrated by careful laboratory experimentation.     

社会价值取向与损失情境对不同时间压力下双人社会困境中合作行为的影响

为揭示双人社会困境中合作行为的影响因素,选取四种不同类型的双人社会困境,采用实验法考察社会价值取向与损失情境对不同时间压力下合作行为的影响。结果显示,亲社会个体的合作率显著高于亲自我个体的合作率,收益情境下的合作率显著高于损失情境下的合作率,在社会困境中双方冲突程度越大合作率越低;此外,高时间压力提升了亲自我个体在囚徒困境以及收益情境下信任困境中的合作率,同时降低了亲自我个体在损失情境下最大差异困境中的合作率。结果表明,社会价值取向、收益损失情境以及困境冲突程度均对合作行为的发生具有影响作用,而时间压力对合作行为的作用也同样受到三者的影响。这些发现能够为合作行为自动性的理论分歧提供新的证据。     

Intergroup and Intragroup Aspects of Leadership in Social Dilemmas: A Relational Model of Cooperation

Two experiments investigated how leadership shapes individual contributions in small groups facing public goods dilemmas. We predicted that the influence of leaders would be determined by their ability to fulfill both instrumental needs (solve the free-rider problem) and relational needs (contribute to the identity) of group members. The relative importance of these two needs was expected to vary with the salience of group membership (social vs personal identity). This hypothesis was supported in two experiments. Experiment 1 revealed that leaders showing group commitment and fairness toward members were more effective at raising contributions when social identity was salient. Furthermore, Experiment 2 showed that highly committed leaders were more influential when social identity was salient, whereas leaders with intrinsic leadership skills were more influential when personal identity was salient. This suggests that the effectiveness of leader solutions to social dilemmas depends upon the fit between leader characteristics and member expectations.     

惩罚和社会价值取向对公共物品两难中人际信任与合作行为的影响

通过两个计算机情境模拟实验, 采用“取消惩罚”范式, 引入社会价值取向变量, 发现惩罚对人际信任和合作行为具有消极影响, 具体表现为当惩罚取消后, 经历过惩罚的被试的人际信任水平显著低于无惩罚条件被试的水平。惩罚对博弈者合作行为的影响在社会价值取向不同的博弈者之间存在显著差异：经历过惩罚的亲社会型被试在惩罚取消阶段的合作程度显著低于惩罚存在阶段的合作程度, 并且显著低于无惩罚条件被试的相应水平。惩罚通过亲社会型博弈者的人际信任水平对合作程度产生间接负效应, 即惩罚程度越强, 亲社会型博弈者的人际信任水平越低, 进而使其合作程度也下降。     

Intergroup Cooperation in Common Pool Resource Dilemmas

Fundamental problems of environmental sustainability, including climate change and fisheries management, require collective action on a scale that transcends the political and cultural boundaries of the nation-state. Rational, self-interested neoclassical economic theories of human behavior predict tragedy in the absence of third party enforcement of agreements and practical difficulties that prevent privatization. Evolutionary biology offers a theory of cooperation, but more often than not in a context of discrimination against other groups. That is, in-group boundaries are necessarily defined by those excluded as members of out-groups. However, in some settings human’s exhibit behavior that is inconsistent with both rational economic and group driven cooperation of evolutionary biological theory. This paper reports the results of a non-cooperative game-theoretic exercise that models a tragedy of the commons problem in which groups of players may advance their own positions only at the expense of other groups. Students enrolled from multiple universities and assigned to different multi-university identity groups participated in experiments that repeatedly resulted in cooperative outcomes despite intergroup conflicts and expressions of group identity. We offer three possible explanations: (1) students were cooperative because they were in an academic setting; (2) students may have viewed their instructors as the out-group; or (3) the emergence of a small number of influential, ethical leaders is sufficient to ensure cooperation amongst the larger groups. From our data and analysis, we draw out lessons that may help to inform approaches for institutional design and policy negotiations, particularly in climate change management.     

Social Identification and a Solution to Social Dilemmas

The study explored whether cooperation could be promoted by identification with an in-group. A game was used to create two groups independent of each other. Thirty-six Japanese undergraduate students participated in the game, followed by a social dilemma game. Analysis revealed a two-factor structure of social identification: identification with the group and identification with its members. As predicted from social identity theory, subjects showed a significantly higher level of cooperation when the dilemma game was played with in-group members than with out-group members. Furthermore, identification with the group affected both in-group bias and cooperative behavior in the social dilemma game, but this effect was not found for identification with members.     

Cultural Values in Intergroup and Single-Group Social Dilemmas

Do cultural values influence the manner in which people cooperate with one another? This study assessed cultural characteristics of individuals and then related these characteristics to cooperative behavior in social dilemmas. Participants were assessed for their degree of vertical and horizontal individualism and collectivism, cultural values identified by Triandis (1995). They made choices in either a single-group or an intergroup social dilemma. The single-group dilemma entailed a three-person dilemma; the intergroup dilemma was identical but added subgroup competition, i.e., an opposing three-person group. The results indicated an interaction between cultural characteristics and type of dilemma for cooperation. The single-group versus intergroup effect reported by Bornstein and Ben-Yossef (1994) was replicated, but only for vertical individualists. The vertical individualists were least cooperative in the single-group dilemma but were more cooperative in the intergroup dilemma-where cooperation with the group maximized personal outcomes. The vertical collectivists were most cooperative in the single-group dilemma but were less cooperative in the intergroup dilemma- where group defection resulted in maximum group outcomes. The horizontal individualists and collectivists exhibited an intermediate level of cooperation, with no differences in cooperation between the single-group and intergroup dilemmas. Taken together, the results suggest that the relationship between cultural values and cooperation, in particular with reference to vertical and horizontal components of individualism and collectivism, is more complex than has been suggested in past research.

Disarmament Decisions as Social Dilemmas1

The individual deciding on a nuclear weapons production policy is faced with a dilemma in which a choice must be made to support one of several conflicting defense policies. In order to investigate the social-psychological variables that are related to armament policy decision making, a telephone survey was conducted in the City of St. Louis, Missouri. Adult subjects (N= 110) responded to questions concerned with cognitive, attitudinal, and emotional responses to nuclear arms. Participants were also asked to choose a weapons production policy for the United States under conditions of continued and decreased Soviet nuclear arms production. Results indicated that respondents decisions about nuclear weapons production were related to their support for deterrence, the availability of their nuclear-related images, their emotional response to nuclear war, their attributions of responsibility for the prevention of nuclear war, and their political party affiliation. Distinctions between antinuclear decision-makers and pronuclear decision-makers are discussed.     

A Social Categorization Explanation for Framing Effects in Nested Social Dilemmas

This study developed and tested the idea that social categorization processes help to explain framing effects in social dilemmas. Using self-categorization theory, we predicted that members of a collective would cooperate more when they faced homogeneous rather than heterogeneous resource frames. We manipulated the starting point of resources for the members of each of two subgroups making up a larger collective in a nested social dilemma. The resources of the subject's own subgroup started at the individual, subgroup, or collective level, and the resources of the opposing subgroup also started at the individual, subgroup, or collective level. The condition in which both subgroups' resources began at the collective level was similar to a traditional commons dilemma, while the condition in which both subgroups' resources began at the individual level was similar to a traditional public goods problem. The other conditions were new to this research domain. We found higher allocations to the collective account when the initial resource location was the same for both subgroups (versus different for each subgroup), even when this initial location was the subgroup or individual level. Whereas previous explanations for framing effects cannot account for these results, social categorization processes provide a parsimonious explanation for the observed pattern of allocations.     

社会困境问题的理论架构与实验研究

社会困境是指个体理性导致集体非理性这样的情境。社会困境研究的推进要求一个新的框架来理解已有理论, 这一框架将这些理论区分为宏观、中观和微观三个层面。实验研究依据这些不同层面的理论, 以实验游戏为工具来探讨人们在面临社会困境时做出选择的心理机制及其影响因素, 从而对社会困境问题发展出相应的问题解决路径。理论的发展、实验任务本身的改进以及研究的外在效度预示了通过实验方法来研究社会困境问题有着广阔的前景。     

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     

Effects of Environmental Uncertainty and Social Value Orientation in Resource Dilemmas

This study investigated the relationship between environmental uncertainty and social value orientation in a replenishable resource dilemma paradigm. One hundred seventy-two undergraduates harvested units from a common resource pool over 20 trials. Two levels of social value orientation (cooperative, noncooperative) were crossed with two levels of replenishment rate uncertainty (low, high). As predicted, noncooperators harvested significantly more resources than cooperators and high uncertainty subjects harvested more resources than low uncertainty subjects. The primary finding was the hypothesized three-way interaction among social value orientation, environmental uncertainty, and trials: Social value orientation moderated harvest decisionsonlyunder conditions of high uncertainty during the middle series of harvest trials. Noncooperators increased their harvests during this period, while cooperators harvested less and held their harvests constant across these trials. These results demonstrate that systematic individual differences exist in decision makers' responses to high environmental uncertainty. We suggest that social value orientation may exert its effect by influencing the scanning and processing of goal-relevant cues in this decision environment.     

Understanding and Treating Social Phobia

Social phobia, a relatively obscure disorder, is receiving increased attention due to evidence suggesting that it is more prevalent and debilitative than once thought. The purpose of this article is to help counselors better understand the nature of and treatments for this disorder. Effective behavioral and pharmacological approaches are reviewed, and counseling implications are discussed to increase counselors' confidence in providing treatment to people with social phobia.
