“追名弃利”：权力动机与社会存在对亲社会行为的影响

目前关于权力动机的研究主要关注权力动机的阴暗面, 但是对权力动机的积极面尚不清楚。本研究从公平与合作行为的角度出发, 分别采用最后通牒博弈和公共物品博弈任务, 探讨不同权力动机水平个体在内隐(眼睛线索)或外显(他人在场)社会存在下的亲社会行为是否不同。结果发现, 在眼睛线索或他人在场条件下, 相对于低权力动机者, 高权力动机者表现出更高的公平与合作水平。然而当没有社会存在线索时, 高低权力动机者的亲社会行为没有显著差异。结果提示高权力动机者出于名誉和地位的策略考虑, 也会表现出积极的亲社会行为。     

社会困境中合作行为的阶层差异：自我与他人的双重视角

为了探究个体自身与他人的社会阶层对个体在社会困境中合作行为的影响及其作用机制,本研究通过问卷和实验研究来考察自身阶层的行为效应、互动对象阶层的调节效应以及信任有中介的调节作用。研究发现：（1）低阶层者倾向于比高阶层者表现出更多的合作行为;（2）感知到的互动对象阶层对不同阶层个体的合作行为存在显著的调节效应;（3）个体对互动对象的信任水平（即对他人合作行为的预期）对此调节效应起到中介作用。     

欺骗判断与欺骗行为中自我控制的影响

欺骗判断与欺骗行为有着不同的心理机制, 正确认识二者之间的关系有助于增强人际间的信任和团队的长远利益。采用行为学实验从两种视角下考察自我控制对欺骗的影响。实验1采用材料评定的方法考察了识别他人自我控制能力状况对欺骗判断的影响, 结果发现对比高自我控制能力的人, 被试更倾向于认为低自我控制能力的人更有可能为了自己的利益产生欺骗行为和欺骗倾向。实验2采用颜色Stroop任务考察了识别他人自我控制资源衰竭状况对欺骗判断的影响, 结果发现当识别他人自我控制资源衰竭时, 在评价他人为自己利益去欺骗、为他人利益去欺骗以及在特定情境中欺骗倾向上, 没有发现任何显著的主效应或交互作用。实验3采用视觉−感知任务来考察不同水平的自我控制能力对欺骗行为的影响, 结果发现, 对比高自我控制组, 低自我控制组有更多的欺骗行为和欺骗倾向。实验4采用颜色Stroop任务和视觉−感知任务来考察自我控制资源对欺骗行为的影响, 结果发现, 对比控制组, 自我控制资源衰竭组有更多的欺骗行为和欺骗倾向。这些研究结果表明, 在进行欺骗判断时, 相比自我控制资源状况, 个体会优先识别他人的自我控制能力水平来判断其是否具有欺骗动机或欺骗倾向。在欺骗行为中, 高自我控制能力的个体, 能够更好地抑制自私动机, 更多的考虑长远利益, 出于自身利益去欺骗的可能性会更小; 自我控制资源充足的个体, 更有可能会经得住诱惑, 自私自利的欺骗行为发生的可能性也会更小。     

个体对他人的权力感知与情绪体验

他人不同的权力水平会引发个体不同的权力感知,带来不同的情绪体验。以往关于权力与情绪的研究多关注的是个体自身作为权力目标时的情况,而研究通过两个实验来探究个体对他人的权力感知与情绪体验之间的关系。实验一采用回忆法,从情绪效价和趋近/回避动机的角度分析个体唤起的情绪反应,发现个体在与不同水平的权力目标交互过程中均表现出了明显的混合情绪,且相比于远距离的高权力目标,个体与近距离的权力目标进行交互时容易产生更多的积极情绪和趋近动机倾向; 实验二通过观看视频的方式启动被试的混合情绪,发现以积极情绪为主的混合情绪的唤起会影响个体对他人的权力感知,具体表现为对一定社会距离内的权力目标表现出更高水平的权力感知。     

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。     

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。     

冲突情境下幼儿的选择性信任和信念修正

幼儿如何选择性地采信他人提供的信息、获取知识, 是幼儿社会认知发展研究的重要问题。除客观的信息内容外, 信息传递者的特征也影响幼儿的选择性信任。另外, 在不确定情境下, 他人证言与幼儿已有信念可能存在冲突, 在二者冲突的情境下, 幼儿是否可以采信他人的证言, 并最终改变幼儿的已有判断是以往研究忽略的问题。本研究考察了当母亲证言与幼儿已有信念冲突时, 不同程度的冲突情境(面对不同比例的合成动物时)对幼儿选择性信任和信念修正的影响。研究采用冲突信息源范式, 向74名4~6岁幼儿呈现对不同比例合成动物(50%-50%任务 vs 75%-25%任务)命名的证言, 考察幼儿对信息提供者的询问意愿、对证言的信任情况和在证言前后对合成动物的判断(信念修正)。信息提供的一方为母亲(提供相似度低的动物名称), 另一方为陌生人(提供相似度高的动物名称)。结果发现, 幼儿的选择性信任和信念修正受到母亲证言与已有信念冲突程度的影响。在低冲突情境下, 幼儿对母亲证言的询问意愿和外显信任均高于高冲突情境。幼儿的信念修正存在年龄差异, 在低冲突情境下, 年长幼儿比年幼幼儿更倾向于改变已有信念, 在高冲突情境下, 年长的幼儿比年幼幼儿更不愿意改变已有信念。本研究结果表明, 当母亲的证言与幼儿已有信念冲突时, 中国幼儿可以区分不同程度的冲突情境, 并且可以根据冲突的程度进行选择性信任和信念修正。     

不确定性容忍度对模糊决策中决策偏好的影响及其情景依赖性*

研究以Ellsberg选瓶任务为决策材料,探讨了不同任务特征下个体不确定性容忍度对模糊决策中决策偏好的影响。结果发现,获益情景下:高概率时高、低容忍度个体对模糊选项的选择无显著差异,均偏好模糊规避;中概率时低容忍度个体比高容忍度个体表现出更低程度的模糊规避,前者倾向于模糊中立,后者倾向于模糊规避;低概率时两者对模糊选项的选择无显著差异,均倾向于模糊中立。损失情景下:高概率时两者对模糊选项的选择无显著差异,均倾向于模糊寻求;中概率时低容忍度比高容忍度个体更偏好模糊寻求,前者倾向于模糊寻求,后者倾向于模糊中立;低概率时两者对模糊选项的选择无显著差异,均倾向于模糊规避。这表明,不确定性容忍度对模糊决策偏好产生作用,但这种作用会受到损益概率和损益结果的影响,具有情景依赖性。     

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。     

信任还是设防？互动博弈中社会善念对合作行为的促进效应

社会善念是个体在人际互动中充满善意地关注、尊重并保护他人选择的需要和权利的行为,通过实施社会善念有助于提升他人的合作行为。为检验这一假设,本实验设置了“施—受”双方的互动博弈情境,采用“物品选择游戏”操纵实施者的社会善念水平,分别利用信任博弈和公共物品游戏测查接受者在互动过程中的信任水平和合作行为。结果发现：相比于低社会善念组,被试在高社会善念组中表现出更高的信任水平和合作行为。进一步路径分析也发现,信任在感知社会善念与合作行为间发挥着部分中介作用。由此可见,社会善念行为的实施为互动双方建立信任关系提供了重要线索,降低了人们时时“设防”的监控动机,使合作带来的利益双赢成为可能。     

伙伴选择对合作行为的影响作用与机制

伙伴选择是指个体根据其他个体能否给自己带来获益而选择或拒绝与他们建立伙伴关系的行为。伙伴选择对合作行为具有非常重要的影响, 表现为：个体只要有离开或自主选择伙伴的机会即可促进合作; 若能了解到伙伴的行为或特质层面的信息, 则可以进一步促进合作。基于目前研究, 伙伴选择主要可能通过4种具体机制促进合作行为, 即离开或拒斥的惩罚机制, 寻求合作者的奖赏机制, 分类匹配机制以及生物市场中的竞争机制。未来还需要从厘清伙伴选择的概念, 提升研究的生态效度, 深入探索其促进合作的内在机制, 尝试用伙伴选择解决伙伴控制条件下的合作问题, 以及探索中国文化背景下的伙伴选择与合作等方面开展进一步研究。     

Characteristics of affected third parties and cooperative behavior in social dilemmas

ABSTRACT

The studies described in this article explore the influence of an under-emphasized determinant of cooperative behavior in social dilemmas: affected third parties. Two experiments examined the effect of characteristics of third parties on individual cooperative behavior in social dilemmas, and identified mechanisms associated with these relationships. Study 1 demonstrated that third-party need affects individual cooperative behavior, and tested prosocial motivation and intra-group trust as mediators of this relationship. Study 2 provided further elaboration by demonstrating that individual cooperative behavior was reduced when a needy third party was low on reliability, and by showing that prosocial motivation and intra-group trust mediated this relationship. This research connects the literatures on individual cooperation in social dilemmas and relational job design, and demonstrates why third parties influence individuals’ cooperative behavior.     

Confiance rapide et gestion des ressources temporelles dans les équipes dynamiques militaires : une approche expérimentale

In combined operations, military aviators are increasingly working in “swift starting action teams”, which increases the uncertainty about the behavior of the ephemeral partner for the mission to be carried out together. To reduce it, ephemeral interpersonal trust (or swift trust) should help optimize the management of time resources by moderating the time spent checking the partner's work and preserving performance. This study proposes a device for inducing three different levels of swift trust to experimentally evaluate the management of time resources, checking and individual performance in ephemeral STAT-type teams. The results indicate that a low level of swift trust results in increased time resources allocated to complete the entire activity while maintaining the level of performance.     

Motivated information processing, strategic choice, and the quality of negotiated agreement

The authors tested a motivated information-processing model of negotiation: To reach high joint outcomes, negotiators need a deep understanding of the task, which requires them to exchange information and to process new information systematically. All this depends on social motivation, epistemic motivation (EM), and their interaction. Indeed, when EM (manipulated by holding negotiators process accountability or not) was high rather than low and prosocial rather than proself, negotiators recall more cooperative than competitive tactics (Experiment 1), had more trust, and reached higher joint outcomes (Experiment 2). Experiment 3 showed that under high EM, negotiators who received cooperative, rather than competitive, tactics reached higher joint outcomes because they engaged in more problem solving. Under low EM, negotiators made more concessions and reached low joint outcomes. Implications for negotiation theory and for future work in this area are discussed.     

Psychological distance boosts value-behavior correspondence in ultimatum bargaining and integrative negotiation

The present research examined how construal level and social motivation interact in influencing individuals’ behavior in social decision making settings. Consistent with recent work on psychological distance and value-behavior correspondence (Eyal, Sagristano, Trope, Liberman, & Chaiken, 2009), it was predicted that under high construal level individuals’ behavior is based on the social motivation they endorsed, no matter whether pro-social or pro-self. Two experiments involving ultimatum game (Experiment 1) and face to face negotiation (Experiment 2) supported the “increased value-behavior correspondence” hypothesis by showing that pro-socials were more cooperative and pro-selves were more competitive under high rather than low construal level. Implications for research on social decision making and psychological distance are discussed.     

Risk as a Determinant of Trust

I propose that the degree of trust an individual forms toward an interaction partner is a function of the degree of risk that is involved in the situation. Two experiments were conducted in order to test this hypothesis. Subjects had to decide whether they would lend either an inexpensive scientific book (low-risk condition) or an expensive scientific book (high-risk condition) to a fictitious male fellow student. After subjects had made their decision, they had to indicate the degree of trust they had formed toward the interaction partner by means of a scale that referred to similar trust-related interactions. The hypothesis was clearly confirmed: The degree of trust was higher in the high-risk condition than in the low-risk condition. Results are explained in terms of self-perception theory. Implications are discussed.     

Understanding trust and confidence: two paradigms and their significance for health and social care

Trusting agents characteristically anticipate beneficial outcomes, under conditions of uncertainty, in their engagement with others. However, debates about trust incorporate different interpretations of risk, uncertainty, calculation, affect, morality and motivation in explaining when trust is appropriate and how it operates. This article argues that discussions about trust have produced a concept without coherent boundaries and with little operational value. Two paradigms are identified, which distinguish the characteristics of trust and confidence. It is argued that a reliance on confidence in human affairs makes trust redundant and that this has undesirable moral consequences. Discussion is illustrated by the UK Government's 'modernisation' policy in health and social care, which privileges confidence in systems over trust in moral agents.     

The prediction of group motor performance from individual member abilities

Two experiments were conducted to investigate the prediction of group performance on the motor-maze task from individual member abilities. In both experiments subjects performed 20 individual trials on the maze task in an initial session prior to the actual experiment. On the basis of these individual performance scores, two-person groups were formed so that the groups represented a range of average ability levels and a range of discrepancies in abilities between partners. In Experiment 1, all groups performed a cooperative and a noncooperative group task in separate sessions both involving competition with another group. Only the cooperative group task was used in Experiment 2, but all groups performed under both competitive and noncompetitive conditions. Multiple regression analyses yielded a moderate, positive relationship between member abilities and group performance in both experiments; group performance on the highly cooperative task was dominated by the lower-ability partner.     

Deciding to defect: the effects of video-game violence on cooperative behavior

This experiment examined the effect of video-game violence on cooperative decision making. Participants (N= 48) were randomly assigned to play either a violent or a nonviolent version of the video game Doom in dyads. Following the video-game task, participants were separated and given an opportunity to choose to cooperate with their partner for mutual gain, withdraw from the interaction, or exploit their partner for their own benefit. Participants in the violent condition were significantly more likely to choose to exploit their partners than participants in the nonviolent condition. These findings suggest that playing violent video games may undermine prosocial motivation and promote exploitive behavior in social interactions.
