社会阶层与亲社会行为：回报预期的调节作用

近年来关于社会阶层和亲社会行为关系的研究不少,但结论不一致。基于此,本研究假设亲社会行为的社会阶层差异可能与对回报水平的预期有关。实验改编自“独裁者”游戏,通过网络模拟情境进行,采用2（社会阶层：高、低）×2（回报预期：高、低）的混合设计（其中社会阶层为被试间变量）,考察了不同社会阶层被试在两种不同回报预期条件下,亲社会行为的差异。实验结果表明：回报预期和社会阶层之间存在交互作用,进一步的简单效应分析表明,当预期目标有较高的回报水平时,高低社会阶层的亲社会行为差异不显著。当预期目标有较低的回报水平时,与高社会阶层相比,低社会阶层的亲社会行为明显减少。说明回报预期对不同社会阶层的亲社会行为起显著的调节作用。     

共情对亲社会行为的影响及神经基础

亲社会行为是指那些使他人获益的行为,这类行为具有重要的进化意义和现实意义。作为影响亲社会行为的重要因素,共情在认知神经科学领域得到了广泛研究。脑岛等脑区的激活与消极情绪体验有关,是情绪共情的神经基础,利于产生亲社会行为动机;颞顶联合区等脑区参与对他人意图的理解,是认知共情的神经基础,利于个体选择有效方式帮助别人。女性在共情时激活额下回等与情绪有关的脑区,而男性在共情时激活颞顶联合区等与认知有关的脑区,这为男女个体在亲社会行为表现上的差异提供了新证据。未来研究应完善与亲社会行为有关的脑区功能的解释,综合多种影响因素,结合病理学研究考察共情对亲社会行为的影响及神经基础。     

大学生在社会困境中的公平决策:社会价值取向的影响

通过两项研究考查大学生在社会困境中的行为决策及公平感体验,检验社会价值取向的影响作用,有效被试分别为85名和84名。结果表明:(1)亲社会者比亲自我者更倾向做公平决策;信息对称比不对称条件更促进被试做公平决策;女生比男生更倾向做公平决策。(2)性别在社会价值取向与信息对称性对公平决策的影响中起调节作用,社会价值取向显著影响男生的公平决策,信息对称性显著影响女生的公平决策。(3)社会价值取向显著影响个体对不公平的容忍度,亲社会者更不容忍不公平行为。(4)对于利己的不公平行为,被试都倾向接受,亲社会者并不比亲自我者体验到更强的内疚情绪;对于不利己的不公平行为,被试都倾向拒绝,且产生较强的不公平感及气愤情绪。     

大学生亲社会行为决策中自尊与情绪信息的交互作用

采用自编亲社会行为决策材料,以行为决策对象的被选频次为指标,通过对65名男女大学生的研究,结果发现：1）在阈上和阈下的＂图-词＂启动范式下,均存在显著的情绪启动效应,且实验性情绪变化明显。2）在正性图片启动下,自尊水平和情绪效价对亲社会行为决策均无显著影响,但二者的交互作用显著,低自尊个体在负性情绪下的亲社会行为决策存在显著性差异;行为决策对象对大学生亲社会行为决策有显著影响,与自尊水平、情绪效价之间的交互效应不显著;在负性图片启动下,自尊水平、情绪效价、行为决策对象以及三者的交互作用对亲社会行为决策均无显著影响。3）总体上,大学生亲社会行为决策受自尊水平与情绪效价的交互作用影响,也受行为决策对象及其与自尊水平、情绪效价的三次交互作用的影响。     

敬畏对亲环境行为意向的影响

采用回忆书写、视频和阅读书写范式启动敬畏,考察了敬畏与亲环境行为意向的关系。结果显示,相较于中性控制组,敬畏情绪回忆书写组（实验1）、视频启动组（实验2）和阅读书写组（实验3）的亲环境行为意向更高。结果表明,敬畏有助于促进个体的亲环境行为意向。     

幼儿情绪理解、亲社会行为与同伴接纳之间的关系

以131名3~6岁的儿童为被试,探讨了不同层次情绪理解能力的发展及其与儿童的亲社会行为、同伴接纳之间的关系。结果表明,儿童的表情识别、情绪解码和二级情绪理解能力表现出了不同的发展趋势;在总体上,儿童的情绪解码能力和亲社会行为能显著地预测其同伴接纳;情绪理解和亲社会行为对儿童同伴接纳的影响存在一定的年龄效应,情绪解码能力是年幼儿童同伴接纳的最佳预测变量,亲社会行为则是年长儿童同伴接纳的最佳预测变量。     

关系持续预期与规范目标激活：合适性逻辑下的信任决策

人际互动过程中,信任作为决策过程受到诸多因素的影响,信任的决策逻辑在不同的研究背景中存在冲突。本研究以合适性为信任决策框架,互动关系为激活规范目标的变量,分析了存在互动关系持续预期和不存在互动关系持续预期对信任行为的影响及其影响机制。结果表明：（1）被试间存在关系持续时,信任水平较高;关系持续预期消失时,信任水平显著下降。（2）被试对关系持续的重要性感知与其信任决策显著相关。（3）情境中的目标未被激活时,个体的信任倾向与信任决策显著相关;而当情境目标被激活时,信任倾向与信任决策相关不显著。     

价值取向与社会距离影响经济决策的合作与冲突行为：Chicken Game的证据

采用Chicken Game博弈任务,考察了不同社会价值取向个体（亲社会者与亲自我者）在面对不同社会距离的博弈对手（朋友和陌生人）时表现出的合作与冲突行为。研究结果发现：（1）社会价值取向与社会距离交互影响个体的合作与冲突行为;（2）社会价值取向影响选择策略的反应时,亲社会者选择合作的反应时长于选择冲突的反应时,亲自我者选择合作与选择冲突的反应时没有显著差异;（3）无论对亲社会者还是亲自我者,反馈类型都显著影响个体的合作与冲突行为的选择率以及随后决策的反应时。上述结果表明,个体的合作或冲突行为,并非单一地受到社会价值取向的影响,更可能是受到个人因素（社会价值取向）与其他社会因素（比如,社会距离）的共同调节,并且在这一过程中个体会根据决策后反馈信息不断的调整自己的行为策略。     

无意识目标对道德取向的调节作用

已有研究表明目标可以在无意识的条件下被激活并自动地引导行为以达成目标,但该过程是否通过调节心理准备状态实现尚不清楚。本研究考察了无意识目标对个体道德取向的影响。实验1通过语义启动方式激活被试的成就目标,结果发现,与未激活任何目标的被试相比,激活了无意识成就目标的被试更偏向功利主义道德取向。实验2激活被试母亲的概念,结果发现这部分被试比对照组更偏向道义主义道德取向。上述结果表明,自动激活的目标可以影响个体的道德取向,使个体面对道德情境时能做出更合适的行为以达成目标。     

高确定性情绪（开心、愤怒）与低确定性情绪（悲伤）对信任的影响

本研究通过信任游戏的实验范式探讨了在与“受信任者”高/低可信赖性有关的信任线索时,具体情绪的确定性维度对信任行为的影响。实验一发现,当被试被告知“受信任者”在可信赖量表上的得分（高/低）时,个体在高确定性情绪（开心和愤怒）下的信任判断比低确定性情绪（悲伤）下的信任判断上更容易被受信任者的“可信赖性”水平的高低所影响;实验二发现,当告知被试“受信任者”的群体身份（内/外群）时,个体在高确定性情绪（开心和愤怒）下的信任判断比低确定性情绪（悲伤）下的信任判断更容易被受信任者的“内外群”身份所影响。上述结果表明,高确定性的情绪比低确定性的情绪更容易使被试的信任判断受到与“受信任者”是否值得信赖有关的线索所影响。     

The Last Dictator Game? Dominance,Reactivity, and the Methodological Artefact in Experimental Economics

The Dictator Game (DG), one of the best-known designs in experimental social science, has been extensively criticized, and declared by some to be defunct, on the grounds that its results are the product of a research artefact. Critics of the DG argue that the behaviour observed in the game (where agents frequently decide to share their money with strangers) is not the outcome of genuine pro-social preferences but must, instead, be interpreted as a response to the cues given by the experimental design, where these cues signal that the game is about ‘sharing’ (i.e. about altruism or pro-social behaviour). Despite this criticism, the DG continues to be extensively used, and some have defended its validity as an instrument capable of measuring the role of social pressure and social norms against economic motivations. This article examines the assumptions implicit in the claim that the DG results are artefactual and spells out the conditions under which the game can be used to test hypotheses about pro-social behaviour. To conclude we show how the DG debate helps to illuminate the pitfalls embedded in the abandonment of the dominance principle, and argue that this is crucial to the expanding agenda of experimental economics.     

眼睛效应不稳定与感知规范：一个新视角

眼睛效应指人们面对眼睛或类似眼睛的图案时会发生行为改变的现象。但是, 眼睛效应的稳健性备受争议, 主要有4种观点：促使人们更亲社会、更遵守社会规范、降低反社会行为、无效果。结合规范错觉和创新扩散理论, 基于感知规范的视角, 当感知亲社会规范流行程度较高时, 眼睛效应既会“促进亲社会行为”或“促进人们遵守社会规范”, 也会“降低反社会行为”; 但当感知亲社会规范流行程度较低时, 眼睛效应对一些反社会行为“无效果”; 当规范错觉较大且无规范干预时, 眼睛效应同样对一些反社会行为无效果。因此, 将以上4种争议观点整合为“不同感知规范条件下的眼睛效应”, 揭示了眼睛效应不稳定的原因, 为未来实证研究和实践应用提供理论基础。     

Aggression Norms in the Classroom Social Network: Contexts of Aggressive Behavior and Social Preference in Middle Childhood

In a cross‐sectional sample of African‐American 2nd–4th grade students (N = 681), we examine the moderating effects of classroom overt and relational aggression norms on peers’ social acceptance of classmates who exhibit overt and relational aggression in urban schools. Extending theory and research on classroom norms, we integrate social network data to adjust aggression norms based on children’s direct and indirect connections in the classroom. Results of multilevel models indicate that network‐based classroom aggression norms moderated relations between children’s aggressive behavior and their social preference. Specifically, children benefited socially when their form of aggressive behavior fit with what was normative in the classroom social context. The moderating effect of classroom aggression norms was stronger for the association between overt aggression and social preference than relational aggression and social preference. Relationally aggressive youth were socially preferred by peers regardless of the classroom norm, although this positive association was magnified in classrooms with higher levels of relational aggression. Future research focused on aggression norms within classroom social networks are discussed and implications for school prevention efforts are considered.     

Anger, Blame, and Dimensions of Perceived Norm Violations: Culture, Gender, and Relationships

From a social cognitive perspective on anger, we attempted to examine the structure of perceived norm violations and their relationships with anger. We asked 884 university students from 4 countries (United States, Germany, Japan, and Hong Kong) to rate their experiences of being harmed in terms of norm violations, angry feelings, blame, and relationship with the harm doers. We found 2 culturally common dimensions in perceived norm violations (informal interpersonal norms and formal societal norms), and these dimensions substantially increased both angry feelings and blame in almost all cultural groups. The violation of interpersonal norms generally evoked anger more frequently than that of societal norms, but there were interactions between culture and relationship closeness and between gender and relationship closeness.     

Emotions as guardians of group norms: expressions of anger and disgust drive inferences about autonomy and purity violations

Other people’s emotional reactions to a third person’s behaviour are potentially informative about what is appropriate within a given situation. We investigated whether and how observers’ inferences of such injunctive norms are shaped by expressions of anger and disgust. Building on the moral emotions literature, we hypothesised that angry and disgusted expressions produce relative differences in the strength of autonomy-based versus purity-based norm inferences. We report three studies (plus three supplementary studies) using different types of stimuli (vignette-based, video clips) to investigate how emotional reactions shape norms about potential norm violations (eating snacks, drinking alcohol), and contexts (groups of friends, a university, a company). Consistent with our theoretical argument, the results indicate that observers use others’ emotional reactions not only to infer whether a particular behaviour is inappropriate, but also why it is inappropriate: because it primarily violates autonomy standards (as suggested relatively more strongly by expressions of anger) or purity standards (as suggested relatively more strongly by expressions of disgust). We conclude that the social functionality of emotions in groups extends to shaping norms based on moral standards.     

Social desirability, approval and public good contribution

Behaviour in public good experiments is usually attributed partly to rational self-interest and partly to social norms and preferences. This paper examines if sensitivity to social desirability affects public good contribution and in what way. A pre-experimental measure of social desirability (SDS17) was used to match partners in a two-person public good game. Half the participants received experimenter approval based upon their investment. Contrary to predictions, the highest public good investment was by low social desirability participants in the approval condition. Social desirability was not positively related to pro-social behaviour. We consider its relation to experimental and social conformity.     

Emotions as signals of normative conduct

Social interactions are heavily norm-based and these norms need to be learned. For this, the emotional reactions of other's in response to a norm transgression can serve as signals. We were able to show that when a group responds with anger to a norm transgressing behaviour, participants were better able to correctly infer the norm than when the group responded with sadness or emotional neutrality. We further tested a process-model showing that this inference is based on the participants' understanding of the groups' appraisals of the behaviour. That is, participants who were able to reverse engineer the underlying appraisal of norm-incompatibility from the emotion expressions inferred the norm more readily. Humans as a social species, require efficient means to quickly adapt to new situations and to perform flawlessly in social contexts. Emotion information is one of the instruments that can be used in this quest.     

Social norms and human cooperation

The existence of social norms is one of the big unsolved problems in social cognitive science. Although no other concept is invoked more frequently in the social sciences, we still know little about how social norms are formed, the forces determining their content, and the cognitive and emotional requirements that enable a species to establish and enforce social norms. In recent years, there has been substantial progress, however, on how cooperation norms are enforced. Here we review evidence showing that sanctions are decisive for norm enforcement, and that they are largely driven by non-selfish motives. Moreover, the explicit study of sanctioning behavior provides instruments for measuring social norms and has also led to deeper insights into the proximate and ultimate forces behind human cooperation.     

行为博弈与社会交换

行为博弈与社会交换看似两个毫无关联的现象和研究领域,却有着内在的、实质性的联系。行为博弈也是一种社会交换或以社会交换为机制,社会交换则表现为一种行为博弈或有着内在的博弈性质。行为博弈与社会交换互为表里、互为机制、水乳交融,行为博弈是社会交换的行为博弈,社会交换是行为博弈的社会交换。以行为博弈的眼光来看待社会交换或以社会交换的意识来研究行为博弈,跨领域的研究洞视,各自互为对方启动了一方别开生面的研究天地,为枯燥乏味的传统博弈研究和死水微澜的社会交换领域凭添了一丝新鲜气息。     

第三方惩罚的演化与认知机制

第三方惩罚一般是指当违反社会规范的行为与自身利益无关时,个体牺牲自我利益来惩罚违规者的行为。最近的研究发现,对于个体而言,第三方惩罚是一种具有适应性的信号,包括建立良好的声誉以及威慑违规者。不同情境下第三方惩罚的功能有所差异,它是一种特殊的利他行为。第三方惩罚依赖于多个系统,涉及情绪反应、共情等社会认知能力以及认知控制等中央执行能力。探讨该行为的演化和认知机制也能贡献于个体、群体和人际层面的社会心理服务工作。
