Cooperation in repeated interactions: A systematic review of Centipede game experiments, 1992–2016

Cooperation is a fundamental form of social interaction, and turn-taking reciprocity one of its most familiar manifestations. The Centipede game provides a formal model of such alternating reciprocal cooperation, but a backward induction (BI) argument appears to prove logically that instrumentally rational players would never cooperate in this way. A systematic review of experimental research reveals that human decision makers cooperate frequently in this game, except under certain extreme conditions. Several game, situational, and individual difference variables have been investigated for their influence on cooperation. The most influential are aspects of the payoff function (especially the social gain from cooperation and the risk associated with a cooperative move), the number of players, repetitions of the game, group vs. individual decisions, and players’ social value orientations (SVOs). Our review of experimental evidence suggests that other-regarding preferences, including prosocial behavioural dispositions and collective rationality, provide the most powerful explanation for cooperation.     

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。     

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。     

抑郁对社会决策的影响

从社会决策角度出发,依托博弈论的经典范式是研究抑郁症病人人际与社会功能障碍的一个切入点。Ruff和Fehr （2014）提出在社会决策中存在三类情境,即社会反馈、替代性评价、社会原则。我们从这个理论框架出发,发现抑郁症病人在社会反馈加工中存在社会性快感缺失,对社会拒绝的敏感性增强;在替代性评价过程中,共情和心理理论能力减弱;抑郁症病人对决策中的社会原则（公平、合作）存在适应不良现象,如过度利他性。未来的研究一方面可进一步探索抑郁症病人的社会性快感缺失现象,另一方面可采用经颅电/磁刺激与脑成像技术结合或超扫描技术,提高研究结果的解释力和生态效度。     

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。     

4、5岁儿童一般语言能力和心理理论关系的纵向研究

为探明汉语儿童语言和心理理论的发展, 追踪二者的动态关系及相互作用的方向, 本研究以80名4、5岁儿童为研究对象, 纵向探查了前后相隔6个月的儿童的一般语言能力和心理理论的发展状况, 并运用交叉-滞后组相关分析初步探查了二者是否存在因果关系及可能的作用方向。结果表明：4~5岁是汉语儿童心理理论发展的重要时期, 语言在这一阶段也得到快速发展。交叉-滞后组相关分析发现了4岁儿童语言和心理理论因果关系的证据, 但随着年龄的增长, 语言对心理理论的前提基础作用有所减弱, 5岁儿童没有表现出这种因果关系。     

Age-Related Changes in Children's and Adults’ Explanations of Interpersonal Actions

We investigated the content of children's and adults’ explanations of interpersonal actions. Participants were 5-, 7-, and 9-year-old children, as well as adults, who were presented with 8 stories containing either prosocial or antisocial target actions, and asked to explain why each actor performed that action. In half of the stories, an interpersonal event preceded the action. Children and adults provided situational and mental-state explanations, but mental-state explanations were especially common for antisocial actions not preceded by an interpersonal event. With increasing age, participants explained prosocial actions by referring to the actor's goals, but referred to the actor's emotions and beliefs to explain antisocial actions. Finally, adults were most likely to mention psychological goals. These results suggest that (a) elementary school children provide a variety of explanations for interpersonal events; (b) children use different types of explanations flexibly, depending on the context and nature of the target action; (c) the frequency of different types of explanations for interpersonal actions changes during childhood; and (d) between middle childhood and adulthood, the recognition of psychological goals increases greatly.     

The Intelligence of White Foreign Born Criminals

Children's understanding of cognition increases greatly between early childhood and adolescence. This increase provides a developmental bridge between young children's understanding of mental states to adolescents' and adults' epistemological reflection. The author presents a framework for describing developmental changes in children's understanding of cognitive activities. He distinguishes 4 aspects of children's understanding of cognition: (a) knowledge of mental states, (b) knowledge of occurrence of particular activities, (c) knowledge of organization of cognitive activities, and (d) epistemological thought. He discusses phenomenological awareness of cognitive activities and social experience as influences on children's concepts of cognition.     

心理理论研究的毕生取向

心理理论经典研究范式主要关注的是3～5岁年龄的儿童。随着研究的不断深入,学者们开始逐渐把眼光投向人的生命全程,表现在：开始考察4岁以前儿童有关心理理论的问题;尝试对自5岁直到老年期的心理理论发展情况进行探讨;提出了心理理论的毕生发展观。心理理论研究的毕生(life-span)取向已初露端倪,该取向将是今后心理理论领域研究的重要发展方向之一。     

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。
