社会价值取向和反馈方式对公共物品困境中决策行为的影响

本研究通过模拟投资实验和问卷来探讨重复型公共物品困境中社会价值取向（SVO）与信息反馈方式对决策行为的影响。结果表明：(1)合作型SVO的个体比非合作型个体表现出更多的合作行为;(2)SVO与信息反馈方式的交互作用岁实验轮次越来越显著,非合作型的个体会受信息反馈方式的影响,而合作型个体则不易受反馈方式的影响;(3)与无反馈的条件相比,集体反馈倾向于促进个体的合作行为,个体反馈倾向于抑制合作行为,但反馈所造成的适应性改变使情况更为复杂。     

多决策方法多交流方式的群体决策比较

采用人员选拔的实验室模拟实验,以160名被试组成40个4人群体,对4种决策方法和2类交流方式的群体决策进行了比较。结果发现（1）决策方法和交流方式对于讨论过程的信息交流具有显著影响;（2）以计算机为中介进行决策的被试知觉到的任务难度要高于面对面决策条件;决策方法对于群体成员有关实验任务难度知觉具有主效应;交流方式和决策方法对于群体决策过程满意感和结果满意感没有显著影响;（3）在以投票轮次来表明群体达成一致意见所需时间上,决策方法对于投票轮次具有显著影响。恶魔式辩护、辨证式查询两种方法下所需的投票轮次多于专家意见法和自由讨论法的投票轮次。     

社会两难行为理性特点的实验分析

本研究运用定量和定性的方法探讨了动态适应性学习条件下两难行为的理性特点及其影响因素。72名杭州本科生参加了本实验,结果发现:1、在有限次重复的两难博弈实验中,人们的两难行为不符合纳什博弈理论,进一步的定性分析指出,这种两难行为体现出“社会理性”的特征;2、在高奖罚的条件下,人们更容易做出接近“纳什均衡点”决策;3、群体规模和反馈方式对人们的对策行为影响不显著,但是,进一步的定性分析部分支持了群体规模的社会理性解释。     

方言对社会决策及情绪的影响——-来自电生理的证据

方言是心理学本土化研究的新方向,本研究旨在考察语言类型（方言、普通话）对群体和个体社会决策的影响。实验1通过改编的公共物品博弈范式,发现方言条件下信任与合作水平、主观评定积极情绪和心率的变化值更大,皮肤电无显著变化;普通话条件下信任在主观消极情绪评定和合作行为间发挥着完全中介作用。实验2利用改编的最后通牒博弈范式,发现不公平的￥2-￥8分配方案下方言条件的接受率显著高于普通话条件,提议越公平接受率越高。结果表明方言会影响人们认知、情绪和决策行为,研究为语言和决策领域的探索提供了新思路。     

群体任务中合作行为的跨阶段演变

合作是电子商务时代群体工作的重要基础。本实验通过资源两难任务研究群体工作中的合作行为的演变。111名被试参加了实验。研究发现,在动态博弈过程中,群体其他成员行为的多个阶段反馈将成为决策者合作机制形成的主要基础,与决策者价值等内部因素和环境不确定性等外部因素,共同影响合作行为的演变     

长期合作学习小组中的集体智慧及其影响因素研究

合作学习是应对信息时代学习困境的有效途径。研究一探索了合作学习群体中是否存在集体智慧,研究二比较了互动小组和名义小组在创新观点产生任务中的表现,研究三考察了合作学习小组在群体决策中的表现及其成员的观点和主观自信的影响。研究表明：在长期合作学习小组的多重任务表现中存在代表群体整体一般能力的C因素,即存在集体智慧;在创新观点的产生中,社会影响不利于集体智慧发挥作用;在困难问题解决的判断与决策中,集体智慧发挥的作用更明显,较不会受到个别成员的主观自信、实力和多数人意见左右。建议在合作学习等群体活动中通过策略选择和规则设置促进集体智慧发挥作用。     

两难对策中价值取向对群体合作行为的影响

采用实验室方法,通过两难对策任务的情景模拟,研究群体成员的价值取向对群体合作行为的影响。62名被试参加了实验。结果发现：（1）群体合作行为受到群体成员价值取向的影响,合作型成员会产生更多的群体合作行为;（2）群体的合作行为也受到合作者对策策略的影响,对应策略将导致最多的群体合作行为;（3）两者的交互作用对群体的合作行为具有影响,但不显著。     

反馈干预对学习判断的影响

将反馈干预作为外部线索引入元记忆研究,采用重复学习任务,在第一轮次学习-测验之后插入反馈干预,用两个实验分别考查任务反馈和能力反馈两种形式下的反馈效价对第二轮次即时学习判断的影响.结果表明：①在学习过程中,学习者会进行自我监测;②在任务反馈形式下,反馈信息与自我监测信息冲突,导致反馈干预对元认知监测和认知过程没有影响;③在能力反馈形式下,反馈信息与自我监测信息的冲突消失,结果消极反馈影响了元认知监测.由此得出结论：只有在不与自我监测信息冲突的情况下,反馈干预才对学习判断产生影响.此外,在有反馈干预的情况下,两个实验中都出现了显著的练习伴随低估效应.     

儿童合作策略水平发展的实验研究

本实验将合作策略分为四个水平,随机选取幼儿园中班、大班及小学一、二、三年级的被试300名,在鼓励合作的条件下,通过游戏的方式,研究儿童合作行为发展的趋势.实验结果表明随着儿童年龄的增长,合作行为越来越多,且合作水平越来越高,而竞争行为逐渐减少;性别因素对合作行为影响不大,但对竞争行为却有显著的影响.这可能与我国的家庭教育、学校教育有一定的关系.     

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。     

Maintaining social identity in a mixed-gender setting: Minority/majority status and cooperative/competitive feedback

This study tested the applicability of Tajfel and Turner's (1986) Social Identity Theory (SIT) to cooperative behavior in a mixed-gender setting. SIT suggests that as a “socially subordinate” group in a male-dominated society, women, when their gender is in the numerical minority, will engage in social competition in an attempt to enhance social identity. However, gender-based socialization may encourage men toward competition and women toward cooperation, regardless of group gender composition. In this study, male and female subjects were assigned to a six-person mixed-gender group in which their gender was either in the numerical minority or majority, and performed an interactive task under either cooperative or competitive feedback. An interaction of sex and feedback showed males in the cooperative feedback condition responded more competitively than did males in the competitive feedback condition, while females were equally cooperative in both feedback conditions. Feedback also interacted with the numerical ingroup/outgroup gender balance. While competitive feedback elicited little variation in subjects' responses across the ingroup/outgroup balance variable, the cooperative condition elicited greater competition from subjects in the numerical minority and greater cooperation from those in the numerical majority. Results were interpreted as partial support for SIT, while stressing the need for further investigation into gender as a unique influence on intergroup behavior.     

Social group salience and interethnic cooperation

This research was designed to test the adequacy of H. Tajfel's (1978, Differentiation between social groups: Studies in the social psychology of intergroup relations, New York/London: Academic Press) theory of social identity for predicting cooperative behavior among members of ethnically mixed groups. Equally divided by sex, subjects were 24 Anglo-American and 24 Hispanic undergraduate students attending the University of California, Riverside. Subjects were exposed to cooperative and competitive feedback in four-member, same-sex groups which varied in the ratio of Anglo to Hispanic subjects to create two conditions—a 3 to 1 versus a 1 to 3 in-group to out-group composition. Results showed that members of both ethnic groups were equally cooperative when their own group was in the numerical majority (low-salience condition). In the high-salience condition, however, when their own group was in the numerical minority, Hispanic subjects were significantly more competitive than Anglo subjects. In addition, while Hispanics were significantly more competitive in the minority than in the majority condition, Anglos showed a slight tendency to be less competitive in the minority than in the majority condition. These results are discussed in light of social identity theory and its application to the study of interethnic cooperation/competition in heterogeneous groups.     

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。     

Reducing the performance-cue bias in work behavior ratings: can groups help?

The authors examined whether the performance-cue bias can be reduced by relying on groups as raters. Study participants (N = 333) were provided with feedback regarding the performance of a workgroup and, after observing the group, assigned to an individual or group rater condition to complete a behavioral rating instrument. Results revealed that when provided with positive (vs. negative) feedback, individuals attributed more effective and fewer ineffective behaviors to the workgroup; however, group ratings were unaffected by the feedback. In addition, feedback biased the decision criteria and false alarm rates of individuals but not of groups. Discussion of when groups may attenuate versus amplify bias in performance appraisal judgments emphasizes 2 key elements-bias magnitude and task perception.     

同伴特点如何影响人们的合作与冲突行为?

人类的生存繁衍依赖于人们之间的相互合作,合作与冲突行为的研究近年来成为心理学的研究热点。本研究通过实验程序操纵Chicken Game中博弈同伴的特点,考察个体在社会困境中面对不同特点同伴时的合作行为。结果发现：(1)同伴道义论组和功利论组总和解率没有显著差异,同伴竞争组和合作组的总和解率也没有显著差异。(2)在与道义论以及合作型的同伴互动时,个体的行为没有明显受到上次博弈反馈的影响。(3)当同伴为功利论时,相比于上次博弈个体选择和解而同伴选择进攻,双方都选择和解时个体在当前博弈中更倾向于和解;(4)在同伴竞争组中,相比于上次博弈个体选择进攻而同伴选择和解,双方都选择和解时被试在当前博弈中会更倾向于和解。实验结果表明个体在博弈任务中会受到同伴特点的影响,并且同伴在博弈中的行为特点的影响更为显著。本研究从同伴特点来考察个体的合作行为,揭示了影响个体博弈行为的一种因素。     

社会困境中同伴行为、合作信念对合作变化的影响

本研究采用连续式公共物品困境,考察不同类型的个体在同伴遵守和违反均等规范两种条件下合作的前后变化及其可能的机制。结果发现：（1）依据行为决策对被试进行的分类与其社会价值取向之间不存在相关;（2）一人违反均等条件下被试的合作水平高于多人违反均等条件下的合作水平;（3）高贡献者在前后两次互动中维持较高的合作水平和信念水平;（4）低贡献者第二次决策时比第一次决策时更合作,这可能是由于他们的合作信念提高。     

Self-control and cooperation: different concepts, similar decisions? A question of the right perspective

Conflicts between an individual's long-term and short-term goals (i.e., self-control conflicts) and conflicts between individual and collective interests (mixed-motive situations) share some interesting features. In this article both types of conflicts are approached from a perspective hypothesis. The hypothesis holds that a decision maker's perspective on his or her decision determines whether either the long-term goals (the collective interests) or the short-term goals (the individual interests) will guide behavior. The hypothesis also implies that factors known to enhance cooperative choices in mixed-motive situations should also facilitate self-control. Three such factors are evaluated: group identification, self-efficacy, and mutual trust. We conclude that the perspective in which choice is considered part of an identifiable series of behaviors is most likely to result in cooperation or self-control.     

Group vs individual information processing: The effects of outcome feedback on decision making

Recent theories of individual decision making have emphasized the role of environmental feedback on decision performance and confidence. However, in relation to group decision making, feedback has received only minor attention. This study compared individual and group decision performance and confidence on a multicue personnel decision task under three different feedback conditions. Individuals and five-person groups decided whether to promote 48 different job candidates, and rated how confident they were in each of their decisions. Feedback as to the correctness of their decisions was provided after (a) every decision (Total Feedback), (b) only those decisions to promote the candidate (Partial Feedback), or (c) after none of the decisions (No Feedback). Results indicated that groups performed best under total feedback, while individuals performed best under partial feedback. In addition, greater amounts of feedback reduced individuals' confidence but had little effect on group member confidence. Implications for both current theory in decision making and group vs individual information processing are discussed.     

群体共情对群际关系的影响：基于社会冲突解决的视角

摘要：群体共情是指群体成员内化和间接体验另一群体成员的认知和情绪情感的过程。群体共情与个体共情不同,表现在身份感、共情偏好和文化影响的差异等方面。群体共情对群际关系具有促进作用,有助于减少群际冲突,促进群际亲社会行为。共情动机和文化框架转换是分析群体共情对群际关系促进机制的两个视角。未来研究可以探索群体共情与个体共情神经机制的差异,建立群体共情对群际关系影响的综合模型,探索群体共情在群际关系改善中的作用机制。
