权力感和群体身份对合作行为的影响——社会距离的中介作用

合作是人类持续发展的重要议题,本文通过实验探究了在合作的过程中,权力感所产生的影响及社会距离所产生的中介作用及群体身份所产生的缓解调节作用。实验包括利用角色扮演法、情景回忆法来操控个体权力感,虚拟与真实的公共物品范式、囚徒困境范式来测量人际合作,通过IOS问卷测量社会距离,并用最简群体实验范式来控制群体身份。本文三个实验的证据表明:(1)在虚拟的投资游戏中,高权力感个体的合作行为显著少于低权力感的个体;(2)在互动情境中,个体所感知到的与其互动对象的社会距离,在权力、合作之间起到部分中介的效应;(3)对于同组组内成员,高权力感个体相较于低权力感个体,有更多的合作行为。     

群体身份变换性对老年人印象更新的影响：共同内群体认同的中介作用

群体印象更新对于促进群际和谐具有重要的现实意义。本研究采用最简群体再分类范式, 通过4个实验考察了群体身份变换性对老年人外显与内隐印象更新的影响以及共同内群体认同的中介作用。结果发现, 群体身份变换性不仅改变了对最简外群体的印象评价, 而且也提升了年轻人对自然外群体老年人的外显印象评价, 但内隐印象评价的改变不明显; 共同内群体认同在群体身份变换性影响老年人的外显印象更新中起完全中介作用。这些发现不仅从群体身份变换性的视角进一步丰富和拓展了印象更新领域, 而且为群际互动中的偏见消除提供了最简群体再分类新方法。     

权力感和群体身份对合作行为影响——社会距离的中介作用

本文基于权力的社会距离理论作为切入点,探究在合作的过程中权力感所产生的影响及社会距离所产生的中介作用、群体身份所产生的缓解作用。利用角色扮演法、情景回忆法来操控个体权力感,采用虚拟与真实的公共物品范式、囚徒困境范式来测量人际合作,通过IOS问卷测量社会距离,并用最简身份范式来控制群体身份,从而让实验得以更好探究权力感对合作有如何的影响机制。本文通过三个实验,得出的实证证据表明：（1）在虚拟的投资游戏中,高权力感的个体捐赠金额是显著少于低权力感的个体;（2）在互动情境中,个体所感知到的与其互动对象的社会距离,在权力、合作之间起到部分中介的效应;（3）对于同组内的成员,高权力感的个体相比较于低权力感的个体,有着更多的合作行为。因此,权力感增加了个体的社会距离感知、从而减少了合作行为,但互动对象中的群体身份也在有效调节着这一心理现象。     

共同内群体认同对心理融合的促进效应及其机制

摘要：采用实验法从外显和内隐两个层面探讨共同内群体认同对心理融合的促进效应及其机制。实验1采用最简群体范式，通过重新范畴化操纵共同内群体认同，测量外显心理融合，结果发现，共同内群体认同显著促进了心理融合；实验2以民族群体为被试，采用GANT范式，从外显和内隐两个水平进一步探究共同内群体认同对民族心理融合的促进效应，结果发现，共同内群体认同促进了外显和内隐心理融合，感知相似性在共同内群体认同和心理融合间起中介作用。两个实验证明了共同内群体认同可以在外显和内隐两个水平促进心理融合，其促进作用是通过感知相似性实现的，也证实了GNAT范式在心理融合研究中的有效性。     

人际互动中的“自我-他人”区分:多水平的探索

人际互动的根本问题在于我们如何在表征自身想法和感受的同时试图去理解他人的心理和情感状态, 以驾驭复杂的社交环境。最近研究发现个体主要通过模拟自我加工过程实现对他人的理解, 但这种自我加工以及心理模拟在一定程度上混淆了自我与他人。因此, 为进行成功的人际互动, 大脑必须灵活区分自我和他人相关的表征, 这种能力被称为“自我-他人”区分(self-other distinction, SOD)。通过探讨感知、动作、认知以及情感等不同加工水平社会认知过程中的“自我-他人”区分及相应的研究范式, 实现对人际互动过程更全面而深入的理解, 为改善社会认知、情感障碍以及自闭症的干预提供依据。在此基础上, 提出了具体的研究展望。     

原始道德的自制力从何而来?

原始道德的自制力,主要表现为原始人对其生物本能的克制和调整。它来源于原始先民的精神心理与其群体社会生活的互动机制。具体包括两种生产活动的社会制约,神灵信仰的敬畏心理,自我观念的发生与发展,原始理解的能力与机制等因素。     

心理理论的遗传基础初探

心理理论在社会交往中起着关键作用,其认知过程包括对自我和他人的心理状态进行推断及预测下一步行为.心理理论在不同个体间具有差异,这种差异可能部分归因于与心理理论相关的神经化学物质如多巴胺、五羟色胺、催产素、血管加压素等.来自不同群体的研究结果还发现,与这些神经化学物质有关的基因多态性,如儿茶酚胺氧位甲基转移酶、多巴胺D4受体基因、5-羟色胺受体基因、催产素受体基因等都与心理理论的表现有关.     

心理理论与社会互动方式对初中生社会善念发展的影响

为了探讨初中生社会善念的发展特点及相关影响因素,实验1采用卡通插图范式和SoMi范式,以628名7~9年级初中生为被试,考察不同心理理论类型初中生的社会善念的发展;实验2使用社会互动情境和SoMi范式,以360名7~9年级初中生为被试,考察社会互动方式与反馈类型对不同年级初中生社会善念的影响。结果发现:(1)初中生的社会善念不存在年级和性别差异,但7年级中高情感心理理论初中生的社会善念显著多于高认知心理理论初中生;(2)7年级初中生在积极反馈条件下的社会善念较多,而8年级初中生在消极反馈条件下较多,9年级初中生在这两种条件下则不存在显著差异;(3)在合作情境中,初中生在积极反馈下的社会善念更多,而在竞争情境中,初中生在消极反馈下的社会善念更多。研究说明初中生的社会善念具有跨年龄和跨性别的稳定性,并且会受到心理理论、社会互动方式及反馈类型的影响。

The minimal group paradigm: Categorization into two versus three groups

The minimal group paradigm (Tajfel, Billig, Bundy and Flament, 1971) has been influential in the study of intergroup relations. Thus far, most minimal group experiments have divided the subjects either into two groups, or have categorized them on two separate dichotomous dimensions in cross-categorization experiments. This study examines the minimal group paradigm using three distinct and independent groups. Comparison of the results with three minimal groups with those of a baseline two-group experiment shows that with a three-group structure there is no significant ingroup bias. It is suggested that the two-group minimal group experiment shows ingroup bias because subjects access a dichotomous categorization, and that this dichotomous categorization primes a competitive orientation. A two-group context may be particularly efective in evoking an ‘us versus them’ contrast. Self-categorization as a group member is more likely to occur in the presence of two groups whereas three minimal groups renders an ‘us–them’ contrastive orientation less salient. The absence of intergroup discrimination found in the present minimal group study may be limited to the behaviour of minimal or artificially created groups. In the real world of intergroup relations discrimination towards multiple outgroups is a well-known phenomenon. While this study should be regarded as only preliminary research, further elaboration and specification of the conditions under which multiple group contexts may hinder intergroup discrimination is required.     

Crossed categorization versus simple categorization and intergroup evaluations: a meta‐analysis

Crossed categorization typically refers to the crossing of two dichotomous social dimensions, resulting in four groups (double‐ingroup, two mixed groups, and double‐outgroup). This paper reports the results of a meta‐analysis comparing the effects of crossed categorization on intergroup evaluations with the effects of simple categorization on intergroup evaluations. The crossed categorization paradigm is shown to increase or decrease ingroup bias, depending on how ingroup bias is defined in the crossed categorization paradigm. Moreover, just as in simple categorization, ingroup bias in crossed categorization is shown to be greater when the proportionate size of the ingroup is smaller. However, contrary to the patterns established in simple categorization, the reality of the group categorizations does not increase ingroup bias in crossed categorization. We discuss the implications of these results for future research on intergroup evaluations. Copyright © 2001 John Wiley & Sons, Ltd.     

Status differenttals and intergroup behaviour

This study investigated the independent effects of status differential on intergroup behaviour. Using a variant of the minimal group paradigm (Tueland Turner, 1979), subjects were categorized into groups of differing status (high, equal, low) with two levels of category salience (high, low). Using Tajfel's matrices subjects rated the creativity of products ostensibly produced by ingroup and outgroup members. Own group identification, intergroup perceptions and self-reported strategies on the matrices constituted the other dependent measures. Results indicated a main effect for group status but none for salience. Equal status groups discriminated against each other thus replicating the minimal intergroup discrimination effect. High and equal status group members were more discriminatory against outgroups and more positive about their own group membership than were low status group members. In contrast, low status group members engaged in significant amounts of outgroup favouritism. Results also showed that social categorization per se was sufficient to elicit more ingroup than outgroup liking amongst all group members regardless of status differentials between groups. Overall, the results illustrate important aspects of the interplay between group status, social identity, prejudice and discrimination.     

想象积极群际接触与群际关系改善实验研究述评

想象群际接触的基本思想指,在心理上想象一个积极的群际接触会创设一个心理接触的脚本,激发与外群体成员成功互动的观念,积极互动观念也就伴随产生对外群体的积极情感,导致对外群体的积极感知,增强和外群体进一步接触的意愿。想象群际接触的实验操纵比较简单,设置实验组和控制组,采用指导语的方式,但是想象群际接触的效应受群体地位、内群体认同状况等变量的调节。在未来的研究中, 需要注意提高研究的效度,加强机制、直接行为效应的研究,想象群际接触理论为改善群际关系提供了一个崭新的框架。     

On the immediate consequences of intergroup categorization: activation of approach and avoidance motor behavior toward ingroup and outgroup members

The present research argues that intergroup categorization has immediate behavioral consequences. Specifically, intergroup categorization is hypothesized to prepare the organism to respond differently to ingroup and outgroup members so that approach-like motor movements should be faster toward ingroup- versus outgroup-related stimuli. In contrast, avoidance-like behavior should be facilitated when reacting to outgroup versus ingroup members. Studies 1 and 2 test the basic hypothesis in relation to ethnic, national, age, and political categorization. Study 3 uses a minimal group paradigm to test the hypothesis in relation to newly formed groups. Across these experiments, participants were generally faster in performing approach-like motor movements toward ingroup members or avoidance behaviors toward outgroup members. The evolutionary function and the cognitive underpinnings of this state of "physical readiness" to approach ingroup and avoid outgroup members are discussed.     

When Me versus You Becomes Us versus Them: How Intergroup Competition Shapes Ingroup Psychology

Throughout evolutionary history, intergroup competition has been an influential part of social life. Although the topic has received substantial empirical attention among social psychologists, the majority of that work has focused on how ingroup and outgroup members regard one another. Only recently have researchers begun examining how intergroup rivalry changes that way that ingroup members perceive and relate to one another. New findings suggest that a variety of within‐group processes are influenced by the presence of a rival outgroup. In general, altruistic cooperation and prosocial motives increase among ingroup members when their group competes against another. The relationship between leaders and followers also shifts in response to intergroup rivalry: rather than wielding their power for selfish purposes, leaders prioritize the needs of their group. On the flip side, followers’ choice of leader changes, preferring males during times of intergroup competition but females in the absence of competition. Given the substantial impact of intergroup competition on ingroup processes, future research should continue to deepen the field’s knowledge of this topic. Additionally, the scope of research should be broadened to capture the effect of intergroup competition on ingroup dynamics, such as performance and group outcomes.     

United we win,divided we fail? Effects of cognitive merger representations and performance feedback on merging groups

Research has shown that cognitive representations of mergers influence intergroup evaluations. This paper extends this research by studying how cognitive representations of mergers (one group, dual identity, and two groups) interact with performance feedback (success and failure) to affect intergroup evaluations. Two competing hypotheses were tested, which made different predictions in case of superordinate group salience combined with subgroup salience after merger failure: The subgroup‐salience‐hypothesis predicts that subgroup salience during a merger generally results in pre‐merger ingroup bias toward the pre‐merger outgroup (i.e., two groups and dual identity). The superordinate‐ salience‐hypothesis predicts that subgroup salience only results in pre‐merger ingroup bias if superordinate group salience is low (i.e., two groups). Both hypotheses predict low levels of ingroup bias after merger success. Study 1 confirmed the second hypothesis using a 3 (merger representation: one group, dual identity, and two groups) × 2 (merger feedback: failure and success) design with interacting groups. Study 2 replicated the results in an adapted minimal group paradigm. Copyright © 2007 John Wiley & Sons, Ltd.     

Social categorization and power differentials in group relations

This study investigated the independent effects of power differentials on intergroup behaviour. Using a variant of Tajfel's minimal group paradigm (Tajfel and Turner, 1979), subjects were arbitrarily categorized into groups of differing power (0-100 per cent) at two levels of salience. Subjects were asked to distribute resources to ingroup and outgroup others using Tajfel's matrices. Intergroup perceptions, group identifications and self-reported strategies constituted our other dependent measures. Minimal group results, replicated in equal power conditions, were systematically eliminated in unequal power conditions on the matrix measures but not on the intergroup perception measures. Dominant group members were more discriminatory, felt more comfortable and satisfied than subordinate group members. Though consistent with Social Identity Theory (Tajfel and Turner, 1979), results suggest we may also have identified boundary conditions for minimal group discrimination. Without power, social categorization does not lead to effective discrimination.
