Varieties of groups and the perception of group entitativity.

Three studies examined perceptions of the entitativity of groups. In Study 1 (U.S.) and Study 2 (Poland), participants rated a sample of 40 groups on 8 properties of groups (e.g., size, duration, group member similarity) and perceived entitativity. Participants also completed a sorting task in which they sorted the groups according to their subjective perceptions of group similarity. Correlational and regression analyses were used to determine the group properties most strongly related to entitativity. Clustering and multidimensional scaling analyses in both studies identified 4 general types of groups (intimacy groups, task groups, social categories, and loose associations). In Study 3, participants rated the properties of groups to which they personally belonged. Study 3 replicated the results of Studies 1 and 2 and demonstrated that participants most strongly valued membership in groups that were perceived as high in entitativity.

Perceived entitativity, stereotype formation, and the interchangeability of group members.

The authors investigated the effects of perceived entitativity of a group on the processing of behavioral information about individual group members and the extent to which such information was transferred to other group members. The results of 3 experiments using a savings-in-relearning paradigm showed that trait inferences about a group member, based on that member's behavior, were stronger for low entitative groups and for collections of individuals. However, the transference of traits from 1 group member to other members of the group was stronger for high entitative groups. These results provide strong evidence that the perception of high entitativity involves the abstraction of a stereotype of the group and the transfer of that stereotype across all group members. Implications for group impression formation and stereotyping are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Birds of a feather and birds flocking together: Physical versus behavioral cues may lead to trait- versus goal-based group perception.

Entitativity perception refers to the perception of a collection of individuals as a group. The authors propose 2 perceptual-inferential bases of entitativity perception. First, perceivers would expect a collection of individuals with similar physical traits to possess common psychological traits. Second, perceivers watching a group of individuals engage in concerted behavior would infer that these individuals have common goals. Thus, both similarity in physical traits (e.g., same skin color) and concerted collective behavior (e.g., same movement) would evoke perception of group entitativity. Results from 5 experiments show that same group movement invariably leads to common goal inferences, increased perceived cohesiveness, and increased perceived entitativity. Moreover, same skin color evokes inferences of group traits and increases perceived homogeneity and perceived entitativity but only when skin color is diagnostic of group membership.

Group entitativity and group perception: Associations between physical features and psychological judgment.

Two experiments tested whether the perceived entitativity of groups (i.e., cohesiveness) influences judgments about those groups, in terms of both their observable physical properties and underlying psychological traits. Entitativity was manipulated with groups whose members were similar or dissimilar in skin color. Experiment 1 demonstrated that beliefs about entitativity elicited more accurate judgments of skin color for entitative than nonentitative social groups, although memory for individual members of entitative groups was relatively impoverished. Experiment 2 revealed that entitative groups were viewed as not only physically similar but also psychologically homogeneous and elicited strong negative trait and behavioral judgments. Together, these findings suggest that physical properties (e.g., similarity) can create perceptions of psychological "groupness" that have important consequences for group perception.

The Impact of Perceived Loafing and Collective Efficacy on Group Goal Processes and Group Performance

This paper presents two studies investigating the influence of social perceptions (perceived loafing, collective efficacy, and cohesion) on group goal processes (difficulty and commitment) and group performance. The role of group goal processes as mediators of the relationships between social perception variables and group performance was also tested. The first study involved a sample of 247 college students in 59 groups working on a team interdependent, divisible academic task. Results supported all but one hypothesis. The mediation hypothesis was not supported as both group goal and social perception variables related similarly to group performance. The second study employed a different design to address some limitations of the first study and to extend those findings. Results from the second study, using 383 college students in 101 groups, were consistent with Study 1 with two exceptions. First, the mediation hypothesis was supported in Study 2, replicating the findings of Klein and Mulvey (1995). Second, anticipated lower effort and the sucker effect, additional intervening variables examined in Study 2, partially mediated the relationship between perceived loafing and collective goal difficulty as hypothesized.

Stereotype formation and endorsement: The role of implicit theories.

Five experiments supported the hypothesis that peoples' implicit theories about the fixedness versus malleability of human attributes (entity versus incremental theories) predict differences in degree of social stereotyping. Relative to those holding an incremental theory, people holding an entity theory made more stereotypical trait judgments of ethnic and occupational groups (Experiments 1, 2, and 5 ) and formed more extreme trait judgments of novel groups ( Experiment 3 ). Implicit theories also predicted the degree to which people attributed stereotyped traits to inborn group qualities versus environmental forces (Experiment 2). Manipulating implicit theories affected level of stereotyping (Experiment 4), suggesting that implicit theories can play a causal role. Finally, implicit theories predicted unique and substantial variance in stereotype endorsement after controlling for the contributions of other stereotype-relevant individual difference variables (Experiment 5). These results highlight the importance of people's basic assumptions about personality in stereotyping. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

How people explain actions performed by groups and individuals.

The authors explore whether people explain intentional actions performed by groups differently from actions performed by individuals. A theoretical framework is offered that distinguishes between 2 modes of explanation: the agent's reasons (beliefs or desires in light of which the agent decided to act) and causal histories of reasons (CHRs; factors that preceded and brought about the agent's reasons). The authors develop the hypothesis that people use more CHR explanations when explaining group actions than when explaining individual actions. Study 1 demonstrates this asymmetry. Studies 2 and 3 explore 2 necessary conditions for the asymmetry: that the group be perceived as an aggregate of individual actors rather than as a jointly acting group and that explainers have general information available about the group. Discussion focuses on people's perception of groups as entities and agents. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Can the absence of prejudice be more threatening than its presence? It depends on one's worldview.

The present research used validated cardiovascular measures to examine threat reactions among members of stigmatized groups when interacting with members of nonstigmatized groups who were, or were not, prejudiced against their group. The authors hypothesized that people's beliefs about the fairness of the status system would moderate their experience of threat during intergroup interactions. The authors predicted that for members of stigmatized groups who believe the status system is fair, interacting with a prejudiced partner, compared with interacting with an unprejudiced partner, would disconfirm their worldview and result in greater threat. In contrast, the authors predicted that for members of stigmatized groups who believe the system is unfair, interacting with a prejudiced partner, compared with interacting with an unprejudiced partner, would confirm their worldview and result in less threat. The authors examined these predictions among Latinas interacting with a White female confederate (Study 1) and White females interacting with a White male confederate (Study 2). As predicted, people's beliefs about the fairness of the status system moderated their experiences of threat during intergroup interactions, indicated both by cardiovascular responses and nonverbal behavior. The specific pattern of the moderation differed across the 2 studies. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Perspective-taking: Decreasing stereotype expression, stereotype accessibility, and in-group favoritism.

Using 3 experiments, the authors explored the role of perspective-taking in debiasing social thought. In the 1st 2 experiments, perspective-taking was contrasted with stereotype suppression as a possible strategy for achieving stereotype control. In Experiment 1, perspective-taking decreased stereotypic biases on both a conscious and a nonconscious task. In Experiment 2, perspective-taking led to both decreased stereotyping and increased overlap between representations of the self and representations of the elderly, suggesting activation and application of the self-concept in judgments of the elderly. In Experiment 3, perspective-taking reduced evidence of in-group bias in the minimal group paradigm by increasing evaluations of the out-group. The role of self- other overlap in producing prosocial outcomes and the separation of the conscious, explicit effects from the nonconscious, implicit effects of perspective-taking are discussed.

The dissection of selection in person perception: Inhibitory processes in social stereotyping.

Although people simultaneously belong to multiple social categories, any one of these competing representations can dominate the categorization process. It is surprising therefore to learn that only a few studies have considered the question of how people are categorized when multiple categorizations are available. In addition, relatively little is known about the cognitive mechanisms through which these categorization effects are realized. In the reported research, we attempted to extend recent ideas from work on selective attention to shed some light on these fundamental issues in social perception. Our basic contention was that following the initial identification of a person's applicable categories, the categorization process is driven by the interplay of both excitatory and inhibitory mechanisms. The results of 3 studies supported this contention. We discuss our findings in the wider context of contemporary issues in social stereotyping.

The spontaneous use of a group typology as an organizing principle in memory.

Five studies investigated the spontaneous use of group typology in encoding information about various social groups. Participants saw faces or behaviors along with a label indicating the group membership of the face or the behavior. Labels corresponded to 2 groups each of 3 group types (i.e., 2 intimacy groups, 2 task-oriented groups, and 2 social categories). Recognition results showed more within-group-type errors than between-group-types errors. A free-recall task replicated these results, as the sequence of remembering items showed that memory organization reflected the group typology. A final study investigated the effects of group typology on the speed and accuracy of category membership verification. Results demonstrate the spontaneous use of an implicit group typology and its influence on the cognitive organization of information about groups.

Neurocognitive underpinnings of face perception: Further evidence of distinct person and group perception processes.

A model of social perception is presented and tested. The model is based on cognitive neuroscience models and proposes that the right cerebral hemisphere is more efficient at processing combinations of features whereas the left hemisphere is superior at identifying single features. These processes are hypothesized to produce person and group-based representations, respectively. Individuating or personalizing experience with an outgroup member was expected to facilitate the perception of the individuating features and inhibit the perception of the group features. In the presented study, participants were asked to learn about various ingroup and outgroup targets. Later, participants demonstrated that categorization response speeds to old targets were slower in the left hemisphere than in the right, particularly for outgroup members, as predicted. These findings are discussed for their relevance to models of social perception and stereotyping. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

"Do I know you?": The role of significant others in general social perception.

This research used an idiographic method to examine the proposition that significant others are mentally represented as well-organized person categories that can influence social perception even more than representations of nonsignificant others, stereotypes, or traits. Together, Studies 1 and 2 showed that significant-other representations are richer, more distinctive, and more cognitively accessible than the other categories. Study 3 replicated the accessibility data and gauged inferential power by indirectly activating each category in a learning trial about a fictional person and then testing recognition memory. The results showed that participants made more category-consistent false-positive errors about targets who activated significant others vs. any other category. This constitutes the first experimental demonstration of transference and has implications both for social categorization and for basic personality processes.

Social Identity as Social Glue: The Origins of Group Loyalty.

In 3 experiments, the authors investigated the role of social identity in fostering group loyalty, defined as staying when members can obtain better outcomes by leaving their group. In Experiment 1, high (vs. low) identifiers expressed a stronger desire to stay in the group in the presence of an attractive (vs. unattractive) exit option. Experiments 2 and 3 replicated this basic finding and tested several explanations. The results suggest that high identifiers' group loyalty is better explained by an extremely positive impression of their group membership (group perception) than by a justification of previous investments in the group (self-perception) or their adherence to a nonabandonment norm (norm perception). Hence, social identity seems to act as social glue. It provides stability in groups that would otherwise collapse. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Team reflexivity, development of shared task representations, and the use of distributed information in group decision making.

Decision-making groups often exchange and integrate distributed information to a lesser extent than is desirable for high-quality decisions. One important reason for this lies in group members’ understanding of the decision task—their task representations—specifically the extent to which they understand the importance of exchange and integration of information. The authors hypothesized that a group’s development of a (shared) understanding of the information elaboration requirements of their task is influenced by collective reflection on the task. When not all group members initially realize the importance of information elaboration, team reflexivity increases the degree to which the group understands the importance of information elaboration. In an experiment, the authors showed that team reflection fostered the development of task representations emphasizing information elaboration and subsequent information elaboration and decision quality. When all members initially already held representations emphasizing information elaboration, team reflection promoted elaboration and performance to a lesser degree.

Personal beliefs and cultural stereotypes about racial characteristics.

Social stereotypes may be expressed as personal beliefs about the characteristics of a group or as beliefs about the predominant cultural view of a group. In a study with a full intergroup design, Black and White participants rated Black and White racial groups. Results supported 3 sets of predictions derived from a projection model of stereotyping. First, participants' personal beliefs predicted their ratings of cultural stereotypes even when the group averages of personal beliefs and cultural stereotypes were statistically controlled. Second, interrater agreement in stereotype ratings was substantial for both rating tasks. Third, members of both groups underestimated how favorably their own group was rated by members of their respective out-group. Implications of the findings for the mental organizations of stereotypes, their measurement, and their consequences for social behavior are discussed.

Social roles as mechanism for psychological need satisfaction within social groups.

The authors explored ways in which needs for autonomy and relatedness can be simultaneously met within the context of group life. Specifically, it was hypothesized that social role performances provide means of both expressing the self and connecting with group members. Consistent with the assumption that autonomy and relatedness are complementary rather than conflictual, these needs were positively correlated in all 5 studies. Consistent with the authors' assumption that these needs are both important, feelings of autonomy and relatedness in social roles independently predicted subjective well-being, as measured by concurrent (Studies 1 and 3), peer-report (Study 2), and longitudinal (Studies 4 and 5) methodologies. Study 5 showed that participants whose characteristics matched an assigned role experienced more autonomy and relatedness and thus more positive mood during a group task. Implications for optimal functioning in group contexts are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Party Over Policy: The Dominating Impact of Group Influence on Political Beliefs.

Four studies demonstrated both the power of group influence in persuasion and people's blindness to it. Even under conditions of effortful processing, attitudes toward a social policy depended almost exclusively upon the stated position of one's political party. This effect overwhelmed the impact of both the policy's objective content and participants' ideological beliefs (Studies 1-3), and it was driven by a shift in the assumed factual qualities of the policy and in its perceived moral connotations (Study 4). Nevertheless, participants denied having been influenced by their political group, although they believed that other individuals, especially their ideological adversaries, would be so influenced. The underappreciated role of social identity in persuasion is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

When dispositional and role power fit: Implications for self-expression and self–other congruence.

Integrating and extending the literatures on social power and person–environment fit, 4 studies tested the hypothesis that when people's dispositional beliefs about their capacity to influence others fit their assigned role power, they are more likely to engage in self-expression—that is, behave in line with their states and traits—thereby increasing their likelihood of being perceived by others in a manner congruent with their own self-judgments (i.e., self–other congruence). In Studies 1–3, dispositionally high- and low-power participants were randomly assigned to play a high- or low-power role in an interaction with a confederate. When participants' dispositional and role power fit (vs. conflicted), they reported greater self-expression (Study 1). Furthermore, under dispositional-role power fit conditions, the confederate's ratings of participants' emotional experiences (Study 2) and personality traits (Study 3) were more congruent with participants' self-reported emotions and traits. Study 4's results replicated Study 3's results using an implicit manipulation of power and outside observers' (rather than a confederate's) ratings of participants. Implications for research on power and person perception are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Conflict's consequences: Effects of social motives on postnegotiation creative and convergent group functioning and performance.

Two studies tested the effects of social motives during negotiation on postnegotiation group performance. In both experiments, a prosocial or a proself motivation was induced, and participants negotiated in 3-person groups about a joint market. In Experiment 1, groups subsequently performed an advertisement task. Consistent with the authors' predictions, results showed that proself groups performed worse on the convergent aspects of this task but better on the divergent aspects than prosocial groups. In Experiment 2, the authors manipulated social motive and negotiation (negotiation vs. no negotiation), and groups performed a creativity task (requiring divergent performance) or a planning task (requiring convergent performance). Proself groups showed greater dedication, functioned more effectively, and performed better than prosocial groups on the creativity task, whereas prosocial groups showed greater dedication, functioned more effectively, and performed better than proself groups on the planning task, and these effects only occurred when the task was preceded by group negotiation.
