Group entitativity and similarity: Their differing patterns in perceptions of groups

Three studies were conducted to investigate the relation between perceptions of group entitativity and group similarity. The first two studies tested whether entitativity and similarity would be perceived differently in participants' ingroups and outgroups. Across several different group types, we found that, in comparison to outgroups, ingroups were perceived to be relatively more entitative than outgroups, whereas outgroup members were perceived to be highly similar in comparison to ingroup members. The results of Study 3 showed that manipulation of group entitativity influenced perceptions of group entitativity but not of group similarity, whereas manipulation of similarity influenced perceptions of group similarity but not of group entitativity. The results of these studies provide support for the contention that entitativity and similarity are distinct (though related) concepts that function differently in group perception.

Uncertainty, entitativity, and group identification

Two studies examined the effects of self-uncertainty and ingroup entitativity on group identification. From uncertainty reduction theory (Hogg, 2000), it was hypothesized that people would identify most strongly with their group if they felt self-conceptually uncertain and the group was highly entitative. Study 1 was a field experiment (N = 114) in which the perceived entitativity of participants’ political party was measured, and self-uncertainty was primed (high vs. low). Study 2 was a laboratory experiment (N = 89) with ad hoc non-interactive groups. Uncertainty was primed as in Study 1, but perceived entitativity was manipulated. In both cases the dependent variable was a multi-item measure of group identification. The hypothesis was fully supported in both studies—participants identified more strongly when they were uncertain and the group was highly entitative. Implications of this research for the role of uncertainty and social identity in extremism, orthodoxy, and ideological belief systems are discussed.     

Implicit theories about groups and stereotyping: the role of group entitativity

The consequences of holding an entity (i.e., the belief that a group's characteristics are fixed) or incremental (i.e., the belief that a group's characteristics are malleable) implicit theory about groups was examined for stereotyping and perceptions of group entitativity. Two studies showed that implicit theories about groups affect stereotyping by changing perceptions of group entitativity. Study 1 found that entity theorists were more likely to stereotype than incremental theorists and that perception of group entitativity significantly accounted for this relation. In Study 2, implicit theories of groups were manipulated via instruction set and entity theorists stereotyped more and perceived groups as more entitative than incremental theorists. Again, the effect of implicit theory was significantly, although partially, mediated by perceptions of group entitativity. The roles of implicit theories about groups and perceptions of group entitativity are discussed regarding stereotyping.     

Antecedents of entitativity in categorically and dynamically construed groups

The extent to which a set of people is perceived as a meaningful group, as one entity, is called entitativity. In this paper, we propose that there are two qualitatively different group construals, or ways of thinking, about groups: as dynamic groups or as categorical groups. Two experiments investigated this distinction. An analogy was used to induce these construals by having participants think of the same group (the group “bees”) either dynamically (as the interacting members of a hive) or categorically (as the members of the species). We then gave participants information about a social group and assessed the impact of the construal manipulation on how that information was processed. Study 1 showed that perceivers recall and report different perceptual cues (similarity and interaction characteristics, respectively) when groups are thought of in these different ways. Study 2 showed that judgments of entitativity are differentially based on a group's similarity versus interaction under these different group construals. The results suggest that group construals change the properties on which entitativity is based. Copyright © 2008 John Wiley & Sons, Ltd.     

Movement synchrony and perceived entitativity

Movement synchrony has been theoretically linked to the emergence of a social unit. To empirically investigate whether similar movement rhythms are an antecedent of perceived entitativity, movement rhythms were experimentally manipulated in four studies. Using this novel approach, stick figures waving in synchrony were found to be rated higher on entitativity than stick figures waving in different rhythms (Study 1), and this effect was extended to interactional synchrony, where different movements are performed in the same rhythm (Study 2). Objective differences in movement rhythms are linearly related to ratings of perceived entitativity, and this relationship is partially mediated by the subjectively perceived similarity of movement rhythms (Study 3). These results also held for entitativity judgments for videotaped individuals waving rhythmically (Study 4). These results support the hypothesis that movement rhythms are an important source of information which observers use to infer the extent to which individuals are a social unit.     

Entitativity,identity, and the fulfilment of psychological needs

Social groups provide many benefits to the individual and some groups are better able to meet the needs of their group members. The current research examines the impact of perceived entitativity on the degree to which groups are able to fulfil the psychological needs of individual members. Participants listed ingroups based on the group typology of Lickel et al. (2000) and rated characteristics of the group, level of identification, and the degree to which the group met a series of needs. The results indicate that increased entitativity predicts greater perceived relative need fulfilment and that this effect is mediated by level of identification with the group. These results extend our understanding of the functions that different group types serve and the consequences of ingroup entitativity perceptions for the individual.     

Are Women Perceived as Engaging in More Maladaptive Worry Than Men? A Status Interpretation

Studies 1 and 2 addressed people's perceptions of women's and men's overall maladaptive worry. In Study 1, participants rated how they perceive women's and men's worry in general. In Study 2, participants rated the worry of either a woman or a man whom they know well. As expected in both studies, participants perceived women as experiencing more maladaptive worry than men. A second objective was to compare people's perceptions of women's and men's worry to their perceptions of low- and high-status individuals' worry to determine if a status model can account for the perception that women worry more than men. In Study 3, participants were presented a minimal instantiation of status (Conway, Pizzamiglio, & Mount, 1996). As expected, participants perceived low-status individuals as experiencing more maladaptive worry than high-status individuals. Findings are discussed in terms of gender stereotypes and theoretical models of gender.     

Intuitive theories of group types and relational principles

Three studies investigated perceivers’ beliefs about the principles by which different kinds of social groups govern interactions among group members. In Study 1, participants rated a sample of 20 groups on a set of group properties, including measures of relational principles used within groups. Results showed that people believe that interactions in different types of groups are governed by different blends of relational principles unique for each type of group. Study 2 experimentally demonstrated that perceivers could use minimal group property characteristics of different types of groups (i.e., extent of group member interaction, group size, duration, and permeability) to make inferences about the relational principles used in different types of groups. Study 3 demonstrated that relational style information influences people’s judgments of a group’s entitativity and collective responsibility.     

We are one and I like it: The impact of ingroup entitativity on ingroup identification

It is argued that the entitativity of the ingroup moderates the level of identification with the ingroup. Specifically, that high levels of entitativity are conducive to strong identification, whereas low levels of entitativity reduce identification with the ingroup. These hypotheses were tested across four studies using the European Union (EU) as the reference group. The four studies manipulated four different factors that, according to Campbell (1958), impact on group entitativity: common fate (Study 1), similarity (Study 2), salience (Study 3), and boundedness (Study 4). Across the four studies, we found evidence for the impact of these factors on the level of identification with the EU among European citizens holding moderate attitudes toward the EU but not (or much less) for citizens holding more extreme attitudes towards the EU. Mediational analyses further confirmed the viability of an entitativity‐based interpretation of the impact of the manipulations on the level of identification. The findings are discussed in light of the current debate on the concept of entitativity, the motives for social identification, and the reduction of ingroup bias.

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 fundamentality of group principles and perceived group entitativity

We argue that the level of consensus about a set of social identity principles, and their perceived fundamentality, can influence the degree to which members perceive their group as an entity. This idea was explored through an experiment in which participants judged the entitativity of specific (in)groups on the basis of the distribution of the opinions held by their members about three identity-related principles that participants had previously rated for fundamentality. The results demonstrated that the more fundamental a principle was judged to be in comparison to other principles, the more important consensus about that principle was for producing group entitativity, relative to consensus about other principles.     

Physical pain induces negative person perception

We examined the hypothesis that pain increases negative person perception of irrelevant others in both medical and laboratory settings in three studies. Patients perceived a nurse as more negative if the injection they received from the nurse produced more pain (Pilot Study). Patients rated neutral faces as more negative after receiving an injection than before it (Study 1). Participants who performed a painful cold pressor task rated neutral faces as more negative than a control group, but this effect only appeared for those with low perceived social support (Study 2). These findings suggest that one's experience of physical pain may be metaphorically transferred to perceptions of completely irrelevant others, inducing negative interpersonal perception. And perceived social support can ameliorate the negative effect.     

Why do we punish groups? High entitativity promotes moral suspicion

People typically take a moral deservingness perspective when deciding on appropriate punishment for intentional wrongdoings committed by individuals. Considerably less is known about how people reason about wrongdoings committed by groups, even though there are fundamental differences in how people perceive individuals versus groups. The present research examined perceived entitativity, the degree to which a group is perceived to be a unified, single agent, as a potential determinant of moral reasoning about transgressions committed by groups. We found that participants recommended more severe punishments for high entitativity (vs. low entitativity) perpetrator groups, particularly in the presence of morally mitigating circumstances that typically lessen punitiveness. This effect was mediated by perceptions of greater moral accountability in high-entitativity groups. Thus, justice is not equal for all groups. Implications for retributive justice and the criminal justice system are discussed.     

The roles of ingroup identification and outgroup entitativity in intergroup retribution

A new aspect of intergroup conflict was investigated- vicarious retribution-in which neither the agent of retribution nor the target of retribution are directly involved in the initial intergroup provocation. The underlying processes involved in vicarious intergroup retribution were tested correlationally (Study 1) and experimentally (Study 2). Both ingroup identification and outgroup entitativity predict the degree of vicarious retribution. In both studies, there was evidence of motivated cognition, specifically that highly identified individuals perceived the outgroup as higher in entitativity than individuals low in identification. Structural equation modeling demonstrated that part of the effect of identification on retribution against the outgroup was mediated through perceptions of entitativity.     

Perceived ingroup entitativity and intergroup bias: an interconnection of self and others

Campbell's (1958) concept of ingroup entitativity is reformulated as a perceived interconnection of self and others. A 2 (intergroup relations: competitive, neutral)×3 (intragroup interaction: low, medium, high) between-subjects design was used to examine (1) the effects of intergroup and intragroup relations on perceived ingroup entitativity and (2) the relation between ingroup entitativity and intergroup bias. Regardless of the relations between groups, members who experienced intragroup interaction had stronger perceptions of ingroup entitativity and stronger representations of the aggregate of ingroup and outgroup members as two separate groups than members who lacked intragroup interaction. Furthermore, perceptions of ingroup entitativity mediated the effect of the salience of the intergroup boundary on behavioral intergroup bias. These results call into question the ‘intergroup’ nature of group based phenomena. An ingroup entitativity framework is presented that locates the source of group-based phenomena (e.g. intergroup bias) in intragroup processes. Copyright © 1998 John Wiley & Sons, Ltd.     

Perceiving one's nation: entitativity, agency and security in the international arena

The perception of groups as real entities rather than mere aggregates of individuals has important consequences on intergroup relations. Social psychological research, in fact, shows that it affects stereotyping, identification process, and intergroup bias. Previous research has also shown that group entitativity is not a positive or negative group attribute per se; rather, it depends on the context and the relationship between the perceiver and the group. While enhancing entitativity leads to worse expectations about the out‐group actions, high entitativity is a valued characteristic when associated with an ally or with the in‐group. Indeed, enhancing in‐group entitativity leads to stronger in‐group identification. The specific reasons for why this is the case, however, remain to be ascertained. What is good about in‐group entitativity? In the present contribution we propose that in‐group entitativity may lead to perceive the group as a real entity provided with intentions and capacity for planned actions, notably ensuring the safety of its members by protecting them against external threats. We report two correlational studies conducted with American citizens (Study 1) and Italian citizens (Study 2), showing that in‐group entitativity is associated with a higher level of identification, attribution of intentionality, and perceived security provided by the in‐group. These findings were replicated in a third study—conducted with a role‐play method on a fictitious scenario—in which entitativity was manipulated rather than measured. Study 3 also shows that artificially increasing the perception of in‐group entitativity enhances perceived safety in an international context and reduces the perception of threat from an out‐group. Findings are discussed in terms of possible implications for intergroup and international relations.     

Perceived collective continuity: seeing groups as entities that move through time

This paper presents two studies, conducted in two different countries, investigating perceptions of ingroups as enduring, temporally persistent entities, and introduces a new instrument measuring ‘perceived collective continuity’ (PCC). In Study 1 we show that perceptions of ingroup continuity are based on two main dimensions: perceived cultural continuity (perceived continuity of norms and traditions) and perceived historical continuity (perceived interconnection between different historical ages and events). This study also allows the construction of an internally consistent PCC scale including two subscales tapping on these two dimensions. Study 2 replicates findings from the first study; it also reveals that PCC is positively correlated to a set of social identity-related measures (e.g., group identification and collective self-esteem), and that its effects on these measures are mediated by perceived group entitativity. Overall, these two studies confirm that PCC is an important theoretical construct, and that the PCC scale may become an important instrument in future research on group processes and social identity.

The Role of Face Familiarity in Judgments of Personality and Intelligence

Personality judgments based on facial features are a common occurrence. The face familiarity overgeneralization hypothesis states that people make judgments of unknown faces based on their similarity to known faces. However, there is a dearth of research regarding how face familiarity relates to perceptions of personality and intelligence in strangers. The current article used two studies to provide evidence for the relationship between face familiarity and judgments of personality and intelligence. Study 1 showed that photographs perceived as familiar by one set of participants were rated more positively regarding personality and intelligence by a second group of participants. Study 2 found that high perceived familiarity resulted in positive judgments of personality and intelligence, whereas familiarity based on exposure did not. These findings indicate both that perceived familiarity significantly impacts positive judgments of personality and intelligence and that the face familiarity overgeneralization hypothesis is a useful framework for this area of research.     

Self-regulation and the extended now: controlling the self alters the subjective experience of time

These studies investigated self-regulation and subjective experience of time from the perspective of the regulatory resource model. Studies 1-2 showed that participants who were instructed to regulate their emotions while viewing a film clip perceived that the film lasted longer than participants who did not regulate their emotions. In Study 3, participants provided time estimates during a resource-depleting or nondepleting task. Subsequent task persistence was measured. Time perceptions mediated the effect of initial self-regulation on subsequent self-regulated performance. In Study 4, participants performed either a resource-depleting or a nondepleting thought-listing task and then performed a different regulatorytask. Compared with nondepleted participants, depleted participants persisted less on the 2nd task but estimated that they had persisted longer. Subjective time estimates statistically accounted for reduced persistence after depletion. Together, results indicate people believe that self-regulatory endeavors last overly long, a belief that may result in abandonment of further self-control.
