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.

Us without them: Evidence for an intragroup origin of positive in-group regard.

Four experiments examined whether group formation and positive in-group regard require interaggregate comparison as the in-group-requires-an-out-group assumption of the metacontrast principle implies. The authors fostered novel social aggregates with or without a contrasting aggregate with which members could compare and varied intra-aggregate factors (interaction or interdependence). Regardless of whether interaggregate comparison was feasible, the intra-aggregate factors increased the perceived entitativity of the aggregate and positive regard toward the aggregate (i.e., social attraction and cooperation among members). Mediation analyses were consistent with the possibility that the intra-aggregate factors promoted entitativity, which in turn promoted in-group regard. These data suggest that group formation and in-group regard have intragroup origins and do not require comparison with a contrasting social aggregate.

Culture and group perception: Dispositional and stereotypic inferences about novel and national groups.

In 3 studies, the authors tested the hypothesis that Chinese participants would view social groups as more entitative than would Americans and, as a result, would be more likely to infer personality traits on the basis of group membership--that is, to stereotype. In Study 1, Chinese participants made stronger stereotypic trait inferences than Americans did on the basis of a target's membership in a fictitious group. Studies 2 and 3 showed that Chinese participants perceived diverse groups as more entitative and attributed more internally consistent dispositions to groups and their members. Guided by culturally based lay theories about the entitative nature of groups, Chinese participants may stereotype more readily than do Americans when group membership is available as a source of dispositional inference.

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)     

In the name of Mussolini: Explaining the schism in an Italian right-wing political party.

The authors present a study testing and refining the social psychological model of schism in groups (F. Sani, 2005) by applying it to the schism that occurred in Alleanza Nazionale--an Italian political party of the right--in 2003. The authors found that perceptions of identity subversion (a sense that the group essence has been undermined by a change made by the group majority) have negative effects on group identification and positive effects on aversive emotions (dejection, agitation, and anger). Perceived identity subversion also has a negative influence on perceived group entitativity, which in turn has positive effects on group identification. Finally, group identification has a negative impact, and aversive emotions have a positive impact, on schismatic intentions. The authors also found that the more those who oppose the change are seen as having the ability to voice their dissent, the less both the negative impact of group identification and the positive impact of aversive emotions on schismatic intentions.

What drives trust transfer from web to mobile payment services? The dual effects of perceived entitativity

Drawing from trust transfer theory, this study investigates cognitive trust and emotional trust transfer from web payment (WP) to mobile payment (MP) services with the emphasis on the effect of web–mobile payment relationship, namely, perceived entitativity. By conducting an online survey (n = 491), our study shows two key findings. First, cognitive trust and emotional trust can be transferred from WP to MP services, which, in turn, formulate intention to use MP services. Second, perceived entitativity not only increases cognitive trust and emotional trust in MP, but also enhances the transfer of cognitive trust and emotional trust from WP to MP services.     

Source entitativity and the elaboration of persuasive messages: The roles of perceived efficacy and message discrepancy.

Compared with nonentitative groups, entitative targets are considered to elicit more elaborative processing because of the singularity or unity they represent. However, when groups serve as sources of persuasive messages, other dynamics may operate. The current research suggests that entitativity is intrinsically linked to perceptions of a group’s efficacy related to the advocacy, and this efficacy combines with the position of the appeal to determine message elaboration. When messages are counterattitudinal, entitative (efficacious) sources should elicit greater processing than nonentitative groups because of concern that the entitative sources may be more likely to bring about the negative outcomes proposed. However, when appeals are proattitudinal, sources low in entitativity (nonefficacious) should initiate more elaboration due to concern that they may be unlikely to facilitate the positive outcomes proposed. These hypotheses were supported in a series of studies. Preliminary studies established the entitativity–efficacy relation (Studies 1A and 1B). Primary persuasion studies showed that manipulations of source entitativity (Studies 2 and 3) and source efficacy (Studies 4A and 4B) have opposite effects on processing as a function of message discrepancy.
