Groups as epistemic providers: need for closure and the unfolding of group-centrism.

Theory and research are presented relating the need for cognitive closure to major facets of group behavior. It is suggested that a high need for closure, whether it is based on members' disposition or the situation, contributes to the emergence of a behavioral syndrome describable as group-centrism--a pattern that includes pressures to opinion uniformity, encouragement of autocratic leadership, in-group favoritism, rejection of deviates, resistance to change, conservatism, and the perpetuation of group norms. These theoretical predictions are borne out by laboratory and field research in diverse settings.

Relevance override: on the reduced impact of "cues" under high-motivation conditions of persuasion studies.

This research addressed the reduced impact of cues under high processing motivation of persuasion experiments. The results of 3 studies suggested that such reduced impact is due to a relevance override whereby any more subjectively relevant information swamps the effects of any less subjectively relevant information, given the recipient's sufficient motivation to process both. Because, in much persuasion research, cues may have been perceived as less relevant to the attitudinal judgments than message arguments, the relevance override hypothesis provides a general explanation of the reduced cue effect.

The social cognition of immigrants' acculturation: effects of the need for closure and the reference group at entry.

Three studies found support for the notion that immigrants' acculturation to the host culture is interactively determined by their need for cognitive closure (A. W. Kruglanski & D. M. Webster, 1996) and the reference group they forge on their arrival. If such reference group is fashioned by close social relations with coethnics, the higher the immigrants' need for closure, the weaker their tendency to assimilate to the new culture and the stronger their tendency to adhere to the culture of origin. By contrast, if the reference entry group is fashioned by close relations with members of the host country, the higher their need for closure, the stronger their tendency to adapt to the new culture and the weaker their tendency to maintain the culture of origin. These findings obtained consistently across 3 immigrant samples in Italy, 1 Croatian and 2 Polish, and across multiple different measures of acculturation.

Autocracy bias in informal groups under need for closure.

Two experiments investigated the tendency of groups with members under high (vs. low) need for cognitive closure to develop an autocratic leadership structure in which some members dominate the discussion, constitute the "hubs" of communication, and influence the group more than other members. The first experiment found that high (vs. low) need for closure groups, as assessed via dispositional measure of the need for closure, manifested greater asymmetry of conversational floor control, such that members with autocratic interactional style were more conversationally dominant and influential than less autocratic members. The second experiment manipulated the need for closure via time pressure and utilized a social network analysis. Consistent with expectation, groups under time pressure (vs. no pressure) showed a greater asymmetry of participation, of centrality, and of prestige among the group members, such that the more focal members were perceived to exert the greater influence over the groups' decisions.

When similarity breeds content: need for closure and the allure of homogeneous and self-resembling groups.

Four studies explored the relation between members' need for cognitive closure and their feelings toward groups. It was found that high (vs. low) need for closure individuals liked in-groups and out-groups more as function of the degree to which their membership was perceived as homogeneous (Studies 1-4), provided it was also self-similar (Studies 3 and 4). These results are discussed in terms of the relation between need for closure and homogeneous (vs. heterogeneous) groups' apparent potential as "closure providers."

A cross-cultural study of the Need for Cognitive Closure Scale: comparing its structure in Croatia, Italy, USA and The Netherlands.

This study was designed to compare the factor structure of Need for Closure Scale (NFCS) as it emerges from three European samples (Croatia, Italy and The Netherlands) to the structure emerging from a USA sample, and to test the invariance of the structure of the scale both across three European contexts and across European and US samples. This comparison was conducted to examine the generalizability of results obtained with the NFCS across cultures. The sample sizes employed in this study range from 201 (Croatia) to 418 (Italy) participants. First- and second-order confirmatory factor analysis and multiple-group measurement invariance tests were performed using the LISREL-8 program (Jöreskog and Sörbom, 1993). The analyses revealed that the factor structure of the scale was invariant across all samples, and that the best fitting model was one with two latent second-order factors, thus confirming results of previous studies (Kruglanski et al., 1997; Neuberg, Judice, & West, 1997).

The statistical analysis of data from small groups.

The authors elaborate the complications and the opportunities inherent in the statistical analysis of small-group data. They begin by discussing nonindependence of group members' scores and then consider standard methods for the analysis of small-group data and determine that these methods do not take into account this nonindependence. A new method is proposed that uses multilevel modeling and allows for negative nonindependence and mutual influence. Finally, the complications of interactions, different group sizes, and differential effects are considered. The authors strongly urge that the analysis model of data from small-group studies should mirror the psychological processes that generate those data.
