Social categorization and group‐motivated interindividual–intergroup discontinuity

Research on the interindividual–intergroup discontinuity effect has demonstrated that intergroup relations are often less cooperative than interindividual relations. The aim of the present paper is to test whether mere social categorization suffices to create a group‐motivated discontinuity effect. In two experiments, we manipulated actors' personal versus social identity salience, whereas controlling for actors' outcome independence (1 : 1) versus interdependence (3 : 3). Making actors' social identity salient using a minimal group treatment was sufficient to increase defection in a Prisoner's Dilemma Game, irrespective of whether this was in an interindividual or intergroup interaction (Experiment 1). Using a Mutual Fate Control matrix in Experiment 2, results indicate that this effect can be attributed to actors' increased motivation to maximize relative differences to outgroup opponents under social identity salience.

Social categorization and intergroup behaviour

The aim of the studies was to assess the effefcs of social categorization on intergroup behaviour when, in the intergroup situation, neither calculations of individual interest nor previously existing attitudes of hostility could have been said to have determined discriminative behaviour against an outgroup. These conditions were satisfied in the experimental design. In the first series of experiments, it was found that the subjects favoured their own group in the distribution of real rewards and penalities in a situation in which nothing but the variable of fairly irrelevant classification distinguished between the ingroup and the outgroup. In the second series of experiments it was found that: 1) maximum joint profit independent of group membership did not affect significantly the manner in which the subjects divided real pecuniary rewards; 2) maximum profit for own group did affect the distribution of rewards; 3) the clearest effect on the distribution of rewards was due to the subjects' attempt to achieve a maximum difference between the ingroup and the outgroup even at the price of sacrificing other ‘objective’ advantages. The design and the results of the study are theoretically discussed within the framework of social norms and expectations and particularly in relation to a ‘generic’ norm of outgroup behaviour prevalent in some societies.     

Negational categorization and intergroup behavior

Individuals define themselves, at times, as who they are (e.g., a psychologist) and, at other times, as who they are not (e.g., not an economist). Drawing on social identity, optimal distinctiveness, and balance theories, four studies examined the nature of negational identity relative to affirmational identity. One study explored the conditions that increase negational identification and found that activating the need for distinctiveness increased the accessibility of negational identities. Three additional studies revealed that negational categorization increased outgroup derogation relative to affirmational categorization and the authors argue that this effect is at least partially due to a focus on contrasting the self from the outgroup under negational categorization. Consistent with this argument, outgroup derogation following negational categorization was mitigated when connections to similar others were highlighted. By distinguishing negational identity from affirmational identity, a more complete picture of collective identity and intergroup behavior can start to emerge.     

Personality and team performance: a meta‐analysis

Using a meta‐analytical procedure, the relationship between team composition in terms of the Big‐Five personality traits (trait elevation and variability) and team performance were researched. The number of teams upon which analyses were performed ranged from 106 to 527. For the total sample, significant effects were found for elevation in agreeableness (ρ = 0.24) and conscientiousness (ρ = 0.20), and for variability in agreeableness (ρ = ?0.12) and conscientiousness (ρ = ?0.24). Moderation by type of team was tested for professional teams versus student teams. Moderation results for agreeableness and conscientiousness were in line with the total sample results. However, student and professional teams differed in effects for emotional stability and openness to experience. Based on these results, suggestions for future team composition research are presented.

A meta‐analysis of the effects of speakers' accents on interpersonal evaluations

This paper reports a meta‐analysis of the empirical literature on the effects of speakers' accents on interpersonal evaluations. Our review of the published literature uncovered 20 studies that have compared the effects of standard accents (i.e., the accepted accent of the majority population) versus non‐standard accents (i.e., accents that are considered foreign or spoken by minorities) on evaluations about the speakers. These 20 studies yielded 116 independent effect sizes on an array of characteristics that were selected by the original researchers. We classified each of the characteristics as belonging to one of three domains that have been traditionally discussed in this area, namely status (e.g., intelligence, social class), solidarity (trustworthiness, in‐group–out‐group member), and dynamism (level of activity and liveliness). The effect was particularly strong when American Network accented speakers were compared with non–standard‐accented speakers. These results underscore prior research showing that speakers' accents have powerful effects on how others perceive them. These and other results are discussed in the context of the literature along with implications for future research in this area. Copyright © 2011 John Wiley & Sons, Ltd.     

Familiarity and categorization in intergroup behavior

Several studies have shown that social categorization into groups, unaffected by other variables such as own interest, interpersonal relations, conflict of interests, previous hostility, etc., was a sufficient condition to induce discrimination against an outgroup. The purpose of the present study was to test the hypothesis that the subjects' uncertainty and insecurity in a novel situation was, at least in part, responsible for this phenomenon. Two groups of subjects were tested: one group was made familiar with the social and physical setting of the experiment in a situation closely resembling the actual experiment, and came back for a second session in which the actual experiment was conducted; the second group came only for the actual experimental session. The results clearly indicate that, contrary to the hypothesis, the “familiar” group engaged in more out-group discrimination than the “unfamiliar” one. The theoretical and methodological implications of this finding are discussed.     

Parenting and self‐regulation in preschoolers: a meta‐analysis

A meta‐analysis of 41 studies was conducted to examine the strength of the relation between parenting (positive control, negative control and responsiveness) and self‐regulation in preschoolers. Results revealed significant associations between both types of parental control and self‐regulation, with effect sizes being small in magnitude. There was no significant association between self‐regulation and responsiveness. The strength of the association between parenting and self‐regulation varied with different conceptualizations of self‐regulation; positive and negative control were associated with child compliance, but not with inhibition and emotion regulation.

Protestant work ethic's relation to intergroup and policy attitudes: A meta‐analytic review

The Protestant work ethic (PWE), the belief that hard work leads to success, is prevalent in many cultures and has been related to negative attitudes toward disadvantaged groups (prejudice) and social policies targeting them. Given recent theorizing and findings suggesting that PWE is not necessarily associated with prejudice among all people or in all contexts, this meta‐analysis examined the direction and strength of PWE's relation to prejudice (37 eligible studies) and policy attitudes (16 studies) among published and unpublished studies across 38 years. Results revealed not only significant positive relationships between PWE and both types of intergroup attitudes but also significant moderators of these relationships. There were significantly larger effect sizes for PWE's relationship with both prejudice and policy attitudes among samples in Western countries (Canada, England, New Zealand, USA), and marginally significantly larger effect sizes for PWE's relationship with both types of attitudes the older the mean age of the sample (within Western countries). PWE's relationship with intergroup attitudes also varied by the target group of the attitudes. Findings support a more nuanced view of PWE's relationship with intergroup attitudes, suggesting that PWE does not always promote greater prejudice; rather its consequences are culture and context bound.

How to do a meta‐analysis

Meta‐analysis is a statistical tool for estimating the mean and variance of underlying population effects from a collection of empirical studies addressing ostensibly the same research question. Meta‐analysis has become an increasing popular and valuable tool in psychological research, and major review articles typically employ these methods. This article describes the process of conducting meta‐analysis: selecting articles, developing inclusion criteria, calculating effect sizes, conducting the actual analysis (including information on how to do the analysis on popular computer packages such as IBM SPSS and R) and estimating the effects of publication bias. Guidance is also given on how to write up a meta‐analysis.     

Anticipated outgroup evaluations and intergroup bias

A study is reported that tests the hypothesis that group members exhibit intergroup bias in response to the belief that outsiders will discriminate against them. To this end, two experimental conditions are included in which subjects anticipate either biased evaluations or fair evaluations respectively. In a control condition, subjects do not expect to be evaluated from an external source. Results indicated, as expected, that those who anticipated biased evaluations from an outgroup exhibited bias themselves, while those who anticipated fair evaluations exhibited outgroup favouritism. The fact that control subjects exhibited the same degree of bias as those who anticipated biased evaluations from the outgroup poses some difficulties for the hypothesized connection between anticipated discrimination and intergoup bias. Thus, it appears that intergroup bias is the rule and not the exception in an intergroup context. Nevertheless, it is clear that anticipated evaluations of outgroup members can effect intergroup bias.     

Social categorization and similarity in intergroup behaviour

The present study is one of a series exploring the role of social categorization in intergroup behaviour. It has been found in our previous studies that in ?minimal' situations, in which the subjects were categorized into groups on the basis of visual judgments they had made or of their esthetic preferences, they clearly discriminated against members of an outgroup although this gave them no personal advantage. However, in these previous studies division into groups was still made on the basis of certain criteria of ?real' similarity between subjects who were assigned to the same category. Therefore, the present study established social categories on an explicitly random basis without any reference to any such real similarity. It was found that, as soon as the notion of ?group' was introduced into the situation, the subjects still discriminated against those assigned to another random category. This discrimination was considerably more marked than the one based on a division of subjects in terms of interindividual similarities in which the notion of ?group' was never explicitly introduced. In addition, it was found that fairness was also a determinant of the subjects' decisions. The results are discussed from the point of view of their relevance to a social-cognitive theory of intergroup behaviour.     

Examining differences in minority versus majority preschoolers on social categorization and perceived intergroup distance

We examined the differences between majority and minority children (i.e., group membership) on racial categorization and perceived cultural distance, among 4‐ to 6‐year‐old children, in low diversified schools. We used a spontaneous social categorization task using pictures of children from three different racial groups broadly represented in France (Europeans, Black‐, and North‐Africans), and an evaluation of the perceived cultural distance between participants' in‐group and the racial group represented in the picture, adapted to children and based on three factors (language, eating habits, and music). Results revealed an effect of age on racial categorization: the older the children, the more successful they are in this task. They showed a significant effect of the racial group represented in the photos on perceived cultural distance: members of minority groups (i.e., Black‐ and North‐Africans) were evaluated as more different compared to those of the majority group on each of the factors. Finally, we got an interaction between participants' in‐group and the racial group represented in the pictures, for the language factor: members of the majority group perceived as more different photographs representing minorities peers than those representing majority peers, while participants belonging to minority groups perceived no differences between photographs, according to the racial criteria.     

Personality and absenteeism: a meta‐analysis of integrity tests

Until recently, research focus has been on a variety of demographic, attitudinal, and organizational variables in predicting and explaining absenteeism. If personality traits predict absenteeism, then it may be possible to use measures of these traits to identify and select job applicants and thereby reduce absenteeism rates. In this research, our goal was to examine whether integrity tests could be used to predict absenteeism. Meta‐analysis was applied to studies of the validity of pre‐employment integrity tests for predicting voluntary absenteeism. Twenty‐eight studies based on a total sample of 13 972 were meta‐analysed. The estimated mean predictive validity of personality‐based integrity tests was 0.33. This operational validity generalized across various predictor scales, organizations, settings, and jobs (SD_ρ = 0.00). Overt integrity tests, however, showed much lower predictive validity for absenteeism and greater variability than personality‐based tests (ρ = 0.09; SD_ρ = 0.16). The results indicate that a personnel selection approach to reducing absenteeism in organizations may be a useful strategy, particularly if personality‐based integrity tests are utilized. Potential explanations for differences between these results and those found for Big Five measures of personality are offered. Future research investigating models of absenteeism should incorporate the personality constructs assessed by integrity tests. Copyright © 2003 John Wiley & Sons, Ltd.     

Applicant Reactions in Selection: Comprehensive meta‐analysis into reaction generalization versus situational specificity

This paper reports a comprehensive quantitative summary into applicant reactions to popular methods of employee selection. A detailed search of published and unpublished studies resulted in a final sample (k) of 38 independent samples covering 10 popular candidate assessment methods. Applicant reactions primary studies included samples from 17 countries internationally. Counter to previous suggestions for the situational specificity of applicant reactions, findings showed considerable similarity supporting the reaction generalizability hypothesis. Reaction favorability was structurally similar across countries and revealed a three‐tier clustering of overall favorability perceptions –most preferred (work samples, interviews), favorably evaluated (resumes, cognitive tests, references, biodata, personality inventories), and least preferred (honesty tests, personal contacts, graphology). Some differences in applicant reactions to dimension‐specific perceptions were found, however. Further analyses revealed strong positive correlations between favorability ratings and their validity and international usage. Implications for future research and ramifications for practice are considered in conclusion.     

Profit maximization versus disadvantageous inequality: the impact of self‐categorization

Choice behavior researchers (e.g., Bazerman, Loewenstein, & White, 1992 ) have found that individuals tend to choose a more lucrative but disadvantageously unequal payoff (e.g., self—$600/other—$800) over a less profitable but equal one (e.g., self—$500/other—$500); greater profit trumps interpersonal social comparison concerns in the choice setting. We suggest, however, that self‐categorization (e.g., Hogg, 2000 ) can shift interpersonal social comparison concerns to the intergroup level and make trading disadvantageous inequality for greater profit more difficult. Studies 1–3 show that profit maximization diminishes when recipients belong to different social categories (e.g., genders, universities). Study 2 further implicates self‐categorization, as self‐categorized individuals tend to forgo profit whether making a choice for themselves or another ingroup member. Study 3, moreover, reveals that social categorization alone is not sufficient to diminish profit maximization; individuals must self‐categorize and identify with their categorization.

Crossed categorization outside the lab: Findings from a factorial survey experiment

Crossed categorization studies investigate intergroup attitudes in situations when two categorization dimensions are simultaneously salient, often looking at artificial groups in laboratory settings. The current study tests (a) patterns of evaluation in crossed categorization scenarios when more than two real-life categorization dimensions are crossed, and (b) the moderating role of identity importance. We conduct a factorial survey experiment with a diverse sample (N = 524), crossing eight categorization dimensions. The results provide strong support for the additive pattern of crossed categorization, challenging the view that with an increased number of categories category-based information processing will not be used. Identity importance predicts the strength of intergroup bias only on the dimension of religion, which was the dominant dimension in this sample. The study contributes to multiple and crossed categorization literature by testing some of its key assumptions using a design that increases the ecological validity of the findings.     

Disconfirming intergroup evaluations: asymmetric effects for in-groups and out-groups

The authors examined whether a fundamental bias in the way people process information has implications for efforts to improve intergroup relations. The authors exposed participants to information about their own social category and a different social category that was either positive or negative in connotation. To examine what effect this information would have on participants' attitudes toward their own group and the other group, the authors measured both explicit and implicit evaluations before and after exposure. The findings suggest that, at a preconscious level, exposure to negative information affects participants' attitudes toward their own group, but that positive information has a negligible impact on attitudes toward other groups. The authors found an opposite pattern for explicit (conscious) evaluations. These asymmetries are consistent with cognitive and motivational theory on intergroup relations and may have important implications for efforts to reduce prejudice.
