ABSTRACT: This paper introduces a single-item social identification measure (SISI) that involves rating one's agreement with the statement 'I identify with my group (or category)' followed by a 7-point scale. Three studies provide evidence of the validity (convergent, divergent, and test-retest) of SISI with a broad range of social groups. Overall, the estimated reliability of SISI is good. To address the broader issue of single-item measure reliability, a meta-analysis of 16 widely used single-item measures is reported. The reliability of single-item scales ranges from low to reasonably high. Compared with this field, reliability of the SISI is high. In general, short measures struggle to achieve acceptable reliability because the constructs they assess are broad and heterogeneous. In the case of social identification, however, the construct appears to be sufficiently homogeneous to be adequately operationalized with a single item.

ABSTRACT: This article examines whether and how moral convictions predict collective action to achieve social change. Because moral convictions - defined as strong and absolute stances on moral issues - tolerate no exceptions, any violation motivates individuals to actively change that situation. We propose that moral convictions have a special relationship with politicized identities and collective action because of the potentially strong normative fit between moral convictions and the action-oriented content of politicized identities. This effectively integrates moral conviction with the Social Identity Model of Collective Action (Van Zomeren, Postmes, & Spears, 2008), which predicts that, on the basis of a relevant social identity, group-based anger and efficacy predict collective action. Results from two studies indeed showed that moral convictions predicted collective action intentions (Study 1-2) and collective action (Study 2) through politicized identification, group-based anger, and group efficacy. We discuss theoretical and practical implications of our integrative model.

ABSTRACT: In 2 field studies (Ns = 71 and 113), we tested the prediction that in-group identification would mediate the acquisition of group norms by new group members. Study 1 demonstrated that participants surveyed after a team-development program reported greater awareness of in-group norms of teamwork and cooperation, compared to those surveyed at the start. Moreover, there was evidence that this effect was mediated by increased in-group identification. Study 2 replicated this finding, and showed that the effects were specific to the norm of teamwork. Acquisition of alternative norms of individualism and competitiveness did not increase after participation in the program, and did not correlate with identification. Practical implications and future work are discussed.

ABSTRACT: This article examines inductive processes of social identity formation, the bottom-up processes by which individual group members influence a social identity, integrating it with work on entitativity. Three studies tested the prediction that feelings of individual distinctiveness mediate the relation between inductive social identity formation and entitativity and that entitativity in turn predicts identification. The studies provided consistent support for this theoretical model over alternative models, using a range of different social groups and methods. Study 1 found support for the model in self-selected small groups. Study 2 supported it with a much broader set of groups that were not self-selected. Finally, Study 3 varied levels of inductive social identity formation systematically by varying group size and provided direct support for the hypothesized causal relations.

ABSTRACT: Two studies explore how salience of the human category influences responses to intergroup harm and how different images of humanity modify these effects. In Study 1, British participants (n = 86) contemplated acts of terrorism against their group. When the human category (versus intergroup distinctions) was salient and when the prevailing image of humanity was malevolent (versus benevolent), participants were not only more understanding of terrorism, blamed this less on religious group memberships, but also more strongly endorsed the use of extreme force by countries to defend their boarders, preserve the peace and prevent future attacks. In Study 2, British participants (n = 83) contemplated the torture of Iraqi prisoners by British soldiers. When the human category was salient and the prevailing image of humanity was malevolent, participants experienced less guilt and justified torture more. We conclude that the effects of human category salience on interpretations of intergroup harm depend on what it means to be human. When human nature is perceived negatively, thinking in terms of the human category can normalise intergroup harm regardless of whether the outgroup or the ingroup is the perpetrator. Implications for re-categorisation approaches to conflict reduction are discussed. Copyright © 2011 John Wiley & Sons, Ltd.

ABSTRACT: The present research examined how intra- and inter-team discussions prior to negotiations affect negotiation processes and outcomes. A Pilot Study showed that intra-team discussions motivate negotiators to understand the underlying interests more deeply (i.e. epistemic motivation), whereas inter-team discussions foster a greater concern for the counterpart (i.e. prosocial motivation). Experiment 1 showed that teams, independent of their power, achieved greater economic and social outcomes when they engaged in intra- and inter-team discussions instead of just one discussion format or none at all. In a multiparty setting, Experiment 2 showed why: intra-team discussions resulted in greater economic outcomes because they increased negotiators' understanding of the underlying interests, whereas inter-team discussions improved social outcomes because they encouraged cooperative behaviour. Experiment 3 examined the order in which both discussion formats are administered and found that an intra-team discussion, followed by an inter-team discussion resulted in better economic and social outcomes than a reverse order because it established greater alignment between negotiating teams.

ABSTRACT: Research has shown that group discussion can increase intergroup prejudice and discrimination. However, we know little about the process by which discussion has this effect. Therefore, four studies were conducted in a real-world context to investigate this process. Results suggest that discussing a negative societal stereotype (relative to individual rumination in Studies 1 and 3 and alternative discussions in Studies 2 and 3) increases intentions to engage in discrimination against the out-group target of the stereotype. This is mediated by the formation of an in-group norm which supports discrimination (Study 1) and the extent to which the discussion validates the stereotype (Study 2). A fourth study manipulated the extent to which consensus on the negative stereotype was reached through discussion. When the discussion ended in consensus, participants have greater intention to undertake collective action against the stereotyped out-group, mediated by a congruent in-group norm. These results provide evidence that the process by which discussion increases intergroup discrimination is via the formation of discriminatory local group norms.

ABSTRACT: Self-categorization theory suggests that inter-group comparisons inform individual behaviour by affecting perceived in-group stereotypes that are internalized by group members. The present paper provides evidence for this chain of effects in the domain of environmental behaviour. In two studies, inter-group comparative context was manipulated. Study 1 found that the perceived in-group stereotype, self-stereotype (as represented by the reported value centrality), and behavioural intentions shifted away from a comparison out-group (irrespective of whether this was an upward or downward comparison). Study 1 also revealed that the effect of comparative context on individual environmental intentions was mediated by the perceived in-group stereotype and by changes in personal values. Study 2 extrapolated the observed effect on actual behavioural choices. The findings demonstrate the utility of a self-categorization approach to individual behaviour change.

ABSTRACT: Research has elaborated considerably on the dimensions of out-group stereotype content and on the origins and functions of different content combinations. Less attention has been given to the origins and functions of in-group stereotype content. We argue that in-group stereotypes are likely to serve different social identity functions, and thus attract different content, dependent on individual differences in in-group identification and on the temporal perspective of the perceiver. Two studies (Ns = 43 and 93) found that women's in-group stereotype content varied as a function of gender group identification and temporal perspective. When the past was primed, highly identified women generated stereotypes that emphasized the warmth (but not competence) of their group. When the future was primed, highly identified women generated stereotypes that emphasized the competence (as well as warmth) of their group. These results are discussed in terms of the use of stereotypes for social creativity versus social change.

ABSTRACT: In two studies, we demonstrate that small group discussions change the extent to which an activated stereotype affects performance in a relevant domain. In Study 1, female participants were asked why men are (or are not) better than them at maths. They generated their answers individually or through group discussion, and their subsequent maths performance was highest when they collectively challenged the stereotype and lowest when they collectively affirmed the stereotype. When participants affirmed the stereotype through discussion, they used more theories which supported the validity of the stereotype, compared to the individual thought condition; and consensus mediated the effect of group discussion on performance (relative to individual rumination). In Study 2, male and female participants affirmed or challenged the stereotype in same-gender discussion groups. After affirming the stereotype, women's performance decreased relative to their baseline scores and men's performance was 'lifted'. In contrast, when they challenged the stereotype, there was no difference between the performance of men and women on the maths test. This pattern of effects was mediated by confidence in mathematical ability. The findings support the idea that topical small group discussions can, in the short term, differentially alter the impact that stereotypes have on performance.

ABSTRACT: Research into the relationship between stigmatization and well-being suggests that identification with a stigmatized group can buffer individuals from the adverse effects of stigma. In part, this is because social identification is hypothesized to provide a basis for social support which increases resistance to stigma and rejection of negative in-group stereotypes. The present research tests this model among individuals with mental health problems. As hypothesized, group identification predicted increased social support, stereotype rejection, and stigma resistance. These self-protective mechanisms were in turn found to predict higher levels of self-esteem. However, the general effect of these associations was to suppress a negative relationship between social identification and self-esteem. This confirms that the positive impact of identification lies in its capacity to provide access to stress-buffering mechanisms but also indicates that the impact of identification with a severely stigmatized group is not necessarily positive. Implications for theory and practice are discussed.

ABSTRACT: Previous theory and research suggests that perceiving shared humanity with others should be a positive force for intergroup relations. The present research considers the alternative possibility, that notions of shared humanity might protect people from feelings of guilt over ingroup perpetrated harm by obscuring the ingroup's unique role in these events. Consistent with this idea, Study 1 (N = 58) found that perceiving shared humanity with a harmed outgroup was associated with less guilt and stronger expectations of forgiveness among members of the perpetrator group. Study 2 (N = 52) demonstrated that these effects only occurred when the moral integrity of the ingroup was open to question. When ingroup morality was instead secure, defensive use of humanity was not apparent. Together, these studies suggest that perceiving harmful ingroup actions as ‘only human’ can sometimes be a moral defence that absolves group members of feelings of responsibility for wrongdoing.

ABSTRACT: The present studies investigated why video racing games increase players' risk-taking inclinations. Four studies reveal that playing video racing games increases risk taking in a subsequent simulated road traffic situation, as well as risk-promoting cognitions and emotions, blood pressure, sensation seeking, and attitudes toward reckless driving. Study 1 ruled out the role of experimental demand in creating such effects. Studies 2 and 3 showed that the effect of playing video racing games on risk taking was partially mediated by changes in self-perceptions as a reckless driver. These effects were evident only when the individual played racing games that reward traffic violations rather than racing games that do not reward traffic violations (Study 3) and when the individual was an active player of such games rather than a passive observer (Study 4). In sum, the results underline the potential negative impact of racing games on traffic safety.

ABSTRACT: The authors examine how beliefs about the stability of the social hierarchy moderate the link between sexism and essentialist beliefs about gender and how the expression of essentialist beliefs might reciprocally affect the social structure. Studies 1 (N = 240) and 2 (N = 143) presented gender-based inequality as stable, changing, or changed. In both studies, sexism was positively associated with essentialism only among men and only when inequality was presented as changing. Study 3 (N = 552) explored the possible consequences of expressing essentialist theories for social change. Exposure to essentialist theories increased both men's and women's acceptance of inequality. Exposure further increased men's support for discriminatory practices and boosted their self-esteem. These patterns demonstrate that although essentialism is linked to prejudice, this link is itself not essential. Rather, essentialism may be invoked strategically to protect higher status when this is threatened by change and may be successful in so doing.

ABSTRACT: The authors propose that the salience of a distant-future time perspective, compared to a near-future time perspective, should increase attitude-behaviour and attitude-intention consistency for future-oriented behaviours. To test this prediction, time perspective was experimentally manipulated in three studies. Across studies, participants in the distant-future time perspective condition demonstrated a strong positive relationship between attitudes towards future-oriented behaviours (saving and environmental protection) and corresponding intentions, as well as between attitudes and behaviour. In the near-future time perspective condition, the relationship between attitudes and intentions and attitudes and behaviour was significantly weaker than in the distant-future time perspective condition. The theoretical implications of these results and suggestions for future research are discussed.

ABSTRACT: There is considerable interest in how essentialist beliefs support prejudice and discrimination against minorities. Less attention has been given to essentialism within minority groups. The authors argue that minorities might use essentialism to counter the denial of their identity by the majority (e.g., marginalization) but that essentialism might be less appealing when minority identity is recognized but devalued (e.g., discrimination). In Study 1, gay, lesbian, and bisexual participants contemplated treatment that either devalued or denied their identity. Minority identification was related to stronger endorsement of beliefs about the immutability of sexuality in the context of identity denial but not in the context of identity devaluation. Study 2 replicated this pattern and showed that endorsement of immutability beliefs was mediated through the perceived possibility for social change and was in turn related to feelings of self-efficacy. The results are discussed in relation to current perspectives on essentialism.

ABSTRACT: This paper introduces the concept of self-defining groups to explain how personal and social aspects of identity relate to each other among members of an extreme right-wing political party. Two studies were conducted. Study 1 examined how affiliation with a social group that has clear-cut, rigid norms and values affects the personal and social self-concept. Participants were members of a (self-defining) Turkish nationalist organisation (N=66) and a control group of Turkish university students (N=58). Paradoxically, high levels of national identification were associated with stronger personal identity. Study 2 used the same participant population (N=177) and manipulated self-focused attention by means of a mirror. Self-aware members reported the highest levels of identification with the nationalist organisation. Results suggest that members of this groups show no signs of 'vanishing individuality': although boundaries between personal and social identities are blurred, extremist group members retain a distinct and strengthened sense of personal identity. This raises some interesting questions for the concept of personal identity and how it can be informed by the content of one's social identity.

ABSTRACT: Two longitudinal studies considered the role of social identity factors in predicting well-being after students' transition to university. The transition (assessed before starting university and after 2 months at university) had a detrimental effect on well-being, but identification as a university student improved well-being. Both studies showed that the social context in which the change occurred either facilitated or hindered university identification. Specifically, perceived compatibility between old and new identities and having multiple group memberships (which were each influenced by social class background, Study 2) both increased likelihood of identification with the new group. These predictive relationships remained statistically reliable when controlling for other factors relevant to the transition. The results suggest that life transitions are difficult partly because they entail changes in group membership. Both studies also demonstrate that identification with a new group can help buffer individuals from the negative well-being consequences of change.

ABSTRACT: Research suggests there is more inter-group discrimination when rewards rather than punishments are distributed between groups (the positive-negative asymmetry effect). This study investigated whether intra-group interaction and the obstruction of in-group advancement moderate this finding. Participants were twice asked to divide monetary resources—individually (pre-consensus) and in interactive groups (consensus). Results confirmed that there was more discrimination when rewards were allocated. Although this replicates the PNAE overall, there were two moderators. First, there was no asymmetry when the out-group obstructed in-group advancement: obstruction was sufficient to legitimise punishment. Second, after group interaction the PNAE reversed so that there was more discrimination when punishments were administered. The severity of discrimination was contingent upon group norms that endorsed inter-group hostility. It is argued that norms changed as a function of group interaction, and so did patterns of discrimination. The results suggest that the intra-and inter-group context combined to cause in-group favouritism to slide towards inter-group hostility. Copyright © 2007 John Wiley & Sons, Ltd.

ABSTRACT: An integrative social identity model of collective action (SIMCA) is developed that incorporates 3 socio-psychological perspectives on collective action. Three meta-analyses synthesized a total of 182 effects of perceived injustice, efficacy, and identity on collective action (corresponding to these socio-psychological perspectives). Results showed that, in isolation, all 3 predictors had medium-sized (and causal) effects. Moreover, results showed the importance of social identity in predicting collective action by supporting SIMCA's key predictions that (a) affective injustice and politicized identity produced stronger effects than those of non-affective injustice and non-politicized identity; (b) identity predicted collective action against both incidental and structural disadvantages, whereas injustice and efficacy predicted collective action against incidental disadvantages better than against structural disadvantages; (c) all 3 predictors had unique medium-sized effects on collective action when controlling for between-predictor covariance; and (d) identity bridged the injustice and efficacy explanations of collective action. Results also showed more support for SIMCA than for alternative models reflecting previous attempts at theoretical integration. The authors discuss key implications for theory, practice, future research, and further integration of social and psychological perspectives on collective action.
