Social identity as social glue: the origins of group loyalty

In 3 experiments, the authors investigated the role of social identity in fostering group loyalty, defined as staying when members can obtain better outcomes by leaving their group. In Experiment 1, high (vs. low) identifiers expressed a stronger desire to stay in the group in the presence of an attractive (vs. unattractive) exit option. Experiments 2 and 3 replicated this basic finding and tested several explanations. The results suggest that high identifiers' group loyalty is better explained by an extremely positive impression of their group membership (group perception) than by a justification of previous investments in the group (self-perception) or their adherence to a nonabandonment norm (norm perception). Hence, social identity seems to act as social glue. It provides stability in groups that would otherwise collapse.     

Football hooliganism: comparing self‐awareness and social identity theory explanations

The emergence of research interest in group violence in general and football hooliganism in particular has been explained by various models generally relying on situational or individual differences accounts. Yet, these two research traditions have largely evolved independently, showing little or no interaction. In the present study (N = 109), we integrate measures of these two approaches and the results reveal that social identity was more predictive of self‐reported physical aggression than of loss of private and public self‐awareness. Moreover, attitudes towards violence were the most marked predictor variables of both physical and verbal aggression. In the discussion, the moderator effect of social identity and attitudes about violence on physical aggression is elaborated upon. Copyright © 2007 John Wiley & Sons, Ltd.     

Ethnicity and gender in late childhood and early adolescence: group identity and awareness of bias

The current study examined awareness of gender and ethnic bias and gender and ethnic identity in 350 African American, White/European American, and Latino/Hispanic students (Mage = 11.21 years, SD = 1.59) from the 4th, 6th, and 8th grades of diverse middle and elementary schools. The study collected (a) qualitative data to best capture the types of bias that were most salient to children and (b) daily diaries and individual measures to examine the multiple components of children's gender and ethnic identities. Results revealed ethnic, gender, and grade-level differences in awareness of ethnic and gender bias. Overall, more children were aware of gender bias than ethnic bias. This effect was most pronounced among White/European American youths. Among those in 4th grade, African American and Latino youths were more likely to be aware of ethnic bias than were White/European American youths. Analyses also examined how awareness of bias was related to gender and ethnic identity. For example, children who had a salient and important gender identity, and a devalued ethnic identity, were less likely than other children to be aware of ethnic bias.     

Perceptions of group homogeneity as a function of social comparison: The mediating role of group identity

Recent research has shown that creating an intergroup context of comparison may influence the outgroup homogeneity effect or even turn it into an ingroup homogeneity effect. In the present study, the aim was to replicate these findings by using overall judgment of similarity instead of the more commonly used dimensional ratings. Further, and more importantly, it was argued that this effect could be explained by an increase in the salience of participants’ group identity. The results showed that context of comparison revealed an effect on both level of group identification and perceptions of relative ingroup and outgroup homogeneity. In line with predictions, participants’ level of group identification seemed to account for the effect of the comparison context on the homogeneity ratings.     

社会身份重要性和社会认同对群体参照效应的影响

研究选取四个参照条件（国家、民族、性别、职业）,探讨个体内部的社会身份重要性、以及个体对其不同社会身份的社会认同度对群体参照效应的影响。结果表明,在个体内部,社会身份重要性越重要,相应的群体参照效应也越大,而社会认同的高低对群体参照效应的大小没有显著影响。这表明在个体的自我内部,不同的社会身份是按照重要性来排列,越重要身份越靠近个体自我概念的核心,而且这种重要性也影响着集体自我相关信息的认知加工。

Stressing the group: social identity and the unfolding dynamics of responses to stress

Participants in the British Broadcasting Corporation (BBC) prison study were randomly assigned to high-status (guard) and low-status (prisoner) groups. Structural interventions increased the prisoners' sense of shared group identity and their willingness to challenge the power of the guards. Psychometric, physiological, behavioral, and observational data support the hypothesis that identity-based processes also affected participants' experience of stress. As prisoners' sense of shared identity increased, they provided each other with more social support and effectively resisted the adverse effects of situational stressors. As guards' sense of shared identity declined, they provided each other with less support and succumbed to stressors. Findings support an integrated social identity model of stress that addresses intragroup and intergroup dynamics of the stress process.     

The development of in-group favoritism: between social reality and group identity

This study examined how social reality restricts children's tendency for in-group favoritism in group evaluations. Children were faced with social reality considerations and with group identity concerns. Using short stories, in this experimental study, conducted among 3 age groups (6-, 8-, and 10-year-olds), the authors examined the trait attribution effects of reality constraints on eye-color differences and national group differences. The results show that the trait attributions of all age groups were restricted by the acceptance of socially defined reality. In addition, when the information about reality was not considered accurate, only the youngest children showed positive in-group favoritism. It is argued that these findings are useful in trying to reconcile some of the divergent and contrasting findings in the developmental literature on children's intergroup perceptions and evaluations.     

Diversity in the person,diversity in the group: Challenges of identity complexity for social perception and social interaction

Social psychological research is increasingly coming to grips with the complexity of social identity within the individual, both from the perspective of perceivers trying to form impressions and make judgments about multiply categorizable targets, as well as from the perspective of actors using their different self‐aspects as a framework for guiding their interactions with the social world. I review several contributions to the effort to better understand these issues and then explore some of their possible implications for understanding the nature and consequences of diversity within the group.

Developing the social identity theory of leadership: Leader agency in leader group prototypicality

The social identity theory of leadership is a unique perspective in leadership research in capturing how responses to leadership are informed by how the leader is perceived through the lens of the group identity shared by leaders and followers. I review the theory in broad strokes to make the case that a particularly valuable future development of the theory is to complement the theory's emphasis on group member (follower) perceptions of leader group prototypicality, the extent to which the leader is perceived to embody the group identity, with theory and evidence speaking to leader agency in influencing such perceptions.     

Individuality and social influence in groups: inductive and deductive routes to group identity

A distinction between forms of social identity formation in small interactive groups is investigated. In groups in which a common identity is available or given, norms for individual behavior may be deduced from group properties (deductive identity). In groups in which interpersonal relations are central, a group identity may also be induced from individual group members' contributions, making individuality and individual distinctiveness a defining feature of the group (inductive identity). Two studies examined the prediction that depersonalization produced by anonymity has opposite effects for groups in which social identity has been induced or deduced. Results confirmed the prediction that depersonalization increases social influence in groups whose identity was more deductive. In contrast, depersonalization decreases social influence in inductive identity groups. Implications for the role of social identity in small groups are discussed.

When the victim is one among others: Empathy,awareness of others and motivational ambivalence

Feeling empathy for one person in need while being aware of others may increase the motivational ambivalence between the motive of helping the one and the motive of helping the others, and such motivational ambivalence may reduce the helping directed to the person in need. To test these hypotheses we carried out three studies in which participants were faced with a real case of a child in need. In Study 1, empathy, awareness of others and motivational ambivalence were allowed to occur naturally and subsequently measured. In Study 2, empathy and awareness of others were experimentally manipulated, and motivational ambivalence measured. In Study 3, we tested how empathy and motivational ambivalence influenced an actual helping decision. Taken together, the results supported our two hypotheses. The present research offers insight into processes not previously considered in the research, but which may influence decisions about assistance to others in need.     

Beyond homeostasis: toward a concept of coherence

The concept of homeostasis has served as a major building block, if not the cornerstone, of family theory and family therapy. Designed to account for the perceived stability of systems (and symptoms), homeostasis is an epistemologically flawed concept that has repetitively been used in the service of dualistic, animistic, and vitalistic interpretations of systems. Accordingly, homeostasis has led to quirky clinical formulations and a great deal of fuzzy theorizing. This paper contends that the notion of homeostasis is fundamentally inconsistent with systemic epistemology and should be replaced with the more compatible concept of coherence. Whereas homeostasis is a heuristic concept that is not part of a more encompassing theory, the concept of coherence is inseparable from the epistemology in which it is embedded.     

Cross-cultural model testing: toward a solution of the etic-emic dilemma

A model for the prediction of behavior from attitudinal components, developed by Triandis, was tested with samples of U.S. and Mexican women, and with fertility relevant behaviors. The elements of the model are etic, but the operationalizations of the various variables were done emically. Results support the model in both cultures. While the predictive utility of the model is equivalent in two cultures, there are social class differences on which component of the model is most emphasized. The U.S. upper-middle-class sample and the Mexican upper-middle-class sample emphasized the person's attitude toward the act, while the Mexican lower SES (socio-economic status) sample emphasized the person's normative beliefs (moral obligations).     

The give-or-take-some dilemma: An empirical investigation of a hybrid social dilemma

We describe and empirically investigate a hybrid social dilemma that merges give-some and take-some dilemmas by allowing individuals to choose to either give or to take resources from a shared resource pool. Study 1 finds that (a) group size increases the inequality among group members and the likelihood of creating the public good, while reducing the amount of wasted resources; (b) larger bonuses increase provision rates; and (c) asymmetry in the wealth distribution of the group members induces higher levels of inequality of the final outcomes. Following the logic of appropriateness, players with high (low) endowments were more likely to give toward (take from) the shared resource. Study 2 finds that the tendency of the players with high (low) endowments to give (take) is amplified as the difference between endowment levels increased, and the players’ behavior is correlated with, and predictable from, independent judgments of what is perceived as appropriate.     

Attitudes toward Indigenous Australians: the role of empathy and guilt

Previous research in Perth, Western Australia, finds a disturbing amount of prejudice against Indigenous Australians. At the forefront of much prejudice research has been the distinction between old‐fashioned and modern prejudice. We constructed an Attitude Toward Indigenous Australians scale from items originating from qualitative data. We found that negative attitudes were predicted by collective guilt about past and present wrongs to Indigenous Australians (collective guilt directly linked to Indigenous issues, as well as collective guilt generally). Negative attitudes were also predicted by a lack of empathy for Indigenous Australians, and affective perspective taking generally. Socio‐demographics (e.g. a lack of education) predicted negative attitudes, which indicate the necessity of taking both social‐psychological and socio‐demographic factors into account when examining the nature of prejudice. A number of practical implications arise from these findings. Copyright © 2004 John Wiley & Sons, Ltd.
