Dual identities in intergroup contact: Group status and size moderate the generalization of positive attitude change

To explore the effects of various categorization strategies on intergroup bias within and beyond a contact situation, two experiments were conducted involving groups of different size and/or status that worked together on a cooperative task. Three categorization strategies (decategorization, recategorization, and dual identity) were compared, and bias was measured through symbolic reward allocations to people who were and were not actually encountered. In Experiment 1 (N = 129), we varied group size (minority or majority) and found that it affected bias within the contact situation—minority groups were more biased than majority groups. All of the categorization strategies limited bias and they did so equally well. Outside the contact situation, however, only the recategorization and dual identity strategies limited bias. In Experiment 2 (N = 156), we varied both group status (low or high) and group size. Both of these variables affected bias within the contact situation—high status groups were more biased than low status groups, and minority groups were again more biased than majority groups. Once again, all three categorization strategies limited bias and they did so equally well. Outside the contact situation, however, an interaction among the independent variables was observed. For minority groups, only the dual identity strategy limited bias, but none of the categorization strategies limited bias for majority groups.     

Superordinate goals and intergroup behaviour: The effect of role ambiguity and status on intergroup attitudes and task performance

An experiment examined the effects of role ambiguity and relative group status in an intergroup situation where a superordinate goal was salient. One-hundred-and-fifty-six subjects in groups of three undertook a cooperative task under conditions where the groups' roles were clearly Different, Similar, or not allocated (Control). In addition, the groups' perceived competence at the task was either equally High, equally Low, or unequal. Financial rewards were contingent on successful completion of the joint task. Two contrasting hypotheses were derived from Social Identity Theory: one (H1) predicted most favourable intergroup attitudes in the Control condition where lack of any clear differentiation in group roles might facilitate a superordinate identifcation. In contrast, (H2) predicted least favourable attitudes in this condition on the grounds that groups lacked a distinctive identity. Support for the second hypothesis was found since friendliness towards the outgroup decreased with increasing role ambiguity. The status variable also had consistent effects. As predicted, mutual evaluations tended to reflect the consensually agreed status differences: least bias being shown towards high status outgroups, most by high status ingroups. Task performance was also affected by role ambiguity. Judges' ratings of the group products were found to be more favourable as role ambiguity increased, in contrast to the friendliness data. The implications of these findings for Social Identity Theory, the Contact Hypothesis, and theories of group performance are discussed.     

Colonic sensitivity in irritable bowel syndrome and normal subjects according to their hemispheric preference and cognitive style

According to our earlier results, non-painful, weak afferent visceral signals may exert a steady influence on brain processes, including cognitive functions. In the present series colonic impulses of irritable bowel syndrome (IBS) subjects served as a model of chronic impact from the gut. Hemispheric preference, as well as cognitive style of information processing served as indicators of covert changes in brain functions. In twentyone IBS patients and in ten control subjects of both sexes, the thresholds of minimal colonic distension sensitivity has been measured following the determination of hemispheric preference and of advantage in verbal or spatial information processing of the subjects. In IBS patients distension thresholds proved to be higher in verbals than in spatials, whereas in healthy controls the relationship of colonic thresholds and verbal versus, spatial advantage was reversed. Among the normal controls with left hemisphere preference a significantly higher distension threshold has been observed than in those with right hemisphere preference, whereas in the IBS group such threshold-differences were not observable.     

Shame expressions reduce the recipient’s insult from outgroup reparations

Despite a growing literature on the consequences of group-based guilt and shame, little work has examined how expressions of self-conscious emotions are received by targets of collective wrongdoing. Two experiments tested the hypothesis that when an outgroup member offers apologies accompanied by reparations, the recipients are likely to take insult unless the outgroup member expresses the self-abasing emotion of shame rather than guilt. Experiment 1 showed that when reparations were offered, participants were less insulted by shame than guilt expressed by an outgroup member, rather than an ingroup member. Experiment 2 improved Experiment 1 by manipulating the culprit’s action (reparation vs. withdrawal), and this experiment replicated Experiment 1’s interaction on a measure of insult, but only when reparations were offered. These interactions on insult were not explained by the emotion’s perceived intensity or surprisingness. Our results indicate a possible functional aspect of expressions of shame in an intergroup context. Self-abasement, as opposed to a mere admission of culpability and regret, can reduce the insult taken from an outgroup’s reparations.     

Evidence for attenuated affective processing in obesity

Attenuated affective processing is hypothesized to play a role in the development and maintenance of obesity. Using an affective priming task measuring automatic affective processing of verbal stimuli, a group of 30 obese participants in a weight-loss program at the Psychosomatic University Clinic Bonn (M age = 48.3, SD = 10.7) was compared with a group of 25 participants of normal weight (M age = 43.6, SD = 12.5). A smaller affective priming effect was observed for participants with obesity, indicating less pronounced reactions to valenced adjectives. The generally reduced affective processing in obese participants was discussed as a possible factor in the etiology of obesity. Individuals who generally show less pronounced affective reactions to a given stimulus may also react with less negative affect when confronted with weight gain or less positive affect when weight is lost. Consequently, they could be expected to be less motivated to stop overeating or to engage in dieting and will have a higher risk of becoming or staying obese.     

Dealing with the past and facing the future: mediators of the effects of collective guilt and shame in Bosnia and Herzegovina

Two studies are reported which examined potential mediators of the effects of collective guilt and shame on reparation attitudes. Samples of young Bosnian Serbs (Ns = 173, 247) were asked to report their feelings of guilt and shame for what their group had done during the 1992–1995 war in Bosnia Herzegovina. They also reported their attitudes towards making reparation to Bosnian Muslims. Both collective guilt and shame positively predicted reparation attitudes, but these associations were differently mediated. The effects of guilt were mediated by empathy for the outgroup, while the effects of shame were mediated by self‐pity and empathy. The theoretical and applied implications of these findings are discussed. Copyright © 2007 John Wiley & Sons, Ltd.     

Evaluations of pleasurable experiences: The peak-end rule

Prior research suggests that the addition of mild pain to an aversive event may lead people to prefer and directly choose more pain over less pain (Kahneman, Fredrickson, Schreiber, & Redelmeier, 1993). Kahneman et al. suggest that pain ratings are based on a combination of peak pain and final pain. Similarly, people rate a happy life that ends suddenly as being better than one with additional years of mild happiness (Diener, Wirtz, & Oishi, 2001), even though the former objectively consists of less pleasure than the latter. Applying these concepts to material goods, we investigated the impact of positivity and timing on the retrospective evaluations of material goods. We found strong evidence that the peak-end rule applies to both material goods and pain.     

Racial phenotypicality bias in educational expectations for both male and female teenagers from different socioeconomic backgrounds

In three experiments (N = 56, 99, and 225), we showed that racial phenotypicality bias characterizes educational expectations for Chilean mestizo students: participants displayed more positive educational expectations for light complexioned than for dark complexioned high school students. In Study 1, with male high school target students, the relation between racial phenotypic appearance and educational expectations was mediated by differences in perceived competence. Study 2 suggests that the gender of the target student did not influence the occurrence of racial phenotypicality bias. Study 3 showed that racial phenotypicality bias occurs in both university students and high school teachers' judgements. Although socioeconomic background of the target student partially explained the effects of racial phenotypic appearance (especially in teachers), the latter exerted an additional and independent influence on educational expectations. These results underline the fact that effects of racial phenotypicality bias should not be overlooked in the educational domain. As mediational analyses suggested, these effects only partly occur because of stereotypical associations between racial phenotypic appearance and socioeconomic background, but also because of stereotypical associations between racial phenotypic appearance and attributed competence.
