In 2 meta-analyses, we examined the relationship between perceived discrimination and psychological well-being and tested a number of moderators of that relationship. In Meta-Analysis 1 (328 independent effect sizes, N = 144,246), we examined correlational data measuring both perceived discrimination and psychological well-being (e.g., self-esteem, depression, anxiety, psychological distress, life satisfaction). Using a random-effects model, the mean weighted effect size was significantly negative, indicating harm (r = -.23). Effect sizes were larger for disadvantaged groups (r = -.24) compared to advantaged groups (r = -.10), larger for children compared to adults, larger for perceptions of personal discrimination compared to group discrimination, and weaker for racism and sexism compared to other stigmas. The negative relationship was significant across different operationalizations of well-being but was somewhat weaker for positive outcomes (e.g., self-esteem, positive affect) than for negative outcomes (e.g., depression, anxiety, negative affect). Importantly, the effect size was significantly negative even in longitudinal studies that controlled for prior levels of well-being (r = -.15). In Meta-Analysis 2 (54 independent effect sizes, N = 2,640), we examined experimental data from studies manipulating perceptions of discrimination and measuring well-being. We found that the effect of discrimination on well-being was significantly negative for studies that manipulated general perceptions of discrimination (d = -.25), but effects did not differ from 0 when attributions to discrimination for a specific negative event were compared to personal attributions (d = .06). Overall, results support the idea that the pervasiveness of perceived discrimination is fundamental to its harmful effects on psychological well-being.

In many Western countries, the proportion of the population that is White will drop below 50% within the next century. Two experiments examined how anticipation of these future ethnic demographics affects current intergroup processes. In Study 1, White Americans who viewed actual demographic projections for a time when Whites are no longer a numerical majority felt more angry toward and fearful of ethnic minorities than Whites who did not view future projections. Whites who viewed the future projections also felt more sympathy for their ingroup than Whites in the control condition. In Study 2, the authors replicated the effects for intergroup emotions with a sample of White Canadians. White Canadians who thought about a future in which Whites were a numerical minority appraised the ingroup as more threatened, which mediated the effect of condition on intergroup emotions. The authors discuss the implications of these findings for race relations in increasingly diverse societies.

Two well-established predictors of collective action are perceptions of group effi cacy and feelings of anger. The current research investigates the extent to which the relative impact of these variables differs when fear is or is not also included as a predictor of collective action. The results of two experiments indicate that when fear is not assessed, the importance of anger as a predictor of action is underestimated while the importance of group effi cacy is overestimated. The results further indicate that fear, in addition to affecting the impact of known causes of collective action (anger and group effi cacy), is a powerful inhibitor of collective action. The implications for current theoretical models of collective action instigators are discussed.For the Roman Emperor Caligula, the above quote was a favorite maxim. History suggests that Caligula was a tyrannical ruler who was hated by both the general population and the Roman Senate. Although Caligula was well aware of how he was perceived, he believed he could avoid being overthrown as long as people feared him more than they hated him. Caligula's quote nicely illustrates the potential connection between fear, anger, and collective action. Although common-sense explanations of collective action imply that fear can inhibit collective action, social psychologists have largely overlooked fear as an inhibitor of protest

It has become increasingly common for parents of children with autism to supplement behavior analytic interventions with therapies that have not yet been subjected to adequate scientific scrutiny. When caregivers elect to use unproven therapies despite advice to the contrary, practitioners should employ the methods of applied behavior analysis to experimentally evaluate the outcomes. Controlled evaluations of unproven therapies can be challenging, however, particularly when ongoing behavioral services are supplemented with biomedical interventions. This paper describes the methods and results of a behavior analytic evaluation of hyperbaric oxygen therapy, an unproven intervention that has been growing in popularity over the past several years. Three young children with autism participated. No benefits of the therapy were evident beyond those obtained through the behavioral intervention alone. Considerations for conducting this type of research are highlighted, along with suggestions for practitioners.

The current research investigated participants' reactions to positive and negative comments directed toward them as individuals or as members of a social group. Using both perspective-taking (Studies 1 and 2) and actual interaction methodologies (Study 3), three studies found that participants generally responded negatively to negative comments regardless of the level of identity to which the comment was directed. Positive comments were generally viewed positively, except when the comment was directed at the group and was stereotype relevant. When the latter was the case, participants reported increased anger and desires to attack (and avoid) the speaker. Furthermore, these negative feelings and action tendencies were partially mediated by an attribution to prejudice to the speaker.
