Replicating and extending Sengupta et al. (2023): Contact predicts no within-person longitudinal outgroup-bias change.

Intergroup contact has long been touted as a premier means to reduce prejudice and forge positive bonds with outgroups. Given its origins in psychological research, it is perhaps of little surprise that contact is expected to induce change within people over time. Yet using random-intercepts crossed-lagged modeling that parses within-person from between-person effects, Sengupta et al.

Reductions in perceived COVID-19 threat amid UK's mass public vaccination programme coincide with reductions in outgroup avoidance (but not prejudice).

It has long been proposed that perceptions of threat contribute to greater outgroup negativity. Much of the existing evidence on the threat-prejudice association in the real world, however, is cross-sectional in nature. Such designs do not adequately capture individual-level changes in constructs, and how changes in constructs relate to changes in other theoretically relevant constructs.

Intergroup contact, social dominance, and environmental concern: A test of the cognitive-liberalization hypothesis.

Intergroup contact is among the most effective ways to improve intergroup attitudes. Although it is now beyond any doubt that contact can reduce prejudice, in this article we provide evidence that its benefits can extend beyond intergroup relations-a process referred to as cognitive liberalization (Hodson, Crisp, Meleady, & Earle, 2018). We focus specifically on the impact of intergroup contact on environmentally relevant attitudes and behavior.

Exposure to intergroup conspiracy theories promotes prejudice which spreads across groups.

This research experimentally examined the effects of exposure to intergroup conspiracy theories on prejudice and discrimination. Study 1 (N = 166) demonstrated that exposure to conspiracy theories concerning immigrants to Britain from the European Union (vs. anti-conspiracy material or a control) exacerbated prejudice towards this group.

Intergroup Contact as an Agent of Cognitive Liberalization.

Intergroup contact is widely recognized as one of the most validated methods of improving attitudes toward out-groups. Yet what is intergroup contact "good for" beyond this function? To answer this question we take a panoramic view of the literature, beginning with the recognition that contact is multifaceted in both form (e.g.

Surveillance or Self-Surveillance? Behavioral Cues Can Increase the Rate of Drivers' Pro-Environmental Behavior at a Long Wait Stop.

By leaving their engines idling for long periods, drivers contribute unnecessarily to air pollution, waste fuel, and produce noise and fumes that harm the environment. Railway level crossings are sites where many cars idle, many times a day. In this research, testing two psychological theories of influence, we examine the potential to encourage drivers to switch off their ignition while waiting at rail crossings.

Examining the role of positive and negative intergroup contact and anti-immigrant prejudice in Brexit.

This study examined the interplay of anti-immigrant prejudice and intergroup contact experience on voting intentions within Britain's 2016 referendum on its membership in the European Union. In the days before the referendum, we asked more than 400 British people how they planned to vote. We measured a number of demographic factors expected to predict voting intentions as well as individuals' prejudice towards and intergroup contact experience (positive and negative) with EU immigrants.

Humanizing Outgroups Through Multiple Categorization: The Roles of Individuation and Threat.

In three studies, we examined the impact of multiple categorization on intergroup dehumanization. Study 1 showed that perceiving members of a rival university along multiple versus simple categorical dimensions enhanced the tendency to attribute human traits to this group. Study 2 showed that multiple versus simple categorization of immigrants increased the attribution of uniquely human emotions to them.

Systematic revisions to inherent notions may shape improvements in cognitive infrastructure.

The proposed inherence heuristic centers on perceivers' failure to systematically consider external, historical factors when explaining observed patterns. We stress that this does not preclude the potential of subsequently encountered information to challenge intuitions. Drawing on models of diversity-defined social cognition, we discuss how an updating mechanism may reciprocally shape the cognitive infrastructure that underlies reliance on heuristic systems.

Drinking in social groups. Does 'groupdrink' provide safety in numbers when deciding about risk?

Aims: To investigate the impact of alcohol consumption on risk decisions taken both individually and while part of a four- to six-person ad-hoc group.

Design: A 2 (alcohol: consuming versus not consuming alcohol) × 2 (decision: individual, group) mixed-model design; decision was a repeated measure. The dependent variable was risk preference, measured using choice dilemmas.

Simulating social dilemmas: promoting cooperative behavior through imagined group discussion.

A robust finding in social dilemmas research is that individual group members are more likely to act cooperatively if they are given the chance to discuss the dilemma with one another. The authors investigated whether imagining a group discussion may represent an effective means of increasing cooperative behavior in the absence of the opportunity for direct negotiation among decision makers. Five experiments, utilizing a range of task variants, tested this hypothesis.

On the evolutionary origins of revenge and forgiveness: a converging systems hypothesis.

McCullough et al. argue that humans possess evolved computational systems for implementing retaliatory behavior that both deters aggression and promotes subsequent reconciliation. However, they do not apply this analysis to the sphere of intergroup relations.

The group discussion effect: integrative processes and suggestions for implementation.

One of the most consistent findings in experimental social dilemmas research is the positive effect group discussion has on cooperative behavior. At a time when cooperation and consensus is critical to tackle global problems, ranging from debt to deforestation, understanding the dynamics of group discussion is a pressing need. Unfortunately, research investigating the underlying processes and implementation of the effect has been inconclusive.

Adapting to a multicultural future.

Humans have an evolved propensity to think categorically about social groups. This propensity is manifest in cognitive processes that have broad implications for public and political endorsement of multicultural policy. Drawing on these principles, we postulate a cognitive-evolutionary account of human adaptation to social diversity.
