Bridging faultlines by valuing diversity: diversity beliefs, information elaboration, and performance in diverse work groups

Although there are numerous potential benefits to diversity in work groups, converging dimensions of diversity often prevent groups from exploiting this potential. In a study of heterogeneous decision-making groups, the authors examined whether the disruptive effects of diversity faultlines can be overcome by convincing groups of the value of diversity. Groups were persuaded either of the value of diversity or the value of similarity for group performance, and they were provided with either homogeneous or heterogeneous information. As expected, informationally diverse groups performed better when they held pro-diversity rather than pro-similarity beliefs, whereas the performance of informationally homogeneous groups was unaffected by diversity beliefs. This effect was mediated by group-level information elaboration. Implications for diversity management in organizations are discussed.     

Expressing anger in conflict: when it helps and when it hurts

Do expressions of anger in conflict elicit competition or cooperation? To reconcile inconsistent results obtained in previous research, the authors developed and tested a dual-process model that proposes that power and the appropriateness of the expressions of anger jointly determine whether an individual facing an angry antagonist competes by demanding value or cooperates by conceding value. In a scenario study and a computer-mediated negotiation simulation, (a) participants with lower power claimed less value from an angry adversary than from a nonemotional one, regardless of the appropriateness of the expressions of anger, and (b) participants with higher power demanded more value when the adversary's expressions of anger were inappropriate than when they were appropriate or when the adversary was nonemotional. The theoretical and practical implications of the model and findings are discussed.     

People as intuitive prosecutors: The impact of social-control goals on attributions of responsibility

Three experiments explored determinants of punitive character attributions to norm violators. Experiment 1 showed that ideological conservatism and manipulated threat to society increased anger and attributional punitiveness when there was ambiguity about culpability. Experiment 2 showed that informing observers that norm violations were widespread and rarely punished increased attributional punitiveness by activating anger-charged retributive goals. Experiment 3 showed that liberals and conservatives alike felt justified in assigning greater blame to high-status perpetrators who commit acts of negligence with more severe consequences but that only conservatives felt justified in doing so for low-status perpetrators. Overall, the results reinforce the hypothesis that societal threat activates a prosecutorial mindset identifiable by a correlated cluster of attributions, emotions, punishment goals and punitiveness.     

The effects of analytical and experiential rumination on autobiographical memory specificity in individuals with a history of major depression

This study examined the relationship between analytical rumination and autobiographical memory specificity in participants with a history of depression. Participants completed the autobiographical memory test twice, once before and once after an 8 min manipulation designed to increase either an abstract/analytical or concrete/experiential mode of information processing. Results indicated a significant three-way time (pre, post)×manipulation (analytical, experiential)×depressive rumination (high, low) interaction. This interaction was the result of a significant decline in memory specificity from pre- to post-manipulation in individuals reporting high levels of rumination about symptoms when depressed who were allocated to the analytical condition. The findings of this study extend previous work, suggesting that low memory specificity in formerly depressed patients may be a function of state levels of analytical self-focus, with this cognitive style being more easily reinstated in the recovery phase in those who report a greater trait tendency to ruminate about symptoms when low in mood.     

Neural coding of reward magnitude in the orbitofrontal cortex of the rat during a five-odor olfactory discrimination task

The orbitofrontal cortex (OBFc) has been suggested to code the motivational value of environmental stimuli and to use this information for the flexible guidance of goal-directed behavior. To examine whether information regarding reward prediction is quantitatively represented in the rat OBFc, neural activity was recorded during an olfactory discrimination “go”/“no-go” task in which five different odor stimuli were predictive for various amounts of reward or an aversive reinforcer. Neural correlates related to both actual and expected reward magnitude were observed. Responses related to reward expectation occurred during the execution of the behavioral response toward the reward site and within a waiting period prior to reinforcement delivery. About one-half of these neurons demonstrated differential firing toward the different reward sizes. These data provide new and strong evidence that reward expectancy, regardless of reward magnitude, is coded by neurons of the rat OBFc, and are indicative for representation of quantitative information concerning expected reward. Moreover, neural correlates of reward expectancy appear to be distributed across both motor and nonmotor phases of the task.     

T1 difficulty and the attentional blink: expectancy versus backward masking

According to bottleneck models of the attentional blink (AB), first-target (T1) processing difficulty should be related to AB magnitude. Tests of this prediction that have varied T1 difficulty in the context of a standard AB paradigm, however, have yielded mixed results. The present work examines two factors that may mediate the relationship between T1 difficulty and the AB: observer expectancy and backward masking of T1. In two experiments, omission of the backward mask consistently yielded the predicted relationship between T1 difficulty and the AB. In contrast, observer expectancy influenced target identification accuracy but did not mediate the relationship between T1 difficulty and the AB.     

The more (complex), the better? The influence of epistemic motivation on integrative bargaining in complex negotiation

Negotiating about a larger number of issues is often argued to enhance the potential for integrative bargaining. However, the enhanced complexity may also make negotiators more susceptible to bias, making it less likely for them to reach win–win agreements. We argue that epistemic motivation, the motivation to hold accurate perceptions of the world, provides a key to solve this paradox. In a negotiation experiment we manipulated complexity by having participants negotiate about 6 or 18 issues and we manipulated epistemic motivation by making participants process‐accountable or not. Under low complexity, there was no effect of epistemic motivation on created value. Under high complexity, however, negotiators with high epistemic motivation created more value than negotiators with low epistemic motivation. Thus, negotiating about larger numbers of issues was only beneficial for negotiators if they were motivated to think deeply and thoroughly. Copyright © 2009 John Wiley & Sons, Ltd.     

Self-Objectification, Self-Esteem, and Gender: Testing a Moderated Mediation Model

The purpose of the present research was to test the mediating roles of body shame and appearance anxiety in the relation between self-surveillance and self-esteem; and to investigate whether gender (male, female) and stereotypical gender roles (masculinity, femininity) moderated the proposed mediation model. Canadian undergraduate university men and women (n?=?198) completed measures of self-surveillance, gender, gender roles, body shame, appearance anxiety, and self-esteem. Regression analyses demonstrated that greater self-surveillance predicted lower self-esteem, and this relation was fully mediated by body shame and appearance anxiety. With the exception of masculinity interacting with self-surveillance to predict body shame and appearance anxiety, neither gender nor stereotypical gender roles moderated the proposed paths. Implications are discussed.
