Toward a histology of social behavior: Judgmental accuracy from thin slices of the behavioral stream

Publisher Summary A thin slice is defined as “a brief excerpt of expressive behavior sampled from the behavioral stream.” Thin slices can be sampled from any available channel of communication—including the face, the body, speech, the voice, transcripts, or combinations of the above. The expressive behavior sampled is diagnostic of many affective, personalities, and interpersonal conditions. This chapter focuses on thin slices and illustrates the efficiency of thin slices in providing information about social and interpersonal relations. It discusses the cognitive and affective mechanisms that influence the processing of information from thin slices of the behavioral stream. Further, the chapter discusses the theoretical and methodological boundaries of thin-slice judgments. The chapter concludes with two newspaper accounts that illustrate the importance of the accurate communication and perception of thin slices. The ultimate goal of perception and judgment of thin slices of the behavioral stream is to understand the ways in which individuals come to know and negotiate their social environment.

An FMRI investigation of the impact of interracial contact on executive function

We investigated whether individual differences in racial bias among white participants predict the recruitment, and potential depletion, of executive attentional resources during contact with black individuals. White individuals completed an unobtrusive measure of racial bias, then interacted with a black individual, and finally completed an ostensibly unrelated Stroop color-naming test. In a separate functional magnetic resonance imaging (fMRI) session, subjects were presented with unfamiliar black male faces, and the activity of brain regions thought to be critical to executive control was assessed. We found that racial bias predicted activity in right dorsolateral prefrontal cortex (DLPFC) in response to black faces. Furthermore, activity in this region predicted Stroop interference after an actual interracial interaction, and it statistically mediated the relation between racial bias and Stroop interference. These results are consistent with a resource depletion account of the temporary executive dysfunction seen in racially biased individuals after interracial contact.

Why Do Interracial Interactions Impair Executive Function? A Resource Depletion Account

Three studies investigated the veracity of a resource depletion account of the impairment of inhibitory task performance after interracial contact. White individuals engaged in either an interracial or same-race interaction, then completed an ostensibly unrelated Stroop color-naming test. In each study, the self-regulatory demands of the interaction were either increased (Study 1) or decreased (Studies 2 and 3). Results revealed that increasing the self-regulatory demands of an interracial interaction led to greater Stroop interference compared with control, whereas reducing self-regulatory demands led to less Stroop interference. Manipulating self-regulatory demands did not affect Stroop performance after same-race interactions. Taken together, the present studies point to resource depletion as the likely mechanism underlying the impairment of cognitive functioning after interracial dyadic interactions.

Stereotype performance boosts: The impact of self-relevance and the manner of stereotype activation.

The activation of positive stereotypes has been shown to produce academic performance boosts. Evidence regarding the role of self-relevance in producing such effects has been mixed. The authors propose that the subtlety of stereotype activation plays a key role in creating performance boosts among targets and nontargets of stereotypes. Study 1 found that subtle stereotype activation boosted performance in targets, but blatant activation did not. Study 2 was conducted on both targets and nontargets using different methods of stereotype activation. Again, targets showed performance boosts when stereotypes were subtly activated but not when they were blatantly activated. Nontargets, however, showed boosts in performance only when stereotypes were blatantly activated. The role of self-relevance in mediating sensitivity to stimuli is discussed.

Expecting To Be the Target of Prejudice: Implications for Interethnic Interactions

Two studies investigated the implications of ethnic minorities’ prejudice expectations for their affective and behavioral outcomes during interethnic interactions. In both studies, the more ethnic minorities expected Whites to be prejudiced, the more negative experiences they had during interethnic interactions. This finding held true for chronic prejudice expectations in a diary study of college roommates (Study 1) and for situationally induced prejudice expectations in a laboratory interaction (Study 2). In Study 2, the authors extended this work to examine the relationship between ethnic minorities’ prejudice expectancies and their White partners’ psychological experience during interethnic interactions. Consistent with predictions, the more ethnic minorities expected Whites to be prejudiced, the more their White partners had positive experiences during interethnic interactions. These divergent experiences of ethnic minorities and Whites have important implications for the psychological success of interactions between members of these groups.

Negotiating Interracial Interactions Costs, Consequences, and Possibilities

The United States is becoming increasingly diverse, yet interracial contact continues to be awkward, if not stressful, for many. Indeed, recent research suggests that individuals often exit interracial interactions feeling drained both cognitively and emotionally. This article reviews research examining how interracial encounters give rise to these outcomes, zeroing in on the mediating role of self-regulation and the moderating influence of prejudice concerns. Given that interracial contact may be the most promising avenue to prejudice reduction, it is important to examine factors that undermine positive interracial contact experiences, as well as those that facilitate them.

Predicting Behavior During Interracial Interactions: A Stress and Coping Approach

The social psychological literature maintains unequivocally that interracial contact is stressful. Yet research and theory have rarely considered how stress may shape behavior during interracial interactions. To address this empirical and theoretical gap, the authors propose a framework for understanding and predicting behavior during interracial interactions rooted in the stress and coping literature. Specifically, they propose that individuals often appraise interracial interactions as a threat, experience stress, and therefore cope—they antagonize, avoid, freeze, or engage. In other words, the behavioral dynamics of interracial interactions can be understood as initial stress reactions and subsequent coping responses. After articulating the framework and its predictions for behavior during interracial interactions, the authors examine its ability to organize the extant literature on behavioral dynamics during interracial compared with same-race contact. They conclude with a discussion of the implications of the stress and coping framework for improving research and fostering more positive interracial contact.

Middle Class and Marginal? Socioeconomic Status, Stigma, and Self-Regulation at an Elite University

In four studies, the authors investigated the proposal that in the context of an elite university, individuals from relatively lower socioeconomic status (SES) backgrounds possess a stigmatized identity and, as such, experience (a) concerns regarding their academic fit and (b) self-regulatory depletion as a result of managing these concerns. Study 1, a correlational study, revealed the predicted associations between SES, concerns about academic fit, and self-regulatory strength. Results from Studies 2 and 3 suggested that self-presentation involving the academic domain is depleting for lower (but not higher) SES students: After a self-presentation task about academic achievement, lower SES students consumed more candy (Study 2) and exhibited poorer Stroop performance (Study 3) relative to their higher SES peers; in contrast, the groups did not differ after discussing a nonacademic topic (Study 3). Study 4 revealed the potential for eliminating the SES group difference in depletion via a social comparison manipulation. Taken together, these studies support the hypothesis that managing concerns about marginality can have deleterious consequences for self-regulatory resources.

Effects of situational power on automatic racial prejudice

Abstract This study examined the influence of situational power on automatic racial prejudice. White females anticipated participating in either an interracial or same-race interaction in one of two roles: superior or subordinate. Their racial attitudes were measured via the Implicit Association Test ( Greenwald, McGhee, & Schwartz, 1998 ). Results revealed that both the racial composition of the anticipated dyad and participants’ situational roles influenced automatic racial attitudes. Specifically, whites assigned to the high-power role of a superior of a black individual revealed more racial bias than whites assigned to the lower-power role of a subordinate. By contrast, situational power had no influence on the automatic bias of whites anticipating same-race interactions. These results reveal the manner in which situational power hierarchies serve to reinforce existing social stratification. Implications for diversity efforts and attitude change are discussed.

The Negative Consequences of Threat: A Functional Magnetic Resonance Imaging Investigation of the Neural Mechanisms Underlying Women's Underperformance in Math

This study used functional magnetic resonance imaging to identify the neural structures associated with womens underperformance on math tasks. Although women in a control condition recruited neural networks that are associated with mathematical learning (i.e., angular gyrus, left parietal and prefrontal cortex), women who were reminded of gender stereotypes about math ability did not recruit these regions, and instead revealed heightened activation in a neural region associated with social and emotional processing (ventral anterior cingulate cortex).
