Cardiovascular correlates of emotional expression and suppression: Do content and gender context matter?

Three studies examined cardiovascular (CV) responses during emotional expression with empathically responsive strangers. Study 1 demonstrated that self-relevant emotional expression fostered CV reactivity consistent with challenge. Study 2 manipulated content of discussion by assigning participants to 1 of 4 conditions: emotional, nonemotional, emotional suppression, nonemotional suppression. In same-sex dyads, emotional suppression elicited CV challenge reactivity whereas emotional suppression evoked CV threat reactivity, both compared with appropriate control groups. In opposite-sex dyads, however, emotional expression engendered CV threat. Because same- and opposite-sex disclosures differed, Study 3 controlled the content of emotional expression while manipulating gender context. Results confirmed findings from the first 2 studies, indicating that both context and content of emotional expression influenced CV effects. Findings are discussed within a theoretical challenge and threat perspective. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Threatened by the unexpected: Physiological responses during social interactions with expectancy-violating partners.

Individuals who violate expectations increase uncertainty during social interactions. Three experiments explored whether expectancy-violating partners engender "threat" responses in perceivers. Participants interacted with confederates who violated or confirmed expectations while multiple measures were assessed, including cardiovascular reactivity, task performance, appraisals, and behavior. In Experiments 1 and 2, participants interacted with White or Latino confederates who described their family backgrounds as either high or low socioeconomic status. In Experiment 3, participants interacted with Asian or White confederates who spoke with expected accents or southern accents. Participants interacting with expectancy-violating partners (e.g., Asians with southern accents) exhibited cardiovascular responses consistent with threat, poorer task performance, and manifested negative and defeat-related behavior. Implications for decreasing prejudicial responses via uncertainty reduction are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of justice beliefs on cognitive appraisal of and subjective physiological, and behavioral responses to potential stress.

Investigated the moderating role of just world beliefs on stress and coping processes. Ss high and low in belief in a just world were asked to perform a potentially stressful laboratory task, which was repeated once. Cognitive appraisals and subjective, autonomic, and behavioral responses were recorded for each of the 2 tasks. The results supported a stress-moderating effect for just world beliefs. lndividuals high in just world beliefs had more benign cognitive appraisals of the stress tasks, rated the tasks as less stressful post hoc, had autonomic reactions consistent with challenge (vs threat), and outperformed Ss low in just world beliefs. Discussion centers on factors that moderate the experiences of challenge and threat in potentially stressful situations. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Using a preamble to increase presence in digital virtual environments

Immersion in a digital virtual environment (DVE) increases the likelihood that individuals will feel present in the DVE and hence respond as they would in a similar physically grounded environment. Previous research utilizing high-fidelity technology has demonstrated that by starting a virtual experience in a virtual replica of the immediate physical environment, presence is increased. The purpose of this study was to determine whether utilizing such a transitional environment to increase presence could be replicated on a significantly less immersive system—a 2D desktop monitor with mouse and keyboard for navigation. Participants began their DVE experience either in a “preamble” DVE made to look like the surrounding physical laboratory space, or in a novel DVE (i.e., a house). Then, they were given verbal instructions to leave their respective environments and told to go up a set of stairs to explore a museum. Afterward, they reported levels of immersion and presence in the latter DVE. Results demonstrated that entering a target DVE via a familiar “preamble” environment increased perceptions of reality judgment of the virtual experience, perceptions of possibility to act, and levels of presence. These results suggest that incorporating a familiar digital preamble environment as a prelude to the target DVE enables DVE designers and enthusiasts to increase presence without having to invest in more expensive hardware, but it could also augment existing immersive technology. Their efficacy may be because they offer a gradual transition into the virtual world, such that the familiarity eases users into the novel experience.     

Racism and racial categorization.

Social identity theory predicts that perceivers strongly identified with an in-group will maximize the distinction and maintain a clear boundary between their own and other groups by categorizing others' membership accurately. Two experiments tested the prediction that racially prejudiced individuals, who presumably identify highly with their racial in-group, are more motivated to make accurate racial categorizations than nonprejudiced individuals. Results indicated that prejudiced participants not only took longer to categorize race-ambiguous targets (Experiments 1 and 2), but also made more nonverbal vocalizations when presented with them (Experiment 1), suggesting response hesitation. The results support the hypothesis that, compared to nonprejudiced individuals, prejudiced individuals concern themselves with accurate identification of in-group and out-group members and use caution when making racial categorizations.

The Relationship Between Self-Esteem Level, Self-Esteem Stability, and Cardiovascular Reactions to Performance Feedback.

The authors examined the notion that individuals with unstable high self-esteem possess implicit self-doubt. They adopted the framework of the biopsychosocial model of challenge and threat and assessed spontaneous cardiovascular reactions in the face of success versus failure performance feedback. Study 1 revealed predicted interactions between feedback condition, self-esteem level, and self-esteem stability, such that participants with unstable high self-esteem exhibited relative threat (a negative reaction) in the failure condition, whereas those with stable high self-esteem exhibited relative challenge (a positive reaction). Study 2 replicated these results and provided additional evidence against plausible alternative explanations. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Perceiver threat in social interactions with stigmatized others.

The extent to which stigmatized interaction partners engender perceivers' threat reactions (i.e., stigma–threat hypothesis) was examined. Experiments 1 and 2 included the manipulation of stigma using facial birthmarks. Experiment 3 included manipulations of race and socioeconomic status. Threat responses were measured physiologically, behaviorally, and subjectively. Perceivers interacting with stigmatized partners exhibited cardiovascular reactivity consistent with threat and poorer performance compared with participants interacting with nonstigmatized partners, who exhibited challenge reactivity. In Experiment 3, intergroup contact moderated physiological reactivity such that participants who reported more contact with Black persons exhibited less physiological threat when interacting with them. These results support the stigma–threat hypothesis and suggest the utility of a biopsychosocial approach to the study of stigma and related constructs.

Effects of self-esteem and performance feedback on future affective preferences and cognitive expectations.

Tested the hypothesis that individuals, regardless of their chronic levels of self-esteem, affectively prefer success to failure but cognitively continue to expect success or failure in a manner consistent with their chronic levels of self-esteem. 64 high, moderate, and low self-esteem females (Texas Social Behavior Inventory) were given either success, failure, or no feedback regarding their performance on an "analogies test." Ss' preference for performance, perceived ability for performance, and predictions for actual performance on a future task were assessed. As predicted, Ss preferred future success to future failure regardless of chronic level of self-esteem. Ss with high or low chronic levels of self-esteem perceived ability for future performance and expected actual future performance in a manner consistent with their chronic levels of self-esteem rather than consistent with feedback on current performance.
