Mind over matter: reappraising arousal improves cardiovascular and cognitive responses to stress.

Researchers have theorized that changing the way we think about our bodily responses can improve our physiological and cognitive reactions to stressful events. However, the underlying processes through which mental states improve downstream outcomes are not well understood. To this end, we examined whether reappraising stress-induced arousal could improve cardiovascular outcomes and decrease attentional bias for emotionally negative information. Participants were randomly assigned to either a reappraisal condition in which they were instructed to think about their physiological arousal during a stressful task as functional and adaptive, or to 1 of 2 control conditions: attention reorientation and no instructions. Relative to controls, participants instructed to reappraise their arousal exhibited more adaptive cardiovascular stress responses-increased cardiac efficiency and lower vascular resistance-and decreased attentional bias. Thus, reappraising arousal shows physiological and cognitive benefits. Implications for health and potential clinical applications are discussed.

Mere effort and stereotype threat performance effects.

Although the fact that stereotype threat impacts performance is well established, the underlying process(es) is(are) not clear. Recently, T. Schmader and M. Johns (2003) argued for a working memory interference account, which proposes that performance suffers because cognitive resources are expended on processing information associated with negative stereotypes. The antisaccade task provides a vehicle to test this account because optimal performance requires working memory resources to inhibit the tendency to look at an irrelevant, peripheral cue (the prepotent response) and to generate volitional saccades to the target. If stereotype threat occupies working memory resources, then the ability to inhibit the prepotent response and to launch volitional saccades will be impaired, and performance will suffer. In contrast, S. Harkinss (2006) mere effort account argues that stereotype threat participants are motivated to perform well, which potentiates the prepotent response, but also leads to efforts to counter this tendency if participants recognize that the response is incorrect, know the correct response, and have the opportunity to make it. Results from 4 experiments support the mere effort but not the working memory interference account.

Improving Acute Stress Responses The Power of Reappraisal

Contrary to lay beliefs, physiological changes that co-occur with stress are not necessarily bad. Much can be done during stressful experiences to promote adaptive responses. In this article, we review recent research on one method for improving acute stress responses: reappraising arousal. A growing body of research suggests that cognitive appraisals are powerful tools that help shift negative stress states to more positive ones. Arousal reappraisal instructs individuals to think of stress arousal as a tool that helps maximize performance. By reframing the meaning of the physiological signals that accompany stress, arousal reappraisal breaks the link between negative affective experiences and malignant physiological responses. We demonstrate how this approach can benefit physiological reactivity, attention, and performance and explore its potential applications.

Need Threat Can Motivate Performance After Ostracism

Ostracism threatens fundamental needs of belonging, self-esteem, control, and meaningful existence, which should motivate participants to respond to this threat. However, research has yet to examine the role of need threat in producing motivation after ostracism. In the current work, participants completed a “cognitive ability” (antisaccade) task following Cyberball-induced ostracism or inclusion. In two experiments, it was found that when ostracized, participants do not see antisaccade performance as a means of responding to the concerns produced by need threat; they respond only to the social threat, leading to worse performance than included participants (Experiments 1 and 2). However, when participants see an avenue of response (the Cyberball players can compare antisaccade performances), ostracized participants outperform included participants (Experiment 2). Moreover, this effect was mediated by the need for belonging, suggesting that ostracized participants were motivated to elevate their inclusionary status by demonstrating their worth on the cognitive ability task.

Experiencing Discrimination Increases Risk Taking

Prior research has revealed racial disparities in health outcomes and health-compromising behaviors, such as smoking and drug abuse. It has been suggested that discrimination contributes to such disparities, but the mechanisms through which this might occur are not well understood. In the research reported here, we examined whether the experience of discrimination affects acute physiological stress responses and increases risk-taking behavior. Black and White participants each received rejecting feedback from partners who were either of their own race (in-group rejection) or of a different race (out-group rejection, which could be interpreted as discrimination). Physiological (cardiovascular and neuroendocrine) changes, cognition (memory and attentional bias), affect, and risk-taking behavior were assessed. Significant Participant Race × Partner Race interactions were observed. Cross-race rejection, compared with same-race rejection, was associated with lower levels of cortisol, increased cardiac output, decreased vascular resistance, greater anger, increased attentional bias, and more risk-taking behavior. These data suggest that perceived discrimination is associated with distinct profiles of physiological reactivity, affect, cognitive processing, and risk taking, implicating direct and indirect pathways to health disparities.

How Developmental Psychopathology Theory and Research Can Inform the Research Domain Criteria (RDoC) Project

The recently proposed Research Domain Criteria (RDoC) project has the potential to stimulate new research and overcome many of the limitations of the Diagnostic and Statistical Manual of Mental Disorders taxonomy. In the present article we focus, in three main sections, on how theory and research from developmental psychopathology can inform RDoC. First, we discuss the ontology of mental illness and the potential advantages of the RDoC approach to understanding the nature of mental illness. Second, we note potential issues to consider when implementing the RDoC framework, including (a) integrating developmental processes, (b) classifying mental illness within a dimensional approach, and (c) avoiding problems associated with biological reductionism. Third, we describe how a developmental psychopathology perspective may inform each of these potential issues within RDoC. Finally, we highlight the study of emotion and the centrality of affective processes within the RDoC framework. Specifically, we describe how constructionist models of emotion are consistent with developmental psychopathology and how this perspective on emotion can help to guide RDoC research.

The Effect of Stereotype Threat on the Solving of Quantitative GRE Problems: A Mere Effort Interpretation

The mere effort account argues that stereotype threat motivates participants to want to perform well, which potentiates prepotent responses. If the prepotent response is correct, performance is facilitated. If incorrect and participants do not know, or lack the knowledge or time required for correction, performance is debilitated. The Graduate Record Examinations (GRE) quantitative test is made up of two problem types: (a) solve problems, which require the solution of an equation, and (b) comparison problems, which require the use of logic and estimation. Previous research shows that the prepotent tendency is to attempt to solve the equations. Consistent with mere effort predictions, Experiment 1 demonstrates that threatened participants perform better than controls on solve problems (prepotent response correct) but worse than controls on comparison problems (prepotent response incorrect). Experiment 2 shows that a simple instruction as to the correct solution approach eliminates the performance deficit on comparison problems.

Rethinking butterflies: the affective, physiological, and performance effects of reappraising arousal during social evaluation.

This study examined the effects of reappraising stress arousal on affective displays, physiological responses, and social performance during an evaluative situation. Participants were sampled from across the social anxiety spectrum and instructed to reappraise arousal as beneficial or received no instructions. Independent raters coded affective displays, nonverbal signaling, and speech performance. Saliva samples collected at baseline and after evaluation were assayed for salivary alpha-amylase (sAA), a protein that indexes sympathetic activation. Arousal reappraisal participants exhibited less shame and anxiety, less avoidant nonverbal signaling, and performed marginally better than no instruction controls. Reappraisal participants also exhibited increased levels of sAA and increased appraisals of coping resources compared with controls. Furthermore, stress appraisals mediated relationships between reappraisal and affective displays. This research indicates that reframing stress arousal can improve behavioral displays of affect during evaluative situations via altering cognitive appraisals.

Changing the conceptualization of stress in social anxiety disorder: Affective and physiological consequences

Social anxiety disorder (SAD) is a pervasive problem associated with debilitating impairments in social settings. This research explored the affective and physiological reactions to social evaluation and examined the efficacy of an arousal reappraisal intervention in altering cardiovascular reactivity and affective responses. Across two studies, socially anxious participants exhibited a disjunction between subjective ratings and physiological responses. Whereas anxious individuals reported more anxiety and negative affect during a stressful public speaking task relative to nonanxious controls, no differences emerged in physiological reactivity as a function of anxiety. In the second experiment socially anxious and nonanxious participants instructed to reframe stress arousal as a positive coping tool exhibited reduced attentional bias and improvements in physiological functioning: decreased vasoconstriction and increased cardiac efficiency. This research suggests that outcomes in SAD may be improved by reappraising stress arousal.

Testing the Mere Effort Account of the Evaluation-Performance Relationship

Research traditions in psychology in which the evaluation-performance relationship was examined do not show agreement on the mediating process, nor is there any compelling evidence that favors one account over the others. On the basis of a molecular analysis of performance on the Remote Associates Test (RAT), Harkins (2006) argued that the potential for evaluation motivates participants to perform well, which potentiates prepotent responses. If the prepotent response is correct, performance is facilitated. If the prepotent response is incorrect, and participants do not know, or if they lack the knowledge or time required for correction, performance is debilitated. The present research pits this mere effort account against 4 other potential explanations (withdrawal of effort, processing interference, focus of attention, and drive) on 3 tasks that were specifically selected for this purpose (anagram solution, the Stroop Color-Word task, and the antisaccade task). In each case, the results are consistent with the mere effort account.
