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)     

Effects of acceptance-oriented versus evaluative emotional processing on heart rate recovery and habituation.

The effects of emotional processing on stress response trajectories may depend on the nature of processing, as evaluative rumination about emotions can prolong distress. In contrast, observing negative emotions in an accepting manner may promote efficient recovery from stressful situations. The present study examined the effect of acceptance-oriented versus evaluative emotional processing on cardiovascular habituation and recovery. Across two experimental sessions, 81 participants were randomly assigned to write about an ongoing stressful experience while either (1) evaluating the appropriateness of their emotional response (EVAL), (2) attending to their emotions in an accepting way (ACC), or (3) describing the objective details of the experience (CTL). Heart rate was assessed continuously throughout baseline, writing, and recovery. Results suggest that writing about emotions in an evaluative way leads to less efficient heart rate habituation and recovery than processing emotions in an accepting manner. These findings highlight a potential mechanism of mindfulness- and acceptance-based interventions' effects on health outcomes and further suggest that habitually evaluating the appropriateness of one's emotional responses rather than accepting them as they unfold may have consequences for cardiovascular health.

Job demands, decisional control, and cardiovascular responses.

The demand-control model for coronary heart disease was tested using ambulatory blood pressure monitoring. Male patrol officers (N = 118) wore ambulatory blood pressure monitors during 1 of their day shifts with readings taken every 30 min. Following each reading, officers completed a questionnaire using a handheld computer. Significant interactions were obtained between job demands and decisional control for heart rate and pressure rate product such that both variables were highest under conditions of high demand and low control. Main effects were obtained for control such that diastolic blood pressure and mean arterial pressure were significantly higher under conditions of low control. These results support the demand-control model and emphasize the importance of psychological control in cardiovascular responses. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Socially mediated reduction in emotional responses of young rhesus monkeys.

"Two studies investigated the effect of various social stimuli upon emotional responsiveness of 12 young rhesus monkeys raised in the laboratory in the visual presence of other young monkeys… . results suggest that the nature of Ss' previous social experience was an important determinant of stimulus effectiveness in reducing emotional distress. The capacity of a social stimulus to mitigate emotional disturbance did not appear to be dependent upon nor derived from feeding or other nurturant experience."

The effects of perceived discrimination on ambulatory blood pressure and affective responses to interpersonal stress modeled over 24 hours.

Objective: This research examined the impact of perceived discrimination on ambulatory blood pressure (ABP) and daily level affect during social interaction. Design: For 24 hrs, adult Black and White participants wore an ABP monitor and completed palm pilot diary entries about their social interactions. Main Outcome Measures: Mean level and time-trend trajectories of blood pressure and heart rate were examined as well as mean level measures of positive and negative affect after stressful and nonstressful social interactions. Results: Analyses showed that, after controlling for important covariates, perceived discrimination predicted the slopes of both wake and nocturnal ABP responses, with those who reported more discrimination having steeper daytime trajectories for systolic and diastolic blood pressure and less nighttime dipping in heart rate over time as compared to those who had reported relatively infrequent discrimination. High levels of perceived discrimination were also related to positive and negative affective responses after stressful encounters. Conclusions: These results suggest that, regardless of race, perceived discrimination is related to cardiovascular and affective responses that may increase vulnerability to pathogenic processes.

Differential subjective and psychophysiological responses to socially and nonsocially generated emotional stimuli.

Sociality may determine the subjective experience and physiological response to emotional stimuli. Film segments induced socially and nonsocially generated emotions. Comedy (social positive), bereavement (social negative), pizza scenes (nonsocial positive), and wounded bodies (nonsocial negative) elicited four distinct emotional patterns. Per subjective report, joy, sadness, appetite, and disgust were elicited by the targeted stimulus condition. The social/nonsocial dimension influenced which emotional valence(s) elicited a skin conductance response, a finding that could not be explained by differences in subjective arousal. Heart rate deceleration was more responsive to nonsocially generated emotions. Taken together, these findings suggest that sociality affects the physiological profile of responses to emotional valence. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Convergent and divergent responses to emotional displays of ingroup and outgroup.

In the present research, we test the assumption that emotional mimicry and contagion are moderated by group membership. We report two studies using facial electromyography (EMG; Study 1), Facial Action Coding System (FACS; Study 2), and self-reported emotions (Study 2) as dependent measures. As predicted, both studies show that ingroup anger and fear displays were mimicked to a greater extent than outgroup displays of these emotions. The self-report data in Study 2 further showed specific divergent reactions to outgroup anger and fear displays. Outgroup anger evoked fear, and outgroup fear evoked aversion. Interestingly, mimicry increased liking for ingroup models but not for outgroup models. The findings are discussed in terms of the social functions of emotions in group contexts.

The social consequences of expressive suppression.

At times, people keep their emotions from showing during social interactions. The authors' analysis suggests that such expressive suppression should disrupt communication and increase stress levels. To test this hypothesis, the authors conducted 2 studies in which unacquainted pairs of women discussed an upsetting topic. In Study 1, one member of each pair was randomly assigned to (a) suppress her emotional behavior, (b) respond naturally, or (c) cognitively reappraise in a way that reduced emotional responding. Suppression alone disrupted communication and magnified blood pressure responses in the suppressors' partners. In Study 2, suppression had a negative impact on the regulators' emotional experience and increased blood pressure in both regulators and their partners. Suppression also reduced rapport and inhibited relationship formation. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

How attributional ambiguity shapes physiological and emotional responses to social rejection and acceptance.

The authors examined White and Black participants' emotional, physiological, and behavioral responses to same-race or different-race evaluators, following rejecting social feedback or accepting social feedback. As expected, in ingroup interactions, the authors observed deleterious responses to social rejection and benign responses to social acceptance. Deleterious responses included cardiovascular (CV) reactivity consistent with threat states and poorer performance, whereas benign responses included CV reactivity consistent with challenge states and better performance. In intergroup interactions, however, a more complex pattern of responses emerged. Social rejection from different-race evaluators engendered more anger and activational responses, regardless of participants' race. In contrast, social acceptance produced an asymmetrical race pattern--White participants responded more positively than did Black participants. The latter appeared vigilant and exhibited threat responses. Discussion centers on implications for attributional ambiguity theory and potential pathways from discrimination to health outcomes.

Magnitude and duration of cardiovascular response to anger in Vietnam veterans with and without posttraumatic stress disorder.

This study investigated the cardiovascular responses to a relived anger task in 118 male Vietnam combat veterans (62 with posttraumatic stress disorder [PTSD] and 56 without PTSD). Participants completed standardized diagnostic measures, hostility measures, and a laboratory session in which they relived a self-chosen anger memory while heart rate (HR), systolic blood pressure, and diastolic blood pressure (DBP) were measured continuously using an Ohmeda Finapres monitor. Compared with veterans without PTSD, PTSD veterans took less time to feel anger, had greater mean HR and DBP response during relived anger, and reported greater anger and anxiety during the task. There was a significant relationship between covert hostility and anger response during and after the anger task only in participants with PTSD.

Affective and cardiovascular effects of experimentally-induced social status.

Objective: Observational research suggests subordinate social status is associated with negative mental and physical health outcomes. However, observational studies have limitations, including confounding of social status with other factors, limited ability to infer causality, and difficulty of obtaining detailed affective and physiologic data. This study used experimental methods to test the hypothesis that subordinate social status per se causes psychological distress and cardiovascular arousal. Design: Forty-four women were randomly assigned to an induced subordinate or dominant status condition. Social status was manipulated using a procedure derived from status construction theory. Main Outcome Measures: Affective responses were assessed via self-report. Cardiovascular responses were assessed by measures of systolic and diastolic blood pressures obtained with an automated blood pressure machine. Results: Participants in the subordinate condition perceived themselves as lower in status; the reverse was true for dominant condition participants. Compared with induced dominant status, induced subordinate status produced increased negative affect and systolic blood pressure over the course of the study. Conclusion: Findings suggest social status can be experimentally manipulated and short-term induction of subordinate status can have adverse effects on affect and stress-related physiological systems. Results have implications for understanding how socioeconomic status "gets under the skin" to influence health. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Comparison of emotional responses in monkeys with rhinal cortex or amygdala lesions.

Four emotionally arousing stimuli were used to probe the behavior of monkeys with bilateral ablations of the entorhinal and perirhinal cortex. The monkeys' behavioral changes were then contrasted with those observed earlier (M. Meunier, J. Bachevalier, E. A. Murray, L. Málková, & M. Mishkin, 1999) in monkeys with either neurotoxic or aspiration lesions of the neighboring amygdala. Rhinal cortex ablations yielded several subtle behavioral changes but none of them resembled any of the disorders typically seen after amygdalectomies. The changes produced by rhinal damage took mainly the form of heightened defensiveness and attenuated submission and approach responses, that is, just the opposite of some of the most distinctive symptoms following amygdala damage. These findings raise the possibility that the rhinal cortex and amygdala have distinct, interactive functions in normal behavioral adaptation to affective stimuli.

Effect of brief puppet therapy upon the emotional responses of children undergoing cardiac catheterization.

40 children between ages 3 and 11, admitted to a children's hospital for cardiac catheterization (CC), served as Ss for a study of the effect of this therapy upon the emotional responses of patients hospitalized for this diagnostic procedure. 20 of the Ss were assigned randomly to an experimental group which received puppet therapy before and after CC; 20 were placed in a control group which was not given therapy but otherwise was treated similarly to the experimental group. Children who received therapy were less disturbed during CC (p     

The impact of changes in spatial distance on emotional responses.

Drawing on motivational approaches to emotion, the authors propose that the perceived change in spatial distance to pictures that arouse negative emotions exerts an influence on the significance of these pictures. Two experiments induced the illusion that affective pictures approach toward the observer, recede from the observer, or remain static. To determine the motivational significance of the pictures, emotional valence and arousal ratings as well as startle responses were assessed. Approaching unpleasant pictures were found to exert an influence on both the valence and the arousal elicited by the pictures. Furthermore, movement of pleasant or neutral pictures did not influence startle responses, while the second experiment showed that approaching unpleasant pictures elicited enhanced startle responses compared to receding unpleasant pictures. These findings support the view that a change of spatial distance influences motivational significance and thereby shapes emotional responses.

Subjective responses to emotional stimuli during labeling, reappraisal, and distraction.

Although multiple neuroimaging studies suggest that affect labeling (i.e., putting feelings into words) can dampen affect-related responses in the amygdala, the consequences of affect labeling have not been examined in other channels of emotional responding. We conducted four studies examining the effect of affect labeling on self-reported emotional experience. In study one, self-reported distress was lower during affect labeling, compared to passive watching, of negative emotional pictures. Studies two and three added reappraisal and distraction conditions, respectively. Affect labeling showed similar effects on self-reported distress as both of these intentional emotion regulation strategies. In each of the first three studies, however, participant predictions about the effects of affect labeling suggest that unlike reappraisal and distraction, people do not believe affect labeling to be an effective emotion regulation strategy. Even after having the experience of affect labels leading to lower distress, participants still predicted that affect labeling would increase distress in the future. Thus, affect labeling is best described as an incidental emotion regulation process. Finally, study four employed positive emotional pictures and here, affect labeling was associated with diminished self-reported pleasure, relative to passive watching. This suggests that affect labeling tends to dampen affective responses in general, rather than specifically alleviating negative affect.

The effects of fear arousal and suppression of fear upon social perception.

A research was designed to study the effects of fear arousal and suppression of fear upon social perception. "It was hypothesized that individuals subjected to a fear-producing situation would tend to project their feelings upon some social objects, and further, instructions to inhibit emotional reactions would increase the amount of projection." Sixty male volunteers from introductory psychology classes were randomly assigned to one of three groups: Control, Fear-Expression and Fear-Suppression. "The data indicate that the arousal of fear results in a tendency to project fear onto a stimulus object in the environment. The results are also consistent with the hypothesis that suppression facilitates the tendency to project although, in this latter instance, one is less confident in rejecting the null hypothesis. Several alternative explanations of the effects of the suppression variable were considered and the role of cognitive variables in the projection process were discussed."

White students reflecting on whiteness: Understanding emotional responses.

In the present investigation, we explored potential predictors of White students' general emotional responses after they reflected on their Whiteness in a semistructured interview (n = 88) or written reflection (n = 187). Specifically, we examined how color-blindness (i.e., awareness of White privilege) and racial affect (i.e., White empathy, White guilt, and White fear), assessed before the interview or written reflection, may predict positive and negative emotional responses, assessed immediately following the interview or written reflection. Furthermore, we considered whether affective costs of racism to Whites moderated the association between racial color-blindness and general positive and negative emotional responses of White students. Findings indicated that affective costs of racism moderated associations between racial color-blindness and general emotional responses. Specifically, White fear moderated associations for the written reflection group whereas White empathy moderated an association in the interview. White guilt did not moderate, but instead directly predicted a negative emotional response in the written reflection group. Findings suggest that the interaction between racial color-blindness and racial affect is important when predicting students' emotional responses to reflecting on their Whiteness. Implications for educators and administrators are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Increased Vulnerability to Stress Following Opiate Exposures: Behavioral and Autonomic Correlates.

The authors used rats to study the impact of a history of opiate exposures on behavioral and autonomic responses to restraint stress. Brief restraint (30 min) provoked tachycardia and a pressor response, anxiety (as indexed by social interaction), grooming, and reduced exploration. The pressor response was reduced at 1 day, but not 7 days, after last opiate exposure; tachycardia was unaffected (Experiment 1). Stress-induced anxiety was potentiated 1 and 7 days after last opiate exposure (Experiment 2), and this potentiation was a function of dose (Experiment 3) and duration (Experiment 4) of opiate exposure. The results show that a history of opiate exposures alters vulnerability to stress and has implications for understanding coping, anxiety, and emotionality in former opiate users.

Longitudinal effects of emotional labour on emotional exhaustion and dedication of teachers.

A great number of teachers find teaching fulfilling and are dedicated to it, but others feel emotionally exhausted, indicating that the interaction with pupils can be emotionally demanding. Emotional labor was shown to play an important role for the health of teachers. In a full two-wave longitudinal study over the period of 1 year, the effect of emotional labor on emotional exhaustion and dedication of 102 teachers was investigated. Teachers who were able to influence their emotions to feel the emotion appropriate in a situation (so called deep acting) felt significantly less emotionally exhausted after 1 year. From this result, deep acting can, thus, be characterized as health-beneficial. Once teachers felt emotionally exhausted, they used more surface acting. More dedicated teachers, on the contrary, did neither engage more in deep acting nor in surface acting at Time 2. This indicates that those teachers who are dedicated to teaching seem less likely to act. To prevent emotional exhaustion of teachers, the development of interventions to promote health-beneficial emotional labor is necessary. This can be achieved by fostering deep acting, which reduces emotional exhaustion over longer periods of time. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
