Psychophysiological responses to anger provocation among Asian Indian and white men

Vigilance and Protection: How Asian and Pacific Islander, Black, Latina, and Middle Eastern Women Cope with Racism

BACKGROUND

Research is needed to fully investigate the differential mechanisms racial and ethnic groups use to deal with ongoing intersectional racism in women's lives. The aim of this paper was to understand how Asian American and Pacific Islander, Black, Latina, and Middle Eastern women experience racism-from personal perceptions and interactions to coping mechanisms and methods of protection.

METHODS

A purposive sample of 52 participants participated in 11 online racially/ethnically homogeneous focus groups conducted throughout the USA. A team consensus approach was utilized with codebook development and thematic analysis.

RESULTS

The findings relate to personal perceptions and interactions related to race and ethnicity, methods of protection against racism, vigilant behavior based on safety concerns, and unity across people of color. A few unique concerns by group included experiences of racism including physical violence among Asian American Pacific Islander groups, police brutality among Black groups, immigration discrimination in Latina groups, and religious discrimination in Middle Eastern groups. Changes in behavior for safety and protection include altering methods of transportation, teaching their children safety measures, and defending their immigration status. They shared strategies to help racial and ethnic minorities against racism including mental health resources and greater political representation. All racial and ethnic groups discussed the need for unity, solidarity, and allyship across various communities of color but for it to be authentic and long-lasting.

CONCLUSION

Greater understanding of the types of racism specific groups experience can inform policies and cultural change to reduce those factors.

Childhood adversity and physical health among Asian Indian emerging adults in the United States: Exploring disease-specific vulnerabilities and the role of anger

Objective: The link between adverse childhood experiences (ACEs) and negative health outcomes is well established among middle-aged adults and within the general population; however, ACEs' impact on physical health among emerging adults and specific ethnic minority groups, such as distinct Asian American subgroups, remains understudied and poorly understood. The aim of this study was to examine the relationships between ACEs, anger expression, stress, and physical health in a sample of Asian Indian (AI) emerging adults (18-29 years) living in the United States. Method: Participants (N = 132; Mage = 23.52; 13.6% first generation; 86.4% born in United States) completed an electronic questionnaire measuring variables of ACEs, anger expression, recent stress, health history, self-rated health, and recent physical illness symptoms. Chi-square, regression, and mediation analyses were conducted to examine associations among variables. Results: ACEs significantly predicted greater anger expression, perceived stress, number of chronic health conditions, and recent physical illness symptoms. Ninety-four percent of participants with ≥ 3 ACEs endorsed at least 1 previously diagnosed medical condition, and these participants exhibited remarkably high odds of diabetes and high blood pressure. Mediation analyses indicated anger expression significantly mediated ACEs' impact on recent stress and physical illness symptoms. Conclusions: Findings evidence that ACE-related physical health consequences are, in fact, already detectable by emerging adulthood among AI Americans. The distinct ACEs patterns and pronounced ACE-related health consequences found in this population warrant further study. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Convergence in feeling, divergence in physiology: How culture influences the consequences of disgust suppression and amplification among European Americans and Asian Americans

Much empirical work documents the downsides of suppressing emotions. Emerging research points to the need for a more sophisticated and culturally informed approach to understanding the consequences of emotion regulation. To that end, we employed behavioral, self-report, and psychophysiological measures to examine the consequences of two types of emotion regulation (suppression and amplification) in a sample of 28 Asian Americans and 31 European Americans. Participants were shown a neutral film and then a series of disgust-eliciting films during which they were asked to regulate their response by suppressing or amplifying their emotional behavior (counterbalanced). Despite self-reporting equal levels of disgust, European Americans showed greater skin conductance reactivity than Asian Americans in both regulation conditions, but not in response to a neutral film. These findings extend work on divergence in the consequences of emotion regulation across different cultural groups, which could help identify optimal emotion regulation strategies for health and well-being.

The Relationship between Expressive/Suppressive Hostility Behavior and Cardiac Autonomic Activations in Patients with Coronary Artery Disease

BACKGROUND

Hostility is an important psychosocial risk factor in coronary artery disease (CAD). Expressive and suppressive hostility behaviors are related to cardiovascular response in healthy adults. However, the relationships of these behavioral dimensions to cardiac autonomic activations in CAD remain unclear.

METHOD

This study involved 76 patients with CAD to whom a hostility inventory was administered, who were instructed to recall a neutral event and an anger-related event. Heart rate and blood pressure were obtained for each patient as the indices of cardiovascular response; heart rate variability was transformed from electrocardiograph and as the indices of cardiac autonomic activation.

RESULTS

The results showed that CAD patients with expressive hostility behavior experienced higher cardiovascular autonomic activations during the neutral and anger recall tasks, and lower parasympathetic activations during the recovery after an anger episode. On the other hand, CAD patients with suppressive hostility behavior experienced both sympathetic and parasympathetic activations during the baseline and recovery stages, as well as simultaneously activated higher parasympathetic response.

CONCLUSIONS

The results of this study suggested that it is appropriate to extend the cardiac autonomic activation model for expressive and suppressive hostility behaviors in patients with CAD.

KEY WORDS

Anger and globalization among young people in India

This article addresses the challenges faced by youth in developing countries. Using India as an example of a fast-globalizing country, this article highlights the experience and challenges faced by adolescents and emerging adults as they search for their interpersonal and professional identities. The difficulties of defining identity in the context of rapid globalization where people are exposed to diverse cultural forces that may conflict with each other are particularly salient when dealing with anger. Anger frequently results from thwarted wants and needs. In globalizing developing economies, young people often face inequitable access and opportunities that may be cause for distress-anger and depression. However, the skills to deal with anger are frequently culturally determined and may not be effective in situations where multiple cultural rules are operational. For example, India being a collectivist culture traditionally encourages the suppression of anger. However, situations and rules of conduct in a global economic order require the assertive expression of anger and the confrontation of conflict. Research that is methodologically and culturally appropriate is needed in exploring these issues and ameliorating distress associated with inequity, conflicts, and challenges.

Cardiovascular responses to stress in Singapore and India

BACKGROUND

Epidemiological studies have shown significant ethnic differences in coronary heart disease death rates with South Asians showing significantly greater coronary heart disease mortality than other groups.

PURPOSE

This research examined ethnic differences in cardiovascular reactivity (CVR) among Chinese, Malays and Indians in Singapore as well as a sample of Indians living in India.

METHODS

Experiment 1 examined differences across 303 Chinese, Malay and Indian undergraduates in Singapore, while Experiment 2 looked at differences in CVR between Indian participants from Singapore, and 145 Indians living in India. Systolic and diastolic blood pressure (SBP, DBP), heart rate (HR), cardiac index (CI) and total peripheral resistance index (TPRI) were measured during baselines and five laboratory tasks.

RESULTS

Ethnicity main effects for SBP and CI reactivity were obtained in Experiment 1, with Indians showing significantly lower BP and CI reactivity than the Chinese and Malays. Significant main effects for sex were found with females showing lower reactivity than males for TPRI, and greater reactivity than males for HR and CI. Experiment 2 found that participants from India showed higher reactivity for SBP, HR and CI, while Indian participants from Singapore showed higher TPRI reactivity. These differences, however, often varied by task.

CONCLUSIONS

These results point to differences in CVR among ethnic groups in Singapore as well as between Indians living in India and those living in Singapore. These differences may reflect cultural differences and need to be explored further with respect to their relationship to different rates of coronary heart disease among these groups.

Culture moderates the cardiovascular consequences of anger regulation strategy

PURPOSE

This research examined cultural differences in experiential and cardiovascular outcomes of three anger regulation strategies (expression, suppression and reappraisal).

METHODS

Forty-five Chinese and 45 Caucasian females participated in a laboratory experiment in which role play was used to induce anger. During this role play participants were instructed to either express or suppress their feelings or engage in cognitive reappraisal. Emotional experience was measured before and after the role play. Cardiovascular indices were measured continuously during the experiment.

RESULTS

Significant interactions were obtained such that Caucasians showed stronger cardiovascular responses to suppression than expression of anger whereas the opposite was true for Chinese.

CONCLUSIONS

These results demonstrate that physiological consequences of emotion regulation strategies vary by cultural background. Possible reasons as well as implications of these findings are discussed.

Nonadditive Genetic Effects on Hostility in South Korean Adolescent and Young Adult Twins

Hostility has been shown to be a vulnerability marker for various health problems. The present study examined genetic and environmental contributions to individual differences in hostility in South Korean adolescent and young adult twins. Seven hundred and nineteen same- and opposite-sex twin pairs aged from 13 to 23 years completed a hostility scale. The scalar sex-limitation model was applied to the data. The best fitting model indicated that 34% of the total variation of hostility was attributable to genetic factors operating in a nonadditive manner. The remaining 66% of the variance was associated with nonshared environmental influences and measurement error. These findings were largely consistent with results from previous twin studies of personality based on Caucasian twins, rendering support for the pervasive influence of genetic non-additivity on human personality traits and the generalization of the heritability of personality across human populations.

Sexual arousal in East Asian and Euro-Canadian women: a psychophysiological study

INTRODUCTION

Studies of ethnic differences in self-report measures of sexuality have shown East Asian women to be more sexually conservative and less sexually experienced than Caucasian women. There is also strong evidence supporting the notion of ethnic group differences in general measures of nonsexual psychophysiological arousal; however, there have been no previous studies exploring ethnicity and physiological sexual arousal.

AIM

The objective of this study was to explore group differences in self-reported and physiological sexual arousal in Euro-Canadian and East Asian women living in Canada; we also aimed to explore the association between level of acculturation (both mainstream and heritage) and sexual arousal in East Asian women only.

METHODS

Seventy-five women (N=38 Euro-Canadian, N=37 East Asian) completed a battery of questionnaires and underwent psychophysiological sexual arousal testing using the vaginal photoplethysmograph. They also completed a self-report measure of subjective arousal before and after erotic stimulus exposure.

MAIN OUTCOME MEASURES

All women completed the Female Sexual Function Index, Vancouver Index of Acculturation, and Sexual Beliefs and Information Questionnaire. Change in genital sexual arousal (vaginal pulse amplitude; VPA), and change in subjective sexual arousal were measured during exposure to erotic stimuli.

RESULTS

The groups did not differ in the percent increase in VPA induced by erotic stimuli, nor was there a correlation between VPA and subjective sexual arousal. Among East Asian women alone, neither heritage nor mainstream acculturation was correlated with change in VPA.

CONCLUSIONS

East Asian and Euro-Canadian women who show similar ratings of sexual behaviors and self-reported sexual arousal do not differ in physiological or subjective arousal induced by erotic stimuli in the laboratory.

Emotion Control Values and Responding to an Anger Provocation inAsian-American and European-American Individuals

The present research examined whether Asian-American (AA) versus European-American (EA) women differed in experiential, expressive, or autonomic physiological responding to a laboratory anger provocation and assessed the mediating role of values about emotional control. Results indicate that AA participants reported and behaviorally displayed less anger than EA participants, while there were no group differences in physiological responses. Observed differences in emotional responses were partially mediated by emotion control values, suggesting a potential mechanism for effects of cultural background on anger responding.

Coping with racism: a selective review of the literature and a theoretical and methodological critique

Racism is a stressor that contributes to racial/ethnic disparities in mental and physical health and to variations in these outcomes within racial and ethnic minority groups. The aim of this paper is to identify and discuss key issues in the study of individual-level strategies for coping with interpersonal racism. We begin with a discussion of the ways in which racism acts as a stressor and requires the mobilization of coping resources. Next, we examine available models for describing and conceptualizing strategies for coping with racism. Third, we discuss three major forms of coping: racial identity development, social support seeking and anger suppression and expression. We examine empirical support for the role of these coping strategies in buffering the impact of racism on specific health-related outcomes, including mental health (i.e., specifically, self-reported psychological distress and depressive symptoms), self-reported physical health, resting blood pressure levels, and cardiovascular reactivity to stressors. Careful examination of the effectiveness of individual-level coping strategies can guide future interventions on both the individual and community levels.

Damned if you do, damned if you don't: The differential effect of expression and inhibition of anger on cardiovascular recovery in Black and White males

Appropriate regulation of emotions is an important component of health. The physiological effects of coping with anger are a topic of particular interest. In a pioneering series of studies Hokanson found that the mode of anger expression following anger instigation had differential effects on vascular recovery. These differential effects were thought to be a result of social learning of avoidance responses. The present study examined this hypothesis in the context of ethnic differences in cardiovascular recovery responses to anger instigation. Twenty-four African American (AA) and 26 European American (EA) males engaged in two debates, one racially themed and one non-racially themed, with an EA confederate. Cardiovascular measures were recorded at baseline, during the debates and during 10-minute recovery periods following each debate. Anger expression preceding the recovery period was manipulated such that half the participants could express their anger toward the confederate and half had to inhibit their anger toward the confederate. Results showed that both AA and EA participants that inhibited their anger had delayed total peripheral resistance recovery. Importantly, for the other dependent variables differential recovery responses were observed such that EA participants that expressed their anger recovered more quickly whereas AA participants that expressed their anger recovered more slowly. These results are consistent with Hokanson's social learning theory of recovery from anger instigation and have important implications for research on emotion regulation and health.

Heart rate response after emotional picture presentation is modulated by interoceptive awareness

The perception of visceral signals plays a crucial role in many theories of emotions. The present study was designed to investigate the relationship between interoceptive awareness, emotional experience and heart rate responses in an emotional stimulation paradigm. Based on their performance in a heartbeat perception task 38 participants (16 males, 22 females) were classified as subjects with either high (n=19; 8 males) or low interoceptive awareness (n=19; 8 males). 120 pictures (40 pleasant, 40 unpleasant, 40 neutral slides) from the International Affective Picture System served as emotional stimuli. Heart rate changes were recorded during baseline and during slide presentation. After each slide, the subjects had to rate emotional valence and arousal on a 9-point self-report scale. Statistical analyses revealed significantly stronger heart rate responses to pleasant and unpleasant stimuli in subjects with high interoceptive awareness. Furthermore, subjects with high interoceptive awareness rated pleasant and unpleasant slides as significantly more arousing; no differences were found in the emotional valence ratings. Heartbeat perception scores correlated significantly positive with both the mean arousal rating and with the mean heart rate changes. Our results demonstrate a strong relationship between the perception of cardiac signals and the peripheral processing of emotional stimuli.
