Behavioral regulation is a hallmark feature of executive functioning (EF). The present study investigated whether commonly used neuropsychological test measures of EF (i.e., working memory, Stroop, trail making, and verbal fluency) were related to ability to downregulate emotion both spontaneously and when instructed to suppress emotional expressions. To ensure a wide range of EF, 24 frontotemporal lobar degeneration patients, 7 Alzheimer's patients, and 17 neurologically normal controls participated. Participants were exposed to an acoustic startle stimulus (single aversive noise burst) under three conditions: (1) unwarned, (2) warned with no instructions (to measure spontaneous emotion downregulation), and (3) warned with instructions to suppress (to measure instructed emotion downregulation). Results indicated that higher verbal fluency scores were related to greater emotion regulation (operationalized as reduction in body movement and emotional facial behavior when warned of the impending startle) in both regulation conditions. No relationships were found between emotion regulation in these conditions and the other EF measures. We conclude that, of four commonly used measures of EF, verbal fluency best indexes the complex processes of monitoring, evaluation, and control necessary for successful emotion regulation, both spontaneously and following instructions to suppress.

Frontotemporal lobar degeneration (FTLD) is a neurodegenerative disease that dramatically alters social and emotional behavior. Recent work has suggested that self-conscious emotions (e.g., embarrassment) may be particularly vulnerable to disruption in this disease. Self-conscious emotions require the ability to monitor the self in relation to others. These abilities are thought to be subserved by brain regions (e.g., medial prefrontal, anterior cingulate, and insula) that are particularly vulnerable to damage in FTLD. This study examined emotional responding (expressive behavior, peripheral physiology, and subjective experience) in 24 FTLD patients and 16 cognitively normal control participants using a karaoke task known to elicit self-conscious emotion reliably and a nonemotional control task (isometric handgrip). Results indicated that FTLD patients showed diminished self-conscious emotional behavior (embarrassment and amusement) and diminished physiological responding while watching themselves singing. No differences were found between patients and controls in the nonemotional control task. These findings offer evidence of marked disruption of self-conscious emotional responding in FTLD. Diminished self-conscious emotional responding likely contributes significantly to social inappropriateness and other behavioral abnormalities in FTLD., (2008 APA, all rights reserved)

Previous research has shown that inhibiting emotion-expressive behavior (emotion suppression) leads to increased sympathetic activation of the cardiovascular system [Gross, J.J. and Levenson, R.W. (1993). Emotional suppression: physiology, self-report, and expressive behavior. J. Pers. Soc. Psychol. 64(6), 970-986]. Ethnic differences have been reported in how frequently suppression is used as an emotion regulation strategy [Gross, J.J. and John, O. (2003). Individual differences in two emotion regulation processes: implications for affect, relationships, and well-being. J. Pers. Soc. Psychol. 85(2), 348-362]; however, it remains unknown whether there are ethnic differences in the physiological consequences of suppression. To test this, 168 participants from four ethnic groups (African American, Chinese American, European American, Mexican American) watched a disgust-eliciting film clip; half were instructed to suppress their emotions and half simply watched the film. Consistent with previous research, suppression was associated with decreased facial behavior, increased cardiovascular activation, and no impact on subjective emotional experience. Ethnicity failed to moderate these effects, indicating the generality of the cardiovascular consequences of emotion suppression across ethnic background.

The relations among social information processing (SIP), cardiac activity, and antisocial behavior were investigated in adolescents over a 3-year period (from ages 16 to 18) in a community sample of 585 (48% female, 17% African American) participants. Antisocial behavior was assessed in all 3 years. Cardiac and SIP measures were collected between the first and second behavioral assessments. Cardiac measures assessed resting heart rate (RHR) and heart rate reactivity (HRR) as participants imagined themselves being victimized in hypothetical provocation situations portrayed via video vignettes. The findings were moderated by gender and supported a multiprocess model in which antisocial behavior is a function of trait-like low RHR (for male individuals only) and deviant SIP. In addition, deviant SIP mediated the effects of elevated HRR reactivity and elevated RHR on antisocial behavior (for male and female participants).

Background: Frontotemporal lobar degeneration (FTLD) is associated with a profound decline in social and emotional behavior; however, current understanding regarding the specific aspects of emotional functioning that are preserved and disrupted is limited., Objective: To assess preservation of function and deficits in two aspects of emotional processing (emotional reactivity and emotion recognition) in FTLD., Methods: Twenty-eight FTLD patients were compared with 16 controls in emotional reactivity (self-reported emotional experience, emotional facial behavior, and autonomic nervous system response to film stimuli) and emotion recognition (ability to identify a target emotion of fear, happy, or sad experienced by film characters). Additionally, the neural correlates of emotional reactivity and emotion recognition were investigated., Results: FTLD patients were comparable to controls in 1) emotional reactivity to the fear, happy, and sad film clips and 2) emotion recognition for the happy film clip. However, FTLD patients were significantly impaired compared with controls in emotion recognition for the fear and sad film clips. Volumetric analyses revealed that deficits in emotion recognition were associated with decreased lobar volumes in the frontal and temporal lobes., Conclusions: The socioemotional decline typically seen in frontotemporal lobar degeneration patients may result more from an inability to process certain emotions in other people than from deficits in emotional reactivity.

Social neuroscience is a new, interdisciplinary field devoted to understanding how biological systems implement social processes and behavior. Social neuroscience capitalizes on biological concepts and methods to inform and refine theories of social behavior, and it uses social and behavioral constructs and data to inform and refine theories of neural organization and function. We focus here on the progress and potential of social neuroscience in the area of mental health. Research in social neuroscience has grown dramatically in recent years. Among the most active areas of research we found are brain-imaging studies in normal children and adults; animal models of social behavior; studies of stroke patients; imaging studies of psychiatric patients; and research on social determinants of peripheral neural, neuroendocrine, and immunological processes. We also found that these areas of research are proceeding along largely independent trajectories. Our goals in this article are to review the development of this field, examine some currently promising approaches, identify obstacles and opportunities for future advances and integration, and consider how this research can inform work on the diagnosis and treatment of mental disorders., (© 2007 Association for Psychological Science.)

This study examined whether individuals from 4 major ethnic groups within the United States (African American, Chinese American, European American, and Mexican American) showed greater subjective, behavioral, and physiological responses to emotional film clips (amusement, sadness, and disgust) with actors from their own ethnic group (ethnically matched) compared with actors from the other 3 ethnic groups (ethnically mismatched). Evidence showed greater responsivity to ethnically matched films for African Americans and European Americans, with the largest effect for African Americans. These findings were consistent across both sex and level of cultural identification. Findings of ethnic difference notwithstanding, there were many areas in which ethnic differences were not found (e.g., little or no evidence was found of greater response to ethnically matched films in Chinese-American or Mexican- American participants). These findings indicate that the emotional response system clearly reacts to stimuli of diverse ethnic content; however, the system is also amenable to subtle "tuning" that allows for incrementally enhanced responding to members of one's own ethnic or cultural group., (Copyright 2006 APA, all rights reserved.)

Frontotemporal lobar degeneration (FTLD) is a neurodegenerative disease associated with dramatic changes in emotion. The precise nature of these changes is not fully understood; however, we believe that the most salient losses relate to self-relevant processing. Thus, FTLD patients exhibit emotional changes that are consistent with a reduction in self-monitoring, self-awareness and the ability to place the self in a social context. In contrast, other more primitive aspects of the emotional system may remain relatively intact. The startle response is a useful way to examine the precise nature of emotional deficits in neurological patients. In addition to a stereotyped defensive response (characterized by negative emotional facial behaviour and physiological activation), in many individuals it also evokes embarrassment, a self-conscious emotional response. Embarrassment seems to occur as the person becomes aware that the reaction to the startle was excessive and was observed by others. Because the self-conscious response depends on certain regions in frontal cortex, we expected that FTLD patients would have specific deficits in their self-conscious response. To test this notion, we examined the response of 30 FTLD patients and 23 cognitively normal controls to a loud, unexpected acoustic startle stimulus (115-dB burst of white noise). Emotional behaviours were measured along with an assessment of somatic, electrodermal, cardiovascular and respiratory responses. Results indicated that FTLD patients and controls were similar in terms of physiological responses and negative emotional facial behaviour to the startle, indicating that the defensive aspect of the startle was preserved. However, there were profound differences in the self-conscious response. FTLD patients showed significantly fewer facial signs of embarrassment than controls. This deficit in self-conscious response could not be explained by sex, cognitive status, age, education, medication, or differences in the negative emotional behaviour or physiological response. Thus, the emotional deficit in FTLD patients' response to the startle suggests a reduction in self-consciousness. These findings suggest that the emotional deficit in FTLD may be most profound in higher-order processes akin to those involved in the generation of embarrassment. These deficits are consistent with neural loss in the medial prefrontal cortex, which may play an important role in the production of self-conscious emotions. Disrupted self-conscious emotions in FTLD patients may have clinical importance because these deficits may underlie some of the socially inappropriate behaviours that are common in these patients.

To examine the relative influence of cultural and temperamental factors on emotional response, we compared the emotional behavior, reports of emotional experience, and autonomic responses of 50 European American (EA) and 48 Chinese American (CA) college-age dating couples during conversations about conflicts in their relationships. EA couples showed more positive and less negative emotional behavior than did CA couples, despite similarities in reports of emotional experience and autonomic reactivity. Group differences in emotional behavior were mediated by cultural (values and practices) but not temperamental factors (neuroticism and extraversion). Collapsing across groups, cultural factors accounted for greater variance in emotional behavior but lesser variance in reports of emotional experience compared with temperamental factors. Together, these findings suggest that the relative influence of cultural and temperamental factors on emotion varies by response component., ((c) 2006 APA, all rights reserved)

Previous studies have shown that inhibiting negative or positive emotion-expressive behavior leads to increased sympathetic activation. Inhibiting facial behavior while in an affectively neutral state has no such physiological consequences. This suggests that there may be something special about inhibiting emotion-expressive behavior. To test the boundary conditions of the suppression effect, acoustic startles were delivered to 252 participants in three experimental groups. Participants in one group received unanticipated startles. Participants in the other two groups were told that after a 20-s countdown a loud noise would occur; participants in one of these groups were further told to inhibit their expressive behavior. Results indicated that startle suppression increased sympathetic activation. These findings extend prior work on emotion suppression, and suggest that inhibiting other biologically based responses also may be physiologically taxing.

Neurodegenerative diseases frequently affect brain regions important for emotional processing, offering a valuable opportunity to study the effects of brain injury on emotion. The current study examined the neuroanatomical correlates of impaired recognition of emotions in patients with neurodegenerative disease. Performance on recognition of facial expressions, as measured by the Florida Affect Battery, was correlated with regional changes in gray matter tissue content in 50 patients with neurodegenerative disease using voxel-based morphometry. Recognition accuracy in the group was poor for negative emotions (fear, anger and sadness) and good for happiness, consistent with previous studies. For negative emotions, a region in the right lateral inferior temporal gyrus (Brodman's area (BA) 20) extending into the right middle temporal gyrus (BA 21) was correlated with accuracy. This effect appeared to be strongest for sadness, which was also independently correlated with atrophy in the superior temporal gyrus. These data suggest that regions in the right lateral and inferolateral temporal lobe are important for visual processing of negative emotions from faces and that functioning of this right temporal network is most critical for recognition of sad faces.

Ethnographic accounts suggest that emotions are moderated in Chinese cultures and expressed openly in Mexican cultures. The authors tested this notion by comparing subjective, behavioral, and physiological aspects of emotional responses to 3 (warned, unwarned, instructed to inhibit responding) aversive acoustic startle stimuli in 95 Chinese Americans and 64 Mexican Americans. Subjective reports were consistent with ethnographic accounts; Chinese Americans reported experiencing significantly less emotion than Mexican Americans across all 3 startle conditions. Evidence from a nonemotional task suggested that these differences were not artifacts of cultural differences in the use of rating scales. Few cultural differences were found in emotional behavior or physiology, suggesting that these aspects of emotion are less susceptible to cultural influence.

Emotion theories commonly postulate that emotions impose coherence across multiple response systems. However, empirical support for this coherence postulate is surprisingly limited. In the present study, the authors (a) examined the within-individual associations among experiential, facial behavioral, and peripheral physiological responses during emotional responding and (b) assessed whether emotion intensity moderates these associations. Experiential, behavioral, and physiological responses were measured second-by-second during a film that induced amusement and sadness. Results indicate that experience and behavior were highly associated but that physiological responses were only modestly associated with experience and behavior. Intensity of amusement experience was associated with greater coherence between behavior and physiological responding; intensity of sadness experience was not. These findings provide new evidence about response system coherence in emotions.

This study investigated age differences in the ability to suppress and amplify expressive behavior during emotional arousal. Young and old participants viewed 3 film clips about medical procedures while their behavioral, autonomic, and subjective responses were recorded. Half of the participants viewed all 3 films without additional instructions; the other half was asked to suppress and amplify their behavioral expression during the 2nd and 3rd films. Except for heart rate, suppression and amplification produced similar patterns of autonomic activation. Neither suppression nor amplification had effects on self-reported emotion. There were no age differences in the ability to suppress or amplify emotional expression or in their physiological or subjective consequences. Considering that older people's unregulated reactivity was lower than that of young adults, suppression may have been easier and amplification more difficult for older adults. Voluntary emotion regulation might be one domain of human performance that is spared from age-related losses.

The effects of sniffing different concentrations of the human sex-steroid derived compound 4,16-androstadien-3-one (AND) on autonomic nervous system function and mood were measured in 60 subjects. The effects were sex-specific and concentration-dependent. Only high concentrations of AND (0.00625 M) increased positive mood (p < 0.03) and decreased negative mood (p < 0.05) in women compared to men, and had sympathetic-like effects in women (p < 0.003), and parasympathetic-like effects in men (p < 0.05). These findings further implicate AND in chemical communication between humans, but pose questions as to the path by which AND is transduced, whether through chemical sensing or transdermal diffusion.

Damage to the orbital prefrontal cortex has been implicated in selectively diminishing electrodermal autonomic nervous system responses to anticipated punishing stimuli (e.g., losing money; Bechara, Damasio, & Damasio, 2000), but not to unanticipated punishing stimuli (e.g., loud noises; Damasio, Tranel, & Damasio, 1990). We extended this research by examining the effects of orbitofrontal damage on emotional responses to unanticipated and anticipated acoustic startles and collecting a more extensive set of physiological measures, emotional facial behavior, and self-reported emotional experience. Consistent with previous research, patients showed intact physiology to an unanticipated startle but failed to show appropriate anticipatory cardiovascular responses (patients' heart rates decreased, controls' increased). In addition, patients displayed more surprise facial behavior and reported marginally more fear than did controls in response to the unanticipated startle. Thus, orbitofrontal damage may compromise the ability to anticipate physiologically the onset of aversive stimuli, despite intact or enhanced emotional responses when such stimuli occur unexpectedly.

Recent studies have suggested that the frontal and temporal variants of frontotemporal dementia (fvFTD and tvFTD) are both associated with impairments in emotional processing. However, the degree and type of emotional processing deficits in the two syndromes have not been previously compared. We used the Florida Affect Battery to examine recognition of facial expressions of emotion in fvFTD and tvFTD patients who have no evidence of visual perceptual difficulties for faces. In general, both groups were impaired at recognizing emotions compared with age-matched controls. In tvFTD, this deficit was limited to emotions with a negative valence (sadness, anger, fear), while fvFTD patients showed impairment for positive valence (happiness) as well. These results suggest that damage to frontal lobe regions in FTD may lead to more profound impairment in recognition of emotion than when damage is more limited to the temporal lobe., (Copyright 2004 S. Karger AG, Basel)

The autonomic nervous system (ANS) plays a critical role in emotion, providing metabolic support for adaptive action, generating appearance changes with high signal value for conspecifics, and producing visceral sensations that shape subjective emotional experience. In this chapter, I consider several of the most important ways that the ANS is involved in emotion, including: (a) peripheral activation of emotion; (b) autonomic influences on emotional language and the labeling of subjective emotional experience; (c) positive emotion and autonomic soothing; (d) expressive signs of autonomic origin; (e) autonomic substrates of emotional contagion and empathy; and (f) autonomic consequences of emotion regulation. For each, I describe relevant research from our laboratory and discuss implications for an evolutionary account of emotion. In these and many other ways the autonomic architecture of human emotion has evolved not only to move blood and tears in the service of fears, but also to provide us with a rich set of tools that help us communicate and signal the nature of our internal emotional experiences, understand the emotions of others, calm ourselves and others, and give us some modicum of control over harmful and unproductive emotions.

The physiological and psychological effects of 2 human sex-steroid derived compounds, 4.16-androstadien-3-one (AND) and l,3,5(10),16-estratetraen-3-ol(EST) were measured in 24 subjects who participated in a within-subjects, double-blind experiment. A dissociation was evident in the physiological effects of AND, in that it increased physiological arousal in women but decreased it in men. EST did not significantly affect physiological arousal in women or men. Neither compound significantly affected mood. AND is an androgen derivative that is the most prevalent androstene in human male sweat, male axillary hair, and on the male axillary skin surface. The authors argue that AND's opposite effects on physiology in men and women further implicate this compound in chemical communication between humans., ((c) 2003 APA)

Emotional responses (physiology, self-report, and facial expression) of 12 depressed and 10 nondepressed Spanish-speaking Latinas during sad and amusing film clips of human and animal content were compared. Depressed Latinas demonstrated less electrodermal reactivity across all the film clips and displayed fewer social smiles during the amusing-human film clip than nondepressed Latinas. No differences emerged for cardiovascular measures, reports of emotion, or facial expressions of happiness and negative emotion. Observed differences in electrodermal reactivity are similar to results from previous studies of Anglo Americans, suggesting that reduced electrodermal activity may be linked to depression across cultures. The findings also suggest that, for Latinas, depression may selectively alter expressions that serve interpersonal functions.

A sample of committed gay and lesbian cohabiting couples engaged in two conversations after being apart for at least 8 hours: (a) an events of the day conversation and (b) a conflict resolution conversation. Physiological data were collected during the conversations and a videotape record was made. Couples viewed the videotapes and rated their affect during the interaction. The video records were coded with a system that categorized specific affects displayed. Models derived from physiology, from the perception of interaction, and from specific affective behavior were related to relationship satisfaction, and to the prediction of relationship dissolution over a 12-year period. Results supported previous findings that satisfaction and stability in gay and lesbian relationships are related to similar emotional qualities as in heterosexual relationships.

Two samples of committed gay and lesbian cohabiting couples and two samples of married couples (couples in which the woman presented the conflict issue to the man, and couples in which the man presented the conflict issue to the woman) engaged in three conversations: (1) an events of the day conversation (after being apart for at least 8 hours), (2) a conflict resolution conversation, and (3) a pleasant topic conversation. The observational data were coded with a system that categorized specific affects displayed. Data were weighted and two time-series created, one for the husband and one of the wife. The time series were modeled with nonlinear difference equations (Cook et al., 1995), and parameters were estimated that indexed uninfluenced steady state, influenced steady state, emotional inertia, repair effectiveness and threshold, and the power of positive and negative affect of one partner to affect the other partner.

Frontotemporal dementia (FTD) is a neurodegenerative disease characterized by behavioural disorders that suggest abnormalities of emotional processing. Patients with the temporal variant of FTD (tvFTD) are particularly at risk for developing deficits in emotional processing secondary to atrophy in the amygdala, anterior temporal cortex (ATC) and orbital frontal cortex (OFC), structures that are components of the brain's emotional processing systems. In addition, previous studies have suggested that predominantly right, as opposed to left temporal atrophy is more likely to be associated with behavioural and emotional impairments in tvFTD. However, emotional processing has never been assessed directly in this group. We examined one aspect of emotional processing, namely the comprehension of facial expressions of emotion (emotional comprehension) in nine individuals with tvFTD, and correlated performance on this measure with atrophy (as measured from T(1)-weighted MRI scans by region of interest analysis) in the amygdala, ATC and OFC. Compared with age-matched controls, the tvFTD group was impaired in emotional comprehension, with more severe impairment for emotions with negative valence, including sadness, anger and fear, than for happiness. Emotional comprehension was correlated with atrophy in the right amygdala and the right OFC, and not with atrophy in other structures. When individual profiles of amygdala atrophy were examined across patients and compared with control values, right amygdala atrophy was always accompanied by left amygdala atrophy, whereas patients with volume loss in the left amygdala could have normal or decreased right amygdala volumes. Thus, emotional comprehension appeared to be most impaired when bilateral amygdala atrophy was present, and was not associated with the degree of left amygdala atrophy. Our data indicate that tvFTD is associated with impairments in emotional processing that may underlie some behavioural problems in this disorder, and that the emergence of such deficits depends on the specific pattern of anatomical injury. These results have implications both for the clinical presentation in tvFTD patients and for the study of the neuroanatomical basis of emotion.

Boiten (1996) used the Directed Facial Action task (a task we developed in which participants follow instructions, based on theory about how emotion is expressed in the face, to move facial muscles deliberately to produce different facial configurations) to investigate heart rate differences among six emotional configurations. Boiten's findings closely replicated ours (Levenson, Ekman, & Friesen, 1990) in terms of heart rate change, self-reported emotion, and rated difficulty during the configurations. Boiten concluded that differences in difficulty were responsible for found differences in heart rate; in contrast, we had concluded that heart rate findings could not be explained in this manner. In this paper, we argue that neither Boiten nor we did the critical analyses needed to determine whether heart rate changes were mediated in this way. Performing these analyses, we conclude that neither reported difficulty nor two other potential mediators (time required to make the facial configurations; activity of nonfacial muscles) mediated the heart rate differences that we found between emotional configurations in the Directed Facial Action task.

This article examines 14-year longitudinal data and attempts to create a post hoc model that uses Time-1 data to "predict" the length of time the marriage will last. The sample consists of the 21 couples (of 79 studied) who divorced over a 14-year period. A two-factor model is proposed. One factor is the amount of unregulated volatile positive and negative affect in the marriage, and this factor predicts a short marriage length for the divorcing couples. A second factor is called "neutral affective style," and this factor predicts a long marriage length for the divorcing couples. This model is compared to a Time-1 model of ailing marriage in which Time-1 marital satisfaction is used to predict the timing of divorce.

Previously, the authors found that during idiosyncratic emotional events (relived emotions, discussions about marital conflict), older European American adults demonstrated smaller changes in cardiovascular responding than their younger counterparts (R. W. Levenson, L. L. Carstensen, W. V. Friesen, & P. Ekman, 1991; R. W. Levenson, L. L. Carstensen, & J. M. Gottman, 1994). This study examined whether such differences held when the emotional events were standardized, and whether they extend to another cultural group. Forty-eight old (70-85 years) and 48 young (20-34 years) European Americans and Chinese Americans viewed sad and amusing film clips in the laboratory while their cardiovascular, subjective (online and retrospective), and behavioral responses were measured. Consistent with previous findings, older participants evidenced smaller changes in cardiovascular responding than did younger participants during the film clips. Consistent with earlier reports, old and young participants did not differ in most subjective and behavioral responses to the films. No cultural differences were found.

Marital interaction has primarily been examined in the context of conflict resolution. This study investigated the predictive ability of couples to rebound from marital conflict in a subsequent positive conversation. Results showed that there was a great deal of consistency in affect across both conversations. Also examined was the ability of affective interaction to predict divorce over a 4-year period, separately in each of the two conversations. It was possible to predict divorce using affective variables from each conversation, with 82.6% accuracy from the conflict conversation and with 92.7% accuracy from the positive rebound conversation.

This is a report on what predicts the deterioration of affective marital interaction over a 4-year period. Four models were compared for their ability to predict Time-2 dysfunctional marital interaction (a set of reliable predictors of marital dissolution). These four models were: (1) baseline physiology at Time-1; (2) interaction physiology at Time-1; (3) a balance model based on the ratio of positivity to negativity at Time-1; and, (4) cognitions about the relationship operationalized from our coding of the Oral History Interview. All four models predicted Time-2 dysfunctional marital interaction. All four models were also able to predict change, operationalized as predicting Time-2 interaction, controlling for Time-1 interaction, that is, using a covariance regression analysis. The most powerful model in predicting change was the balance ratio model.

This is a report of the degree of stability in affective marital interaction over a 4-year period. There were statistically significant levels of stability in overall emotionality, and in positive and negative affect, particularly for wives. There was also stability for specific affects but, except for humor and listener backchannels, these varied with gender. Women were more stable than men in overall negative and positive affect. Men were more stable than women in belligerence, contempt, and tension/fear. Women were more stable than men in whining.

Two studies tested the hypothesis that certain positive emotions speed recovery from the cardiovascular sequelae of negative emotions. In Study 1, 60 subjects (Ss) viewed an initial fear-eliciting film, and were randomly assigned to view a secondary film that elicited: (a) contentment; (b) amusement; (c) neutrality; or (d) sadness. Compared to Ss who viewed the neutral and sad secondary films, those who viewed the positive films exhibited more rapid returns to pre-film levels of cardiovascular activation. In Study 2, 72 Ss viewed a film known to elicit sadness. Fifty Ss spontaneously smiled at least once while viewing this film. Compared to Ss who did not smile, those who smiled exhibited more rapid returns to pre-film levels of cardiovascular activation. We discuss these findings in terms of emotion theory and possible health-promoting functions of positive emotions.

Emotion regulation plays a central role in mental health and illness, but little is known about even the most basic forms of emotion regulation. To examine the acute effects of inhibiting negative and positive emotion, we asked 180 female participants to watch sad, neutral, and amusing films under 1 of 2 conditions. Suppression participants (N = 90) inhibited their expressive behavior while watching the films; no suppression participants (N = 90) simply watched the films. Suppression diminished expressive behavior in all 3 films and decreased amusement self-reports in sad and amusing films. Physiologically, suppression had no effect in the neutral film, but clear effects in both negative and positive emotional films, including increased sympathetic activation of the cardiovascular system. On the basis of these findings, we suggest several ways emotional inhibition may influence psychological functioning.

In exploring the emotional climate of long-term marriages, this study used an observational coding system to identify specific emotional behaviors expressed by middle-aged and older spouses during discussions of a marital problem. One hundred and fifty-six couples differing in age and marital satisfaction were studied. Emotional behaviors expressed by couples differed as a function of age, gender, and marital satisfaction. In older couples, the resolution of conflict was less emotionally negative and more affectionate than in middle-aged marriages. Differences between husbands and wives and between happy and unhappy marriages were also found. Wives were more affectively negative than husbands, whereas husbands were more defensive than wives, and unhappy marriages involved greater exchange of negative affect than happy marriages.

Two conflicting views have emerged as to why people cry when they are sad. One suggests that crying serves homeostasis by facilitating recovery; the other suggests that crying produces an aversive high-arousal state that motivates behavior aimed at ending the tears. To test hypotheses drawn from these views, we showed a short film known to elicit sadness to 150 women. During this film, 33 subjects spontaneously cried and 117 did not. Subjects who cried exhibited more expressive behavior and reported feeling more sadness and pain than did subjects who did not cry. Crying also was associated with increases in somatic and autonomic nervous system activity. The increases in autonomic activity could not be accounted for solely by the increases in somatic activity. Crying is thus associated with an aversive state, including negative emotion and a complex mixture of sympathetic, parasympathetic, and somatic activation, and we speculate about the functional implications of these findings.

Self-reported affect and autonomic and somatic physiology were studied during three 15-min conversations (events of the day, problem area, pleasant topic) in a sample of 151 couples in long-term marriages. Couples differed in age (40-50 or 60-70) and marital satisfaction (satisfied or dissatisfied). Marital interaction in older couples was associated with more affective positivity and lower physiological arousal (even when controlling for affective differences) than in middle-age couples. As has previously been found with younger couples, marital dissatisfaction was associated with less positive affect, greater negative affect, and greater negative affect reciprocity. In terms of the relation between physiological arousal and affective experience, husbands reported feeling more negative the more they were physiologically aroused; for wives, affect and arousal were not correlated. These findings are related to theories of socioemotional change with age and of gender differences in marital behavior and health.

Long-term marriages (N = 156) varying in spouses' age (40-50 years or 60-70 years) and relative marital satisfaction (satisfied and dissatisfied) were studied. Spouses independently completed demographic, marital, and health questionnaires and then participated in a laboratory-based procedure focused on areas of conflict and sources of pleasure. Findings supported a positive view of older marriages. Compared with middle-aged marriages, older couples evidenced (a) reduced potential for conflict and greater potential for pleasure in several areas (including children), (b) equivalent levels of overall mental and physical health, and (c) lesser gender differences in sources of pleasure. The relation between marital satisfaction and health was stronger for women than for men. In satisfied marriages, wives' and husbands' health was equivalent; in dissatisfied marriages, wives reported more mental and physical health problems than did their husbands.

This study examined the effects of emotional suppression, a form of emotion regulation defined as the conscious inhibition of emotional expressive behavior while emotionally aroused. Ss (43 men and 42 women) watched a short disgust-eliciting film while their behavioral, physiological, and subjective responses were recorded. Ss were told to watch the film (no suppression condition) or to watch the film while behaving "in such a way that a person watching you would not know you were feeling anything" (suppression condition). Suppression reduced expressive behavior and produced a mixed physiological state characterized by decreased somatic activity and decreased heart rate, along with increased blinking and indications of increased sympathetic nervous system activity (in other cardiovascular measures and in electrodermal responding). Suppression had no impact on the subjective experience of emotion. There were no sex differences in the effects of suppression.

Seventy-three married couples were studied in 1983 and 1987. To identify marital processes associated with dissolution, a balance theory of marriage was used to generate 1 variable for dividing couples into regulated and nonregulated groups. For studying the precursors of divorce, a "cascade" model of marital dissolution, which forms a Guttman-like scale, received preliminary support. Compared with regulated couples, nonregulated couples had (a) marital problems rated as more severe (Time 1); (b) lower marital satisfaction (Time 1 and Time 2); (c) poorer health (Time 2); (d) smaller finger pulse amplitudes (wives); (e) more negative ratings for interactions; (f) more negative emotional expression; (g) less positive emotional expression; (h) more stubbornness and withdrawal from interaction; (i) greater defensiveness; and (j) greater risk for marital dissolution (lower marital satisfaction and higher incidence of consideration of dissolution and of actual separation).

The relation between empathy (defined as the ability to perceive accurately how another person is feeling) and physiology was studied in 31 Ss. Ss viewed 15-min martial interactions and used a rating dial to indicate continuously how they thought a designated spouse was feeling. Rating accuracy was determined by comparing Ss' ratings with identical self-ratings obtained previously from the target spouse. Physiological linkage between S and target was determined using bivariate time-series analyses applied to 5 autonomic and somatic measures obtained from the S during the rating task and from the target spouse during the original conversation. Accuracy of rating negative emotion was greatest when S and target evidenced high levels of physiological linkage across time. Accuracy of detecting positive emotion was related to a state of low cardiovascular around in the S, but not to physiological linkage between S and target.

Physiology and emotional experience were studied in the Minangkabau of West Sumatra, a matrilineal, Moslem, agrarian culture with strong proscriptions against public displays of negative emotion. Forty-six Minangkabau men were instructed to contract facial muscles into prototypical configurations of 5 emotions. In comparison with a group of 62 Ss from the United States, cross-cultural consistencies were found in (a) autonomic nervous system (ANS) differences between emotions and (b) high configuration quality being associated with increased ANS differentiation and increased report of emotional experience. These findings provide the first evidence that these patterns of emotion-specific ANS activity and the capacity of voluntary facial action to generate this activity are not unique to American culture.

Emotion-specific autonomic nervous system (ANS) activity was studied in 20 elderly people (age 71-83 years, M = 77) who followed muscle-by-muscle instructions for constructing facial prototypes of emotional expressions and relived past emotional experiences. Results indicated that (a) patterns of emotion-specific ANS activity produced by these tasks closely resembled those found in other studies with younger Ss, (b) the magnitude of change in ANS measures was smaller in older than in younger Ss, (c) patterns of emotion-specific ANS activity showed generality across the 2 modes of elicitation, (d) emotion self-reports and spontaneous production of emotional facial expressions that occurred during relived emotional memories were comparable with those found in younger Ss, (e) elderly men and women did not differ in emotional physiology or facial expression, and (f) elderly women reported experiencing more intense emotions when reliving emotional memories than did elderly men.

Four experiments were conducted to determine whether voluntarily produced emotional facial configurations are associated with differentiated patterns of autonomic activity, and if so, how this might be mediated. Subjects received muscle-by-muscle instructions and coaching to produce facial configurations for anger, disgust, fear, happiness, sadness, and surprise while heart rate, skin conductance, finger temperature, and somatic activity were monitored. Results indicated that voluntary facial activity produced significant levels of subjective experience of the associated emotion, and that autonomic distinctions among emotions: (a) were found both between negative and positive emotions and among negative emotions, (b) were consistent between group and individual subjects' data, (c) were found in both male and female subjects, (d) were found in both specialized (actors, scientists) and nonspecialized populations, (e) were stronger when the voluntary facial configurations most closely resembled actual emotional expressions, and (f) were stronger when experience of the associated emotion was reported. The capacity of voluntary facial activity to generate emotion-specific autonomic activity: (a) did not require subjects to see facial expressions (either in a mirror or on an experimenter's face), and (b) could not be explained by differences in the difficulty of making the expressions or by differences in concomitant somatic activity.

Cardiovascular and other responses of stress of subjects considered to be at risk for coronary heart disease (CHD) were studied in order to evaluate two hypothesized pathways in the link between CHD risk factors and the disease process. Forty-seven male subjects with and without a parental history of CHD and with either the Type A or Type B behavior pattern were exposed to two psychological stressors (reaction time and Stroop Color-World test) and one physical stressor (isometric hand grip). Subjects with a parental history of CHD showed larger finger pulse amplitude responses to the two psychosocial stressors, and Type A subjects had larger diastolic blood pressure responses to all three stressors. These results indicated that subjects at greater risk for CHD had more substantial peripheral vascular responses to the stressors compared to low risk subjects; there were no differences in sympathetic cardiac responses related to contractility. The results are discussed in terms of potential mediating mechanisms in the development of CHD.

In 1980, 30 married couples had engaged in a low-conflict and a high-conflict conversational interaction while continuous physiological data were obtained. In a separate session each spouse had provided a continuous self-report of affect while viewing the videotape of the interaction. In 1983, 19 of these couples were re-located to determine the change in relationship satisfaction that had occurred over the preceding 3 years. A broadly based pattern of physiological arousal (across spouses, interaction segments, and physiological measures) in 1980 was found to predict decline in marital satisfaction; the more aroused the couple was during the 1980 interactions, the more their marital satisfaction declined over the ensuing 3 years. Several affective variables also predicted decline in marital satisfaction, including a pronounced sex difference in negative affect reciprocity: Marital satisfaction declined most when husbands did not reciprocate their wives' negative affect, and when wives did reciprocate their husbands' negative affect.

This study assessed the effects of natural expressive tendencies on physiological response to stress. Male undergraduates were unobtrusively observed while watching a stressor videotape. On the basis of the subjects' facial responsiveness to the film, a group of 23 natural expressers and 22 natural inhibitors were selected and exposed to a threat of shock situation during which heart rate, respiration rate, skin conductance, and facial expressions were monitored. In accord with the discharge model of emotion, natural inhibitors were less facially expressive and more physiologically reactive to the shock threat than were natural expressers. The results also demonstrated that overt expressivity is stable over time and situation. On personality measures, natural expressers scored significantly higher on Mehrabian's empathic tendency scale, thus supporting the efficacy of this paper-and-pencil instrument as a measure of non-verbal responsiveness. The two groups did not differ on measures of self-esteem, introversion--extraversion, or locus of control. The results are discussed in terms of the discharge model as a descriptive metaphor and not a causal theory.

Emotion-specific activity in the autonomic nervous system was generated by constructing facial prototypes of emotion muscle by muscle and by reliving past emotional experiences. The autonomic activity produced distinguished not only between positive and negative emotions, but also among negative emotions. This finding challenges emotion theories that have proposed autonomic activity to be undifferentiated or that have failed to address the implications of autonomic differentiation in emotion.
