The physiological and psychological effects of 2 human sex-steroid derived compounds, 4,16-androstadien-3-one (AND) and 1,3,5(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. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Drug overdose now exceeds car accidents as the leading cause of accidental death in the United States. Of those drug overdoses, a large percentage of the deaths are due to heroin and/or pharmaceutical overdose, specifically misuse of prescription opioid analgesics. It is imperative, then, that we understand the mechanisms that lead to opioid abuse and addiction. The rewarding actions of opioids are mediated largely by the mu-opioid receptor (MOR), and signaling by this receptor is modulated by various interacting proteins. The neurotransmitter dopamine also contributes to opioid reward, and opioid addiction has been linked to reduced expression of dopamine D2 receptors (D2R) in the brain. That said, it is not known if alterations in the expression of these proteins relate to drug exposure and/or to the "addiction-like" behavior exhibited for the drug. Here, we held total drug self-administration constant across acquisition and showed that reduced expression of the D2R and the MOR interacting protein, Wntless, in the medial prefrontal cortex was associated with greater addiction-like behavior for heroin in general and with a greater willingness to work for the drug in particular. In contrast, reduced expression of the D2R in the nucleus accumbens and hippocampus was correlated with greater seeking during signaled nonavailability of the drug. Taken together, these data link reduced expression of both the D2R and Wntless to the explicit motivation for the drug rather than to differences in total drug intake per se., ((c) 2015 APA, all rights reserved).)

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.

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.

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.

Thirty married couples were studied during naturalistic interactions to determine the extent to which variation in marital satisfaction could be accounted for by physiological and affective patterns between and within spouses. The authors hypothesized that (a) compared to nondistressed couples' interactions, distressed couples' interactions would show greater physiological interrelatedness or "linkage," more negative affect, and more reciprocity of negative affect and (b) these differences would be more pronounced when the interaction was high in conflict (discussing a marital problem) as opposed to low in conflict (discussing the events of the day). Heart rate, skin conductance, pulse transmission time, and somatic activity from both spouses were analyzed using bivariate time-series techniques to derive a measure of physiological linkage. Self-report affective data (obtained using a video-recall procedure) were analyzed using sequential analyses to derive a measure of affect reciprocity. The hypotheses were strongly supported; 60% of the variance in marital satisfaction was accounted for using measures of physiological linkage alone. Additional nonredundant variance was accounted for by the other physiological and affective measures.
