Hostility,oral contraceptive use,and cardiovascular reactivity in women

Abstract

Hostility, task instructions, social desirability and cardiovascular reactivity were investigated in a exploratory study of 70 female college students and employees. Women were administered the Videotaped Clinical Interview (VC1), the Marlowe-Crowne Social Desirability Scale (MC), the Cook-Medley Hostility Scale (CM), the Buss-Durkee Hostility Index (BD) and the Personal Attributes Questionnaire (PAQ) before undergoing a stressful discussion. Oral contraceptive users had significantly higher DBP at baseline. Based on PAQ scores, women were given instructions for the discussion task consistent or inconsistent with their gender-relevant styles. Instruction type predicted heart rate changes, and interacted with hostility to predict DBP reactivity. Interview-based hostility (VCI-H) was associated with increased DBP during the discussion task, as was being high hostile (low MC/high VCI-H). The CM and the BD had less association with heart rate and blood pressure changes. Oral contraceptive (OC) use was associated with higher SBP reactivity under stress, with highest SBP increases in the OC users concerned with social desirability. The complex interaction between trait dimensions like hostility, social desirability, and oral contraceptive use requires further investigation.     

Chronic stress influences cardiovascular and neuroendocrine responses during acute stress and recovery, especially in men.

This study tests the influence of chronic stress on cardiovascular and neuroendocrine responses to and recovery from acute stressors and whether the effects are gender specific. Sixty-two healthy, middle-aged persons (50% women) performed mental-arithmetic and public-speaking tasks and relaxed thereafter for 1 hr while their cardiovascular and neuroendocrine function was measured. Participants with higher levels of chronic stress showed lower systolic blood pressure (SBP) and epinephrine (E; men only) and marginally lower levels of norepinephrine (NE) responses to the tasks and showed lower levels of cortisol and marginally lower NE responses during recovery. Relative to women, men had high diastolic blood pressure (DBP) responses to the tasks and high SBP, DBP, and E responses during recovery. Gender differences in cardiovascular disease in midlife may be due to gender differences in the inability to recover quickly, in addition to enhanced acute-stress response.     

Neuroticism and cardiovascular response in women: evidence of effects on blood pressure recovery

Neuroticism is a unifying personality trait that underlies a number of psychosocial risk factors for cardiovascular disease. One means by which Neuroticism may influence health risk is through effects on cardiovascular reactivity and recovery. Eighty-six women scoring high or low in Neuroticism took part in a paired interpersonal stressor task with a laboratory confederate. Conditions differed on the basis of the confederate's interpersonal behavior: hostile, neutral, or friendly. Neuroticism interacted with condition to affect blood pressure recovery such that women high in Neuroticism showed less recovery following hostile interactions and greater recovery following friendly interactions. Main effects of Neuroticism on anger and anxiety reactivity were found. Results indicate that Neuroticism is relevant to cardiovascular health in the context of valenced social interactions. Implications for future study of Neuroticism and interpersonal stressors as risk factors for cardiovascular disease are discussed.     

The effects of analytical rumination, reappraisal, and distraction on anger experience

The manner in which individuals recall negative life events has important affective consequences. The present experiment investigated the effects of emotion regulation strategies on anger experience. One hundred and twenty-one undergraduates recalled an anger-inducing memory and were instructed to engage in either analytical rumination, cognitive reappraisal, or distraction for 20 minutes. In the remaining (control) condition, participants were instructed to write about their thoughts but were not given any emotion regulation instructions. Rumination maintained anger, whereas participants in the remaining conditions reported decreased anger following the writing task. Our results suggest that reappraisal facilitates adaptive processing of anger-inducing memories and distraction facilitates rapid reductions in anger experience. These findings have implications for the management of clinical populations that commonly experience difficulty with anger regulation.     

Dissociable lexical and phonological influences on serial recognition and serial recall

The impact of the lexicality of memory items on memory performance was compared in two paradigms, serial recall and serial recognition. Experiments 1 to 3 tested 7- and 8-year-old children. Memory accuracy was only mildly impaired in lists containing nonwords compared with words in a serial recognition task involving judgements of whether the items in two sequences were in the same order (Experiment 1), although a substantial advantage for word over nonword items from the same stimulus pool was found in serial recall (Experiment 2). A stronger influence of lexicality on serial recall than serial recognition was further demonstrated in Experiments 3A and 3B, and in 4A and 4B using adult participants. These experiments also established comparable degrees of sensitivity to the phonological similarity of the memory sequences in the two paradigms. The phonological similarity effect in serial recall was found to arise from increased phoneme order errors, whereas the lexicality effect was due principally to the greater frequency of phoneme identity errors for nonwords. It is proposed that the lexicality effect originates in the redintegration of item information just prior to recall, and that this process is largely bypassed in serial recognition.     

The influences of valence and arousal on judgments of learning and on recall

Much is known about how the emotional content of words affects memory for those words, but only recently have researchers begun to investigate whether emotional content influences metamemory—that is, learners’ assessments of what is or is not memorable. The present study replicated recent work demonstrating that judgments of learning (JOLs) do indeed reflect the superior memorability of words with emotional content. We further contrasted two hypotheses regarding this effect: a physiological account in which emotional words are judged to be more memorable because of their arousing properties, versus a cognitive account in which emotional words are judged to be more memorable because of their cognitive distinctiveness. Two results supported the latter account. First, both normed arousal (Exp. 1) and normed valence (Exp. 2) independently influenced JOLs, even though only an effect of arousal would be expected under a physiological account. Second, emotional content no longer influenced JOLs in a design (Exp. 3) that reduced the primary distinctiveness of emotional words by using a single list of words in which normed valence and arousal were varied continuously. These results suggest that the metamnemonic benefit of emotional words likely stems from cognitive factors.     

Hostility, anger, aggressiveness, and coronary heart disease: an interpersonal perspective on personality, emotion, and health

The related traits of hostility, anger, and aggressiveness have long been suggested as risk factors for coronary heart disease (CHD). Our prior review of this literature (Smith, 1992) found both considerable evidence in support of this hypothesis and important limitations that precluded firm conclusions. In the present review, we discuss recent research on the assessment of these traits, their association with CHD and longevity, and mechanisms possibly underlying the association. In doing so, we illustrate the value of the interpersonal tradition in personality psychology (Sullivan, 1953; Leary, 1957; Carson, 1969; Kiesler, 1996) for not only research on the health consequences of hostility, anger, and aggressiveness, but also for the general study of the effects of emotion, personality and other psychosocial characteristics on physical health.     

Mood regulation in depression: Differential effects of distraction and recall of happy memories on sad mood

Recent research suggests that the recall of positive memories plays an important role in mood regulation. In this study, the authors examined the ability of currently depressed, formerly depressed, and never-depressed participants to regulate sad mood through the recall of positive memories or through distraction. Although improvement in mood was found for all participants in response to distraction, under instructions to recall positive memories, never-depressed participants' moods improved, whereas formerly depressed participants' sad moods remained unchanged. It is important to note that depressed participants exhibited a worsening of their sad moods after recalling positive memories. These results suggest both that depression is associated with an impaired ability to use positive recall to regulate a sad mood and that this impairment continues to be evident following recovery.     

Automatic processing influences free recall: converging evidence from the process dissociation procedure and remember-know judgments

Dual-process theories of retrieval suggest that controlled and automatic processing contribute to memory performance. Free recall tests are often considered pure measures of recollection, assessing only the controlled process. We report two experiments demonstrating that automatic processes also influence free recall. Experiment 1 used inclusion and exclusion tasks to estimate recollection and automaticity in free recall, adopting a new variant of the process dissociation procedure. Dividing attention during study selectively reduced the recollection estimate but did not affect the automatic component. In Experiment 2, we replicated the results of Experiment 1, and subjects additionally reported remember–know–guess judgments during recall in the inclusion condition. In the latter task, dividing attention during study reduced remember judgments for studied items, but know responses were unaffected. Results from both methods indicated that free recall is partly driven by automatic processes. Thus, we conclude that retrieval in free recall tests is not driven solely by conscious recollection (or remembering) but also by automatic influences of the same sort believed to drive priming on implicit memory tests. Sometimes items come to mind without volition in free recall.     

Bottom-up influences on working memory: behavioral and electrophysiological distraction varies with distractor strength

The present study investigates bottom-up effects serving the optimal balance between focusing attention on relevant information and distractibility by potentially significant events outside the focus of attention. We tested whether distraction, indicated by behavioral and event-related brain potential (ERP) measures, varies with the strength of task-irrelevant deviances. Twenty subjects performed a tone-duration discrimination task (200 or 400 ms sinusoidal tones presented equiprobably). The stimuli were presented with frequent standard (p = 0.84; 1000 Hz) or infrequent deviant (p = 0.16) pitch. These task-irrelevant pitch changes consisted in a frequency increase/decrease of 1%, 3%, 5%, or 10%. Each of them resulted in prolonged reaction times (RT) in the duration discrimination task and elicited the MMN, P3a, and RON components of the ERP. Importantly, these measures did increase as a function of pitch deviance. Separating the individual trials on the 1% deviation level into trials with and without RT prolongation, i.e., behavioral distraction effect, revealed that both subgroups had similar MMN, but P3a and RON were confined to the trials with RT prolongation. Results are interpreted within a model relating preattentive deviance detection, distraction, and working memory.     

Hostility and facial affect recognition: effects of a cold pressor stressor on accuracy and cardiovascular reactivity

The effects of hostility and a cold pressor stressor on the accuracy of facial affect perception were examined in the present experiment. A mechanism whereby physiological arousal level is mediated by systems which also mediate accuracy of an individual’s interpretation of affective cues is described. Right-handed participants were classified as high hostile (N=28) or low hostile (N=28) using the Cook Medley Hostility Scale. The high-hostile group met joint selection criteria. Only high-hostile participants who showed cardiovascular reactivity to the cold pressor, with systolic BP change exceeding the group mean were included. Groups were further subdivided into cold pressor and non-cold pressor test conditions. It was predicted that high-hostile men, relative to low-hostile men, would show decreased perceptual accuracy when presented with happy, angry, and neutral facial configurations within the left visual field (LVF). Results indicated that high-hostile men were less accurate than low-hostile men in the LVF. Further, pre-stress accuracy scores in the high-hostile men were similar to the post-stress accuracy scores of the low-hostile men. The lateralization of affective function and the role of physiological arousal in affective facial perception are discussed.     

Cardiovascular health in women: the role of anger and its expression

The relationships between anger expression (in, out, and control) and cardiovascular health (emotional distress, cardiovascular symptoms reported, and preventive health behaviors) were analyzed in 327 women (range 17-60 years). The same criteria (N= 218), as well as blood pressure (BP) registered in medical checkups (N= 90) were recorded one year later. Four groups according to anger-in and anger-control scores, going from the most hostile (high anger-in and low anger-control) to the least hostile (low anger-in and high anger-control) were considered. The results indicated that the most hostile group, with the least adaptive anger expression, presented worst cardiovascular health than the other three groups, at both temporal moments. Furthermore, the presence of women with pathological BP levels was higher in the groups of high anger-in. These data ratify the role of anger expression, especially its repression (anger-in) and the lack of adequate canalization or control in women's cardiovascular health from a prospective design. Appropriate management of anger feelings and the practice of preventive health behaviors can protect women from cardiovascular problems.     

Experiential and physiological responses associated with anger and aggression in women and men

In a 2 × 2 × 2 factorial design, 48 male and female college students were either given a “sex-appropriate” provocation or were not provoked. Half of the subjects were then requested to give a “stream of consciousness” (SOC) report. Throughout the experiment, three physiological measures were monitored. Finally, all subjects delivered noxious sounds to their same-sex partner as part of a Buss-type learning task. No sex differences were found for subjects not giving the SOC report; provoked men and women were equally angry, hostile toward their partner, and displayed equal amounts of aggressive behavior. Provoked men reporting on their SOC, however, appeared to stimulate themselves to more aggression, whereas women seemed to adopt a nonhostile strategy for coping with their anger, thus reducing their inclination to behave aggressively. These patterns of results were closely paralleled by physiological changes. The relative validity of systolic and diastolic blood pressure as indicators of anger arousal was also discussed.     

Marital satisfaction, recovery from work, and diurnal cortisol among men and women.

DESIGN: Multilevel modeling was used to model relationships between salivary cortisol, daily diary ratings of work experiences, and Marital Adjustment Test scores (Locke & Wallace, 1959), in a sample of 60 adults who sampled saliva 4 times per day over 3 days. RESULTS: Among women but not men, marital satisfaction was significantly associated with a stronger basal cortisol cycle, with higher morning values and a steeper decline across the day. For women but not men, marital satisfaction moderated the within-subjects association between afternoon and evening cortisol level, such that marital quality appeared to bolster women's physiological recovery from work. For both men and women, evening cortisol was lower than usual on higher-workload days, and marital satisfaction augmented this association among women. Men showed higher evening cortisol after more distressing social experiences at work, an association that was strongest among men with higher marital satisfaction. CONCLUSION: This work has implications for the study of physiological recovery from work, and also suggests a pathway by which marital satisfaction influences allostatic load and physical health.     

Manipulating self-efficacy in the exercise environment in women: influences on affective responses.

Self-efficacy was experimentally manipulated in an exercise context, and its effect on affective responses was examined. College women (N = 46) were randomly assigned to a high- or low-efficacy condition, and efficacy expectations were manipulated by means of bogus feedback and graphs depicting contrived normative data. The manipulation successfully influenced affective responses, with participants in the high-efficacy group reporting more positive and less negative affect than did the low-efficacy group. Efficacy was significantly related to feeling-state responses during and after activity but only in the high-efficacy condition. The results suggest that self-efficacy can be manipulated and that these changes are related to the affective experience associated with exercise. Such findings may have important implications for the roles played by self-efficacy and affect in exercise adherence.     

Validity of perceptions during recovery from maximal exercise in men and women

The Borg Scale, widely used to measure perceptions of exercise, has not been validated for use during recovery. Heart rate was used as the validity criterion. 11 untrained men and 10 untrained women were run to exhaustion on a treadmill. Heart rate and recovery ratings were obtained at :15, :45, 1:15, 1:45, 2:30, 3:30 and 4:30 min. following exercise. No significant differences were observed between sexes for both heart rate and recovery ratings. Trend analysis showed recovery ratings to be linear between :45 and at 4:30 while heart rate is best described by two linear trends with a break point at 2:30. Percent recovery was significantly faster for recovery ratings at :45, 1:15, 1:45 and 4:30. Heart rate and recovery ratings were not significantly correlated at any time point. A perceptual scale should be designed which more closely approximates metabolic response during recovery.
