40 chronic schizophrenic patients had their psychophysiological responses to 1 of 2 tension-arousing movies recorded. Following assignment to drug (thiordizane) or placebo status for 1 wk, they were retested on a similar film. The results were that the drug Ss showed a decrease in skin resistance and heart rate but not finger-pulse volume over their responses to the 1st showing while the placebo group showed opposite trends. Interview data collected after the films indicated no correlation between the autonomic changes and plot comprehension. Pilot work on word-association test responses indicates that the drug group showed a decrease while the placebo group showed an increase in idiosyncratic responses.

On the basis of studies finding heart rate deceleration among severely violent (SV) batterers (J. M. Gottman et al., 1995) and unsuccessful psychopaths (S. S. Ishikawa, A. Raine, T. Lencz, S. Bihrle, & L. Lacasse, 2001), this study compares the physiological reactivity of SV batterers (n = 35) with low-level violent (LLV) batterers (n = 37) and nonviolent men (n = 21) during 2 laboratory tasks. Men's heart rate and skin conductance level were recorded during baseline, a conflict discussion, and a standardized anger induction. Results suggest that autonomic hyporeactivity is a risk marker for antisocial features among SV men, whereas autonomic hyperreactivity is a risk marker among LLV men. Psychophysiological responding appears to be a stronger correlate of general antisocial behavior than of intimate partner abuse. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

This research reports age and gender differences in cardiac reactivity and subjective responses to the induction of autobiographical memories related to anger, fear, sadness, and happiness. Heart rate (HR) and subjective state were assessed at baseline and after the induction of each emotion in 113 individuals (61 men, 52 women; 66% European American, 34% African American) ranging in age from 15 to 88 years (M = 50.0; SD = 20.2). Cardiac reactivity was lower in older individuals; however, for anger and fear, these age effects were significantly more pronounced for the women than the men. There were no gender differences in subjective responses, however, suggesting that the lower cardiac reactivity found among older people is dependent on gender and the specific emotion assessed.

Marital strain confers risk of cardiovascular disease (CVD), perhaps though cardiovascular reactivity (CVR) to stressful marital interactions. CVR to marital stressors may differ between middle-age and older adults, and types of marital interactions that evoke CVR may also differ across these age groups, as relationship contexts and stressors differ with age. The authors examined cardiovascular responses to a marital conflict discussion and collaborative problem solving in 300 middle-aged and older married couples. Marital conflict evoked greater increases in blood pressure, cardiac output, and cardiac sympathetic activation than did collaboration. Older couples displayed smaller heart rate responses to conflict than did middle-aged couples but larger blood pressure responses to collaboration—especially in older men. These effects were maintained during a posttask recovery period. Women did not display greater CVR than men on any measure or in either interaction context, though they did display greater parasympathetic withdrawal. CVR to marital conflict could contribute to the association of marital strain with CVD for middle-aged and older men and women, but other age-related marital contexts (e.g., collaboration among older couples) may also contribute to this mechanism.

The present study examined the association of cardiac autonomic task-induced reactivity and recovery to preclinical atherosclerosis. Thirty-three men and 33 women aged 24-39 years participated in the ongoing epidemiological Cardiovascular Risk in Young Finns study. The authors measured heart rate (HR), respiratory sinus arrhythmia (RSA), and preejection period (PEP) during the mental arithmetic and speech tasks in 1999. Carotid atherosclerosis was assessed by measuring the thickness of the common carotid artery intima-media complex (IMT) with ultrasound in 2001. Higher HR, RSA, and PEP reactivity were associated with lower IMT values even after adjusting for cardiovascular risk factors (lipid levels, obesity, and blood pressure). In addition, better HR recovery after the mental arithmetic task was associated with lower IMT values, and this association persisted after all adjustments. Thus, higher task-induced cardiac autonomic reactivity and better HR recovery were related to less preclinical atherosclerosis. The authors concluded that cardiac pattern of reactivity and quick recovery may be associated with better cardiovascular health, and therefore all reactivity occurring in challenging situations should not automatically be considered as potentially pathological.

Although it is one of the most widely researched personality correlates of psychological reactions, the relationship between negative affectivity (NA) and physiological arousal has received little attention. This study examined the associations between NA and physiological outcomes of heart rate, skin temperature, and muscle tension. The authors hypothesized that when individuals are in a stressful situation, persons high in NA experience more heightened physiological arousal than those low in NA. After personality and demographic data were collected, 230 individuals participated in a stressful intervention. Individuals high in NA experienced a significantly greater rate of increase in electromyogram during the stress intervention and a lesser rate of decrease in electromyogram after the stressful event than those low in NA. In regard to skin temperature, those high in NA did not recover from the stress intervention as well as those low in NA. Negative affectivity was not related to heart rate.

Appraising negative experiences in ways that reduce associated distress is a key component of successful emotion regulation. In 4 studies, the authors examined the effects of systematically practicing appraisal skills using a computer-mediated cognitive bias modification (CBM) methodology. In Studies 1-3, healthy participants practiced applying appraisal themes linked to the idea of seeing the bigger picture to a series of distressing training films, either during each film (Study 1) or immediately after each film (Studies 2 and 3). Control participants watched the same films with no appraisal instructions. Participants who practiced appraisal, compared with controls, exhibited reduced levels of self-reported negative emotional (Studies 1-3) and electrodermal (Study 1) responses to a final test film that all participants were instructed to appraise. In Study 4, a comparable effect of appraisal practice was found using distressing autobiographical memories for participants with higher levels of negative affect. Appraisal practice also led to reduced intrusion and avoidance of the target memories in the week poststudy, compared with prestudy levels, and relative to the no-practice controls. The findings are discussed in terms of the broader literature on CBM. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

The study begins with the proposition that the individual's mode of coping with anxiety and his ability to resist and overcome the interference of anxiety in cognitive functioning are important determinants of performance under stress. It was decided to employ output or speed of performance as a measure of changes in motivation, and errors as a measure of interference. A suitable instrument that combined both measures was at hand in the Minnesota Clerical Test (MCT; Andrew & Paterson, 1946). This is a test of speed and accuracy which involves the scanning of pairs of numbers and of names and the detection of minor differences between the members of a pair. Subjects (65 student nurses) were divided into goal oriented and ego oriented groups and subdivided into high and low interference prone groups. Various aspects of performance on a cognitive task preceding and following failure in a situation in which they were motivated to succeed were compared. The results supported the hypotheses (a) that the goal oriented subjects increase output significantly following failure, whereas the ego oriented subjects do not, and (b) that the high interference prone subjects make more errors after failure than before, whereas the low interference prone subjects do not. Some of the implications of these results for the general problem of individual differences in performance under stress were discussed.
