The study examined physical symptoms and health service utilization of subjects high or low on a measure of the tendency to experience stress somatically and high or low on a measure of current stress. High somatic responders reported greater numbers of symptoms than low somatic responders regardless of stress level. However, high somatic responders who were experiencing high levels of current stress reported significantly more symptoms than high somatic responders who were experiencing low levels of stress. These findings indicate that somatic response to stress reflects both a general tendency to focus on physical symptoms, and a specific tendency to focus more on physical symptoms when under stress. Analysis of health service records indicated that high somatic responders had more visits prompted by symptoms than low somatic responders, but did not differ in frequency of health service visits designed to maintain health. The findings further clarify the relationship between somatic response to stress, physical symptoms and health service use.  相似文献

This study examined the vulnerability of the Michigan Alcoholism Screening Test (MAST), a widely used, direct alcohol inventory, to positive dissimulation. An earlier study by developers of the MAST suggested that most alcoholics were unable to alter their scores and thereby avoid detection by the instrument. But closer examination indicated that a standard scoring procedure was not employed. This study examined the ability of alcoholics to avoid detection by the MAST when using a standard scoring procedure. As predicted, alcoholics readily manipulated their MAST scores and avoided detection when so motivated. These results are discussed, indications and contraindications for use are included, and recommendations regarding future research are made.  相似文献

In this study, we examined factors associated with relapse and maintenance following a self-management training course. Thirty-five community professionals participated in a 3-week (30-hr) graduate-level extension course in self-management, which included a self-modification project. Results at a 10-week follow-up showed that end-of-class self-efficacy and outcome expectancy correctly classified over 80% of those who maintained gains in their projects versus those who relapsed. The professionals in the relapsed group also reported significantly more difficulty with anticipated high-risk situations than did those in the maintenance group.  相似文献

Remembering Your Parents: Reflections on the Retrospective Method   总被引:1,自引:0,他引:1  
In the present paper, I critique the use of the retrospective method when it is used as a proxy for actual longitudinal data on personality development. Studies on the constructive nature of memory cast strong doubts about the meaning of retrospective data. There are good reasons, both theoretical and empirical, to distrust the accuracy of such recall concerning parenting, whether recalled by parents, children, or siblings. Instead of using the method as a shortcut to developmental data, studies examining individual differences in accuracy and distortion and the factors that moderate them may inform us of the various meanings of retrospective data.  相似文献

ABSTRACT Progress in psychobiography What is it? Has there been any? And what processes contnbute to it? The issue of progress in psychobiography is pursued from two different perspectives The first section briefly reviews the historical growth of the field, including the range of disciplines involved, the rise of associated professional organizations and publication outlets, and a quantitative analysis of the increase in books, articles, and dissertations in psychobiography The second section argues that progress in psychobiographical understanding can be analyzed into eight component processes, such as the collection of additional evidence, the formulation of fresh interpretations, critical examination of prior explanations, and the application of new theoretical advances These processes are illustrated with an examination of the course of debate about the physical and psychological disturbances of King George III Personality psychology is concerned with the four basic tasks of developing general theories of personality, analyzing individual and group differences, understanding individual persons, and studying selected processes and classes of behavior In that developing a better understanding of individual persons is one of the ultimate objectives of personality psychology, progress in psychobiography is intimately related to progress in personality psychology as a whole  相似文献

This research tested the hypothesis that children's perceptions of academic competence and their personal control over school-related performance affects subsequent intrinsic interest and preference for challenge in an evaluative setting. In a correlational study, children's self-reported perceptions of academic competence and personal control were found to relate positively to their intrinsic interest in schoolwork and preference for challenging school activities. A subset of this sample was exposed to varying levels of a controlling directive, and preference for challenge was assessed behaviorally during a free-choice period in which subjects were unaware that they were being observed. As predicted, the data indicated that when given the evaluative, controlling directive, children who had high perceptions of academic competence and control preferred a greater challenge than did children whose perceptions were low on these measures. No difference between groups in terms of preference for challenge was evident when no controlling directive was presented. These findings are discussed in terms of theories of intrinsic motivation and potential processes that underly these effects.  相似文献

Two studies, with undergraduate subjects, investigated how sex and situation-specific power factors relate to visual behavior in mixed-sex interactions. The power variable in Study 1 was expert power, based on differential knowledge. Mixed-sex dyads were formed such that members had complementary areas of expertise. In Study 2, reward power was manipulated. Consistent with expectation states theory, both men and women high in expertise or reward power displayed high visual dominance, defined as the ratio of looking while speaking to looking while listening. Specifically, men and women high in expertise or reward power exhibited equivalent levels of looking while speaking and looking while listening. High visual dominance ratios have been associated with high social power in previous research. Both men and women low in expertise or reward power looked more while listening than while speaking, producing a relatively low visual dominance ratio. In conditions in which men and women did not possess differential expertise or reward power, visual behavior was related to sex. Men displayed visual behavior similar to their patterns in the high expertise and high reward power conditions, whereas women exhibited visual behavior similar to their patterns in the low expertise and low reward power conditions. The results demonstrate how social expectations are reflected in nonverbal power displays.  相似文献

We interviewed spinal-cord-injured, other handicapped, and nonhandicapped subjects to investigate the relation between the perception of autonomic arousal and experienced emotion. The three groups differed significantly on only one measure of affect intensity, with the spinal-cord-injured subjects more often reporting stronger fear in their lives now compared with the past. In addition, spinal-cord-injured subjects often described intense emotional experiences. Spinal-cord-injured subjects who differed in their level of autonomic feedback differed in intensity on several measures. Subjects with greater autonomic feedback tended to report more intense levels of negative emotions. The findings indicate that the perception of autonomic arousal may not be necessary for emotional experience. There were weak trends in our data, however, suggesting that the perception of arousal may enhance the experience of emotional intensity. The subjective well-being reports of the handicapped groups were comparable to those of nonhandicapped subjects, indicating successful coping with their disability.  相似文献

The present study is concerned with the perceptual information about the body and space underlying the act of catching a ball. In a series of four experiments, subjects were asked to catch a luminous ball under various visual conditions. In general, catching in a normally illuminated room was contrasted with catching the luminous ball in an otherwise completely dark room. In the third and fourth experiments, intermediate conditions of visual information were included. The results suggest that it is possible to catch a ball with one hand when only the ball is visible, but performance is better when the subject has the benefit of a rich visual environment and two hands. The second experiment indicated that subject performance does improve with practice in the dark, but time spent in the darkened room itself doesn't result in a significant decrement in performance. Results of the third study suggest that vision of one's hand does not aid in the performance of this task whereas the presence of a minimal visual frame appears to aid performance. The final study examined the relation between catching performance and body sway under similar visual conditions. Results of this experiment imply that persons who exhibit relatively little postural sway in full-room lighting performed better at this catching task.  相似文献
