There appears to be a strong relationship between mass media portrayals of violence and real-life violence itself. This article reviews the available literature on the effects of media treatment of sports violence; analyzes the theoretical explanations for this treatment; and makes proposals on how the problems of both sports violence and its media coverage may be remedied, with a particular focus on amateur hockey in Canada.  相似文献

This study examines the relationship between performance on a context-independent fault diagnosis task and two dimensions of cognitive style: field dependence/independence (D-I) and focusing/scanning (F-S). The effects on diagnosis performance of training and the ability of both dimensions of style jointly to predict fault-finding ability were considered. The results showed that field independents and focusers were superior fault diagnosticians. Training, in the form of verbal feedback messages, was uniformly effective for the D-I dimension although field independents maintained a superior level of performance, over field dependents. In general, for the F-S dimension, training had little effect on either the focusers or scanners. A combination of scores on the F-S and D-I dimensions significantly enhanced the proportion of the variance in testing efficiency that could be accounted for during fault-finding. Finally it is argued that the F-S and D-I dimensions should be recognized as measures of ability, not style. Future research should be directed at identifying between subject differences on fault diagnosis tasks with reference to theories of information processing.  相似文献

This study explored the effectiveness, in terms of age of the client, of a 10-week cognitive-behavioral group therapy (stress inoculation training) for chronic pain. A total of 69 outpatients between the ages of 27 and 80 (M = 52.74 years, SD = 14.40) with diverse types of chronic pain were assigned randomly to immediate or wait-list-delayed therapy. Self-report measures of pain, activities, coping, and the use of medications and other physical pain control techniques were obtained at baseline, during therapy, and at 1- and 6-month follow-up. Treatment decreased the degree to which pain interfered with activity, increased ability to cope with pain, and decreased use of some medications and other physical treatments. It had little effect on perceived pain intensity. Gains were maintained through 6-month follow-up. Age was unrelated to outcome. Stress inoculation training appears to be an effective method of ameliorating the interference of chronic pain with the daily activities of life for adults of all ages.  相似文献

Although stress and anxiety have long been assumed to play an exacerbatory role in asthma, no study has systematically documented that daily exacerbations of asthma symptoms are related to stress and/or anxiety. In this study, 24 airways obstruction patients (12 asthmatics and 12 chronic obstructive pulmonary disease patients) were instructed to monitor the severity of daily respiratory symptoms. In addition, subjects recorded their daily anxiety level and the number and perceived impact of daily stressors. The results showed that although there were differences between high- and low-stress days for both groups, there were no differences between groups on symptom severity or between high- and low-anxiety days, as measured by the State-Trait Anxiety Inventory (STAI). Thus, although the number and impact of daily stressors were found to be directly associated with the severity of asthma symptoms, anxiety does not appear to have a direct role in the exacerbation of asthma. The findings failed to support the anxiety theory of asthma but provided an explanation for the poor results obtained in previous treatment studies which employed anxiety management with asthmatics.  相似文献

Two multidimensional mood-state inventories, the Profile of Mood States (POMS) and the Eight State Questionnaire (8SQ), were administered to 289 Australian college undergraduates. Intercorrelations for the combined 14 subscales were subjected to a higher-order factor analysis in order to elucidate the central clinical states within the mood-state sphere. Results suggested four major state dimensions pertaining to Neuroticism, Hostility/Anger, Vigor, and a combined Extroversion/Arousal-Fatigue entity. Both three- and five-factor solutions were taken out for comparative purposes. Furthermore, separate higher-order factorings of the POMS on normative samples of 350 male and 650 female psychiatric outpatients were conducted, corroborating three of the four central state dimensions, at least in the case of females. The implications of these findings for behavioral assessment are discussed.This study was supported by a Research Development Grant awarded to the author by the University of Melbourne.  相似文献

The belief is widely held that humor is related to recovery from, and perhaps an increased resistance to, coronary and other stress-related diseases. Such generalizations do not typically distinguish between benign and hostile humor. In the present research, the relationship between a measure of proneness to coronary heart disease (CHD) and appreciation of hostile and nonhostile humor is examined. In two studies, one with college students and one with patients suffering from CHD, the relationship between humor preferences and the coronary-prone (Type A) behavior pattern was examined. Each subject was given the Jenkins Activity Survey as a measure of the coronary-prone personality type, and aggressive and nonaggressive jokes to rate for funniness. Hostile humor was preferred to nonhostile humor by all groups, but among those suffering from CHD, those who could be classified as “Type B’s” preferred nonhostile humor. The results indicate that those less prone to CHD appreciate both hostile and nonhostile humor, while Type A’s seem to enjoy hostile humor only.  相似文献

This study investigated attitudes about body weight and appearance in a group of young adults. Undergraduate psychology students at the Flinders University of South Australia and at the University of Vermont were asked about their weight and dieting, consciousness about their body, the degree to which their weight had interfered with social activities, their perceptions about the causes of obseity, and their stereotypes about fat and thin men and women. Although 20% of the sample was overweight, 50% of subjects perceived themselves to be overweight to some degree. As expected, weight was a much greater issue for women, who felt more overweight, dieted more, expressed more body consciousness, and reported that weight had interfered more with social activities than did men. Also as expected, Vermont students reported greater frequency of dieting, more concern about weight, and more body consciousness than did students in Australia. Finally, men and women in both cultures stereotyped obese targets significantly more negatively than they did nonobese targets. The results indicate excessive and maladaptive concerns with weight in general, and among women and U.S. students in particular.  相似文献

A synthesis of cultural materialism and behavior analysis might increase the scientific and technological value of both fields. Conceptual and substantive relations between the two fields show important similarities, particularly with regard to the causal role of the environment in behavioral and cultural evolution. Key concepts in Marvin Harris's cultural materialist theories are outlined. A distinction is made between contingencies at the behavioral level of analysis (contingencies of reinforcement) and contingencies at the cultural level of analysis (metacontingencies). Relations between the two kinds of contingencies are explored in cultural practices from paleolithic to industrial sociocultural systems. A synthesis of these two fields may offer the opportunity to resolve serious problems currently facing modern cultures.  相似文献

A stratified random sample of college student affairs divisions was surveyed to assess the depth and breadth of student paraprofessional use. More than 72% of the responding institutions reported having one or more student paraprofessional programs.  相似文献
