Effect of levels of exercise on psychological mood states, physical fitness, and plasma beta-endorphin 总被引:1,自引:0,他引:1
Aerobic exercise which resulted in a significant improvement in cardiovascular functioning had no more effect on psychological mood states than did the placebo control of participation in nonaerobic recreational games or no exercise and sport at all (N = 430 college students). Beta-endorphin levels with the 41 depressed subjects were not a biochemical link that might explain the possible influence of physical activity on depression. 相似文献

In the kibbutz today, there are no ideological or economic barriers to prevent a couple from deciding to divorce. Both husband and wife are assured continued economic security and equal opportunities for co-parenting, thus reducing fears of disruption in the daily contact with the children. In spite of these favorable circumstances, marital breakups in the kibbutz are less frequent than in the larger cities in Israel. In recent years, however, at a time when a stronger and more intensive family life has gained legitimacy within the kibbutz structure, there is a marked tendency toward a rise in the rate of divorce. In this article we analyze the possible causes of the variations in the frequency of divorce within the kibbutz framework.The authors express appreciation to Esther Mivtzari, a psychologist on the staff of the Kibbutz Child and Family Clinic and a member of the religious kibbutz Ein-Tzurim, for assistance in gathering data on divorce in the religious kibbitzum. 相似文献

This study focuses on Divorce-Prone individuals and the question of why some persons fail in one marriage after another. The authors studied 12 individuals who had each been divorced two or more times. They found that the cases fell into one of three broad and overlapping groups. The groups have been called the Self-Involved Narcissists, the Compliant Depressed, and the Casualties of Life's Vicissitudes. The individuals and the groups demonstrate a different etiology, different treatment problems, and a very different prognosis. 相似文献

This paper considers the status of family intervention as an area of interest defined by its literature (70 publications) and includes a brief history, assessment of present status, and recommendations for future development of family crisis intervention as a distinct field with concepts and goals that can be clearly defined, taught, researched, and repeated in treatment. Recommendations are made for the development of an explicit paradigm for intervention with a clear, common language of terms and concepts for family involvement. Suggested directions for developing the paradigm and language are explored. 相似文献

In this study of 37 pre-therapy and 23 matched control families who never sought family therapy, father-child welfare affect and mother-child emergency affect were significantly higher in the control families. Control families were found generally to express more Welfare and Emergency emotion. Affective expression between parents did not significantly differentiate the groups.This study has been supported by Grant No. MA-4510 of the Medical Research Council of Canada and was presented at the annual meeting of the Canadian Psychiatric Association, Ottawa, Ontario, Canada, September 1983. The authors wish to express their thanks to Toby Schwartz, Harriet Gold-Kaats, and Terry Tannenbaum-Dascal, who acted as coders and research assistants; Joseph Beltempo, BSc, who helped in the statistical analysis; and James Robbins, PhD, who gave much valuable advice. 相似文献

An experiment which employed each of 18 subjects in four days of testing was used to examine acute secobarbital dose treatment effects on choice reaction time in a Cooper and Shepard (1973) character recognition task. Manipulations of visual stimulus degradation, character difficulty, 180 degree rotation, and mirror-image reversal were included in order to evaluate the hypothesis that the drug affects performance by disrupting early stimulus input processing. The results indicate significant increases in the effect of secobarbital on reaction time and errors under conditions of visual stimulus degradation. The effects of the drug, however, were not changed by 180 degree rotation of the target character or by the other task variables. The results were interpreted to indicate that secobarbital impairs performance primarily by placing selective stress on hypothetical early encoding activities and that later processing operations (associated with use of an internal representation of the target character) are not affected by the drug. Strengths and weaknesses of the two-stage model of visual stimulus processing are discussed and implications of the model for future drug research are indicated. 相似文献

Awareness of the response after feedback training for changes in heart rate and sudomotor laterality
L E Roberts R J Williams R G Marlin T Farrell D Imiolo 《Journal of experimental psychology. General》1984,113(2):225-255
What is the relation between the ability to control visceral responding on a biofeedback task and the ability to report behaviors actually contributing to this performance? Subjects received biofeedback training for unidentified visceral responses and then gave written reports about what they had done to control the feedback displays. Independent judges were given these reports and, on the basis of knowledge about activities known to contribute to visceral activity, were asked to determine the visceral responses for which the subjects had been trained. The reports of subjects who succeeded at bidirectional control of heart rate (Experiment 1) or sudomotor laterality (Experiment 2) showed awareness of behaviors related to feedback as assessed by this procedure, whereas the reports of subjects who failed at bidirectional control did not. Subsequent experiments indicated that these results did not depend on a learning strategy that might have been specific to the initial studies. These findings call into question the view that people are unaware of what they have done to produce the response after training on biofeedback tasks. Earlier studies reporting lack of awareness in biofeedback are discussed in light of factors that affect the measurement of biofeedback learning and response awareness. 相似文献

We investigated the programming of generalization and maintenance of correspondence between verbal and nonverbal behavior in a preschool setting. Four children participated in a series of multiple-baseline designs. In Experiment 1, delayed reinforcement of verbal behavior effectively controlled maintenance of correspondence with previously trained responses and also resulted in generalization of correspondence to one untrained response. As the latter effect was limited, Experiment 2 was a further assessment of the effects of delayed reinforcement of generalization of correspondence to untrained responses, and consistent generalization was shown. Experiment 2 also showed that generalization, if lost, could be recovered through use of "booster training," in which the original contingencies were reinstated for a brief period. Experiment 3 provided replications, with two additional children, of the effects of delayed reinforcement on maintenance of correspondence. Results are discussed in terms of using delayed reinforcement as an indiscriminable contingency. 相似文献

We can use radically different reference-schemes to generate the same truth-conditions for the sentences of a language. In this paper, we do three things. (1) Distinguish two arguments that deploy this observation to derive different conclusions. The first argues that reference is radically indeterminate: there is no fact of the matter what ordinary terms refer to. This threat is taken seriously and most contemporary metasemantic theories come with resources intended to rebut it. The second argues for radical parochialism about reference: it's a reflection of our parochial interests, rather than the nature of the subject matter, that our theorizing about language appeals to reference rather than another relation that generates the same truth-conditions. Rebuttals of the first argument cut no ice against the second, because radical parochialism is compatible with reference being determinate. (2) Argue that radical parochialism, like radical indeterminacy, would be shocking if true. (3) Argue that the case for radical parochialism turns on the explanatory purposes of “reference”-talk: on relatively “thin” conceptions, the argument goes through, and radical parochialism is (shockingly!) true; on richer conceptions, the argument can be blocked. We conclude that non-revisionists must endorse, and justify, a relatively rich conception of the explanatory purposes of “reference”-talk. 相似文献
