The present investigation sought to further delineate the Type A coronary-prone behavior pattern and to elucidate the psychophysiological process through which this behavioral disposition is translated into heart disease. Type A and Type B male subjects engaged in tasks that required varying degrees of activity before an assessment of challenge-seeking tendencies. Type A participants sought greater degrees of challenge than did their Type B counterparts. In addition, the more active the person with Pattern A had been immediately before the challenge-seeking opportunity, the greater the degree of challenge sought. Precedent activity level did not significantly influence challenge seeking in the Type B population. The Type A subjects also had significantly faster heart rates during performance of a challenging task. Pattern A behavior may be translated into heart disease through the cumulative deleterious effects of chronic and excessive challenge-induced cardiovascular excitation. 相似文献

MMPI profiles of 442 male narcotic addicts in a drug treatment program were classified according to one of three methods: (a) highest 2-point code, (b) cluster analysis, and (c) concordance with common actuarial rules of profile fit. Profiles were then compared with those previously reported in the research literature. While each method resulted in slightly different perspectives, each reported modal profiles analogous to the 49'/94', 42'/24', and 48'/84' profiles. A frequency table of 33 different profiles by rates per thousand were presented as prototypal base rates for future comparison. 相似文献

This article is intended to provide counselors with an overview of narcissism and its treatment. In the first section, dysfunctional narcissism is described, drawing on the diagnostic indicators presented in the DSM-III and the contemporary object relations theories of Heinz Kohut and Otto Kernberg. The second section focuses on counseling narcissistic clients. 相似文献

The idealized physique preferences of a group of 94 male college students were measured and correlated with scales measuring attitudes toward women and personality rigidity. Three hypotheses, derived from sex-role research, were tested and confirmed: (1) Males who have negative attitudes toward women would like most to have a tapering V physique. (2) Males who have a rigid personality structure have stronger preference for an idealized muscular physique than males with more flexible personalities. (3) Males have a generally greater preference for a tapering V physique than women. It was concluded, from the results of this and other studies, that body preference is related to certain aspects of sex-role attitudes. 相似文献

Process and content issues were evaluated during the first six months of an outpatient schizophrenic group. Compared with groups composed of neurotic and characterological patients, the schizophrenic group scored higher in the Avoiding dimension of the Group Climate Questionnaire (GCQ-S). There was more cohesion and less interpersonal conflict as time went on. Although topics related to engagement and differentiation were discussed, there was no obvious GCQ-S evidence of these first two stages of group development. However, the data supported the presence of stage 3 (individuation) during sessions 20–26. Interpersonal topics dominated the group discussions, followed by issues involving reality-testing, expression of emotions, and advice-giving.The authors wish to thank Dr. K. Roy MacKenzie for his helpful comments on a draft of this paper. 相似文献

幼儿不同情绪状态对其智力操作的影响 总被引:3,自引:1,他引:2
本实验结果显示:1)在16至18个月的婴儿中,愉快和痛苦情绪对其问题解决的操作有不同的影响。愉快组被试比痛苦组被试的操作效果明显优越;体现在“直接抓取”、“注视”和“顺利获得”三种操作策略中。2)愉快和痛苦两种情绪的不同强度与操作效果之间的相关是不同的。愉快组显示为一种曲线相关,即过高或过低的情绪唤醒不如适中的唤醒水平使操作效果达到最优。痛苦组显示为一种直线相关,即痛苦强度越大,操作效果越差。 相似文献

Previous reports of age-of-acquisition effects have been theoretically ambiguous since, in any particular individual, word
age-of-acquisition is perfectly correlated with the length of time that a word has been known. The study reported in this
article attempted to disentangle effects of word age-of-acquisition and length of word residence time in lexical memory. To
this end, words varying in recency-of-introduction to British English were presented in a word-naming task to 46 native speakers
whose ages ranged from 20 to 58 years. Using subjects’ ratings of the words on age-of-acquisition, it was possible to assess
word residence times and to compare the effects on naming speeds of age-of-acquisition and residence times. Regression analyses
indicated that age-of-acquisition was a more important factor than residence time in the word-naming task. 相似文献
