Stages of career development consistent with age were found in a group of employed managers and professionals. They tended to attribute career success to inherent abilities, education, and developmental experiences in the company studied. Trends among three age groups were similar in regard to factors they perceived as enhancing or adversely affecting their career development.  相似文献

Self-report and physiologic measures of arousal were obtained during in vivo flooding sessions. Minimal correspondence was found between these two assessment modalities. The significance of these findings for treatment is discussed.  相似文献

Married couples seeking sex therapy, marital therapy, or no form of therapy were compared with respect to personality, sexual and marital functioning. The Sexual Dysfunction and Marital Difficulties groups (15 and 10 couples respectively) were obtained from the waiting lists of a sexual dysfunction service and marital therapy unit. Non-Problem subjects (15 couples) were from a volunteer sample. Personal adjustment, sexual and marital functioning were assessed by means of the Eysenck Personality Inventory, a Sexual Behavior Questionnaire, the Locke-Wallace Marital Adjustment Survey, and the Azrin Marital Happiness Scale. Results indicated that although all three groups were within the normal range, problem couples had higher ‘neuroticism’ scores than did Non-Problem couples. Marital Problem couples were the most debilitated. Their marital adjustment was lowest, and their sexual functioning was comparable to the Sexual Dysfunction group. Marital adjustment of the Sexual Dysfunction couples was significantly higher than that of the Marital Difficulties couples. Therapeutic and theoretical implications of the differentiating characteristics in the three couple categories are discussed.  相似文献

In a study designed to test Patterson's arousal model of nonverbal intimacy, the heartrate, gaze, smiles, body orientation, and body lean of each of 40 female subjects who interacted with an accomplice were measured. Within a factorial design, subjects were induced to view more or less favorably the accomplice, who subsequently increased or maintained the same level of nonverbal immediacy as she did in an earlier session. It was hypothesized that (1) an increase in the accomplice's immediacy would effect an increase in subjects' arousal (heartrate) which, in turn, (2) would lead to either reciprocal or compensatory nonverbal adjustments by subjects, depending on whether they viewed the accomplice more or less favorably, respectively. The results supported the first but not the second hypothesis. However, interpretation of the results suggests, nevertheless, that they may be consistent with the arousal model.  相似文献

Most psychological tests and inventories, particularly in personality and attitude measurement, contain common items, that is, various subscales of the test or inventory may share one or more items in common. Surprisingly, the role of common items in such a fundamental personality test attribute as reliability is not known. The present report specifically considered common-item contributions to test internal consistency reliability using extant data from the California Psychological Inventory. No negative contribution of item overlap was found. To the contrary, it was concluded that the use of common items is an economical technique for increasing the total number of items in the scales, thus increasing scale internal reliabilities without increasing the overall number of items in the inventory.  相似文献

Two randomly assigned groups, N = 7 each, of neurologically normal patients were composed. One group, RM, had regional cerebral blood flow measurements during a recognition memory probe test; the other group, SC, had rCBF measurements during a semantic classification task, using the same stimulus and response features as the RM task. Thus, the groups differed only in the cognitive instruction they were executing. The RM group showed a significantly lower change from resting baseline to activation, in mean left hemisphere initial slope index, than did the SC group. The RM group, but not the SC group, showed a significant inverse correlation between occipital flow and accuracy of memory performance as indicated by d′. Correlations between age and hemispheric initial slope index, and between homologous left and right hemisphere sites, were also described. The results are considered to support an anatomical basis for the distinction between episodic and semantic memory and to suggest that occipital flow may diminish with accurate memory performance because of an upstream demand of blood in the medial temporal lobes.  相似文献

An information processing system for a psychiatric emergency room is described. Several studies are presented that show the utility of the system. In the first study, variables involved in diagnosis are explicated. The second study attempts to determine the characteristics that distinguish recidivists from nonrecidivists at an emergency room. The third study attempts to find patient variables related to success in short-term treatment programs. The final study is aimed at discovering whether there are psychopathological effects related to the use of inhalants. Together, these studies show the potential of a mental health information system for learning more about the nature of mental disorders and their treatment.  相似文献
