Previous research has suggested that women with a negative emotional orientation toward sexuality (i.e., erotophobia) have difficulty learning and retaining sexually relevant material such as contraceptive information. It has been hypothesized that these women become aroused by this material and that this arousal interferes with their ability to learn it. The importance of this issue led us to conduct the current study. Erotophobic and erotophilic women viewed presentations about contraception while their physiological responses were being monitored. In addition, they were tested on the information contained in the presentation before, immediately after, and again 4-6 weeks after the presentation. The results indicated that the erotophobic women knew less contraceptive information before the presentation and were more aroused by the presentation. This arousal, however, did not interfere with retention of the material. These results are discussed in terms of individual differences in reactions to sexual material and the ability to learn, retain, and use contraceptive information.  相似文献

We studied the correlation of one measure of imagery ability, the Visual Elaboration Scale, with two others, absorption of image and effort required to form a mental image. Significant correlations were obtained between the Visual Elaboration Scale and the other scales, with the exception of Absorption for women.  相似文献

Ratings of pre-morbid intelligence level, derived from the hospital charts of 26 chronic schizophrenics, were correlated with the post-mortem brain volume measures of cortex, white matter, central grey matter, and ventricles. Contrary to hypothesis, no significant correlations were found.  相似文献

INDIVIDUAL AND SITUATIONAL CORRELATES OF WHISTLE-BLOWING   总被引:5,自引:0,他引:5  
Although popular interest in whistle-blowing continues to increase, little is known about why some employees who observe wrongdoing report it, while others do not. In the present study, we analyze archival survey data from individuals who observed wrongdoing in any of 22 organizations. Results are generally consistent with predictions based on a model of whistle-blowing as a type of prosocial behavior. Whistle-blowing was more likely when observers of wrongdoing (1) held professional positions, (2) had more positive reactions to their work, (3) had longer service, (4) were recently recognized for good performance, (5) were male (though race was unrelated to whistle-blowing), (6) were members of larger work groups, and (7) were employed by organizations perceived by others to be responsive to complaints. Implications for research and practice are described.  相似文献

INFLUENCES ON MANAGERIAL PAY ALLOCATIONS: A DEPENDENCY PERSPECTIVE   总被引:1,自引:0,他引:1  
This paper reviews evidence and presents arguments for the view that managerial pay allocations are influenced by the degree of dependence on subordinates and by threats to that dependence. In assessing this view, the issues of managerial discretion in pay allocation and pay as a means of managing dependencies are explored. Major sources of objective and subjective dependence on subordinates are identified. Predictions are made regarding managerial pay allocations under various conditions of dependence and dependency threat. Finally, research and practical implications of the dependency perspective are discussed.  相似文献
