Previous experimental investigation of the effects of repeating an unfamiliar stimulus suggests that mere exposure breeds attraction (e.g., Zajonc, 1968). On the other hand, correlational work with naturally occurring stimuli such as names, music, or landscapes suggests that there is also an overexposure effect: the preference function does rise with familiarity at first but then reaches a turning point and diminishes. The study (N=72) demonstrates this inverted-U relationship in an experimental setting. The stimuli were synthetic nonsense speech, permitting exact control of exposure durations and interstimulus intervals. The critical factors for demonstrating the effect are probably (1) the inclusion of a large number of repetitions, and (2) blocked repetition of each stimulus in a homogeneous sequence not interspersed with other more or less frequent stimuli.  相似文献

Testicular self-examination (TSE) can lead to early diagnosis and treatment of testicular cancer, the third leading cause of death in young men. We evaluated the effectiveness of a brief and specific checklist for teaching TSE skills. Ten men were videotaped while performing testicular self-examinations before and after training. The TSE training resulted in large and significant increases in the number of TSE steps completed and duration of the TSE. Two urological validation measures supported the improvements observed in the mens' self-examinations. Subjects reported continued performance of TSE during a follow-up telephone interview. This pilot study indicates that a brief and specific checklist is an effective strategy for teaching early cancer detection skills.  相似文献

The purpose of this paper is to examine the usefulness of factor analysis in developing and evaluating personality scales that measure limited domain constructs The approach advocated follows from several assumptions that a single scale ought to measure a single construct, that factor analysis ought to be applied routinely to new personality scales, and that the factors of a scale are important if it can be demonstrated that they are differentially related to other measures A detailed study of the Self-Monitoring Scale illustrates how factor analysis can help us to understand what a scale measures A second example uses the self-esteem literature to illustrate how factor analysis can clarify the proliferation of scales within a single content domain Both examples show how factor analysis can be used to identify important conceptual distinctions Confirmatory techniques are also introduced as a means for testing specific hypotheses It is concluded that factor analysis can make an important contribution to programmatic research in personality psychology  相似文献

There are very few women who take up careers as engineers - especially at the non-professional level. The present research attempts to throw some light on this issue, examining by means of a postal questionnaire the educational experiences of 22 young women craft and technician apprentices in a variety of engineering jobs. Comparisons are made with 33 similar young women who have chosen more traditional 'female' occupations. The results show significant differences between engineers and non-engineers in terms of their subject choices and curriculum opportunities at school and their perceptions of the attitudes of parents to wards their careers. Possible implications of the findings for developments in curriculum planning and careers guidance are explored.  相似文献

The present research studied self-awareness by utilizing experiential sampling methodology, which allows for the random sampling of individuals' thoughts and feelings as they go about their normal daily activities. Neither Study 1 nor 2 found a relation between private or public self-awareness and negative affect. However, attention to private self-aspects was generally more positive and less ruminative for low as opposed to high private self-conscious subjects, and awareness of oneself as a social object was generally more positive but less important for low as opposed to high public self-conscious subjects. What may have accounted for the negative relation between private self-consciousness and average affect was that low private self-conscious subjects were more likely to attend to their private self-aspects if they were pleasant than if they were unpleasant, while high private self-conscious subjects' degree of private self-awareness was unrelated to whether the content of this state was pleasant or not. These findings are consistent with the hypothesis that low private self-conscious individuals engage in a more selective type of self-attention when in the private self-aware state than do high private self-conscious individuals. Regarding the relation between self-awareness and social context, both studies found that the presence of others results in a heightened public self-awareness. However, even though subjects were more attentive to public self-aspects when with others than when alone, in general, they were more attentive to their “private self” than to their “public self”. Results are discussed in terms of current self-awareness theory.  相似文献

One hundred and forty-four male and female Australian subjects rated an Australian or a Vietnamese target group on the possession of five socially desirable and five socially undesirable personality traits. As predicted, the out-group was perceived less favourably than the in-group, but only by the males, the females not making the distinction.  相似文献

The study sought to determine whether current nursing graduates value assertiveness, independence, and achievement to a greater degree than had past graduates, and whether selection or socialization might account for such a change. Scores on the Allport Vernon Lindsey Scale of Values for 55 1974 graduates of a private baccalaureate school of nursing were compared with 66 1980 graduates. Only scores on the political scale were significantly higher for the 1980 class. 1980 graduates displayed a traditional value pattern of high social and low political scores upon entering the educational program. Longitudinal comparison of scores for the 1980 class showed a significant rise in scores on the political scale; graduating scores did not differ significantly from college norms. The results suggest a rise in nontraditional values which is the result of the educational socialization process.  相似文献
