Over-claiming is a concrete operalization of self-enhancement based on respondents' ratings of their knowledge of various persons, events, products, and so on. Because 20% of the items are nonexistent, responses can be analyzed with signal detection formulas to index both response bias (over-claiming) and accuracy (knowledge). Study 1 demonstrated convergence of over-claiming with alternative measures of self-enhancement but independence from cognitive ability. In Studies 2-3, the validity of the over-claiming index held even when respondents were (a) warned about the foils or (b) asked to fake good. Study 3 also showed the utility of the over-claiming index for diagnosing faking. In Study 4, the over-claiming technique was applied to the debate over the adaptive value of positive illusions.

心理健康标准一般有三种依据:医学标准、社会标准、统计学标准。一个完整的心理健康标准的制定,应该既考察适应状况,又能考察发展状况。从教育的社会价值及个人价值,特别是我国特有的教育文化背景来看,更应给发展标准以更多的关注。  相似文献

This study investigated the relationships among previous experiences of student alienation and the various aspects of self concept. A total of 351 undergraduate students were administered the Student Alienation and Trauma Survey-Revised (SATS-R) and the Tennessee Self Concept Scale: Second Edition (TSCS:2). Students were asked to report on their worst experience in school, symptoms they had following this worst experience, and overall feelings about themselves. Results indicated a moderate negative correlation between self concept and student alienation. A stepwise multiple regression analysis indicated that among the subtests of the SATS-R, Hopelessness, and General Maladjustment scores best predicted poor student self concept.

Four experiments explored the effects of mating motivation on creativity. Even without other incentives to be creative, romantic motives enhanced creativity on subjective and objective measures. For men, any cue designed to activate a short-term or a long-term mating goal increased creative displays; however, women displayed more creativity only when primed to attract a high-quality long-term mate. These creative boosts were unrelated to increased effort on creative tasks or to changes in mood or arousal. Furthermore, results were unaffected by the application of monetary incentives for creativity. These findings align with the view that creative displays in both sexes may be linked to sexual selection, qualified by unique exigencies of human parental investment.

This article presents the integrative journey of a doctoral student across two continents. The development and aspirations of a student integrationist from the "get go" are outlined, and some thoughts on the future of the integration movement are offered. The role of self-direction, integrative role models, flexible training environments, and the support of the integrative community in one's integrative development are highlighted.

Reports an error in the original article by Walter G. Stephan and David Rosenfield (Journal of Personality and Social Psychology, 1978[Aug], Vol 36[8], pp. 795-804). Two corrections are needed to correlations in Table 2 on page 800. (The following abstract of this article originally appeared in record 1980-02037-001.) Examined the determinants of changes in the racial attitudes of 65 White elementary school children during school desegregation. A multiple regression analysis showed that increases in children's self-esteem, increases in children's interethnic contact, low parental authoritarianism, and nonpunitive parental child-rearing practices were all significantly related to positive changes in racial attitudes. In addition, data are presented that indicate that parental opposition to integration is an indirect determinant of change in children's racial attitudes because of its impact on children's interethnic contact.
