The present research reports the results of three studies showing that individuals with a fragile self‐concept in the domain of performance are particularly vulnerable to stereotype threat effects. Specifically, women who explicitly described themselves as rather mathematical but whose implicit self‐concepts contradicted these claims were vulnerable to stereotype threat effects on mathematical performance. This effect was robust across three studies, independent of the subtleness or content of the stereotype threat manipulation. Additionally, it was shown that the effect was mediated by anxious worrying (Study 3). Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

Early sexual debut is associated with risky sexual behavior and an increased risk of unplanned pregnancy and sexually transmitted infections later in life. The relations among early movie sexual exposure (MSE), sexual debut, and risky sexual behavior in adulthood (i.e., multiple sexual partners and inconsistent condom use) were examined in a longitudinal study of U.S. adolescents. MSE was measured using the Beach method, a comprehensive procedure for media content coding. Controlling for characteristics of adolescents and their families, analyses showed that MSE predicted age of sexual debut, both directly and indirectly through changes in sensation seeking. MSE also predicted engagement in risky sexual behaviors both directly and indirectly via early sexual debut. These results suggest that MSE may promote sexual risk taking both by modifying sexual behavior and by accelerating the normal rise in sensation seeking during adolescence. 相似文献

Objectives
In the sport context, the coach-athlete relationship has been viewed and studied as a universal phenomenon. It is thus important to assess the universality of the psychometric scale that is used to measure the quality of coach-athlete relationships. The present study examined the cultural equivalence or measurement invariance of the Coach-Athlete Relationship Questionnaire (11-item, athlete version CART-Q).Design
Cross-sectional study.Methods
A total of 1363 athletes from Belgium (N = 200), Britain (N = 382), China (N = 200), Greece (N = 115), Spain (N = 120), Sweden (N = 169), and United States of America (N = 177) completed the CART-Q.Results
Multi-group mean and covariance structure (MACS) analyses supported the factorial validity of the CART-Q in a three-first-order factor model across the seven countries. An examination of the latent mean differences of the CART-Q revealed some variation in terms of the intensity that athletes perceive in the quality of the relationship with their coach across the different countries.Conclusions
Overall, these results supply additional evidence of the psychometric properties of the CART-Q and highlight that it is a sound instrument that can be applied cross-culturally. 相似文献225.

The terror management health model (TMHM) suggests that when thoughts of death are accessible people become increasingly motivated to bolster their self-esteem relative to their health, because doing so offers psychological protection against mortality concerns. Two studies examined sun protection intentions as a function of mortality reminders and an appearance-based intervention. In Study 1, participants given a sun protection message that primed mortality and shown a UV-filtered photo of their face reported greater intentions to use sun protection on their face, and took more sunscreen samples than participants shown a regular photo of their face. In Study 2, reminders of mortality increased participants’ intentions to use facial sun protection when the UV photo was specifically framed as revealing appearance consequences of tanning, compared to when the photo was framed as revealing health consequences or when no photo was shown. These findings extend the TMHM, and provide preliminary evidence that appearance-based tanning interventions have a greater influence on sun protection intentions under conditions that prime thoughts of death. We discuss implications of the findings, and highlight the need for additional research examining the applicability to long-term tanning behaviour. 相似文献

Although African-Americans (Blacks) smoke fewer cigarettes per day than European-Americans (Whites), there is ample evidence that Blacks are more susceptible to smoking-related health consequences. A variety of behavioural, social and biological factors have been linked to this increased risk. There has been little research, however, on racial differences in smoking-related knowledge and perceived risk of lung cancer. The primary goal of the current study was to evaluate beliefs and knowledge that contribute to race disparities in lung cancer risk among current smokers. Data from two separate nationally representative surveys (the Health Information National Trends surveys 2003 and 2005) were analysed. Logistic and hierarchical regressions were conducted; gender, age, education level, annual household income and amount of smoking were included as covariates. In both studies, Black smokers were significantly more likely to endorse inaccurate statements than were White smokers, and did not estimate their lung cancer risk to be significantly higher than Whites. Results highlight an important racial disparity in public health knowledge among current smokers. 相似文献

Based on systematic surface observations, experimental measurements on the fatigue limits of differently oriented copper single crystals cyclically deformed at constant plastic strain amplitudes are summarized, and an orientation dependence of the fatigue limit is sketched. It was found that the fatigue limits of crystals depend mainly upon the low-strain-amplitude dislocation structures, which are characteristic of the particular crystal orientations. When multiple-slip deformation is the main mode of deformation and ultimately produces stable lowenergy dislocation structures such as labyrinth and cell structures, the fatigue limit can be improved notably. 相似文献

CeO2-doped diamond-like carbon (DLC) films with thicknesses of 180–200 nm were deposited by unbalanced magnetron sputtering. When the CeO2 concentration is in the range 5–8%, the residual compressive stress of the deposited films is reduced by 90%, e.g. from about 4.1 GPa to 0.5 GPa, whereas their adhesion strength increases. These effects are attributed to the dissolution of CeO2 within the DLC amorphous matrix and a widening interface between the DLC film and the Si substrate, respectively. 相似文献
