Two experiments examined stereotype and risk factors in suntanning. In the first, subjects formed more positive impressions of a target described as having a suntan than of a control target. Ratings were not as positive, however, if the tan was portrayed as having been intentionally sought. A negative facet to the tan stereotype, in terms of perceived vanity, was also observed. In the second, subjects observed a videotape documenting the risks associated with sun exposure either before or after responding to a questionnaire dealing with attitudes and beliefs about suntanning. The results were consistent with the interpretation that the tape influenced observers in the direction of perceiving a tan as less attractive and enhancing their concern about the dangers of tanning. Subjects displayed the "optimistic bias" effect (Weinstein, 1980) in their estimated likelihood of getting skin cancer. While those with higher reported tan levels were more likely to endorse the attractiveness stereotype associated with a suntan, there was minimal evidence that these individuals were apprehensive or concerned about the risk factors. Their responses to a number of items suggested a measure of resistance or denial. Women generally indicated greater awareness and concern about risks than did men. The results of both studies suggest the important role played by images perceived to be associated with suntanning. In the context of mounting evidence regarding the carcinogenic properties of sun exposure, implications for changes in tanning behavior were considered.  相似文献

Contemporary understanding of brain functions provides a way to probe into the mystery of creativity. However, the prior evidence regarding the relationship between creativity and brain wave patterns reveals inconsistent conclusions. One possible reason might be that the means of selecting creative individuals in the past has varied in each study. By distinguishing creative potential as open-ended versus closed-ended based on theoretical views, this study examined different brain wave patterns and cortical control abilities in relation to different creative potentials by using electroencephalogram (EEG) biofeedback equipment. The results demonstrated that participants’ performance on the open-ended creative problem was positively related to EEG alpha frequencies, whereas performance on the closed-ended creative problem was related to larger variability in EEG dynamics between alpha and beta waves when performing either open-ended or closed-ended creativity tasks. Further, better control in changing states of brain wave activities according to the EEG biofeedback signals could predict closed-ended creativity performance. Open-ended creativity was related only to the enhancement of alpha signals. These results help clarify previous inconsistent findings, reveal different natures of distinct creativities, and further suggest ways to improve different aspects of creativity with modified biofeedback procedures.  相似文献

Scholars have long recognized the impacts of gang membership on adolescents. While some have focused primarily on the negative effects, this seeks to understand the nuanced reasoning and results of joining a gang explicitly on the youth’s perceptions of self-esteem, efficacy, and identity. Using the longitudinal assessment of the Gang Resistance Education and Training (GREAT) program, propensity score matching was conducted on four attitudinal measures to determine whether positive outcomes were seen among adolescents reporting one-time gang involvement. Results indicate a positive effect on self-identity measures. Discussion of these findings illustrates the need for future research and policy implications.  相似文献

Explanations of the cause of the Challenger disaster by the Presidential Commission and by communication scholars are flawed. These explanations are characterized by a common tendency to emphasize the technical and procedural aspects of organizational life at the expense of the cognitive and ethical. Rightly construed, the Challenger disaster illustrates both the need for a revived art of rhetoric and the importance of putting in place the political and social conditions that make this art efficacious in furthering cognitive understanding and ethical conduct.  相似文献
