This study investigated attitudes about body weight and appearance in a group of young adults. Undergraduate psychology students at the Flinders University of South Australia and at the University of Vermont were asked about their weight and dieting, consciousness about their body, the degree to which their weight had interfered with social activities, their perceptions about the causes of obseity, and their stereotypes about fat and thin men and women. Although 20% of the sample was overweight, 50% of subjects perceived themselves to be overweight to some degree. As expected, weight was a much greater issue for women, who felt more overweight, dieted more, expressed more body consciousness, and reported that weight had interfered more with social activities than did men. Also as expected, Vermont students reported greater frequency of dieting, more concern about weight, and more body consciousness than did students in Australia. Finally, men and women in both cultures stereotyped obese targets significantly more negatively than they did nonobese targets. The results indicate excessive and maladaptive concerns with weight in general, and among women and U.S. students in particular.  相似文献

Default technologies evolve from failure. Within the realm of human behavior, technologies based on the use of aversive contingencies can be conceptualized as default technologies because they come into play when natural contingencies or positive reinforcement fail to produce a desired behavioral outcome. Historical as well as contemporary events suggest that it is a mistake for behavior analysts to advocate for the adoption of aversive technologies. We must, however, continue to play a leading role in the development of such technologies so that they will be used in an appropriate manner. Furthermore, the eventual elimination of aversive technologies will be possible only through continued, careful, and experimental analysis of the contexts of failure in which they are born.  相似文献

The authors describe a career information hotline for rural and farm residents affected by the farm crisis as one way a university career center and extension division can make their resources more generally available to residents. The rural crisis is real, but a crisis brings opportunities. There are opportunities to provide needed services and help ease the personal cost for families and reduce the declining quality of life in rural communities.
