Previous research has indicated that adolescents who intend to smoke differ from those who do not intend to smoke in the imagery they associate with smoking. The present study examined relationships among self-image, ideal self-image, image of smokers in general and image of models in cigarette ads for seventh-grade students. The strongest finding was a positive correspondence of smokers image to self-image in predicting intention to smoke cigarettes. This correspondence between smokers image and self-image derived from a relative depression of self-image in combination with a relative elevation of smokers image for youth who were more likely to report intentions to smoke. There was also a trend for the ideal self-image of youth with greater intentions to smoke to be similarly depressed. It is suggested that when both self-concept and aspirations for self-improvement are diminished, smoking may seem particularly desirable as a means of enhancing identity.  相似文献

In two studies, co-workers of persons with disabilities were taught to use coincidental training procedures while completing their own jobs. In Study 1, the effects of coincidental training on the salad-making skills of 3 trainees with mild and moderate mental retardation were evaluated. Coincidental training by co-workers resulted in improved accuracy of the salad-making skills of the trainees. In Study 2, trainees were also coincidentally taught to make quality-control checks of their salads. An alternating treatments and multiple baseline design indicated that the trainees more readily acquired the skills when taught to check the correctness of their work.  相似文献

This paper presents 10 general observations about current software for instruction in psychology and examines selected examples employing four instructional techniques for computer-assisted instruction. We find that although the number of programs employing experimental or data-oriented approaches to psychology as a primary vehicle of instruction is increasing, tutorial drill and practice programs and gaming are not well represented.  相似文献
