This study examined effects of message and program sensation value, sensation seeking, and drug use on visual attention to televised anti-drug public service announcements (PSAs) among 318 18–22-year-olds, who were placed individually in a simulated home environment with the opportunity to read from print media selections and/or watch a half-hour TV program including two presentations of the test PSA. The TV program was high or low in sensation value. High sensation seekers paid greater attention to high sensation value programming and to PSA embedded in such programming, whereas low sensation seekers paid greater attention to PSA embedded in low sensation value programs. Ongoing attention to a program may help to sustain attention to a subsequent PSA. The findings relate to an activation model of information exposure and indicate that program sensation value and sensation seeking are important factors to be considered in the placement oftelevised drug abuse prevention messages. 相似文献

ABSTRACT The assumptions underlying the traditional biomedical model of health and illness and criticisms of it are described. An examination of the historical development of ideas concerning cot (crib) deaths shows how early explanations, which were congruent with this model, came to be discredited. Because subsequent explanations have also been considered unsatisfactory, cot deaths have come to be regarded as medically problematic. The relationship of models of health and illness to cot deaths has therefore been exposed to an unusual degree of scrutiny. Two possible contending models, social epidemiological and socio-economic are identified, and their status vis-à-vis the biomedical model is considered. The choice as to which of these models is applied to cot deaths is shown to be not only of theoretical interest but also to have ethical implications for health care policy and medical practice. 相似文献
