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

The effectiveness of messages with different logical styles might change, regardless of factual content, depending on receiver intent to practice prevention. Predictions based on reactance theory, postdecisional regret, and language expectancy theory were tested in a study altering logical style (inductive versus deductive) and language intensity in messages to parents advocating family sun safety. A prediction that deductively formatted messages would be inferior for parents not intending to act was confirmed in analyses of their reported sun protection, supporting a reactance theory explanation. For parents with mixed intentions to increase protection for themselves or their children, deductive messages were most effective, consistent with postdecisional regret processes. High language intensity enhanced both effects. Reactance effects among nonintenders completely disappeared in a follow-up survey, but language intensity effects remained. The influence of message features varies by stage of progression to action, which has practical implications for tailoring health communication to individual needs. 相似文献

This research compares two contrasting perspectives of social contagion processes associated with the organizational outcome variables of commitment and role ambiguity in organizations. The two perspectives are structural equivalence (which focuses on the positions of individuals in social networks) and cohesion (which focuses on an individual's direct communication contacts). It was hypothesized that structural equivalence would be more associated with role ambiguity and that commitment would be more associated with cohesion. The relationship between these variables and multiplex content networks was also studied. It was hypothesized that commitment was a much more broadly based concept in the sense that a number of functional content networks systematically relate to it. On the other hand, role ambiguity was hypothesized to be more closely associated with uniplex networks, especially those related to job duties and organizational goals. While there were exceptions, generally the research results supported the hypotheses relating to multiplexity. The hypotheses that structural equivalence was more associated with role ambiguity and that commitment was more associated with cohesion also were supported in this research. 相似文献
