Abstract
Anti‐drug media campaigns have changed the drug‐consumption behaviors of high sensation seekers in part through a campaign strategy called SENTAR. This strategy relies largely on high sensation value messages, which contain structural and content features that elicit sensory, affective, and arousal responses. To learn more about the persuasiveness of high sensation value ads, this investigation focused on the processing of anti‐heroin PSAs by 200 young adults. Of specific interest was the influence of perceived message sensation value on three types of processing (argument‐based, narrative, and sensory), two affect variables (sympathetic distress and stimulated excitation), and anti‐heroin attitudes. Sensation seeking was examined as a moderator of these effects. In general, sensation seeking moderated the effects of perceived message sensation value and sensory processing on sympathetic distress and anti‐heroin attitudes. Additionally, high sensation seekers’ anti‐heroin attitudes were largely influenced by narrative and sensory processing, while low sensation seekers’ anti‐heroin attitudes were relatively unaffected by the anti‐heroin ads.
