Sd. Perry et Wj. Gonzenbach, EFFECTS OF NEWS EXEMPLIFICATION EXTENDED - CONSIDERATIONS OF CONTROVERSIALITY AND PERCEIVED FUTURE OPINION, Journal of broadcasting & electronic media, 41(2), 1997, pp. 229-244
An experimental 3x3 factorial design was used to test the ability of e
xemplars to prime public opinion on an issue that was controversial, t
he issue of a prayer in school amendment. The experiment focused on ch
anges in perception of current public opinion and future public opinio
n as well as changes in personal opinion. Perception of public opinion
among Alabamans was affected by a disproportionate distribution of ex
emplars as was perception of future public opinion nationally. Actual
opinion also varied positively with exposure to different exemplar dis
tributions.
