| Abstract: | The effects of political news on the mass audience are usually difficult to establish empirically. Recent models of mass communication effects have held that political knowledge is a better indicator of media reception than traditional measures of exposure. This claim is tested in two studies of attitudes toward Democratic and Republican leaders during the 1996 U.S. presidential primary campaigns. The impact of messages from three types of political talk radio (PTR) is examined: Rush Limbaugh, other conservative hosts, and liberal/moderate hosts. Political knowledge and exposure to talk radio are found to be equally good predictors of attitudes toward political leaders when studied separately. However, when tested against one another, exposure is the more effective measure. Agreement between Rush Limbaugh's messages and his audience's attitudes toward political figures is consistent and strong. Biased processing of PTR content by audience members with partisan predispositions contrary to those of the host is also examined. |
