Remembrance of Coverage Past: Agenda-Setting Effects of Television News Coverage and the Effects Decay Curve.
Watt, James H.; And Others
To derive a model for testing, research questions were formulated which asked how long news coverage viewed in the past continues to influence the perceived salience of issues and the rate at which the influence drops off. To do this, some common factors that have been shown to affect public perceptions of issue salience, such as the prominence of the media coverage, the obtrusiveness of the issue being covered, and the amount of past coverage of the issue were addressed in the research. Three issues (inflation, Iran, and the Soviet Union) were investigated over an 1826-day period, using the daily prominence of television coverage obtained from television news archives and daily salience of the issues interpolated from monthly achieved poll data. The size of the relationship between accumulated coverage and issue salience was found to decrease with the amount of coverage of an issue prior to the beginning of the study period. A new unobtrusive issue (Iran) was found to have the strongest agenda-setting effects and more rapidly declining coverage effects than other issues. The model must be further tested in other types of agenda-setting studies, including individual-level analyses. Additional replications with other issues are necessary to further confirm the impact of issue age and obtrusiveness. These should include media other than television, to insure that media-specific effects are not confused with coverage effects. (One table of data and five figures are included; an appendix of poll dates and types, and 42 references are attached.) (RS)
