The mass media and changes in adolescents' political knowledge during an election cycle

Two questions are considered: to what extent do children's levels of political knowledge and news media use change during an election campaign? To what extent are levels of political knowledge related to levels and types of news media use? The hypothesis that news media use at one point in time is related to subsequent levels of political knowledge is tested using crosslagged partial correlation analysis. The patterns of political knowledge and news media use in January (prior to the 1976 primaries), late May and early June, and after the general election among a panel of high school students are examined. The means indicate a small increase in news media use and a more substantial increase in political knowledge. A greater increase occurs in political knowledge about campaign and election relevant institutions and processes than about other types of political institutions and processes. Limited support is provided for the hypothesized lagged influence of news media use; the impact varies with the political interest of the student and the type of news media used.
