A survey investigation of teenagers examined differential socialization effects of four news media on four types of political knowledge and behavior among several categories of youth on the basis of abilities and predispositions. Regression analyses of questionnaire responses from 280 seventh and tenth grade students show that TV news exposure is the strongest predictor variable. The broadcast media have a greater impact on current events knowledge than fundamental political knowledge, while a slight reversal occurs for the print media. Newspaper reading has the greatest effect on participation. There are predominantly uniform relationships across subgroups, providing little evidence that the news media produce knowledge or behavior gaps.
