This study draws from cognitive theories of learning to examine the role of different forms of television news viewing in political knowledge. Data from two-wave panel data reveal that performing an additional task unrelated to television news, or task-irrelevant second screening, is related to detrimental cognitive outcomes. Unlike past research, performing an additional task relevant to television news, or task-relevant second screening, does not contribute to political learning. Television news exposure is positively related to political learning. Theoretical implications of the results are discussed.
