Exposure to different forms of narrative media may influence children's development of theory-of-mind. Because engagement with fictional narratives provides one with information about the social world, and possibly draws upon theory-of-mind processes during comprehension, exposure to storybooks, movies, and television may influence theory-of-mind development. We examined 4–6 year-olds’ inferred exposure to children's literature, television, and film, using an objective measure that controls for socially desirable responding. Theory-of-mind was assessed using a battery of five tasks. Controlling for age, gender, vocabulary, and parental income, inferred exposure to children's storybooks predicted theory-of-mind abilities. Inferred exposure to children's movies also predicted theory-of-mind development, but inferred exposure to children's television did not.
