Children's storybooks often contain fantasy elements, from dragons and wizards to anthropomorphic animals that wear clothes, talk, and behave like humans. These elements can impact children's learning from storybooks both positively and negatively, perhaps due in part to their ability to capture children's interest and attention. Prior research has found that children prefer realistic to make-believe stories, but little is known about children's preferences for anthropomorphic characters. The present study examines U.S. children's preferences for fantasy and anthropomorphism in storybooks. Seventy-two 4- to 6-year-old children (M = 65.74 months, SD = 10.84 months) were presented with 10 pairs of books (fantasy/anthropomorphic vs. realistic) and asked to select which book they liked better and why. Children chose fantasy but not anthropomorphic animal stories significantly more often than expected by chance. Children's preferences were not related to age or gender, and they most often justified their choices with references to the storyline. Implications for creating and selecting media are discussed, since children learn best when learning materials align with their interests.
