Children's Pragmatic Inferences as a Route for Learning About the World

This study investigated whether children can infer category properties based on how a speaker describes an individual (e. g., saying something is a small zib implies that zibs are generally bigger than this one). Threeto 5-year-olds (N = 264) from a university preschool and a children's museum were tested on their ability to make this sort of contrast inference. Children made some inferences from adjective choice alone (Experiment 1); performance increased as more cues to contrast were added (Experiments 2 and 3). Control studies show that these findings are not due to the particular properties used or the structure of these tasks (Experiments 4 and 5). These findings suggest that sensitivity to speakers' production choices may help children learn about the world.
