Abstract
Perceptual similarity among concept members has been viewed as inadequate to motivate concept formation. Instead, it has been argued that intuitive beliefs about the world offer more structured motivation for concepts. Our research explores children's beliefs about the relations between perceptually based similarity among things and their predicted behaviors. We focus on form-function correspondences as fundamental components of very young children's belief systems. Groups of 2- and 4-year-old children were asked to choose which of 2 line-drawn animals evidenced a particular "function," a special behavior. Even the youngest children showed sensitivity to form-function correspondences by selecting the animal whose form afforded the particular function. A second study investigated how form-function correspondences affect the relative influences of perceptual similarity and shared labels over patterns of children's inference. Perceptual similarity, if "motivated" by intuitive beliefs about correspondences between form and function, was found to be sufficient basis for inference and a more robust basis than shared labels when children attributed meaningful functions to novel animal forms.
