This article examines the emergence of the ability to use a simple map to acquire information about distance in a larger space. It is commonly believed that scaling is a late achievement in childhood. The present study examined the origins of this ability by using the simplest of situations. In two experiments, we presented preschool children with a dot in a long thin rectangle, and asked them to use that representation to find an object in a corresponding location in a much larger sandbox. All 4-year-olds and a majority of 3-year-olds performed well on this task. We present a model that posits a simpler mechanism for scaling than that proposed in the existing literature.
