Abstract

According to the category adjustment model of location estimation, children's responses are biased toward spatial prototypes, and these biases increase under conditions of uncertainty. Consistent with the model, 6- and 11-year-olds' biases toward prototypes increased across delays, especially for locations far from prototypes. Response biases also varied systematically with target frequency; however, responses were not always biased toward prototypes. In Experiment 1, 6-year-olds' responses to an infrequent target near the category boundary were biased toward a frequent target in an adjacent category. In Experiment 2, biases toward a frequent target were evident near prototypes. Both categorical information and children's experience with locations influence location estimates. Moreover, children's selective weighting of competing location cues changes between 6 and 11 years.
