Using versus liking: Young children use ownership to predict actions but not to infer preferences.

Three experiments show that young children (N = 384) use ownership to predict actions but not to infer preferences. In Experiment 1, 3- to 6-year-olds considered ownership when predicting actions but did not expect it to trump preferences. In Experiment 2, 4- and 5-year-olds, but not 3-year-olds, used ownership to predict actions, and 5-year-olds grasped that an agent would use his or her own property despite preferring someone else's. This experiment also showed that relating an agent to an object interfered with 3- and 4-year-olds' judgments that a more attractive object is preferred. Finally, Experiment 3 found that 3- and 4-year-olds do not believe that owning an object increases regard for it. These findings are informative about the kinds of information children use to predict actions and the inferences they make from ownership. The findings also reveal specificity in how children use ownership to make judgments about others, and suggest that children more closely relate ownership to people's actions than to their desires.
