In a previous study (Haryu, 1991) children were asked to choose one out of two objects, familiar and unfamiliar, as the referent of a novel label under conditions where it was clear that the novel label would refer to the familiar object, so that a familiar object would be chosen. Then the children were asked whether the label was referring to the familiar object. Three-year-olds were found to reject a novel label for afamiliar object presumably because they were inclined to find that category terms were mutually exclusive. But five-year-olds accepted the novel label for a familiar object. The present study aimed at testing the following two hypotheses.(1) Repeated questioning misleads three-year-olds in rejecting a novel label for a familiar object,(2) Five-year-olds tend to interpret the label as being consistent with their choice in a prior task. The result showed that the experience of choosing a familiar object in a prior task did not affect interpretation of the label.
