Two studies examined whether object names and functions act as cues to categories for infants. Findings indicated that both 14- and 18-month-olds were more likely to select the category match after being shown a novel category exemplar with its function than when given no additional cues. Only at 18 months did naming the objects enhance categorization. Naming facilitated 14-month-olds' categorization when enhanced with hints regarding the objects' core meaning. (Author/KB)
