Categorization of real and replica objects by 14- and 18-month-old infants

► Addressed the question of whether infants categorize replicas of objects in the same way as they categorize real objects. ► 14- and 18-month-olds were tested in a sequential touching task. ► Mean run length, number of contacts, and appropriate actions did not differ between real and replica objects. ► Replicas are appropriate stimuli to use to address questions of infants' categorization.
