Do Words Facilitate Object Categorization in 9-Month-Old Infants?

Presented 9-month-old infants with slides of drawings of pigs and rabbits, and tested the relative success of two auditory accompaniments in facilitating subsequent categorization of the slides. Found that infants paid more attention to presentations when they were accompanied by sound (words or tones) rather than musical tones, and paid more attention to novelty when accompanied by words.
