In examining the many factors that play crucial roles in that process, the book explores the evolution of the senses, motor skills, social and emotional…

Discusses evidence that social understanding informs word learning in infants. Asks: (1) Is genuine social understanding necessary for word learning?; (2) Are social clues criterial for infants' learning?; (3) Can word learning proceed without aid of social understanding?; and (4) Is social clue processing too difficult for everyday word learning?…
