Abstract
In a longitudinal study of the vocal development of five handicapped infants who had been hospitalized soon after birth, examples of cry and noncry sounds collected at weekly intervals were analyzed in terms of selected features (e.g. mood, intent and target listener). Results suggested that for the three more delayed infants, vocalizing throughout the observed time period remained largely a form of protest or self-entertainment with some instances of social interaction. The two less handicapped infants, demonstrated acquisition of effective use of sounds in social interaction. It was concluded that the high rate of self-stimulatory vocalizing by the three more delayed infants may have inhibited the development of more appropriate vocal behaviour.
