Cognition and communication: referential strategies used by preschoolers with specific language impairment.

Ten children with specific language impairment and 10 children with normal language development were asked to describe objects so that a listener could select them. Each trial targeted two out of a group of three toys. The targeted objects were identical or were similar in size or color. Children in the two groups did not differ in referential success, although children in both groups found the size items more difficult. Content analysis of the messages did reveal differences in the referential strategies used most frequently. Children with specific language impairment were more likely to mention the attributes of each object separately, rather than to describe the characteristics common to a pair of objects. Children in both groups talked about separate objects more often when talking about size than about color or object type. Use of this strategy could indicate the effects of attentional capacity on children's solutions to communication tasks.
