Communicative skills in children with specific language impairments: a comparison with their language-matched...

The purpose of this study was to compare the pragmatic skills of five children with Specific Language Impairments (SLI) and their Mean Length of Utterance-matched younger siblings, thus in part controlling for home language environment and expressive language level. Data were videotaped as mother-child free play in the home. Children's communicative acts were coded on three levels (social interchange, speech act, and conversational). Analysis of each level separately indicated generally comparable performance within sibling pairs. However, when the three levels were integrated into a measure of pragmatic flexibility, the children with SLI were found to demonstrate a more varied repertoire than their younger, normally developing siblings.
