title: Effects of sampling context on the expressive language of children and adolescents with mental retardation.
abstract: This study was designed to determine whether conversational samples of language should be supplemented with samples obtained in narrative, or storytelling, contexts when evaluating the expressive language skills of individuals with mental retardation. Language samples were elicited in both conversational and narrative contexts from 16 school-age individuals with mental retardation and 16 typically developing children matched to them on MA. An analysis of the samples demonstrated that both groups produced more syntactically complex language in narration than in conversation, whereas they were more talkative in conversation than in narration. These results suggest that conversational and narrative contexts should be used together when evaluating the expressive language performance of individuals with mental retardation.
