Abstract
PURPOSE: This study investigated aspects of morphology, syntax and pragmatics in children with Specific Language Impairment (SLI). These areas of language were investigated by evaluating children's answers to wh-questions.
METHOD: Elicited production methodology was used to evoke answers to three types of wh-questions. There were 54 participants: 18 children with SLI (mean age = 5;3); 18 language-matched children matched on mean length of utterance (mean age = 3;4) and 18 age-matched children (mean age = 5;3).
RESULT: The SLI group demonstrated comprehension of the wh-questions, as revealed by their answers using the appropriate syntactic category. Children with SLI also demonstrated knowledge of pragmatics by using a pronoun to refer to a discourse referent that was previously introduced as a full noun phrase. Unlike the control children, children with SLI did not show sensitivity to one measure of the Maxim of Quantity; they gave more full sentence answers to wh-questions in contexts when most speakers would give a shorter, fragment answer. The tense-related morphology was also frequently omitted from children's answers.
CONCLUSION: The experiment revealed that children with SLI did well on syntactic and pragmatic measures. The greatest challenge was in providing tense-related morphemes in their answers to questions.
