Children With and Without Language Disorders

Alan G. Kamhi Memphis State University Memphis, TN Factors influencing the occurrence of trade-off effects among linguistic components were examined. Several linguistic measures were used to represent syntactic and phonological production in order to determine whether interrelationship patterns would vary across measures. Linguistic interactions present in imitated speech were compared to those from spontaneous speech. Group effects were explored by comparing data from children with language-learning disabilities, children with reading disabilities, and normally developing children. Results indicated trade-offs between some linguistic measures and positive relationships among others. More trade-offs were present in imitated speech than in spontaneous utterances. In general, interrelationship patterns were similar across groups. Interpretation of these results in reference to current models of sentence production is offered.
