title: Syntactic complexity, fluency, and accuracy of sentence imitation in adolescents.
abstract: The majority of work that suggests a relationship between syntactic complexity and the frequency of stuttering has been carried out with young children. In this paper, we investigate whether or not syntactic complexity exerts an influence on the frequency of stuttering in adolescent speech. Fourteen adolescents, 7 of whom stuttered, and 7 of whom were normally fluent, ages 10-18 years, participated in a sentence imitation task in which stimuli were divided into three classes of grammatical complexity. Results indicated that for both groups of speakers, normal disfluencies and errors in repetition accuracy increased as syntactic complexity increased. However, stuttering frequency did not appear to be affected by changes in the syntactic complexity of the target stimuli. Such findings suggest either a diminution of the effects of syntactic complexity on stuttering over the course of language acquisition or changes in the mix of chronic and nonchronic stuttering speakers from those used in earlier studies of the effects of linguistic structure on stuttering in children.
