The effect of grammatical complexity upon disfluency behavior of nonstuttering preschool children
Journal of Fluency Disorders
The effect of grammatical complexity on the disfluency behavior of nonstuttering 3- and 4-yr-old children was examined. Thirty normal children repeated after the examiner 30 sentences which represented six different grammatical constructions. These grammatical constructions represented a range of grammatical complexity. The total number of disfluencies that occurred in each sentence type was compared. The occurrence of specific disfluency categories in each sentence type was also examined. Subjects produced significantly more disfluencies on passive sentences than on any other sentence type. The passive elicited significantly more interjections, word repetitions, and revisions than the other sentence types. The effect of sentence type on imitation performance was also examined. The auxiliary Have and negative sentence types elicited significantly more imitation errors than other sentence types. Initiation and fluency performance for individual subjects were also examined. The results of the present investigation suggest that when grammatical complexity is controlled, the relationship between disfluencies and grammatical complexity is complicated. When grammatical constructions were relatively difficult for children, complexity affected the occurrence of disfluencies. However, factors other than grammatical complexity affect the occurrence of disfluencies in pre-school children. © 1980.
