The Grammatical Factor in Childhood Disfluency in Relation to the Continuity Hypothesis

Abstract

The relationship between grammatical function and disfluency was investigated in 15 normal-speaking children aged three years 11 months to four years 10 months. Pronouns and conjunctions appeared in significantly greater proportion among the subjects' disfluent words than among their total words. On the other hand, nouns, verbs, and prepositions had a significantly low frequency of disfluency. In many respects, the results were similar to those previously found for preschool stutterers, though a notable difference occurred in the case of verbs. The findings were interpreted to be in general accord with the hypothesis that a continuity exists between early stuttering and certain forms of normal childhood disfluency.
