To explore the relationship between the disfluent speech of normal speaking preschool boys and their parents, samples of spontaneous speech were obtained from 24 preschool boys, their mothers, and their fathers. Preschool boys were found to have a significantly greater number of total disfluencies than their mothers. The difference between boys and their fathers, in terms of total disfluencies, was not significant, and neither was the difference between mothers and fathers. Statistically significant correlations were found between boys and fathers in the disfluency category of disrhythmic phonations, and between mD0Srs and fathers in the category of interjections and in total disfluency.
