Disfluency of nonstuttering children in relation to specific measures of language,reading, and mental maturity

Speech samples from 92 first-grade children were quantified on the basis of disfluency types and judges' ratings of language level. Intelligence and reading scores were also obtained for each subject. Correlational analysis indicated that the measures of language performance, intelligence, and reading ability used in this study were not highly and significantly associated with frequency of disfluency whether considered by individual type, type combinations, or total disfluency.
