Comparison of acoustic correlates of phonatory control in the fluent utterances of 10 preschool-aged boys who were stutterers and in nonstuttering control subjects found significant differences between the two groups for shimmer measures. (Author/DB)

This study compared duration characteristics of single repetitions of single-syllable words in the speech of 15 preschool children near the onset of stuttering to those of 18 nonstuttering children. There appeared to be a tendency for repetitions of very early stutterers to be faster than repetitions of nonstuttering children. (Author/DB)

Analysis of pedigrees from parents of 69 preschool children who stuttered revealed that more male than female relatives ever stuttered but that female subjects who stuttered had more female relatives who ever stuttered than did male subjects. Segregation analyses suggest that transmission of a single major genetic locus increases the liability to…

Seventy-nine children (ages 3 through 7) were asked to discriminate between the speech (fluent and disfluent) of two puppets, identify the one who "speaks like you," and evaluate their speech. Children from age 3 showed evidence of some awareness of disfluencies but most children reached full awareness at 5. Negative evaluation of…

Preschool children (n=27) were followed for 2 to 12 years after stuttering onset. Findings indicated a marked deceleration in the mean frequency of stuttering-like disfluencies. Most of the reduction took place early, especially near the end of the first year postonset. Chronic and recovering stutterers could be distinguished by 20 months…

Sixteen preschool subjects were evaluated within several weeks after stuttering onset and followed for six months. Findings showed a strong tendency for reduction in stuttering-like disfluencies, number of head/face movements, and parent and clinician severity ratings of stuttering. Several subjects, including severe cases, exhibited complete…

Utterances from stuttering and normally speaking children, aged two through four years, were analyzed by clinicians specializing in stuttering, general clinicians, and university students (total n=25). Results indicated that the validity of the data language used by researchers to describe stuttered and normal speech in early childhood may be…

Interviews with parents of 87 preschool children within a year of a stuttering diagnosis found that onset tended to occur earlier than was previously thought and was sudden and/or severe in many cases; about twice as many boys as girls stuttered; and there was a positive relationship between severe stuttering and sudden onset.
