Immediate and extended families of 66 stuttering children were investigated to determine frequencies of persistent and recovered stuttering. Recovery was far more common among females than males. Recovery or persistence was found to be transmitted, but the two types are not genetically independent, consistent with hypothesis that both forms share…

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…
