The relationships between the length of the speech sample and the resulting disfluency data in 20 stuttering children who exhibited a wide range of disfluency levels were investigated. Specifically, the study examined whether the relative number of stuttering-like disfluencies (SLD) per 100 syllables, as well as the length of disfluencies (number…

Conversational speech of five children who stutter was recorded and then portions manipulated to modify interval duration and vowel duration. Results indicated that both interval and vowel durations moderately affected listeners' perception of stuttering. Generally, repetitions with short vowel and interval durations were judged as more…

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…

A study evaluated the language production of 12 children (ages 5-8) who continued stuttering for 36 months or more after onset, 10 who recovered 18-36 months post onset, and 10 who recovered within 18 months of onset of stuttering. The majority of the children performed in the average range on measures of language production. (Author/CR)

A study of children who stutter (n=12), who have recovered early from stuttering (n=12), and who recovered later from stuttering (n=12) compared the phonological characteristics of the three groups with a control group. Results indicated that poor phonological ability in the early stage of stuttering appeared to be a contributing factor to the…
