The relationship between grammatical function and disfluency was investigated in 15 normal-speaking children aged 3 years 11 months to 4 years 10 months. (Author)

Percent of stutterings predicted accurately by 84 stutterers, ages 8-16 years, for a list of 50 words read aloud was determined. (KW)

With the exception of revision and interjection for stutterers, the adaptation effect (reduction in disfluencies after repeated oral reading) was observed for each of six types of disfluencies among both stutterers and nonstutterers. (KW)

On two tests of phonetic manipulation 25 male stutterers were found to be inferior to matched controls. Results are reported to be consistent with previous findings of author and to interrelate with earlier research suggesting that some inadequacy in sound-making skills is an important aspect of stuttering. (Author/KW)

Transcriptions of the speech of 16 adolescent and young adult stutterers and 16 nonstutterers were rated by 12 fourth and fifth year speech/language pathology students as a sample from a stutterer or a nonstutterer. (PHR)

Expectancy in stuttering was investigated with 10 young adult stutterers under conditions that approximate more closely than in previous work the circumstances and mode in which expectancy is purported to operate. (Author/GW)

Studied with 10 Ss (ages 5-10 years) receiving speech therapy for stuttering were the reasons why some words were abruptly stuttered for the first time in the course of successive readings and the kinds of stimuli that play a role in stuttering. (Author/MH)

Twenty adult male nonstutterers became more fluent when pacing their speech with a metronome. The degree to which they became more fluent was within the range which has been reported for stutterers. This finding suggests that the effect of the metronome on stuttering is not primarily a result of distraction. (Author/KW)
