Twenty-five male stutterers and 25 male non-stutterers (5-13 years old) matched by age and speaking task, read or recited under normal and 113-, 226-, 306-, 413-, 520-msec. delayed auditory feedback conditions. (Author)

Reported are five studies on the use of delayed auditory feedback (DAF) with stutterers. The first study indicates that sex differences and age differences in temporal reaction were found when subjects (5-, 7-, 9-, 11-, and 13-years-old) recited a nursery rhyme under DAF and NAF (normal auditory feedback) conditions. The second study is reported…

Investigated with a 26-year-old male graduate student were the immediate and long-term effects of social reinforcement and feedback on the incidence of stuttering. The S's speech dysfluencies were recorded under baseline and intervention conditions in three settings: two classes the S taught and a weekly hour-long conversation period with peers.…

Several experiments that manipulate stuttering by the use of delayed auditory feedback (DAF) and the prolongation of speech are reported. In a study on six severe stutterers (aged 15 to 47), self monitoring as a source of reinforcement in the use of DAF reduced stuttering frequency. Stuttering frequency was investigated with six severe stutterers…

A survey of research and experimentation in the field of stuttering is presented for those engaged in teaching or studying speech therapy, speech pathology, and psychology. The background to stuttering is discussed as are definition, diagnosis, and measurement. The perceptual, organic, perseverative, expectancy, diagnosogenic, and conflict…
