In a reply to a review of replicated findings on stuttering, the author adds 14 points concerning symptoms, prevalence, incidence, stutterer-nonstutterer differences, and variability of stuttering. He takes exception to the review's statements on treatment and theories of stuttering. (CL)

The author responds to a review of replicated findings about stuttering and examines issues related to its possible genetic source, the role of hemispheric assymetries, and fluency-inducing conditions. A theoretical framework for the replicated findings is explored. (CL)

Replicated findings from research on stuttering are reviewed according to five major topics (sample subtopics in parentheses): symptoms, prevalence, incidence; stutterer-nonstutterer differences (personality factors, intelligence); variability of stuttering (variation by time, situation, language factors); treatment; and theories. The theory…

The paper argues that listeners are unable to judge unit-by-unit occurrences of stuttering acceptably. Reasons for this state of affairs and its implications for therapy, theory, and research are analyzed. An alternative speech production definition with its implications is proposed, and a diagnostic method of validating authentic stuttering is…
