Response contingent stimuli and stuttering: issues and implications

The first papers concerning effects of response contingent stimuli (RCS) on stuttering and speech disfluency were published approximately 30 years ago. Research in this area fluorished until about 1980 after which relatively few studies have been reported. Reasons for the decline in interest are not altogether clear because crucial issues remain unresolved. This paper highlights and evaluates these issues and considers their implications for future research.
