Background: Response-contingent time-out has been shown to be an effective technique for enhancing fluency in people who stutter. However, the factors that determine individual responsiveness to time-out are not well understood. Aims: The study investigated the effectiveness of using response-contingent time-out to reduce stuttering frequency in…

This study evaluated use of the interpolation of reinforcement effect, which combines intermittent (INT) and continuous reinforcement (CRF) schedules, with four young children with autism using a free-operant preparation. Results suggest that responding may be less resistant to extinction following interpolated CRF reinforcement than following INT…

A parent-conducted program of verbal response-contingent stimulation was effectively used to reduce stuttering to near zero levels in 12 children (younger than age 5). Treatments were completed in a median of 10.5 1-hour clinic sessions and 84.5 days. (Author/DB)

This is a review of the contingency management literature and current related treatment programs for stuttering in childhood: the Lidcombe Program, Gradual Increase in Length and Complexity of Utterance (GILCU), and Prolongation (PS). Treatment efficacy research has shown these treatments to be effective and efficient for children, but there…
