Reducing Vocal Stereotypic Behavior in a Child with Fragile X Syndrome by Implementing the Response Interruption and Redirection (RIRD) Method
The study sought to reduce vocal stereotypy of a boy with Fragile X syndrome. This was done by utilizing the response interruption and redirection (RIRD) method and adding reinforcers and a negative punisher to the original method. The vocal stereotypy was targeted in two different situations; playtime with an iPad and breakfast. In the iPad situation a reinforcer and a punisher were added to the RIRD method but in the breakfast situation a reinforcer and a conditioned reinforcer were added to the method. There was a visible decrease in vocal stereotypy in both situations, which suggests that adding reinforcers and a punisher works well with the original RIRD method. Experimental control was demonstrated with a mixture of changing criterion design and multiple baseline design by keeping the data stable at a close to zero slope while increasing the criterion. Since previous studies have almost solely focused on autistic individuals, this study adds to the knowledge of whom the treatment benefits.
