RIRD, neutral sound, suppress, sound assessment, extinction, punishment


Response Interruption and Redirection (RIRD) was compared to no-interaction, continuous neutral sound, and contingent neutral sound in order to determine the mechanism by which RIRD functions to suppress vocal stereotypy in children diagnosed with autism spectrum disorder. A neutral sound was determined through the use of a preference assessment of various sounds. Use of a neutral sound did not suppress vocal stereotypy in participants. Manipulating the amount of time with a sound playing did not have an effect on vocal stereotypy either. These results suggest that it is unlikely that RIRD suppresses vocal stereotypy through an extinction-like effect. Rather, it is more likely that RIRD suppresses vocal stereotypy through a punishment-like effect.
