We evaluated 2 3-component multiple-schedule sequences--a response interruption and redirection (RIRD) treatment sequence and a no-interaction control sequence--using a multielement design. With this design, we were able to evaluate the immediate and subsequent effects of RIRD on 2 participants' vocal stereotypy. For both participants, RIRD produced an immediate decrease in vocal stereotypy and did not result in a subsequent increase. (Contains 1 figure.)
