| Abstract: | We examined the vocal stereotypy of three boys who were diagnosed with an Autism Spectrum Disorder (ASD). Results of functional analyses indicated that each participant's vocal stereotypy was maintained by non‐social consequences. For two participants, verbal reprimands were provided contingent on vocal stereotypy in the presence of a red card (RC). For the third participant, after verbal reprimands alone did not decrease vocal stereotypy, toys were withdrawn contingent on vocal stereotypy in the presence of the RC. For all three participants, vocal stereotypy was permitted without programmed consequences the presence of a green card (GC). The results showed that vocal stereotypy decreased in the presence of the RC for all three participants; however, vocal stereotypy came under inhibitory control of the RC for only one of the three participants. The potential utility of using punishment to develop stimulus control of automatically reinforced problem behavior in academic settings is briefly discussed.
