Past research has shown that response interruption and redirection (RIRD) can effectively
decrease automatically reinforced motor behavior (Hagopian & Adelinis, 2001). Ahearn, Clark,
MacDonald, and Chung (2007) found that a procedural adaptation of RIRD reduced vocal
stereotypy and increased appropriate vocalizations for some children, although appropriate
vocalizations were not targeted directly. The purpose of the current study was to examine the
effects of directly targeting appropriate language (i.e., verbal operant training) on vocal
stereotypy and appropriate speech in 3 children with an autism spectrum disorder. The effects of
verbal operant (i.e., tact) training were evaluated in a nonconcurrent multiple baseline design
across participants. In addition, RIRD was implemented with 2 of the 3 participants to further
decrease levels of vocal stereotypy. Verbal operant training alone produced slightly lower levels of
stereotypy and increased appropriate vocalizations for all 3 participants; however, RIRD was
required to produce acceptably low levels of stereotypy for 2 of the 3 participants.
