Individuals with autism spectrum disorder (ASD) or other developmental disabilities may experience rigid or repetitive behaviors, known as stereotypy. Current research determines effective interventions for increasing variability of vocal responding which effectively decrease stereotypic vocal responding. Lag schedules of reinforcement are a common theme among variability of vocal responding research. The purpose of this AB design study was to evaluate the effectiveness of a Lag 3 schedule of reinforcement in the teaching of variability of tacting. Results indicated that both variable and novel responses increased after the implementation of the Lag 3 schedule, but since these results are based off an AB design, further research that replicates effects needs to be done.
