Abstract

Researchers have demonstrated the effectiveness of tact prompts to establish single responses to questions about intraverbal categories. Scenic pictures, a visual depiction of multiple exemplars belonging to a stimulus class, may increase the likelihood that individuals will emit multiple responses when answering categorical questions, and promote response variability. The purpose of this study was to extend Glodowski and Rodriguez (2019) by evaluating the effectiveness of a larger array of visual stimuli and progressive time delay on varied intraverbal responding with individuals diagnosed with autism spectrum disorder between the ages of 8 and 17 within a private school for individuals with autism. We successfully demonstrated the efficacy of SPP + PTD in promoting the acquisition of intraverbal categorization and demonstrate concomitant increases in response variability and novel responding with three male children with ASD.
