Abstract
Individuals with autism spectrum disorder (ASD) may face challenges with reporting past behavior. Although some behavior-analytic studies have shown success with increasing these reports, the use of materials within activities that do not repeat has not been assessed (e.g., Shillingsburg et al., 2017). Thus, the purpose of the current study was to expand upon previous research (e.g., Shillingsburg et al. 2017; 2019) by utilizing novel materials within activities completed and examining the use of partial textual stimuli within an interactive task to increase reports of past behavior for one child with autism. The results showed an increase in reports of past behavior following intervention across three activities as well as an increase in varied responses.
