“…Although researchers have found DTT to be an effective approach for teaching receptive labels for individuals with ASD, there are many variables that may alter the efficacy of DTT of receptive labels which warrant future research. Some of these variables include prompting and prompt fading procedures (Heckaman, Alber, Hooper, & Heward, 1998;Leaf et al, 2016b), introduction of new targets (e.g., Grow, Carr, Kodak, Jostad, & Kisamore, 2011;Gutierrez et al, 2009), instructional format (e.g., Taubman et al, 2001), topography of instructions and feedback (e.g., Leaf et al, 2017), staff training (e.g., following strict protocol or the use of clinical judgment; e.g., Grow & LeBlanc, 2013;Leaf et al, 2016a, and rotation of stimuli while teaching receptive labels as it pertains to the position of each of the stimuli on the table.…”
