In Episode 30, I finish up Section D: Fundamental Elements of Behavior Change!!! I talk about the BACB's Fourth Edition Task List item D-21 which states to use differential reinforcement (e.g., DRO, DRA, DRI, DRL, DRH). 
If you want more information on these topics, check out pages 595-611 of the Cooper et al. (2020) text.
