Differential Reinforcement is a powerful evidence-based strategy for increasing appropriate behaviors while reducing interfering behaviors. In this two-hour virtual session, participants will learn how to use Differential Reinforcement to strengthen desired behaviors by intentionally reinforcing one class of behavior while withholding reinforcement for others. The training will focus on applying several Differential Reinforcement procedures, including Differential Reinforcement of Alternative Behavior (DRA), Differential Reinforcement of Incompatible Behavior (DRI), and Differential Reinforcement of Other Behavior (DRO).
