This is an incompatible behavior with pinching because he is not able to pinch while his hands are intertwined. She teaches him how to sit with his hands intertwined on his desk. (When he pinches his arms, she or a teacher’s aid comes over and tells him “no pinching.”) She decided to implement an intervention that utilizes DRI. She takes data on the behavior and discovers that it functions for attention. One of her students has recently begun to pinch his arms. Clark is teaching a classroom with six students with autism. Let’s look at a few examples of DRI in action: DRI is defined as “a procedure for decreasing problem behavior in which reinforcement is delivered for a behavior that is topographically incompatible with the behavior targeted for reduction and withheld following instances of the problem behavior (e.g., sitting in seat is incompatible with walking around the room) (Cooper, Heron, & Heward, 2007). Today, we are going to take a closer look at Differential Reinforcement of Incompatible behavior (DRI).
