Registered Behavior Technician (RBT) Practice Exam 2026 - Free RBT Practice Questions and Study Guide

DRI is an example of blocking an undesirable behavior and using reinforcement to teach an appropriate alternative behavior. B, C, and D are incorrect because they do not address the concept of blocking and reinforcing in the same way that DRI does. B may seem like a correct answer because it mentions reinforcement, but it does not involve any type of blocking or alternative behavior. C and D are incorrect because they do not use reinforcement at all and instead focus on ignoring or punishing negative behavior. Overall, DRI stands for Differential Reinforcement of Incompatible Behavior and is a commonly used technique in behavior modification. In this approach, the undesirable behavior is replaced with a new, desirable behavior through a combination of blocking and reinforcement.
