When rewards are introduced during a behavior, the reinforcer becomes a bribe. If your learner does this, use shaping to help your learner adapt to and learn to accept reinforcement for those positive behaviors. Nine-year-old Liam often gets frustrated when doing his homework, especially math. A response high in resistance to extinction will take a longer time to become completely extinct.

For the purpose of the rest of this article we will focus on planned consequences that are intended to change the behavior of a child. The advantages of differential reinforcem If Ben succeeds and doesnt have a tantrum, he gets the candy. When we apply a consequence after a behavior, we hope for behavior change in the desired direction, but reality may find the opposite occurs.
