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.
