Step-by-step explanation:
The intervention plan generally used for a misbehaving child is b. Behavior modification. Behavior modification involves using operant conditioning techniques to encourage desired behaviors through reinforcement and to discourage unwanted behaviors, potentially through punishment like a time-out. Sticker charts and token economies are common tools in behavior modification strategies tailored for children, wherein they earn a sticker or token for exhibiting positive behavior and receive a reward upon accumulation of a certain number of stickers or tokens. To effectively implement behavior modification, the reinforcement should be consistent and meaningful to the child, and focus is often placed on reinforcing positive behaviors rather than punishing the negative ones.
