Final answer:
Michael should persist with his behavioral plan until he consistently achieves his goals, and then gradually modify the reinforcement to make the behavior self-sustaining.
Step-by-step explanation:
Maintaining long-term behavioral change requires consistent application of a successful plan and sometimes:
Gradual weaning off external reinforcement. To best ensure that the change in behavior lasts, Michael should continue implementing his plan until he has consistently met his final daily goal and then slowly adjust the reinforcement strategy. This approach allows behaviors to become internalized as habits, reducing the reliance on external rewards.
It is important to note that if Michael abruptly stops his plan upon meeting his goal, he risks reverting to old behaviors, as operant conditioning indicates that behavior is more likely to be maintained when reinforced. Furthermore, adding a punishment program could create aversion and is not as effective for long-term behavior maintenance as positive reinforcement. Instead, Michael should take a gradual approach and perhaps transition to a variable interval reinforcement schedule, which could make the behavior more resistant to extinction similar to the effects seen with variable-ratio schedules in gambling.
