Why do you want to change the behaviour and what benefits will change bring?
Make a program proposal incorporating all relevant conditioning principles. That might include: the use of positive and negative reinforcement, schedules of reinforcement, punishment, shaping, modeling, primary and secondary reinforcers, extinction, stimulus generalization/discrimination. Reflect the following questions:

What are the plausible explanations for the outcome?
If it was successful, propose a brief plan to maintain the change. If not, propose an alternate plan that can be carried out in the future.
