Answer:
The answer is participant modelling.
Step-by-step explanation:
This model is used when a psycotherapist "models" a behaviour, and expects the client to imitate it. This can be done through role-playing, as in the example, or in a real environment. For instance: a client may desire to learn how to order food in a restaurant. The therapist would take the person to a restaurant and model appropriate behaviours, then assist him in performing them.
