Answer:
behavioral; counterconditioning
Explanation:
Behavioral therapist: The behavioral therapist usually treat mental health disorders. They try to modify unhealthy and potentially self-destructive behaviors.
Counter-conditioning: The term counter-conditioning is also referred to as stimulus substitution. It is one of the parts of behavior analysis that conditions an unwanted response or behavior towards a stimulus into a desired or wanted response or behavior by associating positive actions or behaviors to the stimulus. It is based on the phenomenon of classical conditioning.
Example: In the question above, Dr. Olsen is trying to modify behavior by conditioning a new response that is incompatible with a previously learned, undesired response.
In the question above, Dr. Olsen is most likely a behavioral therapist who is using counter-conditioning.
