The assumption that desirable behaviors that are rewarded immediately and systematically will increase, and that undesirable behaviors that are not rewarded or are punished will diminish or be extinguished, is known as:

BEHAVIOUR THERAPY

Explanation:

Behavior therapy or behavioral psychotherapy is a broad term referring to clinical psychotherapy that uses techniques derived from behaviorism. Those who practice behavior therapy tend to look at specific, learned behaviors and how the environment influences those behaviors.

Behavior therapy does not involve one specific method but it has a wide range of techniques that can be used to treat a person's psychological problems

In behavioral therapy, the goal is to reinforce desirable behaviors and eliminate unwanted or maladaptive ones while the behavior itself is the problem and the goal is to teach clients new behaviors to minimize or eliminate the issue.
