A Therapist Wants to Implement a Token Economy

A therapist wants to implement a token economy. To help ensure that the program is effective, the therapist should:

A) create a plus and minus system, awarding tokens for desired behavior and taking tokens for undesired behavior.
B) define the behavior to be reinforced and establish expectations for earning tokens.
C) first create a bare minimum standard for living comforts so that the tokens and rewards become more desirable.
D) be generous when initially awarding tokens to increase interest in the reward system.
