Answer:
All of the Above
Step-by-step explanation:
Functional Communication Training: Is a common way to ensure the client can express what they want or need in a more functional and appropriate manner (speech, pictures, signs, ipad, etc.)
Differential Reinforcement of Incompatible Behaviors: Is a weakening procedure that is based on reinforcement. The behavior that has to be reinforced is actually not the target behavior, as this would most likely strengthen it, but rather is a behavior that is wanted but the client can't use by themselves.
Wait for the client to de-escalate themselves: This is when you wait for the client to return to their neutral state of mind in case they got angry or they were causing some unwanted actions.
