Which type of DRA focuses on teaching a communication response to replace the problem behavior?

The correct answer is focused on Functional Communication Training (FCT), which is a specific form of Differential Reinforcement of Alternative behavior (DRA). FCT is designed to teach individuals more appropriate communication skills to replace problem behaviors that serve a communicative function. For instance, instead of engaging in disruptive behavior to gain attention, a child may be taught to say "excuse me" or raise their hand. This communication response is reinforced, thereby reducing the occurrence of the original problem behavior.

FCT is effectively used in behavioral interventions to enhance an individual's ability to convey their needs and wants in a socially acceptable manner, thereby improving their relationships and interactions with others. This reinforces not only the alternative behavior but also the importance of communication as a vital social skill.
