In differential reinforcement, what do the letters DRA stand for?

The correct answer, Differential Reinforcement of Alternative behavior, refers to a specific strategy used in behavior modification within the context of ABA (Applied Behavior Analysis). This technique involves reinforcing an alternative behavior that is more appropriate or desirable instead of the undesired behavior.

By focusing on an alternative behavior, practitioners aim to reduce the frequency of the undesired behavior while simultaneously promoting positive behavioral changes. For example, if a child is engaging in disruptive behavior to gain attention, they might be taught to raise their hand instead. Whenever they appropriately raise their hand, they receive reinforcement, which helps strengthen that alternative behavior.

This approach emphasizes the importance of teaching and reinforcing acceptable behaviors rather than just trying to eliminate undesirable ones, which can lead to more effective and sustainable behavior change. The focus on "alternative" behavior highlights the key component of providing an option for the individual to achieve the same function (like attention or access) through acceptable means.
