What does DRA stand for in differential reinforcement?

Differential Reinforcement of Alternative Behavior (DRA) is a behavioral intervention strategy used in the field of communication disorders and behavior analysis. The fundamental goal of DRA is to increase the frequency of a desirable alternative behavior while simultaneously decreasing an undesired behavior. In this approach, an individual is reinforced when they exhibit a specific, appropriate behavior that serves as an alternative to the target behavior that is being reduced.

This method is particularly effective because it replaces an undesirable behavior with a more acceptable one rather than simply trying to eliminate the negative behavior without providing an alternative. By emphasizing the reinforcement of appropriate behaviors, DRA can lead to more sustainable and positive behavior changes. The term 'alternative' specifically highlights the key aspect of this approach, as it focuses on promoting functional and socially acceptable behaviors as substitutes for inappropriate ones.

Overall, the use of DRA in behavioral methods is aimed at modifying behavior in a constructive way, facilitating better communication and social interactions in individuals with communication disorders.
