What does "functional equivalent behavior" mean in behavior modification?

Functional equivalent behavior refers to teaching an individual a behavior that serves the same purpose as a behavior that may be undesirable or dysfunctional. In behavior modification, this means identifying an inappropriate behavior and teaching a more acceptable alternative that meets the same needs or achieves similar outcomes. For example, if a child engages in aggression to gain attention, a practitioner might teach them to raise their hand or use a phrase to request attention instead. This approach supports skill development while reducing problematic behaviors, emphasizing the importance of functionality in behavior change processes.

The other choices do not encapsulate the essence of functional equivalent behavior. Reinforcing compliance alone does not address the functionality of behavior. Assessment of unrelated behaviors does not contribute to modifying specific behaviors to achieve desired outcomes. Learning to avoid unwanted behaviors may lead to suppression but doesn't provide a functional alternative that meets the individual's needs. Thus, teaching a substitute behavior that serves the same function is crucial in effective behavior intervention.
