What does functional equivalence mean in behavior analysis?

• A. Functional equivalence means the replacement behavior serves the same function as the problem behavior; e.g., using a break card to escape demands instead of shouting.
• B. Functional equivalence means the replacement behavior must be an exact physical imitation of the problem behavior.
• C. Functional equivalence means the function of the problem behavior is intentionally changed by the replacement.
• D. Functional equivalence means suppression of the problem behavior with punishment.

Answer: (A)

Functional equivalence means choosing a replacement behavior that yields the same outcome or access to the same reinforcer as the problem behavior. In practice, if shouting was used to escape demands, a replacement like a break request or break card should give the same escape consequence. The important point is the function, not an exact physical imitation—the form can be different as long as the outcome is the same. This approach helps the learner get the desired result in a socially acceptable way, rather than relying on the disruptive act. It’s not about changing the function of the behavior or using punishment to suppress it; it’s about providing a functionally equivalent way to achieve the same result.
