BCBA exam practice question: Behavior-Change Procedures

Behavior-Change ProceduresDifficulty 3/5

A plan reinforces a learner for completing work while no hand-flapping occurs, and hand-flapping cannot occur while the learner is writing. Which procedure is in place?

  1. ADRA
  2. BDRI
  3. CDRL
  4. DDRO
Show answer and rationale

Correct: B. Differential reinforcement of incompatible behavior reinforces a response that is physically incompatible with the target behavior. DRA reinforces an alternative that need not be incompatible; DRO reinforces the absence of behavior; DRL reinforces reduced rates.

  • D — DRO reinforces the absence of the behavior, not a specific incompatible response.
  • A — DRA does not require incompatibility.
  • C — DRL reinforces a lower rate of the target behavior itself.
