An RBT runs a reinforcement procedure but often delivers the reinforcer 30–60 seconds late. The data show no improvement. What is the most accurate conclusion?
- AThe learner needs a punishment procedure instead
- BThe reinforcer is not preferred, so the supervisor should select a different one
- CThe procedure is ineffective and the supervisor should discontinue it immediately
- DThe data cannot show whether the procedure works; it was not run as written
Show answer and rationale
Correct: D. Delayed delivery is a procedural-fidelity failure. When the procedure is not run as designed, the data reflect the flawed implementation, not the procedure's effectiveness. The correct step is to report the fidelity problem and correct implementation before drawing conclusions.
- B — Preference cannot be judged when the reinforcer was delivered late.
- C — You cannot evaluate a procedure that was not actually implemented.
- A — Changing procedures is the supervisor's decision and is not supported by these data.
