Which of the following is NOT a factor that influences the efficacy of punishment?

• A. The punisher delivered immediately after the behavior.
• B. The punishment is applied consistently to every occurrence.
• C. The punisher's intensity is high.
• D. The age of the person receiving the intervention.

Answer: (D)

The core idea is that punishment works best when the consequence is closely tied to the exact behavior through a clear, reliable contingency. Punishment that is delivered immediately after the behavior strengthens the association between the action and its consequence, making it more likely the behavior will decrease. When the punishment is applied consistently to every occurrence, the learner can predict the outcome, which stabilizes the learning and reduces the chance of the behavior reoccurring. Higher intensity tends to make the consequence more noticeable and effective at suppressing the behavior, though it must be used with care to avoid harm or negative side effects. The age of the person receiving the intervention does not determine how effective punishment will be in reducing a behavior; the basic operant principles apply across ages, so age isn’t a factor here.
