Antecedent interventions are strategies implemented before a problem behavior occurs to reduce its likelihood by shaping the environment and the task. Providing choices, priming, or altering task difficulty are classic examples because they change what happens just before the behavior, making the situation more predictable, manageable, and engaging. Giving choices increases the chances of selecting a reinforcing activity, priming prepares the learner for what’s coming next, and adjusting task difficulty reduces frustration or effort that might trigger a problem behavior.

The other options describe responses that happen after the behavior occurs. Delivering reinforcement following the problem behavior can reinforce the act itself if the reinforcement is tied to that moment. Ignoring the behavior after it occurs is not changing the setup before it happens, and timeout is a consequence applied after the behavior.
