Secondary Effects of Extinction and Punishment

Summary: Extinction and punishment both reduce behavior, and both come with side effects you'll see in the room before anyone else does. Extinction can produce a burst, induced aggression and emotional responding, and spontaneous recovery. Punishment can produce emotional and aggressive reactions, escape and avoidance of you or the setting, and the learner copying the punitive behavior. None of these mean the plan failed. Your job is to recognize them, stay consistent, keep the data, and tell your supervisor.

Every procedure that reduces behavior does more than just reduce that one behavior. It ripples. The learner reacts to the change, and some of those reactions are predictable enough that the field has names for them. These are the secondary effects, and the third-edition task list pulls them out as something you specifically need to recognize.

Here's why that matters for you and not just for your BCBA. You're the person in the room when the side effect shows up. Your BCBA designed the plan from a desk, days ago. You're the one watching a kid who's suddenly screaming louder, or flinching when you walk over, or hitting a peer for the first time. If you don't know these effects are normal and expected, you'll read them as the plan backfiring, and you'll either cave or improvise. Both make things worse. If you do know them, you stay steady, you write it down, and you flag it. That's the whole skill here.

One thing up front. You won't be designing or independently running punishment procedures, and good programs lean on reinforcement and extinction first. But you have to understand punishment's side effects, partly for the exam and partly because the field treats them as a major reason to avoid punishment when something gentler will do the job.

We cover extinction's mechanics in depth on the extinction page. Here we're focused on the fallout, the things that happen to the learner when you stop delivering the reinforcer.
