In ABA, punishment is a procedure that follows a behavior and decreases the likelihood that the behavior will happen again — it is a technical term, not a moral one. Punishment can take two forms: positive punishment (adding something unpleasant) or negative punishment (removing something preferred, like a privilege). Modern ABA strongly prioritizes reinforcement-based strategies and uses punishment only rarely, with careful ethical review and family consent. The first goal is always to teach replacement behaviors and build skills rather than suppress behavior. Get a clearer view of how consequences shape behavior in Understanding the ABC ABA Model.
