A stimulus change following a behavior that results in that behavior occurring less often or not at all in the future.

A process that occurs when the addition of a stimulus immediately following a behavior results in a decrease in the future frequency of that behavior.

When a behavior occurs less often (or not at all) in the presence of certain conditions (SDp).

What are the key differences between these these two procedures? PTB co-founder Dana Meller distills the concepts with common and relatable examples we can identify with. Refer to BCBA® Task List (5th ed.) Sections B-9: Define and provide examples of operant extinction; and B-6: Define and provide examples of positive and negative punishment contingencies.

The concepts of punishment and reinforcement can sometimes confuse exam candidates. PTB co-founder Dana Meller clears things up, explaining nuances between the two and sharing her tips for making better discriminations on exam day.

A stimulus change that comes after a behavior.

The phenomenon that behavior is modified by consequences, even if a person is unaware of the contingency.

PTB co-founder Dana Meller provides insight to better understand why these concepts can be confusing, despite both leading to a decrease in behavior. Refer to BCBA® Task List (5th ed.) Sections B-6: Define and provide examples of positive and negative punishment contingencies; and B-9: Define and provide examples of operant extinction.

Test your knowledge of behavior principles with PTB co-founder Dana Meller as she breaks down a BCBA® mock exam question about the concept of punishers, clarifying their true definition based on their effect on behavior. Refer to BCBA® Task List (5th ed.) Sections B-6: Define and provide examples of positive and negative punishment contingencies; and G-16: Use positive and negative punishment (e.g., time-out, response cost, overcorrection).
