G15 | ABA Exam Review

Introduction to Extinction

  • Extinction is a major behavior change procedure in the context of Applied Behavior Analysis (ABA).

  • It is one of the three primary methods of behavior change, alongside reinforcement and punishment.

  • Extinction is a powerful tactic but must be implemented systematically with attention to potential side effects.

  • Importance of understanding programming, training, and preparation for extinction.

Definition of Extinction

  • Extinction can be defined as:

    • Withholding or discontinuing reinforcement for behavior that was previously reinforced.

    • Reinforcement is responsible for behavior persistence; thus, cutting off reinforcement leads to extinction.

    • Example: A teacher stops scolding a disruptive student who was previously reinforced by the attention received from scolding.

Key Concepts of Extinction

  • Response Requirement: The behavior must occur for extinction to take effect; simply blocking a response does not equate to extinction.

  • Distinction from Punishment:

    • Extinction is not the same as punishment.

    • Punishment involves adding or removing consequences to reduce behavior (positive and negative punishment).

    • Extinction specifically involves withholding reinforcement, not adding or taking away stimuli.

Types of Extinction

  • Functional Extinction:

    • This type of extinction intervention is aligned with the function of the behavior.

    • Necessary to perform functional analyses to identify the behavior's function.

    • Understanding the function helps determine the specific reinforcement that must be withheld.

    • Examples of functions include:

    • Tangibles: Withholding tangible rewards to address behaviors seeking material items.

    • Escape: Preventing escape to address behaviors aimed at avoiding tasks or situations.

  • Procedural Extinction:

    • Ignoring the behavior without regard for its function.; generally less preferred.

Side Effects and Resistance to Extinction

  • Secondary Effects of Extinction:

    • Stakeholders, such as parents, must be informed about possible side effects prior to applying extinction.

    • Challenges with implementation include:

    • Extinction bursts: Temporary increases in behavior when extinction begins, indicating that extinction may be effective.

    • Emotional outbursts and aggression from previously reinforced individuals or clients.

    • Response variation: Clients may develop new behaviors to seek reinforcement when the original behavior no longer works.

    • Spontaneous Recovery:

      • The sudden re-emergence of an extinct behavior after it has been reduced.

    • Resurgence:

      • The return of the original behavior when a replacement behavior no longer earns reinforcement.

Planning for Extinction

  • Resistance to extinction can arise due to:

    • A long history of reinforcement making behavior change difficult.

    • The reinforcement being high-value to the individual.

    • The amount of effort required to engage in the behavior.

    • Previous exposure to extinction affecting expectations and behavior.

  • Behavior analysts must effectively communicate the potential challenges, including the possibility of longer duration and difficulty in extinction success.

Implementation of Extinction

  • Consistency is Key:

    • Reinforcement must be withheld every single time to ensure effective extinction.

    • Ideally, achieving a 100% consistency is preferred, with 95% being adequate; 70% is too low and can worsen behavior.

  • Collaboration with Stakeholders:

    • It is vital that all stakeholders involved are aware and on board with the extinction process.

    • Coordination ensures that the same reinforcement withholding tactics are employed consistently across various settings.

    • Behavior analysts must be available to explain, train, and support stakeholders during implementation.

Conclusion

  • Extinction is a powerful method for reducing problematic behavior in ABA.

  • It requires careful planning to address side effects and ensure all involved are prepared for challenges that may arise.

  • Behavior analysts must remain transparent about the process, explaining potential increases in targeted behavior and the importance of consistency in execution to stakeholders.

  • Extinction is best used in conjunction with reinforcing new, appropriate behaviors.
