Welcome to the world of Applied Behavior Analysis (ABA)! If you’ve heard the term “extinction” used in this context, you might be wondering what it means. It’s not as harsh as it sounds. In ABA, extinction is a thoughtful and strategic approach used by a behavior analyst to help reduce challenging behaviors. It’s about changing our reactions to guide individuals toward more positive actions, moving away from punishment and toward a more constructive path of learning and development.
Understanding Extinction in Applied Behavior Analysis (ABA)
At its core, extinction in ABA refers to the gradual fading away of a behavior when it is no longer reinforced. Think of it as a behavior that runs out of fuel. If a specific action previously resulted in a desired outcome, like getting attention, extinction involves removing that outcome.
Over time, without the reinforcement, the behavior is less likely to occur. It’s a fundamental concept in behavior analysis, but it’s important to be prepared for an initial “extinction burst,” where the behavior might get worse before it gets better. Now, let’s explore what this principle truly involves and how it stands apart from other techniques.
Definition and Key Principles of Extinction
The principle of extinction is straightforward: you identify what reinforces a behavior and then stop providing that reinforcement. When a previously reinforced behavior no longer produces the expected consequence, its frequency will decrease until it eventually stops. This isn’t about punishing the individual but rather breaking the connection between the action and the reward.
A key aspect to understand is the “extinction burst.” When you first start an extinction procedure, you might see a temporary increase in the behavior. For example, if a child’s disruptive comments were previously met with laughter from classmates (a form of reinforcement), ignoring the comments might initially cause the child to become louder or more disruptive to get the reaction they are used to.
This escalation is a predictable part of the process and a sign that the procedure is beginning to work. It’s crucial for caregivers and therapists to remain consistent during this phase to ensure the behavior ultimately fades away.
How Extinction Differs From Other ABA Techniques
How does extinction differ from other behavioral modification techniques? While several strategies exist within ABA, extinction is unique. It is not punishment, which involves adding an adverse consequence to decrease a behavior. Instead, extinction is the removal of a positive consequence.
It also differs from simply ignoring someone. While ignoring can be part of an extinction plan, the technique itself is a systematic process based on a functional assessment of the behavior. It’s a planned withdrawal of a specific reinforcer.
Furthermore, it is often used alongside other techniques like differential reinforcement. In differential reinforcement, you might use extinction for a problem behavior while simultaneously providing reinforcement for an appropriate, alternative behavior. This combined approach not only reduces the undesirable action but also teaches a positive replacement skill.
The Role of Reinforcement in Extinction Procedures
Reinforcement is the engine that drives behavior, and understanding its role is essential to making an extinction procedure work. Every action has a consequence, and if that consequence is rewarding, the action is more likely to be repeated. Reinforcement can be positive (adding something desirable) or negative (removing something undesirable).
To effectively use extinction, you must first identify what is reinforcing the behavior you want to eliminate. Is it attention? Access to a favorite toy? Escape from a task? Once you pinpoint the specific reinforcer, you can systematically withhold it. Let’s look closer at why reinforcement is so vital in ABA and how withholding it leads to change.
Why Reinforcement Is Important in ABA
In ABA, reinforcement is a cornerstone for teaching and encouraging positive behaviors. It’s the process of delivering a consequence immediately after a behavior that increases the likelihood of that behavior happening again. A behavior analyst uses reinforcement to build skills and motivate individuals.
Positive reinforcement involves adding something pleasant, like praise or a token, after a desired action. This makes the individual want to repeat the action. While negative reinforcement is also a concept, ABA therapy focuses heavily on using positive reinforcement to foster a supportive and encouraging learning environment.
This focus is why extinction is rarely used in isolation. Can extinction be combined with other ABA strategies? Absolutely. It is most effective when paired with the reinforcement of an alternative, more appropriate behavior. This dual approach helps the individual learn what to do instead of just what not to do.
How Withholding Reinforcement Leads to Extinction
Withholding reinforcement is the active ingredient in an extinction procedure. When a behavior that was previously reinforced no longer gets the expected payoff, the motivation to perform it diminishes. The link between the action and the reward is broken. An ABA therapist works to ensure this process is consistent.
For example, if a child disrupts a class to get attention from the teacher and peers, withholding that social attention is the key to extinction. Over time, the child learns that the disruptive behavior is no longer effective.
What does withholding reinforcement look like in practice? An ABA therapist or parent might be instructed to:
- Avoid making eye contact
- Refrain from any verbal comments or reactions
- Withhold physical contact
- Deny access to specific items or activities that the behavior previously earned
Identifying Behaviors Appropriate for Extinction
Before implementing an extinction plan, it is critical to determine if the strategy is appropriate for the specific behavior. Extinction should not be used for dangerous or aggressive behaviors that could cause self-injury or harm to others, as the initial extinction burst could make the situation unsafe.
The first step is always a functional assessment conducted by a professional. This assessment helps to understand the “why” behind the undesirable behavior—what function it serves for the individual. Based on this information, a practitioner can decide if extinction is a safe and ethical choice. We will now look at common behaviors targeted and how they are assessed.
Common Target Behaviors in ABA Therapy
In ABA therapy, extinction is often applied to a range of common problem behaviors that are challenging but not severely dangerous. The goal is to reduce actions that interfere with learning, social skills, and daily functioning.
Some of these behaviors include:
- Tantrums or crying to get an item or attention
- Inappropriate social behaviors like interrupting
- Minor disruptive actions like making noises in class
- Mildly aggressive actions like a pinch
For instance, consider a child who pinches a classmate during circle time. An ABA therapist might use extinction by removing the child from the environment each time the pinch occurs, without verbal reaction. At the same time, the therapist would provide praise (positive reinforcement) whenever the child sits appropriately without pinching, thereby teaching a replacement behavior.
How Practitioners Assess Which Behaviors to Address
How do practitioners assess which behaviors to address? The process begins with a comprehensive functional assessment. A Board Certified Behavior Analyst (BCBA) will observe the individual, collect data, and talk to caregivers to understand the patterns surrounding the behavior. The goal is to determine the function—the reason the behavior is occurring.
This assessment is crucial for creating an effective intervention. By identifying the function, the behavior analyst can ensure that the extinction plan correctly targets the specific reinforcement that is maintaining the behavior. The assessment also helps in selecting a suitable replacement behavior to teach.
The analysis can be summarized to create a clear plan.
| Behavior | Potential Function | Replacement Behavior |
|---|---|---|
| Yelling in class | To get attention | Raising hand to speak |
| Throwing toys | To escape a task | Asking for a break |
| Grabbing items | To get a desired toy | Pointing or asking for it |
Steps for Effectively Implementing Extinction
Successfully implementing extinction is more than just deciding to ignore a behavior. It requires a structured extinction plan and unwavering consistency from everyone involved. Without a clear procedure, the efforts can be ineffective and may even accidentally strengthen the behavior.
An effective plan anticipates challenges, such as the extinction burst, and outlines how to respond. It also incorporates reinforcement for positive behaviors, making the change process smoother and more successful. The following sections will detail how to prepare for this process and what to do once it’s underway.
Preparing for the Extinction Process
Thorough preparation is the key to a successful extinction plan. The first step involves a behavior analyst creating a detailed, written plan. This document should clearly identify the target behavior and the specific reinforcement that will be withheld.
This plan must be shared with everyone who interacts with the individual—parents, teachers, and other therapists. Consistency is non-negotiable. If one person continues to provide reinforcement while others withhold it, the behavior will persist. Everyone must be on the same page and committed to following the procedure exactly as written.
A critical part of preparing is planning for the extinction burst. The team should create a safety plan in case the behavior escalates significantly. This ensures that the process can be managed safely and effectively without giving in and accidentally reinforcing the worsened behavior.
Monitoring and Adjusting During Extinction
Once an extinction procedure is in place, continuous monitoring is essential to track its effects. A practitioner will collect data on the behavior to see if the plan is working. This data helps answer important questions about the intervention’s success.
Are you seeing a decrease in the behavior over time? The data will show trends in the behavior’s frequency, duration, and intensity. This objective information is far more reliable than just a general feeling about whether things are getting better. Monitoring allows the team to make informed decisions.
Based on the data, the ABA therapist can make adjustments to the plan. Important factors to watch for include:
- The initial extinction burst and its severity
- The overall rate of decrease in the behavior
- Signs of spontaneous recovery, where the behavior briefly reappears after a period of absence
- The individual’s success in using the replacement behavior
Conclusion
In summary, understanding extinction within the realm of Applied Behavior Analysis is crucial for effective therapy and behavior modification. By differentiating extinction from other techniques and recognizing the importance of reinforcement, practitioners can better identify appropriate behaviors for intervention. Implementing extinction requires careful preparation and ongoing monitoring to ensure success. Remember, consistency is key when applying these principles, as they help shape desired behaviors over time.

Frequently Asked Questions
What is an extinction burst in ABA?
An extinction burst is a common and predictable part of an extinction procedure. It refers to a temporary increase in the frequency, intensity, or duration of the previously reinforced behavior right after reinforcement is withdrawn. An ABA therapist anticipates this burst and sees it as a sign the plan is starting to work.
Can extinction be combined with other ABA strategies?
Yes, and it is highly recommended. Extinction is most effective when included in an extinction plan that also uses strategies like differential reinforcement. This involves withholding reinforcement for the problem behavior while actively providing reinforcement for a positive replacement behavior, which helps the individual learn what to do instead.
How does extinction differ from other behavioral modification techniques?
Extinction specifically involves withholding the reinforcement that was maintaining a behavior. This differs from punishment, which adds an unpleasant consequence. It is also more systematic than simply ignoring, as it is based on a functional behavior analysis and is part of a structured plan that often includes reinforcement for other behaviors.
