What happens when a behavior that used to “work” suddenly stops producing the same result?
That question sits at the heart of extinction in Applied Behavior Analysis, or ABA. Extinction is not the same as ignoring, punishment, or just denying a child something they want, but those are all often used to describe what extinction is. Extinction is a function-based, planned, data-driven and typically accompanied by the teaching of a safer and more useful function.
Parents also need to be aware that behaviour is not always reduced in a gradual manner. Those details matter for safety. Families must have an understanding prior to the onset of a plan.
This guide provides an explanation of what extinction in ABA therapy is, how reinforcement helps to maintain behavior, the primary types of extinction, what extinction bursts are, and how qualified ABA teams approach safety, ethics, measurement, and family participation.
What Is Extinction in ABA Therapy
Extinction in ABA is the discontinuation of the reinforcement that has been maintaining a previously reinforced behavior. If this behavior is not seen as effective anymore because it no longer brings the desired result, then it may diminish over time.
One of the important things to remember is that extinction alters the connection between the behavior and the reinforcer. It’s not about denying a child care, comfort, communication and all their preferred experiences. The steps are dictated by the reason for the behavior.
How Reinforcement Maintains Behavior
Repeated behavior often has a history of producing a meaningful consequence. A child can get attention, access to an item, get out of a challenging task, or sensory stimulation after a behavior. This consequence then increases the likelihood of the behavior occurring in similar situations, thus providing reinforcement for the behavior.
A simple pattern is
- Situation or trigger
- Behavior
- Reinforcing consequence
- Greater likelihood of the behavior occurring again
Think about a child who cries when doing homework and the homework is taken away. Escape may reinforce crying if its removal is consistent following a cry.
Types of Extinction in ABA
The best way to know the kinds of extinction in ABA is by behavioral function. The basic principle involved in searches for functional extinction ABA is to determine what the behavior is being maintained by, and then alter the reinforcement contingency.
Attention Extinction
When social attention is a maintaining reinforcer, attention extinction can be used. The target behavior no longer gets the attention that was previously reinforcing it and attention is now given to appropriate communication.
Escape Extinction in ABA
Escape extinction ABA procedures address behavior maintained by escaping or delaying a demand, task, or situation. The behavior is no longer associated with the escape. Clinically planned demands are essential as blind continuing can lead to distress or safety issues.
Tangible or Access Extinction
Tangible extinction occurs when the behaviour has previously gained access to a preferred item, activity or event. The target behavior ceases production of that access and an appropriate request or other replacement response is reinforced.
Sensory Extinction in ABA
Sensory extinction ABA procedures involve automatically reinforced behaviors, in which the reinforcing effect is achieved by the behavior itself, and not by another person. This makes assessment and treatment much more complicated.
Extinction by Function at a Glance
| Function | What May Reinforce the Behavior | What Changes | Possible Replacement Skill |
| Attention | Social reactions | Target behavior no longer produces maintaining attention | Requesting attention |
| Escape | Task removal or delay | Target behavior no longer produces the same escape | Requesting a break |
| Tangible | Preferred item or activity | Target behavior no longer produces access | Appropriate requesting |
| Automatic | Sensory consequence | Relevant sensory contingency may be altered when appropriate | Safe, functionally relevant alternative |
Extinction Is Not the Same as Ignoring or Punishment
Planned ignoring is one of the many extinction procedures and is appropriate when the behaviour is being reinforced by attention. Ignoring does not correct the correct function if the behavior is being maintained through escape or acquisition of an item and can result in the same reinforcement pattern persisting.
Punishment is also different. Extinction involves stopping a previously reinforced response, punishment involves adding an aversive consequence to reduce a future response. The focus of clinical planning should be on function, positive reinforcement, teaching a useful skill and reducing unnecessary risk.
Why an FBA Comes Before Extinction
A behavior plan should not be made up on the fly. Functional assessment (which can involve a Functional Behavior Assessment or FBA) assists a clinical team to identify the target behavior, what happens before and after the behavior, likely maintaining variables, and the type of intervention to match to the function.
Useful baseline information may include
- Frequency or rate
- Duration
- Intensity when clinically relevant
- Settings and people present
- Antecedents and consequences
- Existing communication or replacement skills
The BACB Ethics Code requires behavior-change interventions to be assessment-based, scientifically supported, and continually evaluated.
How Extinction Is Implemented in ABA Therapy
Professional implementation is more than simply “not giving in.” A function-based plan is a sequence of events that will help to keep the learner safe and explain the new contingency.
Identify the target behavior in an observable manner.
- Assess its likely function.
- Determine the maintaining reinforcer.
- Choose an extinction element that matches the function as appropriate.
- Choose and teach a replacement skill.
- Schedule reinforcement, caregiver staff training and safety plans.
- Follow the written plan in all appropriate environments.
- Gather data and adjust plan as outcomes are not satisfactory.
This is not a self-directed aggression, self-injurious behavior, elopement, feeding, or other high-risk behavior protocol.
What Is an Extinction Burst in ABA
Extinction burst in ABA is a temporary rise in some aspect of responding following the removal of the reinforcer for a behavior. Extinction bursts may involve increased frequency, duration, intensity, or variations of the response. They can happen but they don’t have to happen.
What the Research Actually Shows
A 2024 Journal of Applied Behavior Analysis record review examined 108 clinical cases and found extinction bursts in 24% of cases. Following introduction of extinction, burst magnitude declined across sessions but no consistent relationship between bursting and behavioral function, topography or treatment components.
An earlier 1995 analysis of 113 extinction data sets also reported bursts in 24% of cases. Bursting occurred in 12% of cases when extinction was combined with alternative procedures versus 36% when extinction was used alone. These findings contradict the widely held assumption that behaviour will “always get worse before getting better.”
A Burst Does Not Prove Treatment Is Working
A burst isn’t a success criterion in itself. An absence of its presence does not amount to a failure of an intervention and a presence does not constitute that the function was identified. Choices should be made based upon the complete data pattern and safety, replacement-skill progress, and meaningful outcomes.
Why Behavior Can Return After Extinction
Extinction does not necessarily erase prior learning. Discarded behavior may return later in time, with a change in context, or a change in reinforcement.
- Spontaneous recovery involves reacting briefly, followed by a period of no reaction.
- Renewal occurs when behavior comes back when the context changes.
- Resurgence may occur when a behaviour, that has previously been reduced, reappears when reinforcement of the alternative behaviour is reduced.
A 2026 article in Nature Reviews Psychology pointed to the amplification effects (extinction bursts and increased behavioural variability) and the relapse effects (spontaneous recovery, renewal and reinstatement).
Why Replacement Skills Matter
Extinction communicates to the learner that a response is no longer effective; however, good treatment will also teach an effective response. Differential Reinforcement of Alternative Behavior (DRA) can increase the likelihood of a safer or more functional response and Functional Communication Training (FCT) can provide the training to access the same relevant outcome.
Useful replacement skills may include
- Asking for attention
- Requesting a break
- Asking for an item
- Requesting help
- Communicating discomfort or a need
A recent meta-analysis synthesized 34 FCT studies involving 79 autistic children ages 2 to 8. It also found moderate-to-large effect sizes for decreasing challenging behavior and large effect sizes for increasing replacement behavior, but concluded that there was a need for more research on maintenance, generalization, treatment fidelity, and parent training.
Why Consistency Matters During Extinction
The transition from one reinforcer to another may be confusing to a learner when not implemented consistently. If that behavior still results in that reinforcer every so often, then the behavior can: continue or be more persistent.
Consistency includes:
- Following the written plan across relevant settings
- Ensuring caregivers, teachers, and therapists respond appropriately
- Reinforcing the replacement skill as planned
- Monitoring whether the previous reinforcer is still being delivered
- Regularly checking data and fidelity of the treatment.
Reinforcement history also influences extinction effects of behavior. The intermittent or unpredictable reinforcement may make behaviors harder to change than behaviors that are reinforced consistently. This means that ABA teams gather data in multiple settings, offer training for the caregivers, and modify the plan if implementation or outcomes are not sufficient.
How Progress Is Measured
ABA teams rely on data to decide if a plan is working, if it needs to be adjusted, or if it should be terminated. They can be number, time, clinically significant intensity, replacement skills, or patterns in settings.
Progress should be measured over time and not from one challenging session. The BACB Ethics Code directs behavior analysts to collect appropriate data and continually evaluate behavior-change interventions, taking corrective action when desired outcomes are not being achieved.
Safety and Ethical Best Practices
Extinction is not an automatic response to a behavior that is hard. Ethical planning considers the learner’s dignity, preferences, communication, health, safety, family priorities and risks and benefits of the available approaches.
When engaging in behavior, there is an extra need for caution:
- Aggression or self-injury
- Elopement or other serious safety risks
- Significant escalation
- Possible pain, illness, or biological variables
- Automatically reinforced behavior
- Environments where the plan cannot be implemented reliably
The BACB Ethics Code emphasizes assessment, scientific evidence, positive reinforcement, risk minimization, informed consent when applicable, data collection, and ongoing evaluation. The BACB noted that as of July 1, 2026, there are 85,587 BCBAs and 260,174 RBTs, further emphasizing the size of a field where professional and ethical standards are important.
What Parents and Caregivers Should Know
Parents can be involved in an effective way without being behavior analysts. They should know the purpose of the team, what skill they are looking for the team to address, what data they are gathering and what changes would indicate a clinical review.
Helpful questions include
- What is the meaning or purpose of this behavior?
- What will my child learn to do instead?
- How will safety be protected?
- How will we know the plan is helping?

Function-Based Extinction ABA Examples
Escape-Maintained Behavior:
A learner cries when worksheets begin. The team finishes small jobs, models how to request a break and teaches communication rather than allow crying to be a signal to end the activity.
Attention-Maintained Behavior:
Child calls out to get adult’s attention. Caregivers minimize attention for shouting, teach an appropriate attention request, and immediately reinforce calm communication with social interaction.
Tangible-Maintained Behavior:
A learner grabs toys when access is denied. The team does not give the toy after grabbing, and teaches a request for the toy and reinforces it with short accessible play.
Individualized ABA Support for Your Child and Family
Extinction may be a part of certain behaviour plans but it is just one of a wide and varied range of possible behaviours within a more individualised plan of ABA. While there is no evidence of extinction or any individual procedure being effective with every child, one industry projection of the ABA market states that it will increase from approximately $4 billion in 2023 to $6 billion by 2032.

To discuss your child’s needs and available services, Call (747) 250-8494 or email info@almabehavioralsolutions.com. The team does not assume that extinction is the appropriate intervention, but can assist your family in determining the next steps.
Frequently Asked Questions About Extinction in ABA
How Long Does Extinction Take in ABA Therapy
There is no standard timeline. Change is dependent on the reinforcement history, function, setting, treatment integrity, replacement skills and individual learning. Clinicians use ongoing data rather than promising a fixed number of sessions.
How Long Can an Extinction Burst Last
No evidence-based universal duration applies to all learners. The burst can be short or can last over several opportunities. The course should be monitored by data, and not in terms of timeline, but rather of safety and clinical reassessment.
What Happens if Behavior Does Not Decrease During Extinction
The clinical team should reconsider than just up the intensity of the procedure. Possible issues include an incorrect function hypothesis, uncontrolled reinforcement, implementation problems, changing conditions, or a need for a different intervention approach.
Is Extinction the Same as Negative Reinforcement
No, negative reinforcement would increase future behavior because something bad would be removed or avoided following the response. Extinction decreases the behavior-reinforcer relationship by withholding the consequence that has been maintaining the behavior.
Can Parents Use Extinction Strategies at Home
Parents can be involved in a professionally developed plan, but parents should never attempt to handle complex or risky behavior through extinction. Caregiver coaching supports families to receive information about the function, replacement skill, training plan, safety protocols, and data.
