What is Extinction in Psychology
We introduce a core idea that explains how learned responses fade when reinforcement stops. This process helps us predict behavior change across therapy, classrooms, and daily habits.
We define the decline of conditioned responses as gradual, not instant. In learning, a response weakens when expected outcomes no longer appear.
We preview two routes: one for automatic reactions and one for voluntary acts. This helps readers link classic studies to real examples like Pavlov and Skinner, and to practical plans for habit work.
Finally, we set expectations for this ultimate guide. We will cover mechanisms, common pitfalls such as brief surges in behavior, and ways to reduce relapse with clear, usable steps.
Extinction in psychology: the core definition and why it matters for behavior change
We explain how a previously reliable response loses power when the payoff no longer arrives. That shift matters because it changes why someone acts the way they do. Extinction is a process that alters the reward structure that once kept behavior steady.
What “extinction occurs” really means
When extinction occurs, a response that once produced reinforcement no longer does. Over repeated opportunities the action weakens. This happens whether the cue no longer predicts an outcome or a reward is withheld.
How time and repeated non-reinforcement weaken learning
Time matters because the brain needs many trials to update expectations. With each non-reinforced trial the response drops a bit. Consistent non-reinforcement speeds the decline; sporadic rewards slow it and make behaviors last longer.
Why extinction does not erase earlier learning
Extinction often reflects new learning that competes with the old. The original memory can return, so relapse is possible. The practical result: consistent application of non-reinforcement yields more predictable decline.
| Context | What stops | Typical timecourse | Practical note |
|---|---|---|---|
| Classical conditioning | Unconditioned stimulus | Gradual | Repeat non-pairings |
| Operant conditioning | Reinforcement | Slow decline | Be consistent to reduce relapse |
| Everyday habits | Payoff removed | Varies with history | Well-established acts take longer |
How extinction works in classical conditioning
We trace how a simple cue that once predicted an event slowly loses its pull when the expected outcome stops arriving.
Conditioned stimulus vs. unconditioned stimulus and the conditioned response
In classical conditioning a conditioned stimulus (a neutral cue) comes to predict an unconditioned stimulus (an automatic trigger like food). Over time the conditioned response appears when the cue shows up.
If the conditioned stimulus repeats without the unconditioned stimulus, the conditioned response weakens. This follows basic research on cue–outcome updating.
Pavlov’s dog: sound, food, and the fading salivation response
Pavlov paired a sound with food until the dog salivated at the sound alone. During extinction the sound played without food and salivation fell across trials.
Fear conditioning examples: when a cue no longer predicts threat
Fear responses decline when a cue that once signaled danger is repeatedly experienced safely. This principle underpins exposure work for anxiety.
- Parts list: conditioned stimulus, unconditioned stimulus, conditioned response.
- Process: cue appears → expected event does not follow → response drops over repeated trials.
- Clinical note: repeated safe exposures support lasting change.
How extinction works in operant conditioning
When a learned action no longer earns a reward, the pattern of responding shifts in predictable ways. In operant conditioning this happens when reinforcement stops and a response no longer produces a consequence.
When a rewarded behavior stops paying off: reinforcement removal in action
We see an initial surge as the subject tries harder or varies the response. Frequency and intensity often spike before a steady decline follows.
Skinner’s lever-press discovery and the extinction curve
B. F. Skinner noted the first clear extinction curve when a pellet dispenser jammed and lever pressing fell in a patterned way. The curve helps us chart change instead of guessing if progress occurred.
Real-life example: a child’s attention-seeking behavior and planned ignoring
When a child’s misbehavior is maintained by attention, planned ignoring can remove that reward. If attention slips back after a bigger outburst, the decline stalls and the behavior may persist.
How discriminative stimuli and an extinction stimulus change responding
Discriminative stimuli signal when reinforcement is available. An extinction stimulus (SΔ) signals it is not. Detecting these cues lets us predict when behaviors will rise or fall and apply alternatives effectively.
What is Extinction in Psychology in everyday life
When the little gains that fuel a routine disappear, the routine often declines over repeated tries. We translate lab terms into practical steps so readers can recognize how habits fade at home, work, or school.

Habits and rewards: why behaviors fade when the payoff disappears
Many daily habits rely on tiny, repeatable payoffs. If a notification no longer feels rewarding, checking it can drop off after several unrewarded attempts.
Time and consistent non-reinforcement matter. The urge weakens across opportunities rather than vanishing instantly.
Conditioned taste aversion example: rebuilding tolerance through safe exposure
A food aversion often forms after nausea. Gradual, safe exposure — small tastes without illness — can reduce that aversive conditioned response over time.
We recommend pacing and safety: start small, track progress, and pair exposure with a calming routine. Replacing an old payoff with a healthier alternative helps the new pattern stick.
- Translate lab steps to daily routines.
- Remove the small rewards that keep a habit active.
- Use gradual exposure to rebuild tolerance safely.
The extinction curve: what we typically see before behavior decreases
We track the typical pattern of responding after reinforcement stops and explain why decline usually unfolds across trials rather than all at once.
Why the drop is gradual, not instant
Learning history shapes expectations. If a response paid off for a long time, the organism keeps testing the old rule before it gives up.
This cautious persistence makes the process slow. Each unrewarded trial nudges the response downward, so change appears as a curved decline.
What behavior longer looks like when a response is well established
Well-practiced routines can persist across many opportunities. In real settings, a habit may continue for weeks before showing clear reduction.
We call this behavior longer because the past payoff made the action reliable. Strong histories mean more trials are needed to shift the result.
How frequency and intensity shift during the process
Frequency often falls while intensity sometimes spikes briefly. For example, counts may drop but single events become louder or more extreme.
Track progress with simple measures: count occurrences, time durations, or rate intensity on a short scale. That helps us see the true trend despite temporary rebounds.
- Define the extinction curve: non-linear decline across time.
- Expect persistence when history is strong; plan for more trials.
- Measure frequency and intensity separately to capture real change.
Extinction burst, variability, and other “it got worse first” effects
We outline a short-lived escalation that often appears when reinforcement stops and the old pattern briefly spikes. This burst is a normal, predictable part of learning change.

Sudden surge before decline
An extinction burst describes a temporary rise in responses — more frequent attempts, higher intensity, or longer episodes — right after we remove the reward. The increase usually fades after repeated non-reinforced trials.
New strategies emerge
Extinction-induced variability means new behaviors show up as the person searches for another route to the same payoff. We often see novel attempts or shifted tactics before the original action drops.
Practical child-focused examples and tips
Common examples include a child’s tantrums that grow louder during planned ignoring, aggression that appears briefly, or unexpected classroom disruptions. If attention returns during the burst, the escalation gets reinforced.
- Stay consistent: don’t give the old reward during the burst.
- Reinforce alternatives: praise asking, waiting, or calm communication.
- Track frequency and intensity to monitor real progress.
| Effect | What to watch | Practical note |
|---|---|---|
| Burst | Spike in attempts | Ignore target, reinforce alternatives |
| Variability | New behaviors appear | Redirect and teach replacement skills |
| Outcome | Short-term worse, long-term decline | Consistency prevents accidental reinforcement |
Spontaneous recovery and relapse: why an extinct response can return
After a pause, a once-quiet reaction can reappear suddenly, surprising caregivers and therapists alike. Spontaneous recovery explains how a previously reduced response can pop back after some time without any new reward.
Recovery over time
We see spontaneous recovery when a response resurfaces after days or weeks. Extinction often adds new learning rather than erasing the old trace, so older memory can reemerge with little provocation.
Context and place triggers
A change of context or place often brings back a prior behavior. Different rooms, routines, or people can make older cues feel relevant again and prompt the response.
Stress, fear, and anxiety effects
High stress or strong emotion can revive fear responses even after clear progress. Anxiety raises arousal and makes earlier threat-learning more available, so relapses cluster around tense moments.
- View a brief return as a normal recovery event, not total failure.
- Use booster exposures across settings to widen generalization.
- Maintain consistency and avoid accidental reinforcement during a surprise return.
| Trigger | Likely effect | Action |
|---|---|---|
| Passage of time | Spontaneous recovery of response | Schedule refresh sessions |
| New context/place | Behavior returns in different setting | Practice across locations |
| Stress or fear | Sudden relapse of anxiety-linked response | Use calming routines and safe exposures |
Why some behaviors are harder to extinguish than others
Some patterns resist change because the original learning was irregular or intense. That history shapes how long a response stays active after we stop rewarding it.

Partial schedules and the persistence effect
Unpredictable payoffs teach organisms to keep trying. When rewards arrive only sometimes, the brain learns persistence. That makes decline slower and more frustrating when non-reinforcement begins.
Strength of prior conditioning
Longer training and bigger emotional stakes build stronger conditioned responses. Strong histories need more non-reinforced trials to shift behavior and often show greater early turbulence.
Habituation, attention, and exposure
Repeated, safe exposure can reduce attention to a cue and lower responsiveness. Habituation works alongside extinction-like change and helps explain why some signals lose power faster than others.
Individual differences: anxiety and children
Anxiety alters how quickly people update threat learning. Studies suggest some children habituate more slowly to sounds, slowing fear decline after exposures.
- Plan for longer timelines when training was long or intermittent.
- Use repeated exposure across settings to widen gains.
- Expect more variability early and rely on consistent practice.
| Factor | Effect | Practical step |
|---|---|---|
| Partial rewards | High persistence | Increase consistent non-reinforcement |
| Strong conditioning | Slower decline | Extend exposure trials |
| Anxiety | Slower habituation | Combine calming and exposure work |
Extinction in therapy, school, and behavior programs today
We outline how repeated, safe exposures and consistent withholding of rewards reshape learned fear and disruptive acts. This approach guides exposure therapy, classroom plans, and applied behavior analysis.
Exposure therapy and fear reduction
Exposure uses repeated, planned contact with feared cues without harm. Over time the fear response declines and patients build confidence through new experience.
For PTSD-related learning, persistent fear often reflects hard-to-change conditioned responses. Targeted exposure helps update threat predictions and reduce reactive responding.
Classroom and ABA applications
Teachers and therapists use attention extinction by withholding attention for attention-maintained behavior. They use escape extinction by preventing escape when demands trigger avoidance.
Functional assessment guides the choice. If we misidentify the maintaining reward, the plan can fail and behaviors may worsen.
Safety, ethics, and team consistency
Extinction should not stand alone for dangerous acts. We plan safety measures and avoid withholding essential communication, especially for nonverbal individuals.
Consistent follow-through across caregivers and staff prevents intermittent reinforcement, which otherwise strengthens the behavior.
- Assess function before applying non-reinforcement.
- Pair extinction with teaching of replacement skills.
- Document safety plans and align the team.
| Setting | Common targets | Key precaution |
|---|---|---|
| Clinical exposure | Fear responses, avoidance | Ensure safety; use gradual steps |
| Classroom / ABA | Attention-maintained or escape-maintained behaviors | Confirm function; teach alternatives |
| PTSD care | Persistent conditioned fear | Use trauma-informed protocols; monitor reactions |
Using extinction principles effectively without losing momentum
We outline a practical, stepwise approach to use extinction psychology without losing momentum.
First, identify the target behavior and the maintaining consequence. Then remove that reinforcement consistently while teaching and reinforcing a clear replacement behavior immediately.
Expect predictable spikes like extinction bursts and plan what we will do — and not do — during those moments. Tighten consistency across caregivers to avoid accidental intermittent reinforcement.
Track counts, duration, and context so we see the true process rather than react to single incidents. Schedule booster sessions to reduce spontaneous recovery and protect gains.
When fatigue or mixed messages happen, correct quickly and keep the plan. Success looks like durable change: fewer problem behaviors, better coping, and clearer goals for the responses we want to strengthen.
