Operant Extinction
Responding that meets the reinforcement contingency no longer produces the reinforcer falling to baseline levels. Responding decreases or stops completely.
Two Component (Procedure and Effect on Behavior)
Effects on Behavior By Operant Conditioning
Increase in Emotional Responses
Temporarily Increasing Behaviors
Increase Variability
Operant Extinction (SR+) (Positive Reinforcement)
The addition of a stimulus that previously reinforced behavior is withheld. Previously reinforced behavior no longer results in desired stimulus, leading to decreased behavior over time.
Ex: A child screams in a grocery store to get a toy. Every time, the parents give them in and buy them a toy. As soon as the parents stop giving them the toy, the child starts screaming, but over time, the screaming stops.
Operant Extinction (SR-) (Negative Reinforcement)
Escape Extinction (Removal of a stimulus that previously reinforced behavior is no longer removed) (Behavior no longer allows the individual to escape or avoid an aversive stimulus, leading to decrease in behavior over time)
Ex: The dog barks when its owner tries to put on its leash for a walk. The owner stops trying to put the dog on a leash when the dog barks. Eventually, the dog stops barking when the dog tries to put on its leash.
Useful for Us to Have an Idea of How Long Process Happens for Several Reasons
Extinction can be hard to implement.
Extinction has side effects.
Two Factors Influencing How Long Extinction Takes to Be Effective
1.
2.
- Reinforcement Rate (How often reinforcement is delivered contingent on a behavior)
- Motivation (More deprived you are of a reinforcer more likely you persist when you contact extinction)
Reinforcement Rate
Faster or Slower Extinction
(Behavior that contacts reinforcement less frequently is more resistant to extinction)
If behavior is reinforced each time it occurs > Faster extinction
If behavior is reinforced less frequently > Slower extinction
Partial Reinforcement Extinction Effect (PREE)
Explains the relationship between prior reinforcement and how quickly extinction takes to work. Takes longer for behavior to decrease to baseline levels.
Ex: A dog is taught to sit on command, and when the dog does this, the owner sometimes gives the dog a treat. However, the owner decides to stop giving the dog treats on command, so the dog that was always rewarded decides to sit on command for longer periods of time than the dog that was never rewarded.
Spontaneous Recovery
Spontaneous recovery occurs when an organism that has previously experienced extinction. After some time has passed, the organism engages in the behavior again.
Happens with Pavlovian and Operant Conditioning
Spontaneous Recovery Example
A dog is conditioned to salivate when it hears a bell because the bell has been repeatedly paired with food. During extinction, the bell is presented without food, and the dog stops salivating. However, days later, the bell rings with no food, and the dog suddenly salivates again.
Extinction-Induced Emotional Behavior
Contact with extinction often induces emotional responses. Emotional reactions that occur when reinforced behavior no longer produces expected reinforcement.
Ex: A child regularly gets candy from a vending machine. One day, the machine takes their money but doesn’t give them candy, so the child yells and hits the machine.
Extinction Burst
A temporary increase in the rate, magnitude, or duration of a previously reinforced response. Behavior immediately after extinction.
Ex: A child who gets candy by complaining is no longer given candy. Thus, the child complains louder and more frequently in the beginning before the behavior decreases.
Extinction-Induced Variability
An increase in the variety of operant response topographies following extinction. Individual starts trying different forms of behavior after original behavior no longer produces reinforcement.
Ex: A dog is trained to paw a bell to get treats. Once the treat is no longer given, the dog may try barking or using its nose to get the treat instead.
Extinction-Induced Resurgence
When one operant behavior is extinguished, other behaviors that were previously reinforced are emitted again.
Ex: A child is taught to say “please” instead of “complaining” when getting a toy. After a while, saying “please” no longer gets the child a toy. Thus, the child starts complaining again even when the behavior is reduced.
Functional Analysis of Behavior
A brief experiment in which consequences are turned on and off for a specific target behavior.
Scientific method used to determine if problem behavior is an operant and identify the reinforcer that maintains that operant.
Automatic Reinforcement
A consequence that is directly produced by the response – it is not provided by someone else – and which increases the behavior above a no-reinforcer baseline.
Ex: A student listens to music through headphones while doing homework. Nothing is gained, but the student finds the music enjoyable, which helps the student stay focused.
Differential Reinforcement
Procedure in which a previously reinforced behavior is placed on extinction while a second behavior is reinforced.
Provide greater reinforcement, along at least one dimension, contingent on the occurrence of one form or type of behavior, while minimizing reinforcement for another form or type of behavior.
Differential Reinforcement of Incompatible Behavior (DRI)
Reinforcement of a response that is incompatible with the target behavior.
Example: The student runs around the classroom, and the teacher reinforces the student only when sitting. The teacher doesn’t reinforce or respond neutrally when the student runs.
Differential Reinforcement of Alternative Behavior (DRA)
Reinforced response can be any adaptive behavior. Reinforce an appropriate and alternative behavior that serves the same function as the problem behavior while placing the problem behavior on extinction.
Ex: A child screams to get a toy, so the child is taught to ask for the toy politely. Screaming is ignored, but asking nicely gets them the toy.
Differential Reinforcement of Other Behavior (DRO)
The absence of problem behavior is reinforced at a pre-specified interval of time. Any other behavior is reinforced. Reinforce absence of problem behavior during specified period.
Example: Child bites their hand. Every 5 minutes, the child goes without biting, and they earn a reward.
Differential Reinforcement of Variability
Unique contingency in which responses, or patterns of reactions, that have either never been emitted before or haven’t been emitted in some times are reinforced, and repetition of recent response topographies are extinguished.
Example: The child plays with the same toy in the same way repeatedly. The therapist rewards the child when the child tries a new toy or a new way of playing.
Differential Reinforcement of High-Rate Behavior (DRH)
Reinforcement of lots of responding.
Example: Lever press has to occur at least 40 times per minute for reinforcer to be delivered.
Differential Reinforcement of Low-Rate Behavior (DRL)
Reinforcement of slow responding.
Example: Lever press has to occur less than 40 times per minute for reinforcer to be delivered.
Primary Reinforcers (Unconditioned Reinforcers)
Consequences that function as reinforcers without any prior learning because they are important to individual’s and/or species survival (phylogenic origin). Naturally reinforcing fulfilling basic biological needs and don’t require learning.
