What is extinction in classical conditioning?
In psychology, extinction refers to the gradual weakening of a conditioned response that results in the behavior decreasing or disappearing. In other words, the conditioned behavior eventually stops. For example, imagine that you taught your dog to shake hands. Over time, the trick became less interesting.
Does classical conditioning Show extinction?
Extinction occurs when the CS is repeatedly presented without the US, and the CR eventually disappears, although it may reappear later in a process known as spontaneous recovery.
What are extinction and spontaneous recovery in classical conditioning?
Extinction and Spontaneous Recovery With extinction, the behavior ceases when the conditioned stimulus is presented, or the behavior becomes sporadic when the stimulus is present. Spontaneous recovery can only happen after extinction and usually follows a rest period where no stimuli are presented.
How did Pavlov demonstrate extinction?
Pavlov found that after a two-hour rest period, the salivation response suddenly reappeared when the tone was presented. Essentially, the animals spontaneously recovered the response which was previously extinct.
What is extinction technique?
Extinction is a behavioral technique where you withhold reinforcement when the behavior occurs, so by definition you must know what the reinforcement is. Planned ignoring would only extinguish a behavior if the reinforcement was attention.
What are the principles of extinction?
Extinction procedures apply the “principle of extinction” which proposes that because behaviours occur for a reason – they get us things we want – if we stop getting what we want after we engage in a certain behaviour then that behaviour will eventually stop occurring because it no longer serves any purpose for us.
How does extinction occur?
Extinction happens when environmental factors or evolutionary problems cause a species to die out. The disappearance of species from Earth is ongoing, and rates have varied over time. A quarter of mammals is at risk of extinction, according to IUCN Red List estimates. To some extent, extinction is natural.
What can cause extinction?
CAUSES OF ANIMAL EXTINCTION
- Demographic and genetic phenomena.
- Destruction of wild habitats.
- Introduction of invasive species.
- Climate change.
- Hunting and illegal trafficking.
What is the difference between extinction and spontaneous recovery?
Extinction is used to describe the disappearance of an unconditioned or conditioned response, while spontaneous recovery refers to the reappearance of an unconditioned or conditioned response after a period of extinction.
What is extinction in psychology Pavlov?
The term “extinction” was first used by Ivan Pavlov in reference to his observation that the conditioned response to a cue that predicted food delivery decreased and eventually disappeared when food no longer followed the cue.
What is meant by extinction in learning?
Definition. Extinction learning refers to the gradual decrease in response to a conditioned stimulus that occurs when the stimulus is presented without reinforcement.
What are the forms of extinction?
Types of Extinction
- Escape maintained Extinction, this is where a child receives negative reinforcement.
- Extinction of Positively Reinforced Behaviors.
- Extinction Burst, you will see this shortly after the extinction procedure has been implemented, this is when the behavior gets worse before it gets better.
What factors influence extinction?
Natural Extinction Factors
- An asteroid or comet Impact event caused many of the dinosaurs to go extinct.
- Ice Ages have greately impacted the Cenozoic era.
- Predators naturally can cause extinction.
- Predators can cause extinction.
- Volcanic Eruptions have caused the greatest extinctions ever!
What are the types of extinction?
There are two types of extinction: background extinction, which is a natural part of evolution, and mass extinction, which typically means some form of catastrophic event (such as a volcano eruption or an asteroid hitting the Earth) has decimated plant and animal life.
Whats extinction means?
Definition of extinction 1 : the act of making extinct or causing to be extinguished. 2 : the condition or fact of being extinct or extinguished also : the process of becoming extinct extinction of a species. 3 : the process of eliminating or reducing a conditioned response by not reinforcing it.

What is extinction example?
The toy duck becomes the conditioned stimulus and the sister’s jump is the conditioned response. If the brother continues to scare her with the duck without the loud sound, the sister may get used to the duck over some time and it will no longer make her jump which is an example of extinction.
What is an example of extinction in the classroom?
For example, the child who disrupts the class may become louder or more disruptive in an attempt to elicit a response when the class ignores the behavior. This exaggerated attempt at getting a response is referred to as an extinction burst.
