In psychology, this concept is called extinction, and it is defined as the gradual weakening of a conditioned response resulting in a behavior stopping, or going extinct, over time.
What’s an example of extinction in psychology?
For example, imagine that you taught your dog to shake hands. Over time, the trick became less interesting. You stop rewarding the behavior and eventually stop asking your dog to shake. Eventually, the response becomes extinct, and your dog no longer displays the behavior.
What is extinction in psychology class 11?
The process of unlearning a learned response because of the removal of the aspect of the environment that originally caused the learning is termed as extinction. Extinction is sometimes slowed because of spontaneous recovery and external disinheriting.
What is a simple definition of extinction?
/ɪkˈstɪŋk.ʃən/ C1. a situation in which something no longer exists: The extinction of the dinosaurs occurred millions of years ago. Many species of plants and animals are in danger of/threatened with extinction (= being destroyed so that they no longer exist).

What causes extinction in psychology?
Extinction in classical conditioning and in operant conditioning (explained later) is the decrease or disappearance of the conditioned response when the unconditioned stimulus is no longer presented with the conditioned stimuli.

What is extinction and what causes it?
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 are the two main reasons for extinction?
Species become endangered for two main reasons: loss of habitat and loss of genetic variation. A loss of habitat can happen naturally. Dinosaurs, for instance, lost their habitat about 65 million years ago.
What are 3 human causes of extinction?
Causes of Extinction
- Exotic species introduced by humans into new habitats.
- Over-harvesting of fish, trees, and other organisms.
- Global climate change, largely due to the burning of fossil fuels.
- Pollution, which adds chemicals, heat, and noise to the environment beyond its capacity to absorb them.
What are the effects of extinction?
As species go extinct, they are taken out of the food chain. Animals that ate the newly-extinct species have to find new food sources or starve. This can damage the populations of other plants or animals. Furthermore, if a predator goes extinct, its prey’s population can proliferate, unbalancing local ecosystems.
What human activity causes extinction?
Over the past 50 years, global biodiversity loss has primarily been driven by activities like the clearing of forests for farmland, the expansion of roads and cities, logging, hunting, overfishing, water pollution and the transport of invasive species around the globe.
Why is extinction a problem?
Each time a species goes extinct, the world around us unravels a bit. The consequences are profound, not just in those places and for those species but for all of us. These are tangible consequential losses, such as crop pollination and water purification, but also spiritual and cultural ones.
What factors influence extinction?
To date, the most significant causes of extinctions are habitat loss, introduction of exotic species, and overharvesting. Climate change is predicted to be a significant cause of extinctions in the coming century. Habitat loss occurs through deforestation, damming of rivers, and other activities.
What is the principle 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 can we prevent extinction in psychology?
Therefore, you can prevent extinction by continually introducing the behavior to the person being conditioned without taking any breaks from the behavior. Eventually, after multiple exposure to the behavior, the person will then form a habit, and the behavior will continue.
