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.

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 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.

- Introduction of invasive species.
- Climate change.
- Hunting and illegal trafficking.
What are the 7 causes of extinction?
Extinction occurs when species are diminished because of environmental forces (habitat fragmentation, global change, natural disaster, overexploitation of species for human use) or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers).
What are the 4 major 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.

- Climate Change.
- Disease.
- Loss of habitat.
- Lack of Genetic Diversity.
- Better Adapted Competition.
- Pollution.
How do we prevent extinction?
Scientists tell us the best way to protect endangered species is to protect the special places where they live. Wildlife must have places to find food, shelter and raise their young. Logging, oil and gas drilling, over-grazing and development all result habitat destruction.
Is extinction caused by humans?
The biggest threats to our planet’s species are humans. Our world’s population is increasing by millions each year. All these people are using more and more resources, leaving fewer resources for Earth’s other species.
