A child begins throwing themselves on the floor and screaming when he or she is ready to leave. Before, that would result in the therapist or parent picking the child up and leaving.
What is an example of extinction in the classroom?
Extinction is the discontinuing of reinforcement for a previously reinforced behavior. Example: The teacher no longer gives attention (which was reinforcing) to a student that talks out during instruction.
What does extinction mean in psychology?
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 is extinction psychology quizlet?
extinction. the diminishing of a conditioned response; occurs in classical conditioning when an unconditioned stimulus (US) does not follow a conditioned stimulus (CS); occurs in operant conditioning when a response is no longer reinforced. ( Myers Psychology 8e p. 319)

What does extinction mean for humans?
Human extinction, also known as omnicide, is the hypothetical end of the human species due to either natural causes such as population decline from sub-replacement fertility, an asteroid impact, or large-scale volcanism, or to anthropogenic (human) causes.
What are the 4 ways humans cause 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 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.
What human activities cause extinction?
The main modern causes of extinction are the loss and degradation of habitat (mainly deforestation), over exploitation (hunting, overfishing), invasive species, climate change, and nitrogen pollution.
What is a simple definition of extinction?
extinction, in biology, the dying out or extermination of a species.
What is fear extinction in psychology?
Fear extinction is defined as a decline in conditioned fear responses (CRs) following nonreinforced exposure to a feared conditioned stimulus (CS).
What is extinction in anxiety?
The discovery of extinction learning provided the basis for exposure therapy. Exposure therapy works by exposing patients to a feared thing (i.e., animal, object, or situation) until the fear response to that thing is extinguished.
Is extinction the same as forgetting?
What is the difference between forgetting and operant extinction? Forgetting: a behaviour is weakened as a function of time following its last occurrence. Operant extinction: weakens behaviour as a result of being emitted without being reinforced.
What is extinction in memory?
Memory extinction is a process in which a conditioned response gradually diminishes over time as an animal learns to uncouple a response from a stimulus (9). With contextual fear, extinction occurs when the mouse is placed into the context without shock after training.
What are the 5 types of extinction?
Top Five Extinctions
- Ordovician-silurian Extinction: 440 million years ago.
- Devonian Extinction: 365 million years ago.
- Permian-triassic Extinction: 250 million years ago.
- Triassic-jurassic Extinction: 210 million years ago.
- Cretaceous-tertiary Extinction: 65 Million Years Ago.
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 4 ways humans cause 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 3 ways that extinction could occur?
Possible reasons for extinction include:
- Climate change.
- Competition.
- Introduction of species.
- Hunting by Humans.
- Degradation and loss of habitats.
What causes extinction the most?
Destruction of Habitat – It is currently the biggest cause of current extinctions. Deforestation has killed off more species than we can count. Whole ecosystems live in our forests. It is predicted that all our rainforest can disappear in the next 100 years if we cannot stop deforestation.
What are the types of extinction?
There are two main types of extinction: Mass extinction and background extinction.
- Mass extinction has only occurred five times in history.
- Background extinctions take place over a longer period of time and are considered a more natural extinction rate.
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.
