Answer:
extinction
Explanation:
Ivan Pavlov stated that behavior which is being conditioned with an outside unconditioned stimuli tends to extinct after the withdrawal of the unconditioned stimuli.
Extinction: It is defined as the deletion of formerly delivered unconditioned reinforcers or stimuli. However, this is also defined as the absence of an eventuality between reinforcer or response.
Example: In Pavlov's classic experiment- the dog was conditioned to salivate after hearing the sound of a bell whereas, In operant conditioning- extinction occurs after a response is no longer reinforced backing a particular stimulus.
