Extinction
In extinction, a previously conditioned stimulus is presented several times without the originally paired reinforcement until the conditioned response subsides. For example, a dog has learned that the ringing of a bell announces food (conditioned stimulus → conditioned salivation response). In extinction, the bell is now rung several times without food following. After a few repetitions, the dog stops drooling when the bell rings: the conditioned response subsides. This decrease in response can also be detected at the synaptic level, for example, by a reduction in neurotransmitter release.
