What happens in the process of extinction?

In the process of extinction, the conditioned response is eliminated through the repeated presentation of the conditioned stimulus without the unconditioned stimulus. This process occurs in classical conditioning, where the association between the two stimuli is weakened over time. For example, if a dog is trained to salivate at the sound of a bell (the conditioned stimulus) by pairing it with food (the unconditioned stimulus), repeatedly presenting the bell without the food will eventually lead the dog to stop salivating in response to the bell. This demonstrates that the learned response diminishes as the reinforcement (the unconditioned stimulus) is removed, leading to the gradual weakening and eventual disappearance of the conditioned response.
