Carly used to be afraid of visits to her family doctor because she associated the sight of his waiting room with the pain of having a blood sample drawn. However, Carly's new doctor's lab worker is "painless," and the sight of the waiting room is no longer associated with pain. Consequently, Carly finds her fear of visits to her family doctor has disappeared. This illustrates the classical conditioning process known as___

Extinction

Explanation:

Extinction is a classical conditioning process which occur when a person or an individual manifest a behaviour due to some condition or situation in which such manifested behavior manifests begin to fade off because of non-reinforced conditioned response over time which is why extinction often occurs when a response is no longer been reinforced due to a discriminative stimulus or when the conditioned stimulus is been applied frequently without being paired with the unconditioned stimulus which lead to the learned behavior to occur less often and eventually stops altogether over time or decreasing or disappearing over time just as in the case of Carly.

Therefore the behaviour of Carly illustrates the classical conditioning process known as EXTINCTION.
