Pavlovian and Operant Conditioning
An antecedent stimulus can be linked to multiple consequences so it may serve both as a condition (Pavlovian conditioning) or a discriminative stimulus (operant stimulation). Consider the example of someone who is conditioned to recognize the sound of the bell by rewarding them with food. Pavlovian conditioning teaches the bell ring to cause salivation. In exchange for a reward, a person could be trained to push a lever every time they hear the bell. (operant conditioning). Operant conditioning is when the bell rings to signal that the subject must press the lever to receive the reward. Lever pressing is an operant, spontaneous response. Overall the bell serves as both a conditioned stimuli, inducing a Pavlovian response to salivation and a discriminative stimulus. It also indicates the potential for lever pushing, which can be an operant response (Skinner 2018, 2018).
