b. Classical conditioning

c. Spontaneous recovery

d. Operant conditioning

In psychology, the term operant conditioning refers to a method of learning that is done by using rewards and punishments to either make the desired behavior happen more often (rewards) or to make it happen less often (punishments). The person given the rewards of punishments then learns the "correct" behavior and then the behavior starts happening without the presence of the rewards or punishments.

In this example, the desired behavior would be that Julio keeps the bed dry all night, therefore she starts giving him gold stars (rewards) for keeping it dry. After a week of doing so, Julio has changed his behavior and keeps the bed dry. Therefore, this change in behavior best illustrates the value of operant conditioning.
