Four-month-old Jeremy has learned that his feedings occur after he hears the refrigerator door open and close. In this example, learning has occurred through which type of process?

A) Classical conditioning
B) Observational learning
C) Social learning
D) Infants cannot learn prior to 6 months of age.

Jeremy has learned to associate the sound of the refrigerator door with the event of being fed. This is an example of classical conditioning, where a neutral stimulus (the sound of the refrigerator door) becomes associated with an unconditioned stimulus (food) that automatically produces an unconditioned response (feeling of hunger or anticipation of eating). Over time, the neutral stimulus alone can elicit a conditioned response similar to the unconditioned response.
