What is the difference between the traditional Pavlovian approach and the contemporary view on what is actually learned in classical conditioning?

What will be an ideal response?

Answer: A good answer will include the following key points.
• According to Pavlov, what is learned is an association between two stimuli, the unconditioned stimulus and the conditioned stimulus.
• Contemporary psychologists think that what is actually learned is information conveyed by one stimulus about another. For example, if A occurs then B is likely to follow.
• Robert Rescorla demonstrated that the pairing of an unconditioned stimulus and a neutral stimulus is not enough to produce learning.
• To become a conditioned stimulus, the neutral stimulus must reliably signal, or predict, the unconditioned stimulus.
