Explanation:

Classical Conditioning: This is also known as Pavlovian conditioning because it was discovered by a behavioral psychologist named Ivan Pavlov. He described classical conditioning in his study conducted on dogs. He explained that when two different stimuli are linked together, they produce a new learned response in an animal or person.
