## Step 1<br />Operant conditioning is a learning process where behavior is controlled by consequences. It is a method of learning that occurs through rewards and punishments for behavior. This concept was developed by B.F. Skinner, an American psychologist.<br /><br />## Step 2<br />Ivan Pavlov is known for classical conditioning, not operant conditioning. Classical conditioning is a learning process that occurs through association. In this process, a neutral stimulus is paired with a significant stimulus, eventually leading to the neutral stimulus alone triggering a response.<br /><br />## Step 3<br />John B. Watson is known as the father of behaviorism, but he is not specifically associated with the study of operant conditioning.<br /><br />## Step 4<br />Albert Bandura is known for his work in social learning theory, which emphasizes the role of observational learning, imitation, and modeling.
