The operant conditioning was coined by the behaviorist BF Skinner, which is why you may occasionally hear it called skinnerian conditioning. As a behaviorist, Skinner believed that it was not really necessary to look at internal thoughts and motivations to explain behavior. Instead, he suggested, we should look only at the observable external causes of human behavior.
Based on these principles, Skinner created the operant conditioning chamber (aka Akinner box) is a device used to study the principles of operant conditioning.
