The study of behavior without reference to mental processes was of special interest to B. John B. Watson
Explanation:
John B. Watson is known for his Classical Conditioning studies and he focused on behavior without giving much importance to the mental processes. He preferred to focus on what was visible, thus the behavior.
Unlike him, <em>Piaget, Freud </em>and <em>James </em>focused mostly on the mental processes. Examples are Psychoanalysis and the study of cognition development.
