What was Watsons fundamental disagreement with Freuds approach?

Watson disagreed with Freud's emphasis on unconscious processes and the importance of early childhood experiences in shaping personality. Watson believed that behaviorism should focus on observable behaviors that could be scientifically studied and manipulated, rather than on subjective experiences like those proposed by Freud. Watson's approach was more focused on environmental factors influencing behavior, while Freud's psychoanalytic theory emphasized inner conflicts and unconscious desires.
