1. Watson - Classical Behaviorism

1. Watson claimed that psychology, as a science, can only study observable behavior. That is, psychology should take behavior as its research object. Therefore, Watson's research route can be expressed by the "stimulus-response" formula (S-R). He insisted that psychology can only take behavior as its object and is a science that studies behavior.

2. The formation of Watson's behavioral psychological thought was largely influenced by the conditioned reflex theory of the Russian physiologist Pavlov.

3. In short, Watson denies psychology and consciousness, emphasizes behavior, and believes that all human behaviors are formed under the influence of the acquired environment.

Watson has a rather extreme famous saying. He said: "You give me a dozen children, in a good environment where I make the decision, regardless of their talents, abilities, or parents' occupations." Regardless of their race, I can train them to be doctors, lawyers, artists, big businessmen, or even beggars or thieves at will."

2. Skinner - New Behaviorism

1. Skinner adhered to the basic principles of behaviorism. He clearly pointed out that any organism tends to repeat behaviors that lead to positive consequences rather than repeat behaviors that lead to negative consequences.

2. The difference between Skinner's and Watson's thoughts is that he does not deny the existence of people's internal psychological activities, but he firmly believes that all human behaviors are determined by the external environment.
