Next is Carl Jung, and his beliefs were similar to Freud's. He said that our ideas are influenced by the beliefs that we inherit. After Jung was John Watson. He believed that only overt behavior could be studied and he developed behaviorism which was the study of how people act and he learned how to control their actions.
Ivan Pavlov was a behaviorist who developed a dog experiment that showed how to train a response to a previous neutral stimulus. Another Psychologist was BF Skinner, and he focused on rewards and punishments and their effect on our behavior.
Next is Abraham Maslow, and he was one of the most important Humanists. He thought that people had to have certain things to grow and become successful. He also developed the hierarchy of needs.
Carl Rogers is the next psychologist in our line-up, and he was another early humanist. He developed client-centered therapy, which encouraged people to identify the resources within themselves to help them change what they don't like about themselves.
Finally, we have Jean Piaget. He was a cognitive psychologist and stated that children are not blank slates that can learn anything, and that they go through developmental stages of processing information and learning. He also helped shape the primary school in America.
