Introduction to MutationsCurrent LectureBehavioral/Social Learning TheorySetting the Stage- American zeitgeist-equal opportunity- Distinguishing ideao Traditional behaviorism: observable behaviorJohn B. Watson- Mental states, consciousness, the mind, thoughts, feelings...worthless- Overt behavior: can be observed, predicted, controlled- Influenced by conditioning, Pavlov, Thorndike- Who you are as a person is basically the result of you being conditioned to respond in certain ways to certain situationsB.F.
