  7. Who influenced Watson? • Reacts against Wundt and James -and their followers such as John Dewey • Infuenced by Loeb (tropisms) and Henry Donaldson (white rat neurology) -studied the myelinization of white rat nervous system & consequent changes in the complexity of their behavior. • Pavlov

  8. Watson’s main contributions • Official founder of behaviorism as an independent and valid approach to psychology • Is a radical behaviorist • Introduces the notion of conditioned emotional response (little Albert) • Three emotions: fear, rage, love -all emotional life built on those • Applies this to advertising
