1 Little Albert J.B. Watson & Rosalie Rayner’s Study on Conditioned Emotional Responses
2 Psychology c. 1920’sBefore the 1920’s, field dominated by Psychoanalytic School of Thought- Sigmund Freud.Behaviorism movement started in the 1920’s.Very different view vs. psychoanalytic school.Watson and other behaviorists claimed:instead of people’s behavior coming from within, their behavior comes from different environmental & situational stimuli.
4 Watson and his contemporaries came of age as the Industrial Revolution Watson and his contemporaries came of age as the Industrial Revolution. At the turn of the 20th century, with Sigmund Freud leading his own vanguard in psychoanalysis, psychology was trying to find its niche. Often paired with philosophy in university departments, psychology focused on the subjective study of "introspection," research based on patients' reported feelings.
5 After seven such pairings, Albert B After seven such pairings, Albert B. cried and avoided the animal--even when there was no loud noise.In fact, days later, he showed fear when he saw the rat, the rabbit, the dog, and a sealskin coat.He also had a "negative" response to a bearded Santa Claus mask and the hair on Watson's head.
6 Watson promoted new ideal. Coined the term ‘behaviorism’.Rejected the idea of consciousness.Labeled Freud's views: ‘voodooism’.According to Watson, scientists could best study human mind by noting what humans do.And he meant "to gain experimental control over the whole range of emotional reactions."
7 “Give me a dozen healthy infants, well-formed, and my own special world to bring them up in, and I’ll guarantee to take any one at random and train him to become any type of specialist I might select: doctor, lawyer, artist, merchant chief, and, yes, beggarman and thief, regardless of his talents, penchants, tendencies, abilities, vocations and race of his ancestors.”- J.B. Watson, 1924
