  2. The schools of behaviorism

  3. The schools of behaviorism

  4. History of Behaviorism Thorndike (1900’s - 1932) an American psychologist whose theory of • connectionism (forming associations between stimuli and responses)was dominant in the US during the first half of the 20th century. • Thorndike focused much of his attention on education, especially learning and transfer. He thought transfer happened only when the situations have identical elements and call for similar responses.

  5. History of Behaviorism Thorndike The instinctive and intelligent behavior of chickens Studies under James at Harvard Goes to Columbia Puzzle boxes for cats Not reasoning nor insight Trial and error Single response, no problem Two response, but problem

  6. History of Behaviorism Thorndike Law of Effect Annoyers Satisfier Stamp-in=reinforce The effect of any action thus determines whether it becomes the response to a given stimulus or not.

  7. History of Behaviorism Thorndike Law of Exercise A response will be more strongly connect to a stimulus in proportion to the number of times it has been connected with that situation and to the average vigor and duration of the connection

  8. History of Behaviorism Thorndike Animals are not people! To T: The number, delicacy and complexity of cell structures in human brain make for a corresponding number, delicacy and complexity of associations.

  10. Classical Conditioning:The Elements of Associative Learning Ivan Pavlov Typical Conditioning Trial: ריור Test Trial: ריור

  11. Classical Conditioning:Definitions Unconditioned(al) Stimulus (US): a stimulus that has the ability to produce a specified response before conditioning begins. Unconditioned(al) Response (UR): the response produced by the US. (SALIVATION PRODUCED BY THE FOOD)

  12. Classical Conditioning:Definitions Conditioned(al) Stimulus (CS): an initially neutral stimulus that comes to produce a new response because it is associated with the US. Conditioned Response (CR): the response produced by the CS. (SALIVATION PRODUCED BY THE BELL)

  15. The schools of behaviorism

  16. Philosophical Foundations of Learning Theory Empiricism says that all knowledge comes from experience. Beginning with Aristotle, empiricist philosophers have proposed theories to explain how experience gets translated into knowledge. The basic process proposed was association. An association is a connection between ideas. If two ideas (representations) are associated, when you think of one you will automatically think of the other. For example: ? ? ?

  17. Philosophical Foundations of Learning Theory Why chair? Probably because we see tables and chairs together so often. This statement points to two key principles philosophers used to explain the formation of associations: Temporal Contiguity Two events that are experienced at the same time will tend to be associated. Frequency The more often we experience events that are contiguous, the more strongly we will associate them.

  18. Watson • John B. Watson (1916, 1926), an American psychologist is credited as the founder of behaviorism. • Watson strove to make the new field of psychology more scientific. • He believed that all behavior, even that which appeared instinctive, is the result of conditioning that occurs in response to a stimulus. • Like E.L. Thorndike, Watson was popular in the first half of the 20th century

  19. “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 be any type of specialist I might select – a doctor, a lawyer, artist…” -Watson 1924

  20. Who was he • Fear of the dark • Father was a drunk and abandonded the family • The original fight club • Talked his way into Furman college • University of chicago to study Philosophy • First to build a rat maz

  21. Running record ex. • 12 min., 12 min., 3 min., 8 min., 2 min., 3 min., then .33 min, .33 min, .16 min., .08 min, .108 min. A fundamental discovery: Learning is not an even process: Rather, slow haphazard improvements followed by a sudden solution.

  22. From rats to people • 1) studied how young he could get rats to solve the mazes, • 2) turned to neurology. Killed rats aged from 1 to 30 days and examined the state of their brains at each age. Wanted to link their psychological abilities with the physiological development of their cortex.

  23. Ph. D • "If you could understand rats without the convolutions of introspection, could you not understand people the same way?"

  24. Youngest professor • (a) Previous study had been of vision. Hooded birds. • (b) In 1906 Watson began to operate on a group of six-month-old-old rats who had previousl¥ learned the maze. • Made one group blind by removing eyeballs. • One group deaf by removing middle ear. • Took out olfactor bulb of one group to be sure they • could not smell. • Snipped the whiskers off two rats. No effect.

  25. Therefore • WATSON HYPOTHESIZED THAT RATS WERE LEARNING BY • KINESTHETIC SENSE. HE & HARVEY CARR --IDENTICAL MAZE, HALF AS LARGE, rats that had learned the maze kept running into walls. • "I never want to see another rat go round the maze.”

  26. Pavlov’s influence • Won Nobel in 1905 • Translated in 1915 • to condition humans with a bell (CS) a small electric shock to the foot, (US) and a toe-flexing response. The bell and shock occurred simultaneously. The reflex was not fully reliable but some were conditioned. A subject trained in may and retested in October required only one reminding shock for the reflex to reappear. They carried out a number of experiments, and Watson believed that emotions as well as saliva flows and toe movements could be conditioned

  27. Baby love • First to observe children in their natural setting • Believe mental illness was conditioned response • Wanted to become a social engineer • "are really consolidations of instinct and habit."

  28. Getting radical • -- Society can employ psychology to retrain those of its members who did not conform to civilised standards. The criminal, the laz¥, the drifters, and even the mentally ill could be turned into useful members of society. It would not be left up to them to choose that. And those few criminals whose nervous systems were so askew that they could not be conditioned into decent members of society ought to be "etherized."

  29. Ten gallons of rye and college students? • The first study of the affects of alcohol on performance

  30. Puzzle box

  31. So what did he do? • Psychology as the behaviorists views it • President of the APA • Editor of the psych bulliten • And the most famous experiment of them all

  32. Contiguity • - (Behaviorism)- One explanation for learning in behaviorism; an association is built between two events simply because they occured simultaneously or overlapping in time.For example, if food is presented while some auditory signal is given, a dog will "learn" to salivate when it hears the auditory signal, even if no food is present.

  33. Little Albert • three basic emotional reactions: fear, rage, and love. • Prove he could condition responses

  34. The Psychological Care of the Infant and Child • Children should be awakened at 6:30 A.M. for orange juice and a pee. Play 'till 7:30. Breakfast should be at 7:30 sharp; at 8:00 they should be placed on the toilet for twenty minutes or less 'til bowel movement is complete. Then follow up with a verbal report. The child would then play indoors 'till 10P00 A.M., after 10:00 outside, a short nap after lunch, then "social play" with others. In the evening a bath, quiet play until bedtime at 8:00 sharp.=1928

  35. He argued that institutions like the Boy Scouts and the YMCA could lead to homosexuality. Girls were even in more danger because they held hands, kissed, and slept in the same bed at pajama parties. "Our whole social fabric is woven so as to make all women slightly homosexual.” • Mothering is a sexual act • Kids should be removed 4 weeks after

  36. Methodological Behaviorism – • All psychologists can observe is behavior so that is all they should study. • Law of Parsimony – simpler explanations are preferred • “mental” events cannot be measured and so should not be studied • Deterministic Stimulus-Response (S-R) • 6 • Watson’s Methodological • Behaviorism • Extreme nurturist position • Believed everything of importance was • learnt – not innate

  37. Scandal • "I did not know anything about industry, and above all • that I did not know the habits and dwelling places of that peculiar and widely distributed animal we call the "consumer." Theoretically, I had been studying this animal all my days; practically, I did not know how to get at him."

  38. Love letter • I have been an awful sinner, I know.... Promise me your heart and body will still be mine.... Every cell I have is yours, individually and collectively. I can't be any more yours than if a surgical operation made us one.... [I wish we could go] to the North Pole where the days and nights are six months long, [He implied that this would allow record-breaking kissing.] Everything will be lovely and we ought to play safe. Still, play we will.... My total reactiions are positive toward you. So, likewise, each and every heart reaction."

  39. Coffee Break • “good to the last drop”

  40. Lucky stripe • “Lucky Strike Means Fine Tobacco.” • "Since the time of the serpent in the garden of Eden influenced Eve and Eve in turn persuaded Adam, the world has tried to find out ways and means of controlling human behavior. In advertising, we call the process selling."

  41. "dispense with rational copy almost entirely."

  42. From door to door to this • "…tell him something that will tie him up with fear, something that will stir up a mild rage, that will call out an affectionate or love response, or strike at a deep psychological or habit need."

  43. Girls! Don't worry anymore • about smoke-stained teeth • or tobaco tainted breath. • You can smoke and still be lovely • if you'll just use Pebeco twice a day.
