1. Classical Conditioning

2. Learning
A relatively permanent change in behavior due to experience

3. Classical Conditioning
Have you ever been “conditioned”?
What does that mean?

4. Classical Conditioning
A type of learning where a stimulus gains the power to cause a response because…
it predicts another stimulus that already produces the response
Basically…associating

5. In your own words…

6. 1. Unconditioned Stimulus (UCS)
A stimulus that triggers a response automatically and reflexively.

7. In your own words…

8. 2. Unconditioned Response (UCR)
The automatic response to the unconditioned stimulus

9. In your own words…

10. 3. Conditioned Stimulus (CS)
A previously neutral stimulus that, through learning, has gained the power to cause a conditioned response.

11. In your own words…

12. 4. Conditioned Response (CR)
The response to the conditioned stimulus.

13. In your own words…

14. Let’s draw this out

15. Experiment
UCS
UCR CS CR
Pavlov’s Dogs
Lemonade
Jaws
The Office
Squirt Gun

16. An example from the Office

17. An example from our own class

18. Can you train Pavlov’s dog?
I need a volunteer…

19. Warmup
UCS/UCR/CS/CR

20. Quick Recap
Jacob's date was wearing a very alluring perfume on their recent date. The date itself was quite exciting. The following day when Jacob gets into his car he smells the lingering scent of his date's perfume and his heart rate jumps up immediately.
UCS?
UCR?
CS?
CR?

21. Acquisition What do you think it means?
Associating a neutral stimulus with a UCS so that it comes to elicit the CR
AKA?
Little time between presentation of UCS and CS

22. Extinction What do you think it means?
The diminishing of a conditioned response
AKA?
Once the dog has been conditioned, its conditioned salivation response will not last forever.

23. Spontaneous Recovery
The reappearance, after a pause, of an extinguished conditioned response
AKA?

24. Behaviorism Influential during the 1st half of 20th century
Psychology should be an objective based on observable behavior
John Watson (1913) urged colleagues to discard reference to inner thoughts feeling and motives
No more introspection

26. Give me a dozen healthy infants, well-formed, and my own specified 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, even beggar-man and thief, regardless of his talents, penchants, tendencies, abilities, vocations, and race of his ancestors. --John Watson, Behaviorism, 1930

27. Little Baby Albert…
Let’s watch a video on how Watson conditioned Little baby

28. Generalization
The tendency for stimuli similar to the CS to elicit similar responses.
The dogs salivated upon hearing the sound of bells that were similar to, but not the same as, the one to which Pavlov conditioned them to respond.

29. Discrimination
The ability to distinguish between a conditioned stimulus and stimuli that do not signal an unconditioned stimulus
Pavlov was also able to train his dogs to discriminate one sound from another and to respond to only one type of bell

30. Taste Aversion
John Garcia researched how classical conditioning could be related to food
How so?
