1. Classical Conditioning
Pavlov’s Experiment

2. Neutral Stimulus Pavlov used bell
A bell has nothing to do with salivation

3. Unconditioned Stimulus
Food normally will lead to salivation.
You do not need to be taught to salivate when you see food.

4. Unconditioned Response
At the sight or smell of food a dog will salivate

5. Conditioned Stimulus
Pavlov wanted the dog to have a physical reaction to the bell
The bell became the conditioned stimulus

6. Conditioned Response
The dog began to salivate at the sound of the bell
Previously it had done nothing at this sound

7. Generalization: Oval
First Pavlov conditioned a dog to salivate at the sight of a circle.
Then it also began to salivate at the sight of an oval

8. Discrimination: Circle vs. Oval
To solve the problem of generalization
Only give food when there is a circle picture
Dog will learn to salivate only upon seeing a circle.

9. Extinction
Behavior stops if the dog is no longer presented with food.

10. Unconditioned Stimulus (Dinner was chili with brats and I had come down with the flu)
Unconditioned Response (reflex)
(That night I threw up dinner)
Conditioned Stimulus (The smell of Chili or brats)
Conditioned Response (makes me feel sick)

11. Little Albert
John B. Watson

12. Step 1: Present the rat
Albert laughs and tries to reach out and touch the white furry rat

13. Step 2: Loud noise
When Albert reaches out to touch the rat a metal bar is hit with a hammer.
Albert does not like this sound and begins to whimper

14. Generalization

15. Unconditioned Stimulus
(Loud noise)
Unconditioned Response
(Crying/scared)
Conditioned Stimulus
(Furry white rat)
Conditioned Response

16. Ethical Practice?
Now Albert will only play with blocks because his response to the furry white objects is fear.
Albert was later adopted and his behavior was not extinguished.
