1. Classical Conditioning Pavlov’s Experiment

2. Neutral Stimulus Pavlov used a tuning fork Pavlov used a tuning fork A tuning fork has nothing to do with salivation A tuning fork has nothing to do with salivation

3. Unconditioned Stimulus Food normally will lead to salivation. Food normally will lead to salivation. You do not need to be taught to salivate when you see food. 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 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 tuning fork Pavlov wanted the dog to have a physical reaction to the tuning fork The tuning fork became the conditioned stimulus The tuning fork became the conditioned stimulus

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

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

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

9. Extinction Behavior stops if the dog is no longer presented with food. 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 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. 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 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 (Crying/scared)

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