6 Unconditioned Stimulus
UCS Stimulus to which an organism has a natural response Smell favorite food, a ballis thrown, you hear a noise

7 Unconditioned Response
UCR Organism’s natural response to a stimulus

8 Neutral Stimulus Neutral Alone, does not evoke any response

9 Conditioned Stimulus CS A neutral stimulus that has been associated with a natural response

10 Conditioned Response CR Learned response to a conditioned stimulus that is not natural

11 In Pavlov’s experiment with the dog, bell, food and salivation, what is the UCS, UCR, Neutral, CS and CR?

12 Bringing in the Dog Food = UCS Salivating = UCR
Bell = Neutral Stimulus Bell is paired with Food After time, the bell ALONE creates salivating Bell = CS; Salivation = CR

13 How and when have you been classically conditioned?
What factor’s should impact whether conditioning is effective?

14 Pavlov’s Observations
Time between CS and UCS CS should precede CR by .5 seconds for strongest response.

15 Repetition: More often CS and UCS are paired, the stronger the response.

16 Generalization: similar CS should cause same CR (Allergies)
Discrimination: discriminate between CS

17 Extinction: if after conditioning the CS is presented repeatedly without the USC, the CR eventually fades.

18 Applications of Classical Conditioning
Counterconditioning: pleasure and fear simultaneously Flooding: increase contact w/ stimulus

19 Applications of Classical Conditioning
Desensitization: sequence of events to gradually reduce response.
