II. Habituation and Sensitization
A. Habituation =
Examples of habituation in everyday world:
B. Sensitization =
Examples of sensitization in everyday world:
III. Classical Conditioning/Pavlovian Conditioning
A. Definition –
B. History
Pavlov’s Dogs:
Why did the dogs salivate in response to the bell?
C. The Classical Conditioning Equation:
Unconditioned Stimulus (UCS)  Unconditioned Response (UCR)
Neutral Stimulus (NS) + Unconditioned Stimulus (UCS) Unconditioned Response (UCR)
(Repeated Pairings of NS and UCS establish an association between the two)
Conditioned Stimulus (CS)  Conditioned Response (CR)
