Learning Theory (2Q1)
 Learning
 relatively
permanent
change in an
organism’s
behavior due
to experience
Classical Conditioning (2Q1)
Ivan Pavlov
1849-1936
Russian physician/
neurophysiologist
Nobel Prize in 1904
studied digestive
secretions
Classical Conditioning
“Pavlovia Conditioning” (2Q1)
 Classical Conditioning: when an old response
(unlearned… like salivating to food, ) becomes attached to
a new stimulus (like a noise/light etc.)
 organism learns to associate the two stimuli together
 “Neutral stimulus” does not initially elicit a response, it
must be conditioned (learned)
Pavlov repeatedly rang a tuning fork (once a neutral
stimulus) as meat powder placed on dog’s tongue
Dog salivated even if no food was given with sound
Salivation to sound becomes conditioned (learned)
Classical Conditioning (2Q1)
Classical Conditioning (2Q1)
Unconditioned Stimulus (UCS):
event that leads to a predictable
response without training
Unconditioned Response (UCR):
reaction that occurs automatically to
Unconditioned Stimulus
Conditioned Stimulus (CS): neutral
event that with training leads to a
learned response
Conditioned Response (CR): this is
a learned response to a stimulus
UCS

Classical Conditioning (2Q1)
Generalization: responding to a stimulus similar to the
original one without training

Extinction: is when a conditioned response dies out if not
regularly linked to the unconditioned stimulus
