Classical Conditioning
Learning

Learning
 relatively
permanent
change in an
organism’s
behavior due
to _________
Behaviorism
 John B. Watson
 viewed psychology as
___________________
 generally agreed-upon
consensus today
 recommended study of
behavior without reference
to ___________________
 not universally accepted by all
schools of thought today
Association
 We learn by ___________
 Our minds naturally connect events that
occur in sequence
 Aristotle 2000 years ago
 John Locke and David Hume 200 years ago
 Associative Learning
 ______________________________
 two stimuli
 a response and its ______________
Association
Event 1
Event 2
 Learning to
associate two
events
Sea snail associates splash with a tail shock
Seal learns to expect a snack for its showy antics
Classical or Pavlovian
Conditioning
 We learn
to
associate
two
________
Operant Conditioning
 We learn to
associate a
__________
and its
___________
Classical
Conditioning
 ____________
 1849-1936
 Russian
physician/
neurophysiologist
 Nobel Prize in
1904
 studied digestive
secretions
Classical
Conditioning
 Classical Conditioning
 organism comes to associate two stimuli
 a _______ stimulus that signals an
__________ stimulus begins to
produce a response that anticipates and
prepares for the unconditioned stimulus
Pavlov’s Classic
Experiment
Example 1
Before Conditioning
UCS (food
in mouth)
UCR
(salivation)
During Conditioning
Neutral
stimulus
(tone)
No
salivation
After Conditioning
UCS (food
in mouth)
Neutral
stimulus
(tone)
UCR
(salivation)
CS
(tone)
CR (salivation)
Classical
Conditioning
 Unconditioned Stimulus (UCS)
 stimulus that unconditionally--_________ and
__________--triggers a response
 Unconditioned Response (UCR)
 __________, _________ occurring response
to the unconditioned stimulus
 salivation when food is in the mouth
Classical
Conditioning
 Conditioned Stimulus (CS)
 originally irrelevant stimulus that, after
association with an unconditioned stimulus,
comes to ________________________
 Conditioned Response (CR)
 ___________________ to a previously
neutral conditioned stimulus
Classical
Conditioning
Example 2
 ___________
 the initial stage in classical conditioning
 the phase associating a neutral stimulus with
an unconditioned stimulus so that the neutral
stimulus comes to elicit a conditioned
response
 in operant conditioning, the strengthening of
a reinforced response

Classical
Conditioning
 __________
 diminishing of a CR
 in classical conditioning, when a
UCS does not follow a CS
 in operant conditioning, when a
response is no longer reinforced
Classical
Conditioning
Strength
of CR
Acquisition
(CS+UCS)
Extinction
(CS alone)
Spontaneous
recovery of
CR
Extinction
(CS alone)
Pause
Classical
Conditioning
 Spontaneous Recovery
 ____________, after a rest
period, of an extinguished CR
 Generalization
 tendency for stimuli similar to CS
to elicit _______ responses
Classical
Conditioning
 _____________
 in classical conditioning, the learned
ability to distinguish between a CS
and other stimuli that do not signal a
UCS
Generalization
