Classical Conditioning
Learning
Lesson 1
Objectives
Define learning and provide examples.
Identify John B Watson, BF Skinner, and
Ivan Pavlov.
Describe and apply the components of
classical conditioning.
Warm Up
Identify some of the
things you’ve learned
in the past few
months.
Learning
Learning IS…
A process leading to
relatively permanent
change in behavior.
Learning is NOT…
Reflex:
Simple, unlearned behavior
controlled by the ANS
Instinct:
Inborn, complex pattern of
behavior of a species
Behaviorists
John B. Watson
Behaviorism
Study of observable
behaviors
BF Skinner
Behavior influenced by
history of
consequences
Behavioral Psychology
Study of how our behavior results from
stimuli in the environment and within
ourselves. (Stimulus-Response Learning)
Classical Conditioning
Operant Conditioning
Cognitive or Social Learning
Think-Pair-Share
“When I’m driving
and see a stoplight
turn red, I stop”
Stimulus – red light
Reaction – stop
Write down three
more conditioned
responses you do on
a daily basis.
Phone rings, pick it up
Bell rings, you switch
classes
Teacher asks ?, you
raise hand
Classical Conditioning
Stimulus in
environment triggers
response in subject.
Ivan Pavlov
(1849-1936)
Physiologist
researching digestion
in dogs
Activity
PsychSim 4.0 “Classical Conditioning”
This activity provides a review of Pavlov’s famous
experiment on the salivary response in dogs, as well as
the basic processes of classical conditioning: acquisition,
generalization, discrimination training, and extinction.

Pavlov’s Experiment
Before Conditioning (Pre-Learning)
During Conditioning (Learning)
Ring tuning fork (NS) No response from dog
Food (UCS) Dog salivates automatically (UCR)
Ring fork (NS) Present food (UCS) Salivation (UCR)
After Conditioning (Post-Learning)
Ring fork (CS) Salivation (CR)
Think-Pair-Share
What other
conditioned stimuli
may have existed in
Pavlov’s experiment?
General Principles of C2
Acquisition
Generalization
Distinguishing between different stimuli
Extinction
Stimuli similar to CS cause CR
Discrimination
Time period it takes for NS to be associated with UCS
Disappearance of CR to CS
Spontaneous Recovery
Previously extinguished CR returns suddenly
Eye Blink Experiment
UCS – puff of air in eye
UCR – blink
NS – tone
CS – tone
CR – blink
Emotional Conditioning
John B. Watson
Prove human
emotional reaction was
result of conditioning
Fear, rage, sadness

Albert Activity
Set up experimental design.
Give examples of generalization in
experiment.
Cite criticisms of experiment
Identify ways researchers could help
Albert get over his fears.
Albert Answers
Before:
Rat No Response
Loud noise Fear
During:
Rat Noise Fear
Generalization:
Criticisms:
After:
Rat Fear
Rabbit
Fur Coat
Screwed up kid
Didn’t fix him
Albert Answers
Fixing Albert’s Fears
Counter Conditioning: pleasant stimulus
presented with fear object, re-condition
Systematic Desensitization: gradually exposed
to fear-evoking stimuli in pleasant
circumstance
Flooding: exposed to fear stimulus until
response extinguished
Other Examples
Associate song with relationship…break
up, song makes you sad
Associate smells
Taste Aversion – Got sick eating spaghetti,
can’t eat it anymore
