Classical Conditioning
Ivan Pavlov (1849 - 1946)

Learned Response - learned by paring a neutral
stimuli with a natural stimuli (Unconditioned
Stimuli)

Discovered by Ivan Pavlov while studying
digestion
Classical Condition - Pavlov’s Experiment
Before Conditioning

Neutral Stimulus:


Neutral Stimulus:





Dog Salivates
Dog Shown Meat (UCS
Unconditioned Stimulus)
Dog Salaivates (UCR
Unconditioned Response)
After Conditioning

Conditioned Stimulus:


Shown Meat
Unconditioned Response
Unconditioned Stimulus

Bell Rings
Unconditioned Stimulus


Bell Rings (neutral stimulus)
Gets Dog’s Attention
(unrelated to meat)
During Conditioning

Before Conditioning
(Unconditional Stimulus removed)


Bell Rings
(no meat shown)
Conditioned Response

Dog Salivates
Extinction

Extinction of Conditioned Response



Un-learning a conditioned response
The strength of a conditioned response
diminishes if not reinforced.
Spontaneous Recovery


Immediate reemergence of CR
Single paring of CS with CR
Stimulus Generalization

Responding similar stimuli as though it were
the Conditioned Stimuli
Stimulus Discrimination

Ability to differentiate between stimuli
