CONDITIONING?

HOW DO WE LEARN?
Most learning is associative
learning
By linking two events that occur close together.
How many of you have to have
popcorn when you go to the
movies???
Walk on the right side of the hall?
Sleep a certain way? Have a bedtime
ritual?
Fun Fact:
For behavior to become a habit it
usually takes 66 Days

WHAT IS CLASSICAL CONDITIONING?
Learning through association; a tendency to connect
events that occur together in time and space

CLASSICAL CONDITIONING
Ivan Pavlov developed the
framework for CC:
Learning to associate one stimulus
with another, i.e. “Stimulus-toStimulus Learning”

HOW IS THE FEAR OF LIGHTNING A SIMPLE CLASSICAL CONDITIONING SITUATION?
At any one time, all around the world, there are 2,000 thunderstorms happening,
producing over a 100 lightning strikes a second. That's over 8 million lightning bolts
every day unleashing the power of 2 million tons of TNT.
We associate 2 stimuli:
We see lightning... & then hear
thunder. (speed of light is faster than the
speed of sound)
Lightning ... THUNDER
Lightning ... THUNDER
Lightning ... THUNDER
Eventually, you see lightning &
then flinch... anticipating the second
stimulus.
You have paired lightning & thunder.
You have learned that when there is
lightning, thunder may follow.

Unconditioned Stimulus (UCS): a
stimulus that naturally and automatically
triggers a response.
Unconditional Response
(UCR): the unlearned,
naturally occurring
response to the UCS.

Neutral Stimulus (NS): an unrelated
stimulus that will become the Conditioned
Stimulus
Aim: How do we learn through classical conditioning?
Conditioned Stimulus (CS): an
originally irrelevant stimulus that, after
association with the UCS, comes to
trigger a response.
Conditioned
Response (CR): the
learned response to a
previously neutral
stimulus.

After repeated
episodes.... creating
‘Conditioning’:
UCS: Thunder
UCR: Fear
NS: Lightning
CS: Lightning
Pairing UCS & CS =
CR: Fear
