2. Classical Conditioning
Ivan Pavlov
Studied Digestion of Dogs.
Dogs would salivate before they were given food (triggered by sounds, lights etc…)
Dogs must have LEARNED to salivate.

3. Classical Conditioning
This is passive learning (automatic…learner does NOT have to think).
First thing you need is a unconditional relationship.
Unconditional Stimulus (UCS)- something that elicits a natural, reflexive response.
Unconditional Response (UCR)- response to the UCS.

4. Classical Conditioning
Next you find a neutral stimulus (something that by itself elicits no response).
You present the stimulus with the UCS a whole bunch of times.

5. Classical Conditioning
After a while, the body begins to link together the neutral stimulus with the UCS.
Acquisition

6. Classical Conditioning
We know learning takes places when the previously neutral stimulus elicits a response.
At this point the neutral stimulus is called the conditioned stimulus (CS) and the unconditional response becomes the conditioned response (CR).

7. Classical Conditioning
TRICKY FACT: We know learning exists because the CS is linked to the UCS.
This is called ACQUISITION.
Acquisition does not last forever.
The moment the CS is no longer associated with the UCS, we have EXTINCTION.

8. Popular Classical Conditioning Examples
See if you can identify the UCS, UCR, CS and CR.
Classical Conditioning as portrayed in The Office.
A modified version of Clockwork Orange scene. Warning…it is still graphic!!!

9. Timing Matters
Delayed Conditioning: present CS, while CS is still there, present UCS.
Trace Conditioning: present CS, short break, then present UCS.
Simultaneous Conditioning: CS and UCS are presented at the same time.
Backward Conditioning: UCS is presented, then CS is presented.

10. Spontaneous Recovery
Sometimes, after extinction, the CR still randomly appears after the CS is presented.

11. Generalization and Discrimination
Something is so similar to the CS that you get a CR.
Something so different to the CS so you do not get a CR.

12. Classical Conditioning and Humans
John Watson brought Classical Conditioning to psychology with his Baby Albert experiment.
Click to see Baby Albert to some nice jazz.
This type of Classical Conditioning is also known as Aversive Conditioning.

13. First-Order and Second-Order Conditioning
First Order Conditioning.
Bell + meat = salivation.
Bell = Salivation.
Second Order Conditioning
(After first order conditioning has occurred)
Light + Bell = Salivation.
Light = Salivation.

14. Learned Taste Aversions
When it comes to food being paired with sickness, the conditioning is incredible strong.
Even when food and sickness are hours apart.
Food must be salient (noticeable.)

15. Garcia and Koelling Study
Studied rats and how they make associations.
Some associations seem to be adaptive. CS
UCS
Learned Response

Shock
Fear
Radiation (nausea)
