Pavlov’s Experiment in “Classical Conditioning”
Identify the following components of Pavlov’s experiment.





1.__ Neutral Stimulus
2.__ Unconditioned (Unlearned) Stimulus
3.__ Unconditioned (Unlearned) Response
4.__ Conditioned (Learned) Stimulus
5.__ Conditioned (Learned) Response
A. Bell B. Food
C. Salivation (to Food) D. Salivation (to Bell)

Acquisition

Acquisition:

Classical Conditioning:

Initial stage, when one links a neutral stimulus and an unconditioned stimulus

Neutral stimulus begins triggering conditioned response

Operant Conditioning:

The strengthening of a reinforced response

Neutral stimulus should come (.5 seconds) before the unconditioned stimulus

Acquisition
The Conditioned Stimulus (CS) needs to come half a second before the Unconditioned Stimulus (UCS) for acquisition to occur.

Acquisition

Higher-Order Conditioning:

The conditioned stimulus in one experience is paired with a new neutral stimulus, creating a second (often weaker) conditioned stimulus

E.g. An animal that learns that a tone predicts food might then learn that a light predicts the tone and may begin responding to the light alone

Generalization

Generalization:

The tendency, once a response has been conditioned, for stimuli similar to the conditioned stimulus to elicit similar responses

John B. Watson, Rosalie Rayner: “Little Albert”

Generalization

Interpret this quote:
“The cat, having sat upon a hot stove lid, will not sit upon a hot stove lid again. But he won't sit upon a cold stove lid, either.”
–Mark Twain

Discrimination

Discrimination:

The learned ability to distinguish between a conditioned stimulus and stimuli that do not signal an unconditioned stimulus

Discrimination


Extinction

Extinction:

The diminishing of a conditioned response

Classical Conditioning:

An unconditioned stimulus
(US) does not follow a conditioned stimulus (CS)

Operant Conditioning:

A response is no longer reinforced

Extinction


Spontaneous Recovery

Spontaneous Recovery:

The reappearance, after a pause, of an extinguished response

Learned Helplessness

Learned Helplessness:

The hopelessness and passive resignation an animal or human learns when unable to avoid repeated or aversive events

Learned Helplessness

How might being bullied as a child lead to the individual experiencing “learned helplessness?”

How might school leveling/tracking lead to the individual experiencing “learned helplessness?”

How would you suggest the individual should work to correct this learned behavior ?

Biological Predispositions
John Garcia showed that the duration between the CS and the US may be long
(hours), but yet result in conditioning. A biologically adaptive CS (taste) led to conditioning but other stimuli (sight or sound) did not.

Biological Predispositions
Even humans can develop classically to conditioned nausea.

Biological Predispositions

Psychologists may suggest that alcoholics use “Antabuse,” a pill that causes nausea when combined with alcohol

The use of this drug may serve to condition the alcoholic to become nauseous when drinking alcohol (aversive conditioning)

Applications of
Classical Conditioning
1. Former crack cocaine users should avoid cues (people, places) associated with previous drug use.
2. Through classical conditioning, a drug (plus its taste) that affects the immune response may cause the taste of the drug to invoke the immune response.

Applications of
Classical Conditioning
John B. Watson used classical conditioning procedures to develop advertising campaigns for a number of organizations, including Maxwell House, making the “coffee break” an American custom.
