CLASSICAL CONDITIONING

Classical Conditioning (CC)

-Ivan Pavlov’s Experiment

Classical Conditioning & Advertisement



 Classical conditioning in marketing is a valid

way to promote products.



 Advertisers pair their product with other

positive stimuli, such as sex, pleasant music,

humour, attractive colours and celebrities.

Learning to Fear



 Research suggest that we acquire fobias

through association.



 Watson and Raynor conditioned ―Little

Albert‖ to be afraid of white rats by pairing

the neutral stimulus (rats) with an

unconditioned stimulus (loud noise).

Learning to Fear (Cont..)

Unlearning Fear



 (How) can we unlearn to fear?

 Counterconditioning  conditioning new responses to

emotion-arousing stimuli

 The process of pairing a conditioned stimulus with a

stimulus that elicits a response that is incompatible

with an unwanted conditioned response

 Another child’s fear of rabbits was removed by pairing

the stimulus which elicited fear with a stimulus that

elicited happiness.

Examples of Classical Conditioning

(Zimbardo, 1999)

1. "When I was in the first grade, we went outside every day

for recess. To get to the playground, I had to pass by the

"territory" of a bully who was in the fourth grade. This

bully took great pleasure in punching me in the stomach

which caused me great pain, sweating, and anxiety. One day

the bully was out of school. Although the bully wasn’t

there, when I walked by his "territory" I still got a full-

blown anxiety response! I was sweating and my heart was

racing. When I got home that night, I told my parents what

happened and my mother found her old psychology

textbook and explained to me that my experience was the

result of Classical Conditioning."

Can you see how this story fits the CC

model?

 The UCS is?

a. a full-blown anxiety response

b. the ―territory‖ of the bully

c. being punched in the stomach by the bully

d. going to the library

 The CS is?

a. a full-blown anxiety response

b. the ―territory‖ of the bully

c. being punched in the stomach by the bully

d. going to the library

 The UCR is?

a. a full-blown anxiety response

b. the ―territory‖ of the bully

c. being punched in the stomach by the bully

2. While caring for a friend’s dog, you notice that it displays a

fear-like posture as you roll up a newspaper. You try this

several times more and become convinced that this dog is

generally afraid of rolled up newspapers.



 UCS – hitting the dog with a rolled up newspaper

 UCR – dog’s fear-like posture

 CS – rolled up newspaper

 CR – dog’s fear-like posture

 Dog’s fear-like posture is a natural response to being hit and

an acquired response to the sight of various objects.

More Examples of CC (extinction)..



3. Joan, an animal trainer, has been phobic about monkeys since an

earlier attack. However, because of the money, she has agreed to

work with monkeys for a movie studio. At first, just going anywhere

near cages used to make Joan tense, sweaty, and apprehensive.

Lately, though, things have changed. Working with such cuddly,

affectionate, human-like creatures is causing Joan to wonder why she

ever felt such extreme distress.



 UCS – monkey attack

 UCR – fear of monkey attacks

 CS – monkeys

 CR – fear of monkeys

 Extinction is occurring as contact continues without further

incident; i.e., presenting the CS (monkeys) without the US (the

attack).

More Examples of CC (discrimination)..



4. At a red light, Bob and Fred automatically tensed and felt

chills when they heard the screech of tires behind them. Later,

while watching a car race, Bob remarked how the screeching

of tires was having little effect then. Fred agreed and wondered

why they reacted at all, because neither had as much as a dent

on his driving record.



 Screeching tires (CS) often cause people to tense up and flinch

(CR). The lack of this response during a car race suggests

stimulus discrimination may be present. Because neither

person has had an accident, higher-order conditioning may

account for their learning. Specifically, screeching tires (CS)

often give rise to mental images of accidents. These mental

images are already established CSs, providing the basis for the

CS-CR pairing.

More Examples of CC (spontaneous

recovery)..

5. Early in their relationship, mere presence of Donna excited

Jack. This gradually died out, however, as Donna behaved

tolerantly but indifferently. When the relationship ended, Jack

was bored with Donna and didn’t even think about her during

the next year. Now, he was surprised at how excited he was

becoming as he saw Donna laughing with her friends through

the window of a bus.



 The sight of Donna (CS) elicits romantic excitement (CR).

The response was extinguished when Donna failed to

stimulate her partner (the UR). The reaction one year later

suggests spontaneous recovery—the reappearance of the

conditioned response after an apparent extinction.

More Examples of CC (generalization)..



6. Bill couldn’t ever remember being so sick and nauseated. He

would never go to that restaurant again, and he would never

again eat chicken. All he could think about was the good

dinner his mother would prepare for his homecoming. As he

entered the kitchen, be became flushed and felt nauseated

when he saw the golden brown turkey sitting on the table.

 UCS – poisoned chicken

 UCR – being sick and nauseated

 CS – appearence of turkey

 CR – feeling nauseated

 In the example, stimulus generalization is taking place. Because turkey is

very similar to chicken, responses originally elicited by chicken are now

also elicited by turkey.

 Little albert example: fear of all the white fury object

Operant Conditioning

(B. F. Skinner)

 Is the organism passively learning associations

between neutral stimuli and important stimuli that

produce responses?



CLASSICAL

CONDITIONING



 Or is it learning associations between behaviors and

and their consequences?
