1Learning is defined as a relatively permanent
change in behavior or knowledge that occurs as a
result of experience.
What is Learning???
2The 4 Factors That Form The Definition of
Learning
- learning is inferred from a change in
behavior/performance - learning results in an inferred change in memory
- learning is the result of experience
- learning is relatively permanent
- This means that behavior changes that are
temporary or due to things like drugs, alcohol,
etc., are not "learned".
3One type of learning is Classical
Conditioningaka Associational Learning
ConditioningLearning
4Classical Conditioning is learning that takes
place when an originally neutral stimulus comes
to produce a conditioned response because of its
association with an unconditioned stimulus.
5- Pavlov believed in contiguity - temporal
association between two events that occur closely
together in time. The more closely in time two
events occurred, the more likely they were to
become associated as time passes, association
becomes less likely.
6Diagram of Classical Conditioning
- Unlearned S-R
- UCS UCR
- (association formed/pairing made)
- CS CR
- Learned S-R
7Unconditioned Stimulus (UCS)
- It can be any stimulus that creates an
autonomic/automatic/reflexive response in an
organism - Examples anyone??????
8Unconditioned Response (UR)
- A UR can be any unlearned response that can be
elicited from an organism. - (note this word, elicit will be important)
- Examples anyone??????
- HR increasing
- Sweat
- Vomit/nausea
- Tears, etc.
9Conditioned Stimulus (CS)
- Anything that can be perceived (heard, smelled,
felt, seen, tasted) - Virtually anything can be paired up with a UCS to
become a CS.
10Conditioned Response (CR)
- Anything that can be a UCR/UR can become a CR.
- The UCR/UR is ALWAYS the same as the CR
11Diagram of CC-Lets look again
- Unlearned S-R
- UCS UCR
- (association formed/pairing made)
- CS CR
- Learned S-R
12Lets look at the diagramand some examples
13Little Albert Example of CC
- Unlearned S-R
- UCS UCR
- Loud Noise fear/crying
- (association formed/pairing made)
- Rat or Rabbit fear/crying
- CS CR
- Learned S-R
14Pavlovs Dog Example of CC
- Unlearned S-R
- UCS UCR
- Food presented dog salivating
- (association formed/pairing made)
- Bowl or steps dog salivating
- CS CR
- Learned S-R
15Remember that Little Albert generalized his fear
of rats into fear of anything with white fur,
including a Santa Claus mask, a rabbit, etc.
16Example of Classical Conditioning
- Unlearned S-R
- UCS UCR
- Flu Bug vomiting
- (association formed/pairing made)
- Restaurant of Choice vomiting
- CS CR
- Learned S-R
17Example of Classical Conditioning
- Unlearned S-R
- UCS UCR
- Sadness over breakup crying
- (association formed/pairing made)
- Song that meant a lot to relationship crying
- CS CR
- Learned S-R
18Example of Classical Conditioning
- Unlearned S-R
- UCS UCR
- No food/low blood sugar hunger pains
- (association formed/pairing made)
- Clock/particular time hunger pains
- CS CR
- Learned S-R
19Typically, the CS occurs slightly before the
UCS.There are types of conditioning that change
this order and overlappingits in a handout for
next time.
20Extinction
- A procedure that leads to the gradual weakening
and eventual disappearance of the CR - Involves repeatedly presenting the CS without
pairing it with the UCS
21Spontaneous Recovery
- Occurs when a previously extinguished CR
reappears after a period of no training. - Will often result from non-recognized factors not
previously identified
22Generalization
23Discrimination
24Classical Conditioning in Real World
- CC does occur in the real world as you no doubt
have figured out by now. The problem is the
overlap with operant conditioning. - We will examine Operant Conditioning next time in
Module 21.
25Examples from the Net
- If you have pets and you feed them with canned
food, what happens when you hit the can opener?
Sure, the animals come running even if you are
opening a can of green beans. They have
associated the sound of the opener with their
food.
26Examples from the Net
- Classical conditioning works with people, too. Go
to K-Mart and watch what happens when the blue
light turns on. Cost conscious shoppers will make
a beeline to that table because they associate a
good sale with the blue light. (And, the research
proves that people are more likely to buy the
sale item under the blue light even if the item
isn't a good value.) (note this is not TRUE
classical conditioning)
27Advertising
- Many beer ads prominently feature attractive
young women wearing bikinis. The young women
(Unconditioned Stimulus) naturally elicit a
favorable, mildly aroused feeling (Unconditioned
Response) in most men. The beer is simply
associated with this effect. The same thing
applies with the jingles and music that accompany
many advertisements.
28Crime reaction
- when a prof was in college he was robbed at gun
point by a young man who gave him the Choice
("Your money or your life.") It was an unexpected
and frightening experience. This event occurred
just about dusk and for a long time thereafter,
he often experienced moments of dread in the late
afternoons particularly when he was just walking
around the city. Even though he was quite safe,
the lengthening shadows of the day were so
strongly associated with the fear he experienced
in the robbery, that he could not but help feel
the emotion all over.
29An Auntie
- I liked my aunt, she always made me feel warm
and wanted. She always wore a particular perfume.
When I smell the perfume now, I immediately feel
warm and wanted.
30Another cat example
- In order to be able to punish my cat even when
I'm not near enough to reach him, I have paired
the sound of a clicker with getting squirted with
water. Now the sound of the clicker causes him to
startle. - The click is developing the same aversive
properties as the water through Classical
Conditioning. The Unconditioned stimulus is the
water the Unconditioned response is the "jump"
as in startle. The click starts our as a neutral
stimulus, but becomes the Conditioned stimulus
capable of producing the Conditioned "jump"
response.
31The smell of fresh bread baking makes my mouth
water.
- This is probably the result of Classical
conditioning. In the past the smell of the fresh
bread immediately preceded putting a piece in my
mouth, which causes salivation. Through the
mechanism of Classical conditioning the smell
itself comes to elicit salivation.
32After the bad car accident we had last year, I
cringe and break into a sweat at the sound of
squealing brakes.
- This is Classical conditioning. The cringing,
which is an unconditioned response to pain or
fear, was produced by the accident and its
accompanying pain. That accident was probably
preceded by the sound of squealing brakes, which
became a conditioned stimulus for the conditioned
response of cringing.
33Alcoholics 1
- To treat alcoholics, we sometimes put a chemical
in their drinks that makes them sick. Eventually
the taste of alcohol become aversive.
34Alcoholics 2
- Another way to treat alcoholics is to have them
take a drug called anabuse. If they ingest any
alcohol at all, the will have serious vomiting
issues. The desire is to pair the vomiting with
the alcoholic drink.
35- Anna learns to blink when she sees her father
hold the camera to his eye. - US
- UR
- CS
- CR
36- Mark has to get a shot once a week at the
doctor's office. The shots are somewhat painful,
and are administered by a nurse. Mark cringes
every time the nurse inserts the needle into his
arm. After a couple of weeks, Mark finds that he
is tense the minute the nurse walks in the room
to give him the shot - US
- UR
- CS
- CR
37- Rita was in a car accident on the interstate. She
did not get seriously injured but the accident
terrified her. Now she avoids the interstate,
because driving on it makes her too tense and
nervous. - US
- UR
- CS
- CR
38"fear of bridges"
- -fear of bridges can develop from many different
sources. For example, while a child rides in a
car over a dilapidated bridge, his father makes
jokes about the bridge collapsing and all of them
falling into the river below. The father finds
this funny and so decides to do it whenever they
cross the bridge. Years later, the child has
grown up and now is afraid to drive over any
bridge. In this case, the fear of one bridge
generalized to all bridges which now evoke fear.
39- Advertising - modern advertising strategies
evolved from John Watson's use of conditioning.
The approach is to link an attractive US with a
CS (the product being sold) so the consumer will
feel positively toward the product just like they
do with the US.
