CHAPTER
When we think
of learning, we
most often think
of the formal
type that occurs
in school.
Learning, however, takes place
continuously
every day.

Learning

Four Types of Learning
1
classical conditioning - making unavoidable
physical associations
2
operant conditioning - learning caused by the
consequences of actions we perform
3
social learning - learning that results from
watching other people
4
cognitive approach- learning that emphasizes the
rational and problem-solving thought processes

Pavlov and
Classical Conditioning
Classical conditioning can be defined as what
happens when a neutral stimulus evokes a
response that was originally produced by another
stimulus.
Pavlov would later win a Nobel Prize for his
work on the digestive system of dogs.
An illustration of Pavlov’s classic experiment
appears on the next slide.

Mary Cover Jones
Mary Cover Jones used an early form of
desensitization to prove that fears (phobias) could
be unlearned.
Peter, a young boy, had an extreme fear of
rabbits. Jones gave Peter his favorite food
while slowly bringing the rabbit closer and
closer. Eventually Peter no longer panicked
around rabbits.

Variations Within
Classical Conditioning
Stimulus Generalization
A response can be generalized to other like stimuli.
Extinction
If a stimulus is never reinforced, then the response
will go away.
Spontaneous Recovery
After extinction, a response will suddenly reappear.

B.F. Skinner and
Operant Conditioning
Operant conditioning can be defined as a behavior that is
learned (or avoided) as a result of its consequence.
Reinforcement is a key
component. If the behavior is
followed by a pleasurable
response, then the behavior
will reoccur. (I tell a joke…
people laugh…I tell the joke
again to a different group of
people.)

Operant Conditioning Processes
Primary Reinforcement is unlearned and
usually necessary for survival. Food is the best
example of a primary reinforcer.
Secondary Reinforcement is anything that comes to
represent a primary reinforcer such as praise from a
friend or a gold star on a homework assignment.
Punishment weakens a
response by following it
with something
unpleasant.

Generalization is a behavior
that spreads from one
situation to a similar one. (A
baby will call Daddy “Dada.”
When the baby sees any man,
the baby calls out “Dada.”)
Discrimination is the reverse of generalization.
Some stimuli have pleasant consequences and
some do not. (A baby gradually learns that
only one person responds with a smile when
called “Dada.”)

EXIT
Extinction occurs when a response is no longer followed
by reinforcement so that a person will gradually stop
making that response. (Tell a joke. If people do not
laugh, you’re not likely to tell the joke again.)
In shaping, successively closer
versions of a desired response are
reinforced (as in learning to play
tennis).
In chaining, each part of a sequence is reinforced; the
different parts are put together into a whole (as in
learning the steps to a dance).

Do you want to stop a
bad habit?
Wear a rubber band
around your wrist.
Every time you engage in
the bad habit, snap the
rubber band!

Schedules of Reinforcement
Variable Ratio
A person must perform different
(variable) acts before
reinforcement is given. (Children
in a school band selling candy have
to ask every person because they
don’t know who might buy the
candy.)
Fixed Ratio
The number of responses and reinforcement never varies. A
dentist gets paid according to how many cavities are fixed.

EXIT
Variable Interval
The amount of time varies
between reinforcements.
Performance is steady but
sluggish. (A person goes
fishing and is waiting for the
fish to bite.)
Fixed Interval
A set amount of time goes by before the
reinforcement occurs. Performance is irregular
and increases only before the reinforcement. (A
worker gets paid every two weeks.)

Albert Bandura and
Social Learning
According to Bandura, we imitate the activities
and behaviors of those around us. Between the
stimulus and the response is the “inner person.”
Much social learning is
observational. Children model
their behavior after watching.

Cognitive Approach
This approach emphasizes abstract and subtle
learning that could not be achieved through
conditioning or social learning alone.
Some learning is not intentional, but occurs
almost accidentally—a situation called latent
learning.
Expectancies are beliefs about our ability to
perform an action and to get the desired
reward. Expectancies affect learning.

Cognitive Maps
E.C. Tolman argued that animals and people use
cognitive maps to figure out where they are in the
environment. He showed that they use strategies
to analyze and (sometimes) to communicate
information.
