Believes people/animals learn to
behave in response to their
environment; Either by Stimulusresponse or reinforcement

Learning stimulus-response units of
behavior as a result of association

Anything in an environment that one can
respond to.

in behavior due to
experience

Classical Conditioning: Task #2

Pavlov’s Dog story

Pavlov began by ringing a bell around a dog
with no response. He then presented the dog
with a bowl of food which caused the dog to
begin to naturally salivate. He then rang the
bell and presented food together; salivation
occurred but b/c of the food. He continually
repeated this process until the dog began to
associate the bell with the food which would
then cause salivation. He can now ring the
bell w/out food and the dog will salivate.

Personal Example: Task #3

Figure out NS, UCS, UCR, CR, CS, and
acquisition point.
 When I first got to Concordia I was showering
once when I heard someone yell “flush!” I did
nothing and then suddenly I was nailed with
scorching hot water. Again I was showering
and heard someone yell “flush” and again I
was scorched with hot water. After a few more
times with the same outcome I heard the word
flush while showering and jumped out of the
shower.

 Programmed Learning

B.F. Skinner
Developed
idea of
reinforcement and helped
establish Behaviorist
approach, as well as
operant conditioning
Omission Training

Procedure that involves withholding
reward following a particular response or
action.

Example:
Come home late and lose car privileges
 Speed and lose personal money

Punishment

practice of imposing something
unpleasant or aversive on a person or
animal, usually in response to
disobedient or morally wrong behavior to
discourage its repetition
Cussing = soap in the mouth
 Detention for talking back in class

Positive Reinforcement
 Use
of a reward in learning,
encouraging repetition of that
behavior
 Example
 Candy
for good/correct answers
Operant Conditioning
Learning behavior, and is influenced
by reward or unpleasant
consequence after that behavior.
Negative Reinforcement
 Use
of unpleasant consequence
in learning process
 Example
 Study
to avoid failing test
 Obey law to avoid jail
 Eat to avoid starvation
Shaping
Reinforcement of different steps
towards the desired behavior
Shaping
Op. #2
FR
Reward is given after a fixed
number of positive responses;
not just one.
Fixed Ratio reinforcement schedule
Op. #2
FI
Reward is given if a desired
behavior happens w/in a
particular period of time
Fixed Interval Reinforcement
Op. #2
Implosion Therapy
Behavior therapy where someone with a
phobia is directly exposed to the feared
stimulus until it disappears
Implosion Therapy
Systematic Desensitization

Type of behaviour therapy, where for example a the
person's phobia is broken down into the discreet S-R
units that make it up. These are ranked from least
stressful aspect, to most stressful aspect. The
therapist works though each S-R unit helping the
person to replace each dysfunctional response of
being afraid, with a more functional response of feeling
relaxed.
Behavior Therapies

A category of therapies based upon
Pavlov's theory of classical conditioning.
Includes Systematic Desensitization,
Implosion Therapy, and Aversion
Therapy
Aversion Therapy
Purpose is to replace a pleasant
stimulus-response association
with an unpleasant association
Aversion Therapy
Behavior Modification

Therapies based on Operant
Conditioning. Includes the Token
Economy, and Programmed Learning.
Behavior modification concerns the use
of reward in the learning process.
Token Economy

Involves the use of a reward in areas like
prisons, psych wards, group homes,
which is exchanged by the recipient for
goods, services etc. The reward or token
is only given for desired behaviors.
Programmed Learning

Programmed learning applies the principles of
operant conditioning to the learning
experience. Used in flexi-learning; distance
learning; computer-based learning etc, what is
to be learned is divided up into small chunks,
or units. Your reward is passing a unit, which
allows you to then progress onto the next one.
Each unit is a wee bit more difficult than the
one that came before.
