2Chapter 3 Behaviorism and Classical Conditioning
- Basic Asssumptions
- Equipotentiality.

3Chapter 3 Behaviorism and Classical Conditioning
- Classical Conditioning (a.k.a. signal learning)
Pavlov - Russian physiologist who initially was studying
digestion - Used dogs to study salivation when dogs were
presented with meat powder - Also known as Pavlovian or Respondent
Conditioning - Reflex Automatic, nonlearned innate
- response e.g., an eyeblink
4The classical conditioning procedure.
5Principles of Classical Conditioning
- Expectancy Expectation about how events are
interconnected - Acquisition Training period when a response is
reinforced - Extinction ________ of a conditioned response
through removal of _____________ - Spontaneous Recovery ____________ of a learned
response following apparent extinction
6 of
- Principles of Classical Conditioning
- Expectancy Expectation about how events are
interconnected - Acquisition Training period when a response is
reinforced - Spontaneous Recovery Reappearance of a learned
response following apparent extinction - Stimulus Generalization A tendency to respond to
stimuli that are similar, but not identical, to a
conditioned stimulus (e.g., responding to a
buzzer or a hammer banging when the conditioning
stimulus was a bell) - Stimulus Discrimination The learned ability to
respond differently to various stimuli (e.g.,
Paula will respond differently to various bells
(alarms, school, timer))
Chapter 3 Behaviorism and Classical Conditioning
7Chapter 3 Behaviorism and Classical Conditioning
- Higher order conditioning
- Includes combining an NS to an already
established CS. - Sensory Preconditioning test anxiety
8Chapter 3 Behaviorism and Classical Conditioning
- Extinction Weakening of a conditioned response
through removal of reinforcement - Problems with the use of extinction.
- The speed of extinction is ___________.
- Due to second order conditioning, there may be
many associated variables. - Difficult to extinguish all of the tem.
- Spontaneous recovery.
- Due to avoidance of feared stimuli, people may
not get a chance to unlearn the conditioned
response. - Alternatives
- Counterconditioning of more _________ responses.
9Chapter 3 Behaviorism and Classical Conditioning
- Educational Assumptions
- How do you get to Carnegie Hall? Practice,
practice, practice or exposure, exposure,
exposure. - The academic setting should be a positive and
pleasant environment. - To break a bad habit, replace one S - R with an
more desirable S R. - Exhaustion method.
- Threshold method.
- Incompatibility method.
- Assessment of learning involves the observation
of behaviors.
10Chapter 4 Operant Conditioning
11Chapter 4 Operant Conditioning
- B.F. Skinner (1938)
- A response that is followed by a reinforcer is
strengthened and therefore more likely to occur
again. - Reinforcer a stimulus or event that increases
the frequency or likelihood of a response it
follows. - Instrumental/ Operant Conditioning
- Reinforcer follows the response (immediately).
- Reinforcer is contingent on the response.
- How is this different than Classical
Conditioning?
12Chapter 4 Operant Conditioning
- Primary Reinforcer Nonlearned and natural
satisfies biological needs (e.g., food, water,
affection) - Secondary Reinforcer Learned reinforcer (e.g.,
money, grades, approval) - Positive Reinforcement When a response is
followed by a reward or other positive event - Negative Reinforcement When a response is
followed by the _______ of an unpleasant event
(e.g., the bells in Fannies car stop when she
puts the seatbelt on) or by an ____ to discomfort
(escape behaviors).
13Chapter 4 Operant Conditioning
- Intrinsic Reinforcer
- Extrinsic Reinforcer
- Positive Feedback
- Social Reinforcer?
- Problems with each?
14Chapter 4 Operant Conditioning
- Punishments Any consequence that reduces the
frequency of a target behavior - Positive Punishment/ Punishment I
- Negative Punishment/ Punishment II
- Restitution
- Restitution Overcorrection
- Positive practice overcorrection
- Time out
- In-house suspension
15Chapter 4 Operant Conditioning
- Punishments/ Discipline
- Any punishment should
- Be _______ to the behavior
- Be ________ in strength to modify behavior
- Indicate the desired behavior
- Be immediate consistent
- Convey ______
16Chapter 4 Operant Conditioning
- Punishments which may be innappropriate.
- Physical and psychological punishment
- Social isolation (i.e. missing recess, going to
the corner of the room, suspensions etc) - Extra coursework
17Chapter 4 Operant Conditioning
- Other Instrumental Conditioning Issues
- Shaping - Molding responses gradually to a
desired pattern - Successive Approximations Ever-closer matches
- Extinction
- Antecedents
- Operant Stimulus Generalization Tendency to
respond to stimuli similar to those that preceded
operant reinforcement. How can this lead to
superstitions? - Operant Stimulus Discrimination Occurs when one
learns to differentiate between the stimuli that
signal either an upcoming reward or a nonreward
condition. - Cueing
- Setting Events
18Chapter 4 Operant Conditioning
- Instrumental Conditioning Schedules
- Definition Reinforcers do NOT follow every
response - Schedules of Reinforcement Plans for determining
which responses will be reinforced - Continuous Reinforcement A reinforcer follows
every correct response - Partial Reinforcement Effect Responses acquired
with partial reinforcement are very resistant to
extinction
19Chapter 4 Operant Conditioning
- Instrumental Conditioning Schedules
- Fixed Ratio Schedule (FR) A set number of
correct responses must be made to obtain a
reinforcer. - Variable Ratio Schedule (VR) Varied number of
correct responses must be made to get a
reinforcer. - Fixed Interval Schedule (FI) The first correct
response made after a certain amount of time has
elapsed is reinforced produces moderate response
rates. - Variable Interval Schedule (VI) Reinforcement is
given for the first correct response made after a
varied amount of time
20Chapter 5 Applications of Conditioning
21Chapter 5 Application
- Using Reinforcement
- Specify the desired or terminal behavior.
- Use extrinsic reinforcement only when the desired
behavior is not already present. - Identify truly reinforcing consequences.
- How do you know?
- The gain has to be greater than the loss
(sufficient strength). - Clearly describe the relationship between
behavior and consequence. - Be consistent.
- Gradually shape the more complex behaviors.
- When publicly awarded, make sure all individuals
have the potential to earn the reinforcement. - Use objective criteria to measure performance
(Merit Club). - Foster the ability to delay gratification.
- Gradually wean learners off the reinforcement
when the terminal behavior occurs regularly.
22Chapter 5 Application
- Decreasing undesirable behaviors
- Extinguish the response.
- Present noncontingent reinforcement.
- Reinforce other/opposite behaviors.
- Using punishment/ discipline.
23Chapter 5 Application
- Using Punishment
- Choose a punishment with sufficient strength
without being overly severe. - How do you know?
- The loss has to be greater than the gain
(sufficient strength). - Clearly describe the behavior to be punished and
the relationship between behavior and
consequence. - Be consistent.
- Be immediate whenever possible.
- Apply with an attitude of caring (unconditional
regard). - Explain or reassert why the behavior is
inappropriate. - Modify the environment when possible to reduce
tempting behavior. - Teach more appropriate responses (skill
streaming).
