5. How does reinforcement effect our
behaviour?
B.F Skinner studied how animals can learn from the
consequences of their actions.
He specifically focused on Reinforcement.
Reinforcement strengthens the likelihood of
behaviour re-occurring.
AO1 - To explore and understand Operant Conditioning.
6. Positive Reinforcement
Receiving a reward when a certain behaviour
is performed to make the behaviour happen
again - to behave the same way again in
order to receive the reward.
AO1 - To explore and understand Operant Conditioning.
7. Negative Reinforcement
Occurs when someone avoids something
unpleasant - something undesirable is
removed when the desirable behaviour
happens.
AO1 - To explore and understand Operant Conditioning.
8. Punishment
This is when something undesirable is
received after a behaviour to make it stop -
Punishment is used in an attempt to
decrease a behavior.
AO1 - To explore and understand Operant Conditioning.
10. B.F. Skinner claimed that
all behaviour is learnt as a
result of consequences in
our environment – operant
conditioning
This involves learning
through the consequences
(positive and negative) of
behavioural responses.

Operant Conditioning
11. Operant Conditioning
11/09/15
Operant conditioning is
concerned with the use of
consequences, such as
gaining rewards or receiving
punishments, in order to
modify and shape behaviour.
Skinner, like Pavlov, tested
this learning process on
animals

12. Operant Conditioning
He trained rats to press a lever using both types of reinforcement.
He used positive reinforcement to train the rat, by giving the rat a pellet of
food each time it pressed the lever.
This caused the rat to learn that the lever = food, so it continued to press the
lever.
He used negative reinforcement to train the rat, by running an electric current
through the floor of the cage.
When the rat pressed the lever, the electric shock would stop.
This taught the rat that lever = getting rid of something bad.
AO3 – To analyse the research surrounding Operant Conditioning.
13. Positive Reinforcement
Increases the likelihood of a response occurring because
it involves a reward for the behaviour
Can you think of any examples?
The worker gets paid a bonus for working hard.
The dog gets a treat for returning when called.
The child gets dessert for eating her vegetables (bribery!)
Reward points are given for good work.
Positive reinforcement
11/09/15 13
14. Negative Reinforcement
Increases the likelihood of a response
occurring because it involves the
removal of, or escaping from,
unpleasant consequences (e.g. it leads
to stopping or avoiding an electric shock)
Can you think of any examples?
The choke collar is loosened when the dog
moves closer to the trainer.
The reins are loosened when the horse
slows down.
The car buzzer turns off when you put on
your seatbelt.
The torture is stopped when the victim
confesses.

15. Operant Conditioning
11/09/15
It important to note however that the associations between responses and
consequences have to be made close together in time for learning to
occur.
Operant conditioning has been applied to the treatment of behaviour (e.g.
behaviour shaping)
Examples included social skills training for offenders, and token economy
systems used in institutions whereby tokens are given as a secondary
reinforcement for good behaviour.

18. What do you think of
Punishment?
AO1 – To discuss punishment within the Behaviourist Approach.
19. Examples of Positive Punishment
The consequence is receiving something
unpleasant which decreases the
probability of the behaviour being
repeated (e.g. the behaviour leads to an
electric shock or a smack)
Can you think of any examples?
The peeing on the rug (by a puppy) is
punished with a swat of the newspaper.
The driver's speeding results in a ticket
and a fine.
The baby's hand is burned when she
touches the hot stove.
Walking straight through low doorways is
punished with a bonk on the head.11/09/15 19
20. Examples of negative punishment
The consequence is removing
something desirable and decreases
probability of the behaviour being
repeated
Can you think of any examples of this?
Toys being taken away from a child
when they are throwing a tantrum
The child has his crayons taken away
for fighting with his sister.
The teenager is grounded for
misbehaviour (loses their social life)
Child banned from playing computer
games for swearing

21. B.F. Skinner’s views on Punishment:
Tells us what NOT to do…
doesn’t tell us what to do
Teaches us avoidance
May cause undesirable side effects:
Fear
Aggression
If punishment is unpredictable and unavoidable, we develop
sense that events are beyond our control
Leads to:AO1 – To discuss punishment within the Behaviourist Approach.
24. Behaviourist Perspective Case Study:
Derek - Operant Conditioning
Derek is 45 years old and attends a Day Centre for
adults with learning difficulties. The staff at the centre
find his behaviour challenging and unacceptable.
Derek often shouts out and demands attention and he
refuses to comply with the simplest of instructions that
all clients are expected to follow.
Describe how the staff at the Day Centre could use
operant conditioning to modify and change Derek’s
behaviour.
Consider the positives and negatives of Operant
Conditioning.

28. Strengths of approach
Behaviourism is very scientific. Theories are testable and
supported by rigorous experimental research – Uses the
experimental method helps to establish cause and effect,
objective
Replicable can be repeated due to high control so has
reliability
Mainly quantitative data easy to analyse
Behaviourist explanations can be applied to the real world to
explain everyday behaviour such as phobias and has produced
many practical applications
Useful applications to education, child rearing (i.e. super
nanny)
It provides strong counter-arguments to the nature side of the
‘nature-nurture’ debate
11/09/15 28
29. Limitations of approach
11/09/15 29
• Many forms of learning cannot be satisfactorily explained
by classical and operant conditioning e.g. insight learning
• Approach ignores important mental processes involved in
learning
Over simplified only takes into account nurture, rules
out any influence of anything else
Lack of ecological validity due to highly controlled
experiments issues with generalisability
Lack of qualitative data no thoughts or feelings known
Much data has been obtained from species such as rats,
dogs and pigeons but the relevance of these findings to
human behaviour is dubious. Can we extrapolate?
