A01 - ehaviourism is also known as learning theory
B
- Study behaviour that can be observed and measured, highly value empirical methods.
- Not concerned with mental processes
- Rejected introspection as it involved too many concepts that were vague and difficult to measure
- Behaviourists try to maintain control and objectivity within their research and rely on lab studies.
- Behaviourists believe behaviour is learnt.
- They describe a baby's mind as 'blank slate' (Tabula Rasa), and this is written on by experience.
lassical
C - lassical conditioning- learning through association
C
conditioning - - This stems fromPavlov'sdog, who, through classicalconditioning, began to salivate to the
Pavlov/ sound of the bell after pairing the sound with food
Watson & - Before conditioning:
Rayner - Unconditioned stimulus (UCS) = food
- Unconditioned response (UCR) salivation
- During conditioning:
- Unconditioned stimulus = food + bell
- Unconditioned response = salivation
- After conditioning: Conditioned stimulus (CS) = bell Conditioned response (CR) =
salivation
- Watson & Raynershowed that phobias in humans couldbe taught through classical
conditioning.
- They taught Little Albert to have a phobia of a white rat after they paired a rat with a loud
noise
- To start, Little Albert showed no fear of the white rat, but after several pairings, he
exhibited fear
- The phobia was then generalised to other white things, such as cotton wool and rabbits
(stimulus generalisation).
, perant
O - S kinnertaught rats to press a lever to get food inthe 'Skinner box'.
conditioning - - Firstly, touch the lever by accident and release a pellet of food.
Skinner - The rat learns to press the lever quickly to get lots of food
- Skinnertested variable reinforcement where food wasdispensed using different ratio
schedules
- e.g. 1:5 a food pellet was dispersed every 5th lever press
- He discovered that unpredictable reinforcement was more successful for conditioning
behaviour than continuous reinforcement.
- This is the same principle as playing fruit machines.
- Our behaviour is shaped by its consequences.
- Positive reinforcement- encourages behaviour to berepeated and strengthens behaviour
through rewards,e.g. merits and house points at school.
- Negative reinforcement- encourages behaviour becausea negative condition is
punished.e.g. a child being caned for doing a negativeaction/ behaviour
- Punishment decreases- There is a chance of behaviourbeing repeated as children who
are punished often simply find ways to avoid detection and punishment rather than
changing their behaviour.
- Similarly, a child with bad behaviour, may continue as they are being positively reinforced
with attention.
A03 nimal studies
A - S kinner’sresearch on rats has faced criticisms regardingits generalisability to human
- behaviour.
generalisability - Critics argue that the controlled environment of theSkinnerBox and the use of rats as
issues subjects may not fully capture the complexity of human behaviour.
- The research does not address the nuances of human decision-making and behaviour.
- Human actions are influenced by a range of factors, including emotions, social context,
and cognitive processes that were not represented inSkinner’sexperiments with rats.
- Consequently, this raises questions about the extent to which findings from rat studies
can be generalised to human behaviour.
Scientific - strength of behaviourism is that it focuses on studying phenomenon which are
A
observable and measurable.
- E.g.Skinnerproved that a rat could learn throughpositive reinforcement, as the
introduction of food showed a direct change in the rat’s behaviour i.e. pushing a lever.
- Having observable behaviour to support a theory is a strength because it allows
researchers to understand behaviour objectively.
- The behaviourist approach places importance on scientific processes such as replication
and objectivity, which has helped improve the credibility and status of psychology, helping
to establish it as a science.
Deterministic - ne weakness of the behaviourist approach is that it is highly deterministic.
O
- For example,Skinnerhimself said that free will isan illusion.
- In addition, in his experiment, he showed that the rat’s behaviour of pulling the lever was
a direct result of the reinforcement.
- This demonstrates environmental determinism as it sees all behaviour as being
determined by past experiences and conditioning.
- As a result, we cannot be certain that the approach gives us an accurate and varied
explanation of human behaviour, which accounts for the impact of free will.
eal-life
R - T wo treatments for phobias, systematic desensitisation and flooding, are based upon the
application idea of classical conditioning and have been successful in helping individuals overcome
their irrational fear by forming a new association with the stimulus.
- This shows that behaviourism is useful because it highlights how the principles of
conditioning have been successfully applied to a broad range of real-world behaviours.
- Consequently, this theory has been shown to have positive implications within society,
improving people’s well-being and helping them to manage their future behaviours
positively.
