Psychopathology L6 - The Behavioural Approach To Explain Phobias: Classical And Operant Conditioning And The Two Process Model Flashcards
What does the behavioural model suggest - by Mowrer
All behaviour (including phobias) can be learnt
People who have an abnormality can learn negative behaviour
What makes up the two process model
1) The phobia is learnt by classical conditioning or social learning
2) The phobia is maintained by operant conditioning
How does classical conditioning work
Method of learning that builds up an association between two different stimuli so learning takes place
E.g.
- White rat (neutral stimulus with no initial reaction) is presented to a person by itself
- Loud banging noise (unconditioned stimulus) is presented which makes the person cry/emotional response on its own
- repeatedly pair the two stimuli together many times until classical conditioning and learning takes place - will have emotional response when hear noise and see rat
- then present white rat alone (conditioned stimulus) and the person will have an emotional response (conditioned response)
- learning has taken place via classical conditioning and an association has been established
Classical conditioning case study
- little Albert study - 11 month old boy
- used white rat and struck steel bar with hammer
- 3x a week for 2 weeks (6 times in total)
Generalisation meaning
The tendency to transfer a response from one stimulus to another that’s similar
E.g. scared of white fur coat due to fear of white rat

Criticism of behavioural model
Not reliable study
- The study on Little Albert can be criticised because it was only conducted once and the findings have not been repeated (not very reliable)
- Therefore it could be questioned whether the same results would be gained if this study was to be repeated when investigating whether phobias can be learnt via classical conditioning
- The study could not be repeated nowadays due to ethical concerns
Case studies (classical conditioning) - evaluation point
- King (1998) supports the ideas proposed by classical conditioning
- From reviewing case studies he has found that children acquire phobias by encountering traumatic experiences with the phobic object e.g. children who have got bitten by a dog, might develop a phobia of dogs.
Traumatic experience
- A disadvantage of classical conditioning is that some people do have a traumatic experience such as a car accident
- However, many people do not then go on to develop a phobia (e.g. of cars/driving), so classical conditioning does not explain how all phobias develop
- The opposite is true for some phobias, some people are scared or an object, but they have not had a negative experience or even encountered the object before e.g. snakes
Criticism of behavioural model
- The psychologist Menzies criticises the behavioural model, especially the idea of classical conditioning
- He studied people that had a phobia of water (hydrophobia), and he found that only 2% of his sample had encountered a negative experience with water (due to classical conditioning)
- Therefore, 98% of his sample had a phobia of water but had never had a negative experience involving water, which means that they had not learnt to become frightened of water via classical conditioning.
- Therefore; how did these people get their phobia of water if they had not learnt it? Other findings include 50% of people who have a dog phobia have never had a bad experience involving a dog, so therefore learning cannot be a factor in causing the development of the phobia
Social Learning Theory/Modelling
- This is based on observational learning whereby young children might observe a reaction that their parents or family have to a particular situation, and the child will copy this behaviour
E.g. if we watch someone have a traumatic experience for instance they get bitten by a dog and start screaming, then we might imitate this behaviour and also become scared of dogs, which means we develop a phobia by observational learning. - The psychologist Minneka found that when one monkey in a cage showed a fear response to snakes, the other monkeys in the cage copied this response and also showed a fear response to snakes too.
- This example can be applied to humans.
Operant conditioning
- This method involves learning a new response (phobia) that can result in reinforcement
- Operant conditioning helps to explain how phobias can be maintained.
- Negative reinforcement: For instance if someone is scared of snakes, they will try to avoid snakes in order to reduce the risk that they will feel fear.
- Positive reinforcement: By avoiding snakes and not feeling fear, this is rewarding. Therefore the avoidance of snakes continues.

Limited model
- The behavioural model/two process model is limited as it ignores other factors that could cause phobias
- The Behavioural model focuses on learning and the environment, but would not take into account biological or evolutionary factors that could cause phobias
- Some people might have more of a genetic vulnerability to develop phobias than others and the behavioural model would ignore this
Doesn’t t explain adults
- Social learning theory can be successful in explaining how learning a phobia can occur in animals and young children
- However, social learning theory is not very strong in explaining how adults can learn to have phobias
- Therefore the behavioural model is limited to only explaining learning in young children and animals only
