Unit 1.4: Phobias

key terms

    phobias

Typical behaviour: a behaviour that is expected, and considered to be normal

Atypical behaviour: a behaviour considered abnormal, usually a minority of people

Phobia: an atypical fear response given the object or situation

Agoraphobia: An extreme fear of being in public spaces away from the safety of home

School phobia: an extreme fear of attending and being in school

Social phobia: an extreme fear of being exposed or embarrassed during social contact

Acrophobia: an extreme fear of heights

Arachnophobia: An extremem fear of spiders (most common animal phobia)

core theory

Learning by association – people learn to associate a particular response with a particular stimulus

Based on Pavlov’s dog experiment

When the food is presented (Unconditioned Stimulus) the dog salivates (Unconditioned Response)

The food (US) is then paired with a bell (Neutral Stimulus) and the dog still salivates because the food is there (Unconditioned Response)

In time, the dog will salivate with the noise of the bell alone. The bell becomes a Conditioned Stimulus and the salivation is now a Conditioned Response – the dog has learnt that the bell means food will come so starts to salivate.

classical cond1

Can be generalised to other similar stimuli

Extinguished (got rid of) over time, usually when fear is ‘faced’

crits of core

  • Behaviourist theory ignores the mind and the thinking behind the behaviour
  • Behaviourist theory assumes we need direct experience with the feared object – some others argue we can learn it indirectly
  • Behaviourist theory cannot explain the idea that some people have phobias of objects they have no direct or indirect experience of
  • Behaviourist theory can be tested scientifically and reliably in lab experiments
  • Behaviourist theory can be used to treat phobias by removing them through positive associations

alternative

  • PHOBIAS – fear is instinctive because it helps us to survive.
  • If we had no fear, we would put ourselves in dangerous situations that could kill us
  • Evolutionary theory
    • would argue that certain objects or situations are more threatening to our survival than other
    • would also say we are more likely to fear animals least like ourselves in shape and form

 

  • Evolutionary theory does not say we are born with their phobias
  • It says we are born with a biological preparedness to fear certain things more than others as they are a greater threat to our survival

core study

Aim: Studied classical conditioning of fear of a white rat using ‘Little Albert’ 9 month old baby

Procedure:Tested for reactions to neutral stimuli

–live animals, burning newspaper, cotton, human masks No fear to these

When Albert reached for a white rat (NS) they banged a steel bar behind the baby to make a loud noise (US) and scare him (UR).

Results

After seven pairings the rat was enough to frighten Albert even though it had not done so before.

Five days later, fear was tested again-still persisted. Albert was also afraid of a rabbit, a dog, a sealskin coat(fluffy), a Santa mask and even Watson’s hair (which was white)

Ten days later – some fear still there. One month later – mild fear, and Albert’s mother withdrew him

Conclusions: You can condition fear into a human using classical conditioning, and the fear can be generalised to similar objects.

crits of core study

Generalisability: Small sample size of only one child – hard to generalise outside of this sample

Reliability: Well structured and controlled experiment, although no direct video evidence of the conditioning, so hard to replicate easily

Application: This can be used to develop phobia therapies, by pairing the stimulus with a positive experience to form new associations

Validity: Ecologically not very valid, as a lab experiment, although Albert was used to being in the hospital nursery as his mother worked there.

Ethics: Very bad ethically – it caused a great deal of distress to Albert, causing harm to the participants. His mother did withdraw him from the experiment, however W&R didn’t remove the fear before this, which is unethical.

applications

One application is to treat phobias using systematic desensitisation. The person with a phobia develops an anxiety hierarchy that describes situations with the thing they are scared of, ranging from low to high in terms of their fear rating. An example is seen below:

Bit by bit they work up the pyramid, practising their relaxation techniques and eventually conquer their fear.
