Behavioural explanations for phobias Flashcards
What is the two-process model?
Proposed by Mowrer (1947)
States phobias are acquired
(learnt in the first place) by classical conditioning and maintained by operant conditioning.
What is classical conditioning?
Learn to associate neutral stimulus with the unconditioned response which is fear.
Give an example of classical conditioning with phobias
Watson and Rayner (1920)
Little Albert = no anxiety at beginning
Made loud noise whenever rat was presented
UCS –> UCR
Rat now conditioned stimulus that produced conditioned response.
*** case study
What does stimulation generalisation mean?
Response extrapolated to anything that resembled the conditioned stimulus.
E.g: Albert displayed all signs of distress with fur coat/ non-white rabbit.
How does maintenance by operant conditioning work?
Reinforcement = repetition of behaviour.
Individual avoids unpleasant stimulus ~ reward is relief ~ behaviour repeated due to desirable consequence.
Reduction in fear reinforces avoidance behaviour so phobia is maintained.
Strength of explanation
Therapy
Real life application
Develop treatments —>
~Systematic desensitisation (unlearn fears through classical conditioning)
~Flooding (prevents people from avoiding their phobias and stops negative reinforcement from taking place)
Avoidance behaviour is prevented.
Successful in treating people with phobias = effective
Weakness for explanation
Biological preparedness
Not complete explanation for phobias.
Bounton (2007) –> Highlights evolutionary factors play role in phobias especially if avoidance of stimulus increase chances of survival
Idea we are predisposed to some phobias = innate not learnt
——–> act as survival mechanisms for ancestors
Innate predisposition called biological preparedness (Seligman 1971)
More to phobias than learning
Weakness for explanation
Ignores cognitive factors
Cognitive factors ignored because they cant be explained by behaviourist frameworks.
Phobias may develop as a consequence of irrational thinking.
Lead to cognitive therapies such as CBT
More successful than behaviourist treatments for social phobias (Engels et al 1993).
