behavioural approach to explaining phobias Flashcards
1
Q
Phobia
A
A type of anxiety disorder usually defined as a persistent fear of an object or situation, the effected person will go to great lengths to avoid typically disproportional to the actual danger posed by
2
Q
Behavioural approach
A
- emphasises the role of learning in forming behaviours
- avoidance, endurance, panic
- Mowrer proposed a two-process model: classical conditioning and operant conditioning
3
Q
Classical conditioning of phobias
A
- learning to associate something we have no fear of (NS) with something that already triggers a fear response (UCS)
4
Q
Watson and Raynor
A
- little Albert case study
- rat paired with loud noises
- rat becomes associated with the noise and fear of rats occur
- was then generalised to similar objects: all white things
5
Q
Maintenance by operant conditioning
A
- responses acquired by classical conditioning tend to decline overtime, but phobias are often long lasting
- mowrer suggested that phobias continued because of operant conditioning
- operant conditioning takes place when behaviour is reinforced/punished
- negative + positive reinforcement increases frequency of a behaviour
- in negative reinforcement an individual avoids a situation that is unpleasant, results in desirable consequences so the behaviour will be repeated
- therefore, mowrer suggested when we avoid a phobic stimulus we escape the fear and anxiety we would have suffered if we had remained
- this reduction in fear reinforces avoidance behaviour so the phobia maintained
6
Q
Strength: good explanatory power
A
- goes beyond purely classical conditioning and links to operant conditioning showing how phobias occur and have they are maintained
- important in treating phobias with therapy as it explains why patients need to be exposed to feared stimulus (gradual or flooding)
- prevention of avoidance behaviour causes the behaviour to stop being reinforced so phobia gradually declines
7
Q
Limitation: alternative explanation of avoidance behaviour
A
- not all avoidance behaviour associated with phobias are a result of anxiety reduction (agoraphobia)
- evidence that some avoidance behaviour motivated by positive feelings (safety)
- motivating factor to not leave house is not to avoid phobic stimulus but ti stay in safety
- hence why some agoraphobics can leave house with little anxiety if with trusted person, but not alone
- shows flaw in 2 process model that assumes avoidance is motivated by purely anxiety reduction
8
Q
Limitation: an incomplete explanation
A
- evolutionary factors?
- past of avoiding dangerous, biological preparedness = innate predisposition to acquire such fears
- some phobias don’t follow trauma? Cognitive aspects? Social learning theory of modelled emotions?
