Behavioural Explanations Of Phobias Flashcards
A01
The behavioural approach (behaviourism) analyses phobias based on external observations of environmental stimuli and behavioural responses (rather than e.g. the underlying thought processes). The two-process model explains how phobias are developed and maintained through behavioural conditioning.
The two-process model
The two-process model explains phobias as:
Acquired through classical conditioning, and
Maintained through operant conditioning.
Unconditioned stimuli’s is associated with a neutral stimulus, conditioned stimulus is formed
A01 Watson and rayner
In their experiment, an 11 month old baby – ‘Little Albert’ – was given a white rat to play with. Albert did not demonstrate a fear response towards the rat initially, but the researchers then made a loud noise which frightened Albert. This process was repeated several times, after which Albert demonstrated fear behaviour (e.g. crawling away, whimpering) when presented with the rat (and similar stimuli such as a rabbit and a fur coat) even without the loud noise.
Operant conditioning
operant conditioning occurs in response to behaviour, which is under a person’s control. If a person behaves in a way that produces a pleasurable outcome, then that behaviour is positively reinforced, making the person more likely to behave that way again. Similarly, if a person behaves in a way that reduces an unpleasant feeling, then that behaviour is negatively reinforced, also making them more likely to behave that way again.
Strengths of behaviourist explanations of phobias: A03
Supporting evidence: In addition to Watson and Rayner (1920) above, there are several case studies that support the behaviourist explanation of phobias. For example, King et al (1998) describe several case studies of children who acquired phobias after a traumatic experience.
Weaknesses of behaviourist explanations of phobias A03
Alternative explanations: Rather than focusing on behaviours, the cognitive approach explains phobias in terms of thought processes. For example, there is evidence that phobic people may have an attentional bias (i.e. disproportionate focus of thought) towards the scariest features of the stimuli (e.g. a dog’s teeth or a spider’s venom).
Weakness A03
Not everyone who has an unpleasant experience at the same time as a neutral stimulus goes on to develop a phobia. For example, a person who gets bitten by a dog will not always develop a phobia of dogs. This weakens the behaviourist claim that phobias are acquired through classical conditioning.
