Behavioural explanations of phobic disorders
Behavioural explanations of phobic disorders state that fears can be conditioned through both classical and operant conditioning. For example, fears are acquired when a person associates a previously neutral stimulus with a fear response, such as in the case of Little Albert (Watson and Raymer, 1920). In this instance, the unconditioned stimulus was the loud noise, and the unconditioned response was the fear response. However, Watson and Raymer conditioned a fear of a fluffy white object, which then became a conditioned stimulus, leading to a conditioned response. The same process can explain why a person develops a phobia of dogs after being bitten by a dog: they associate the fear of being bitten, and pain (an unconditioned stimulus) with the dog (a conditioned stimulus) and so develop a fear of dogs.
However, operant conditioning can also explain one's phobic response. Mowrer (1947) proposed a two-step process by which people acquire phobias. The first is classical conditioning, and the acquisition of a phobia through association, but this is then supplemented with the process of operant conditioning. A person's avoidance behaviour of a phobic stimulus leads to a lack of anxiety, or a reduction in anxiety; this is reinforced through the process of negative reinforcement. Furthermore, the avoidance behaviour leads to no anxiety experienced from the phobia, which is positively reinforced.
Social learning theory can also be utilised in order to explain the acquisition of phobias. Social learning theory purports that phobias are acquired through the process of modelling, that is, learning behaviour from observing behaviour. For example, a child might see a parent show a fear response to a spider, and hence acquire a phobia because such a behaviour appears rewarding (i.e. the person gets attention).
