Based on the idea that phobias are learnt through association to fear, so therapies attempt to replace the fear association with one of relaxation/calm
Gilroy et al. (2002) examined 42 patients with arachnophobia. Each patient was treated using three 45-minute systematicdesensitisation sessions. When examined three months and 33 months later, the systematic desensitisation group were less fearful than the control group (who were only taught relaxation techniques). This provides further support for systematic desensitisation, as a long-termtreatment for phobias.
Patients with phobias which have not developed through personal experience (classical conditioning), for example, a fear of heights, are not effectively treated using systematic desensitisation
Some psychologists believe that certain phobias, like heights, have an evolutionary survival benefit and are not the result of personal experience, but the result of evolution
There are ethical concerns as flooding exposes participants to emotional harm, and it could also end up reinforcing the phobia if treatment is ended too soon
Research has suggested that flooding is comparable to other treatments, including systematic desensitisation and cognition therapies, however, it is significantly quicker
Many patients do not complete their treatment because the experience is too stressful and therefore flooding is sometimes a waste of time and money as many patients do not finish their therapy
Although flooding is highly effective for simple (specific) phobias, the treatment is less effective for other types of phobia, including social phobia and agoraphobia
Some psychologists suggest that social phobias are caused by irrational thinking and are not caused by unpleasant experiences (or learning through classical conditioning). Therefore, more complex phobias cannot be treated by behaviourist treatments and may be more responsive to other forms of treatment, for example, cognitive behavioural therapy (CBT), which treats the irrational thinking
Both systematic desensitisation and talking therapies take a number of sessions to complete and require one on one time with the therapist, resulting in a substantially higher cost than for drug treatments
Watson and Rayner (1920) used little Albert to induce phobias in a child by making loud noises when presenting a white rat, generalising fear to other white fluffy objects
Menzies and Clarke (1993) found that only 2% of children with a fear of water could recall a traumatic experience with water, suggesting behaviourist explanation cannot account for all phobias
