SD is time-consuming, when compared to alternatives such as flooding, as the person with the phobia needs to be trained in relaxation techniques and gradual exposure can take many sessions
Progress in SD therapy may not generalise outside of the clinical setting when the person with the phobia must face their fear without the support of the therapist
SD is a behavioural therapy used to reduce phobic anxiety through the principle of classical conditioning
Learn to relax in the presence of the phobic stimulus then they will be cured
A new response to the phobic stimulus is learned (phobic stimulus is paired with relaxation instead of anxiety)
There are three processes involved in SD: anxiety hierarchy, relaxation, exposure
