Person with the phobia is immersed in the phobic experience in one long session. Continues until the patient's anxiety has disappeared.
Systematic desensitisation
Patient is taught relaxation techniques such as focusing on breathing.
Desensitisation hierarchy is created - where the individual is gradually introduced to the feared situation one step at a time, move onto the next stage once anxiety has gone. Goes from least to most feared stimuli.
Counterconditioning - taught a new association to counter the original one, taught through classical conditioning to associate the phobic stimulus with a new response of relaxation.
Evaluation of SD
+ Effectiveness - 75% respond to it, in vivo techniques are more effective. Must use range of different exposure techniques.
-Not appropriate for all phobias - doesn't treat phobias with an evolutionary survival component such as fear of the dark.
Evaluation of flooding
+Effectiveness - both SD and flooding are effective, flooding is better. It is also relatively quick compared to CBT.
-Individual differences - can be highly traumatic, patients may quit during the treatment which reduces effectiveness.
General evaluation of behavioural therapies
+Fast, cheap and require less effort. CBT requires willingness for people to think deeply about their mental problems which isn't true in behavioural therapies.
