6. Behavioural Approach To Treating Phobias Flashcards
What are the two behavioural therapies for treating phobias?
Systematic desensitisation and flooding
what is systematic desensitisation?
a behavioural therapy designed to gradually reduce phobic anxiety through the principle of classical conditioning
central idea of SD
if the sufferer can learn to relax in the presence of the phobic stimulus they will be cured
how is counterconditioning involved in SD?
a new response to the phobic stimulus is learned by pairing it with relaxation instead of anxiety
what is reciprocal inhibition (SD)?
it is impossible to be afraid and relaxed at the same time so one emotion prevents the other
what are the 3 processes involved in SD?
anxiety hierarchy, relaxation, exposure
what does the first stage of SD involve?
anxiety hierarchy is put together by patient and therapist which is a list of situations related to the phobic stimulus that provoke anxiety arranged from least to most frightening
what does the second stage of SD involve?
relaxation methods are taught to the patient which may involve breathing exercises, meditation, or mental imagery techniques. Alternatively, Valium can be used to relax
what does the third stage of SD involve?
the patient is exposed to the phobic stimulus which takes place over several sessions as they work up the hierarchy. When the patient can remain relaxed in the presence of lower levels of the phobic stimulus they move up the hierarchy
when is SD treatment successful (linked to the last stage)?
when the patient can stay relaxed in situations high on the anxiety hierarchy
what is flooding?
a behavioural therapy involving immediate exposure to a very frightening situation without a gradual build-up in an anxiety hierarchy
how long are typical flooding sessions?
longer than SD sessions, typically 2-3 hours
how does flooding work?
through extinction: stops phobic responses very quickly because without the option of avoidance the patient learns the phobic stimulus is harmless
how does the process of extinction occur in flooding?
learned response is extinguished when the CS (e.g. dog) is encountered without the UCS (e.g. being bitten), the result is that the CS no longer produces the CR of fear
how are ethical safeguards employed in flooding?
flooding is an unpleasant experience so it is important that patients give fully informed consent and that they are prepared
