- SD is a behavioural therapy designed to reduce phobic anxiety through classical conditioning
- There are 3 processes involved in SD:
1. The anxiety hierarchy - Put together by client and therapist. Its a list of situations linked to the phobic stimulus that provoke anxiety arranged in order from least to most frightening
2. Relaxation - Therapist teaches client to relax as deeply as possible. It's impossible to be afraid and relaxed at the same time, so one emotion prevents the other (reciprocal inhibition). Clients might be taught meditation and it might involve breathing exercises.
3. Exposure - Client is exposed to phobic stimulus while in a relaxed state. Takes place across several sessions. Treatment is successful when the client can stay relaxed in situations high on the anxiety hierarchy
- Flooding is notunethical per se but it is an unpleasant experience so it is important that clients give fully informedconsent to this traumatic procedure and that they are fully prepared for it
- A client would normally be given the choice of systematicdesensitisation or flooding
- This may be due to the lack of option of avoidance behaviour, so the client learns that the phobic stimulus is harmless
- In CC, this process is called extinction
- A learned response is extinguished when the CS (e.g a dog) is encountered without the UC (being bitten)
- The result is that the CS no longer produces the CR (fear)
- In some cases the client may achieve relaxation in the presence of the phobic stimulus simply because they become exhausted by their own fear response
- Confronting ones phobic stimulus in an extreme form provokes tremendousanxiety
- Schumacher et al (2015) found that participants and therapists rated flooding as significantlymore stressful than SD
- This raises the ethical issue for psychologists of knowingly causing stress to their clients, although this is not a serious issue provided they obtain informed consent
- More seriously, the traumatic nature of flooding means that dropoutrates are higher than for SD
- This suggests that, overall, therapists may avoid using this treatment
