  1. Systematic desensitisation Learning Approach

  2. What is it? • It’s based on the assumption that psychological disorders are behaviours we have learnt through classical and operant conditioning • It focuses on changing abnormal behaviour rather than thought processes or biological causes • Aims to help a person unlearn the abnormal behaviour and replace it with a more suitable one.

  3. Process.. For example using treatment to overcome abnormal behaviour such as phobias, Treatment can take place over a number of sessions and can use either process of in vivo (exposure to real object) or in vitro (imaginary exposure to object). Uses four stages: 1) Functional analysis – questioning to discover anxiety/triggers for it 2) Anxiety hierarchy – both create a hierachy of anxiety provoking situations 3) Relaxation training – taught to relax using different methods 4) Gradual exposure – slowly introducing object

  4. Example of systematic desensitisation being used to treat acrophobia (fear of heights) http://www.youtube.com/watch?v=omYECykyQWE

  5. Evaluating the treatment.. • Effective with simple phobias such as a particular species of snakes • Treatment is considered to be more ethical than others based on classical conditioning e.g. Aversion therapy • Outcomes are easy to measure as goals are clearly specified before hand • Complex and social phobias don’t work as well and have high relapse rates, e.g. Fear of being in open spaces • Treatment only focuses on observable symptoms rather than deeper psychological ones. • Some therapists argue not all steps are needed for it to be successful, only exposure in itself is enough to be effective
