Transcript

  • 1. Aversion therapy• An aversion is a complete dislike for something (rather than an allergy)• Aversion therapy is a form of behavior therapy that uses the principles of classical conditioning in which an aversive stimulus (e.g. nausea inducing drug) is paired with a maladaptive behaviour in order to reduce or eliminate that behaviour
  • 2. Aversion therapy• Used for treating• Homosexuality• Sexually deviant children• Addictions e.g. Smoking, alcoholism• Bad habits
  • 3. Aversion therapy• E.g. Smokers given electric shocks (UCS) when they see/ smell a cigarette (originally the NS) i.e. cigarettes paired with electric shocks; the electric shocks reflexively cause pain (UCR)• After several pairings, even the sight or smell of cigarettes (CS) leads to a negative emotional response (CR) i.e. an aversion
  • 4. Solution – to example Baseline NS: Cigarettes evokes stage No aversive response UCS: Electric Shocks evokes UCR: Pain & anxietyAcquisition Repeated pairings of stage NS (Cigarettes) & UCS (electric shocks) evoking UCR (pain & anxiety) Post CS: Thought of Cigarettes evokes
  • 5. Aversion therapy• E.g # 2. Internet addiction• Required: Describe the process in terms of the 3 stages of Classical Conditioning
  • 6. Solution – to examples # 2 Baseline stageAcquisition stage PostConditioning
  • 7. Solution – to example # 2 Baseline NS: Playing on the Internet evokes stage No aversive response UCS: Electric Shocks evokes UCR: Pain & anxietyAcquisition Repeated pairings of stage NS (Internet activity) & UCS (electric shocks) evoking UCR (pain & anxiety) Post CS: Thought of internet evokes
  • 8. Limitations of aversion therapy• Ethical considerations i.e. causing physical or psychological pain to patient• Overgeneralisation i.e. avoiding drinking of all types of liquid rather than merely alcohol• Extinction often occurs without repeated administrations of UCS & CS pairing i.e. the• Aversion might not materialise unless they know UCS (nausea inducing drug) will coincide with alcohol consumption
