  5. Aversion Therapy • Aversion therapy can be used with alcoholics. • Alcohol is paired with an emetic drug (a drug which causes nausea and vomiting). • Over time the alcoholic associates alcohol with being sick and does not want to drink alcohol anymore. • Other drinks such as soft drinks are given without the drug so that the person is not conditioned to feel sick to all drinks.

  6. Aversion Therapy • Aversion therapy can be used with paedophiles. • Paedophiles can give themselves a self-administered electric shock every time they look at a child or a picture of a child.

  7. Research Evidence for Aversion Therapy • Meyer & Chessel (1970) Found that 50% of patients who experienced this treatment abstained from alcohol for a year. (Better than the no-treatment group).
