What makes some people develop an addiction while others don't? Could genes or social environment influence addictive behaviours? In this album, scientists in the US and the UK explore the psychology and biology of addiction by subjecting a recovering alcoholic and his sister, a non-addict, to a range of physiological, psychological and genetic studies. The results raise interesting questions about brain patterns underlying addictions, and how addiction should be treated. This material forms part of The Open University course SD805 Issues in brain and behaviour.
