Decision science

Decision Science Perspectives on Addiction. Drug use and other addictive behaviors involve making choices whether they or conscious or not. Smoking for instance involves making choices between the reward a smoker experiences by smoking balanced against the negative immediate (e.g. cost) and long term (e.g. cancer) negative consequences of smoking. CfAST investigators have used a number of approaches for investigating decision making in the context of addiction. Neuroimaging studies have been conducted to evaluate brain regions involved in valuation of drug and nondrug reward and the influence of nicotine on brain reward networks. Other studies have investigated explore vs. exploit tradeoffs as a novel framework for understanding tobacco use and other addictive behaviors (e.g. gambling).
