Module description
A diverse range of psychological theories have been proposed to explain addictive behaviour. Whereas clinical psychologists highlight the importance of psychiatric comorbidity, developmental psychologists focus on early risk factors in childhood and adolescence, human cognitive psychologists advocate biases in selective processing, behavioural economists favour notions of rational choice and reward value, neuropharmacologists focus on cognitive impairment, hypofrontality and compulsivity, and animal learning theorists emphasise the role of Pavlovian and instrumental learning. Each theoretical model of addiction has unique implications for the best intervention strategy that should be adopted to reduce drug use. Moreover, the optimal intervention strategy depends on the specific population under consideration. It is likely that different intervention approaches should be developed for diverse groups such as pregnant smokers, middle class alcoholics, heroin addicted prisoners/homeless, high risk adolescents, etc. Each session will deal with a single issue in addictive behaviour. We will start by considering the core theoretical mechanisms that are thought to drive addiction, and then cover some of the key intervention strategies that have been evaluated to reduce/prevent drug use. In the end, you should have a firm idea of the potential causes of addiction, and what the best strategies are to intervene.
Module aims - intentions of the module
The objective of the module is for you to arrive at an understanding of what causes addiction, and what the best approach is to counteract it, from amongst the multitude of possibilities. There is sufficient flexibility built into the module such that you can select the material that you wish to focus on to develop your favoured specialisation, for example, clinical, educational, legal, experimental etc. The module covers basic science and clinical science in roughly equal proportion. The module convenor’s research programme focuses on individual differences in vulnerability to dependence, and this topic is covered in some detail the module.

Re-assessment notes
Three assessments are required for this module. Where you have been referred/deferred in the examination you will have the opportunity to take a second examination in the August/September re-assessment period. For a deferred presentation, reassessment will be by arrangement with the module convenor. For a referred presentation, reassessment shall be by individual presentation in the August Ref/Def period. Where you have been referred/deferred in the coursework you will be required to resubmit the coursework. If you are successful on referral, your overall module mark will be capped at 40%; deferred marks are not capped.
