1. Introduction* Criminology and serotonin* The importance of studying the link between violence and serotonin* Outline what will be written in each chapter2. Methodology* Literature review – definition of lit review and explain why it is the most appropriate source* Explain why I haven’t used primary research eg – ethical issues etc* Benefits of lit review as opposed to primary research in general. Also, specifically in terms of serotonin levels and violence* Pros/cons of secondary data sources (emphasis on pros)3. Definitions* Define violence including: trends in violence, legal definitions, Bartol and Bartol (2005) – all violence is aggressive but not all aggression is violent* How has violence historically been understood?* How has violence historically been explained?4. The relationship between serotonin and violence* How can serotonin explain violence?* A history of how serotonin has been understood* The historical link between serotonin and violence5. The link to mental health* Mental health and serotonin levels – depression* Evidence including positive correlations* Can serotonin levels affect mentality and whether a person is more prone to commit violent acts?* Include evidence – case studies, medical support, correlations, court cases where individuals have used mental health as a defence for violent acts (especially those with levels of high/low levels of serotonin)If possible, I could do with a summary ASAP so I can do a presentation on the content of the dissertation.
