In this lecture, professor Gwen Adshead explores violence, offenders and the criminal personality through the perspective of psychology and psychiatry, and how the study of psychology and psychiatry relates to the study of criminology. Historically criminals have been defined as a group who are seen as “other” to non-criminals. However, modern thinking has moved away from this with developments in the psychology of criminal rule-breaking and discussions of how individual psychology can assist the understanding of criminal rule-breaking and risk; including approaches to rehabilitation and behavioural change. Professor Adshead suggests that these different discourses have much to offer one another.
