Childhood neurodevelopmental factors and risk of psychotic experiences in early adolescence: genotypic variation and developmental endophenotypes

This thesis was about understanding the childhood developmental factors that may lead to psychotic experiences in early adolescence. It also contributed to efforts towards preventative strategies for children with a high risk of psychotic symptoms, and arguably schizophrenia. Based on the findings, the author concluded, that further research on this topic should focus on the development of early detection methods and interventions for high risk children.

Violent offending, masculinity and age: exploring the role of developmental processes in adulthood

While the link between violent crime and masculinity is often implicitly assumed, to date, research has not specifically investigated beliefs about violence and masculinity at different stages of the adult life-course. This thesis explored the role of maturational processes in the way beliefs about masculinity and violence may differ in early and middle adulthood. Results of a quantitative study did not uncover statistically significant differences between younger and older adult violent offenders on a measure of criminal thinking. However, results of an interpretative phenomenological analysis indicated that beliefs about masculinity may differentially influence violent crime at different stages of adulthood. The results of these two studies provide a foundation for arguing that beliefs about violence and masculinity change throughout the life-course, and that masculinity in particular may be important treatment target in contemporary rehabilitation programs.
