Dynamic social systems and adolescent alcohol/tobacco use: A new cusp catastrophe model. This research will substantially improve our understanding of the development of adolescent high-risk behaviours. It will directly inform multimodal prevention strategies by demonstrating how substance use, peer factors, and parent relationships unfold over time. This is much needed because most prevention strategies are too simplistic to address complex precursors to alcohol/tobacco use. The research wil ....Dynamic social systems and adolescent alcohol/tobacco use: A new cusp catastrophe model. This research will substantially improve our understanding of the development of adolescent high-risk behaviours. It will directly inform multimodal prevention strategies by demonstrating how substance use, peer factors, and parent relationships unfold over time. This is much needed because most prevention strategies are too simplistic to address complex precursors to alcohol/tobacco use. The research will benefit health researchers in and beyond Australia who seek to understand behaviours that do not adhere to conventional assumptions. Collaboration with researchers from leading national and international centres will enhance Australia's research reputation and will attract postgraduates and researchers to Australia.Read moreRead less
Distinguishing categories and dimensions: Taxometric investigations. This project aims to apply and refine promising new methods for classifying psychological variations. These "taxometric" methods detect categories and locate their boundaries, enabling improved taxonomies of personality and mental disorder. They will be used to examine whether personality disorders are discrete categories or fall on a continuum with normal personality, and whether people mentally represent social groups accordi ....Distinguishing categories and dimensions: Taxometric investigations. This project aims to apply and refine promising new methods for classifying psychological variations. These "taxometric" methods detect categories and locate their boundaries, enabling improved taxonomies of personality and mental disorder. They will be used to examine whether personality disorders are discrete categories or fall on a continuum with normal personality, and whether people mentally represent social groups according to qualitatively distinct ontological assumptions. The statistical validity of these methods will be comprehensively assessed. The project should help to resolve enduring questions about psychological classification and deepen our understanding of social stereotyping.Read moreRead less
