The aim of this thesis was to examine the impact of an identity delusion on autobiographical memory and develop a model of deluded autobiographical memory to guide future research in this area. Given the difficulty of studying identity delusions in isolation from other clinical disorders, this thesis presents six experiments that used hypnosis as a laboratory model of identity delusions. Chapter 1 reviews literature from three distinct areas, including delusions, autobiographical memory, and hypnosis. Chapter 1 reviews a model of the self and autobiographical memory proposed by Conway (2005) and outlines the value of using hypnosis instrumentally to model delusions of self. Chapter 2 presents two experiments that established hypnosis as a suitable paradigm for investigating identity delusions. These experiments examined the parameters of the hypnotic delusion and tested the impact of the delusion on self and autobiographical memory. Chapter 3 presents two experiments that continued to examine the characteristics of autobiographical memory during a hypnotic identity delusion. These experiments indexed the specificity, source, perspective, and qualitative features of autobiographical memories elicited during a suggested identity delusion. Chapter 4 presents two experiments that investigated memory processing during a hypnotic identity delusion. These experiments illustrated the shifting accessibility of autobiographical memories during a hypnotic identity delusion. Finally, Chapter 5 draws the empirical findings together to discuss the value of hypnosis as a technique for modelling identity delusions and the ways in which a hypnotic identity delusion influences autobiographical memory. Importantly, Chapter 5 proposes a model of deluded autobiographical memory that integrates Conway???s (2005) self-memory system with relevant aspects of Langdon and Coltheart???s (2000) two-factor theory of delusions. Using this proposed model as a framework, Chapter 5 discusses the clinical and theoretical implications of the findings from this thesis and suggests future research directions.
