| Abstract | Psychopathy is a personality disorder comprised of a constellation of traits, such as lack of remorse, lack of empathy, impulsivity, and irresponsibility. Although much research has been conducted on this personality disorder, the neural correlates remain poorly understood. Progress in this realm has been hindered by two factors. First, given the large body of work supporting delineation of psychopathy into subtypes (based on trait anxiety), the exploration of dissociable neural correlates between subtypes has been insufficiently studied. Second, many studies utilize a single neuroimaging modality to explore a given neural property, and thus, cannot answer comprehensive questions about neural network dynamics. The current work addresses both limitations in the literature by examining, in a community sample, the relationships between psychopathic traits, trait anxiety, and neural properties (function, functional connectivity, microstructural integrity) using multiple neuroimaging methods. The two overarching aims of this dissertation are to determine whether the relationship between psychopathic traits and neural properties is dependent upon trait anxiety, and whether these relationships are evident across several different neuroimaging modalities. |
