Neurobiology of Dissociation

Clinical Psychology, Psychometrics and Statistics

In the last years, there has been an ongoing debate about the role dissociation plays in health and disease, based on its putative role elucidating the emergence of consciousness. Currently, the construct of dissociation is neither well defined nor readily objectified. Within my research agenda, pathological dissociation will be conceptualized as a form of reactive, uncontrollable emotion regulation resulting in depersonalization, derealization, and emotional numbing, but not identity fragmentation or memory departmentalization. Over the course of the next five years, my group will explore the role of pathological dissociation in the development, maintenance, and treatment of trauma-related disorders. Using varied methodological approaches (including ecological momentary assessment, behavioural experiments, psychophysiology, and neuroimaging) we will test the hypotheses that pathological dissociation (1) can be objectified using psychophysiological measures, (2) results from altered prefrontal functioning, (3) is directly related to the development of intrusions, and (4) correlates with behavioural alterations such as attentional bias and risk for re-victimization.
