RecruitingDevice studyMechanistic Interventions and Neuroscience of DissociationThe purpose of this study is to test the neurophysiological mechanisms of an intervention to reduce symptoms of dissociation in traumatized people. The intervention will be tested in dissociative traumatized people at two sites: Emory University and University of Pittsburgh. The researchers are interested in whether neural networks associated with attentional control and interoceptive awareness can be enhanced in this population. The researchers propose to evaluate whether different body-focused and non-body focused interventions can change these mechanisms.
