In essence, aspects of psychobiological functioning that should be associated, coordinated, and/or linked are not… Dissociative symptoms are characterized by (a) unbidden and unpleasant intrusions into awareness and behavior, with accompanying losses of continuity in subjective experience: (i.e., ‘positive’ dissociative symptoms); and/or (b) an inability to access information or to control mental functions that normally are readily amenable to access or control: (i.e., ‘negative’ dissociative symptoms’)”.
