After the positive cognition has been strengthened and installed, the therapist will ask the person to bring the original target event to mind and see if he notices any residual tension in his body. If so, these physical sensations are then targeted for reprocessing. Evaluations of thousands of EMDR treatment sessions indicate that there is a physical response to unresolved thoughts. This finding has been supported by independent studies of memory indicating that when a person is negatively affected by trauma, information about the traumatic event is stored in motoric (or body systems) memory, rather than narrative memory, and retains the negative emotions and physical sensations of the original event. When that information is processed, however, it can then move to narrative (or verbalizable) memory and the body sensations and negative feelings associated with it disappear. Therefore, an EMDR therapy session is not considered successful until the client can bring up the original target without feeling any body tension. Positive self-beliefs are important, but they have to be believed on more than just an intellectual level.
