 3. Facial Behaviour - A laptop camera, located three feet away from the patient, will record the patients face throughout the entire 2 treatment sessions, so that the time when the different phases of EMDR are administered can be matched to the same time on the patients arousal level response. In order to accurately match patients arousal responses to what treatment phase of EMDR was being administered recording must be achieved. Recording facial behaviour may also allow for other observable analysis to be completed.
