The process of understanding Posttraumatic Stress Disorder (PTSD) has been a long and difficult one. It is safe to say our understanding of this disorder in incomplete, and our exploration into its pathophysiology is fairly recent. As with any disorder of the brain, the complexities of PTSD are extensive and require integrating cognitive, functional, and chemical components. Given this complexity, it is no wonder that treating PTSD has also been a challenge. Treating a disorder whose components are not fully understood is similar to shooting in the dark. Some shots have hit their mark and some have missed. More than ten years after its conception, the question of whether Eye Movement Desensitization and Reprocessing (EMDR) is a hit or a miss is still debated. If understanding the pathophysiology of PTSD is still recent, understanding the possible physiology behind EMDR is just beginning. This paper will define PTSD, explain some aspects of its physiology, and present some hypotheses as to why EMDR may be a successful treatment for PTSD.
Eye Movement Desensitization and Reprocessing (EMDR) is an integrative psychotherapy approach that has been consistently evaluated as efficacious in the treatment of posttraumatic stress disorder (PTSD). The information processing model that guides its clinical application posits that EMDR should be effective in treating other psychological disorders that have experiential contributors. Research is needed to assess such applications. This special issue features three case series in which EMDR was applied to the treatment of complex PTSD, phobias, and chronic pain, respectively. The authors discuss deficits in the research literature, provide preliminary data on EMDR treatment of these conditions, and offer descriptive guidelines for evaluation that are achievable by the practicing clinician. Two additional articles offer preliminary data on physiological and cognitive/affective concomitants of therapeutic change. It is argued that clinicians should play a greater role in the rigorous and extensive examination of psychological treatments in the context of the exigencies of clinical practice.
The fear of speaking is often cited as the world's most common social phobia. The rapid growth of computer technology enabled us to use virtual reality (VR) for the treatment of the fear of public speaking. There have been two techniques used to construct a virtual environment for the treatment of the fear of public speaking: model-based and movie-based. Virtual audiences and virtual environments made by model-based technique are unrealistic and unnatural. The movie-based technique has a disadvantage in that each virtual audience cannot be controlled respectively, because all virtual audiences are included in one moving picture file. To address this disadvantage, this paper presents a virtual environment made by using image-based rendering (IBR) and chroma keying simultaneously. IBR enables us to make the virtual environment realistic because the images are stitched panoramically with the photos taken from a digital camera. And the use of chroma keying allows a virtual audience to be controlled individually. In addition, a real-time capture technique was applied in constructing the virtual environment to give the subjects more interaction, in that they can talk with a therapist or another subject.
