'Virtual Iraq' Simulation To Study Post-Traumatic Stress Disorder

'Virtual Iraq' Simulation To Study Post-Traumatic Stress Disorder: "Weill Cornell Medical College researchers are using a virtual reality simulation called 'Virtual Iraq' to better understand how symptoms of post-traumatic stress disorder (PTSD) develop. In their ongoing research trial, participating Iraq War and Gulf War veterans with and without PTSD are shown a brief, 3-D virtual-reality simulation of an urban combat scenario. They wear a headset, through which they hear, see, and — using a keypad — 'move' through a 'virtual world' in which images change in a natural way along with head and body movement."
