Psychologists are experimenting with virtual reality-based therapy to treat U.S. soldiers returning from Iraq who show signs of post-traumatic stress disorder (PTSD).
Clinicians, currently conducting research at military medical centers in Washington, California, Hawaii, and Georgia, can also incorporate a number of smells -- body odor, gunpowder, or burning rubber -- to enhance the therapy sessions.
"What this technology does is give us an environment to help facilitate soldiers' telling of their own story."
