Forty volunteers were used in the experiment. They were enlisted and shown a film which included traumatic images of injuries.
The study worked on the principle that it may be possible to modify the way in which the brain forms memories in the hours after an event.
After viewing the distressing images, some were given Tetris to play 30 minute later. The others were given nothing.
BBC Online report that the scientists said that perhaps the players had fewer "flashbacks", because it helped disrupt the laying down of memories.
PTSD can affect anyone who has suffered an unexpected and shocking incident. One of the main features of it is the “flashback,” when the distressing sights, sounds or smells return.
Tetris was observed to reduce the flashbacks in those who played it. The game may be working, according to the research, by competing for the brain’s resources.
