The Oxford team showed a film to 40 healthy volunteers that included traumatic images of injury from several sources, including advertisements on the dangers of drunk driving.

After waiting 30 minutes, half the people played Tetris for 10 minutes while the others did nothing. Those who played the game had far fewer flashbacks to the film over the next week.

DragonOfPain,, please understand that my reply is not directed at you.
There are so many of these tiny experiments and they are reported as if it is a major breakthrough...

Sorry, but to me that is a crock...
40 healthy volunteers does not equal those who have lived the traumas.
40? and healthy?
Has a lot in common with people with PTSD?
BS

Google PTSD and you will find 54,098 similar experiments with very little in common with controlled studies
Arrgghh, these things PO me

Thank you for sharing because it may be of help when we do need a distraction and play a game.
