Tetris — is there anything it can’t do? Now it appears that the computer puzzle may ease post-traumatic stress:
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.
