Tetris as a trauma reducer?

UK researchers say the video game Tetris may work to reduce Post Traumatic Stress Disorder, BBC news reports:

The Oxford University experiment works on the principle that it may be possible to modify the way in which the brain forms memories in the hours after an event.

A total of 40 healthy volunteers were enrolled, and shown a film which included traumatic images of injuries.

Half of the group were then given the game to play while the other half did nothing.

The number of “flashbacks” experienced by each group was then reported and recorded over the next week, and those who played Tetris had significantly fewer.

The study was recently published in the online, open access journal PLoS One.
