Tetris: an excellent treatment for post-traumatic stress disorder?

Tetris is good for easing the effects of post-traumatic stress disorder (PTSD), scientists have found. Yes, you read that correctly: the infuriating, mind-swallowing piece-twiddling row-building game actually has a medical value.The research, which was conducted at the department of psychiatry at the University of Oxford, suggests using Tetris as a "cognitive vaccine" against flashbacks from traumatic events. It's published on the open-source science research Public Library of Science (PLoS) website.Here's how they set out their recommendations: The rationale for a 'cognitive vaccine' approach is as follows: Trauma flashbacks are sensory-perceptual, visuospatial mental images. Visuospatial cognitive tasks selectively compete for resources required to generate mental images. Thus, a visuospatial computer game (e.g. "Tetris") will interfere with flashbacks. Visuospatial tasks post-trauma, performed within the time window for memory consolidation, will reduce subsequent flashbacks. We predicted that playing "Tetris" half an hour after viewing trauma would reduce flashback frequency over 1-week.In other words,...
