Tetris Inoculation Against PTSD

Here's an interesting article on PsychCentral.com about PTSD. Following is the theory behind the research. Read the full article for more information:

Our theory is based on two key findings:

1) Cognitive science suggests that the brain has selective resources with limited capacity;

2) The neurobiology of memory suggests a 6-hr window to disrupt memory consolidation.

The rationale for a ‘cognitive vaccine’ approach is as follows: Trauma flashbacks are sensory-perceptual, visuo-spatial mental images. Visuo-spatial cognitive tasks selectively compete for resources required to generate mental images. Thus, a visuo-spatial computer game (e.g. “Tetris”) will interfere with flashbacks.
