Tetris for Trauma Victims? – Implications for Multitasking
// March 29th, 2010 // Comments Off // Information Overload
Friday’s Telegraph had a really interesting piece on some research by a team at Oxford University – the original research paper is well worth a read.
The team took 40 guinea pigs and subjected them to a harrowing 12-minute video of death and injury – this is apparently a standard analog for post-traumatic stress disorder. After a 30 minute break, half sat quietly while the other half…. …played Tetris. All kept a diary for a week and the Tetris players had significantly fewer flashbacks than the control group.
Why? Because the brain has only “limited visuospatial working memory resources” to consolidate experiences as memories and Tetris is, apparently, a great way of soaking up those resources at the expense of other – in this case harmful – cognitive activities. So, as an alternative to drugs or cognitive behaviour therapy, this is being viewed as a potential treatment for PTSD sufferers.
But turn the idea on its head for a minute. What intrigues me about this is the brain’s powerful ability to constrain its own activity if multiple demands are made on its resources. For me it’s another powerful argument against attempting to multitask.
