Tetris reduces visual flashbacks of gruesome scenes

I know that watching gruesome movies hasn't got anything to do with baking gluten free food.  However, as Tolerant Taster does heroically try biscuits, cakes, pies and other baked goods, sometimes several in a day and always with patience and precise commentary, it doesn't seem unreasonable that I should accompany him to the movies he sees for his Film Group.  As a result of that I have seen more miserable or  unpleasant movies in the last couple of months than I would normally see in a decade.  I did walk out of a couple.  At home I switch the TV off or, if unable to do that, put my fingers in my ears and close my eyes at unpleasant moments.

A study found that if you do a visually challenging task soon after seeing unpleasant images it seems to disrupt the laying down of the visual memories that are the basis of flashbacks.  The original article is available at

So, next time, I should watch the whole movie but come home and play a computer game before I go to bed.  I haven't played Tetris since it was the one thing the BBC computer would do, back in the day when a file couldn't be more than four pages long, which made writing my first Masters thesis hard, floppy discs really were floppy, colour printing hadn't been invented, and printer paper came with perforated edges for the sprockets.

I don't know if this can be extended, but if I should happen to make a particularly unpleasant food and compel TT to try it, I should follow this up with something delicious soon after.  Not only would that cleanse any residual flavour and texture from the palate but it would disrupt the taste memory being established that could in the long term develop into a generalised fearfulness when new foods approach.
