Something very cool is happening with my brain.
I’ve been doing some Dual N-Back training – where you watch and listen to a series of shapes and sounds appearing in sequence on a 3×3 grid, and then you try to identify which ones appeared 1 or 2 or 3 times back. I downloaded the free program from http://brainworkshop.sourceforge.net and I’ve been practicing about 20 minutes a day.
I started out just barely able to do the 1-back (where you have to identify the location and sounds of what just appeared before), then I progressed to the 2-back, where you skip one and then try to remember what came the time-before-last.
Google “dual n-back training” for a better explanation.
Anyway, to make it quick (because supper is on the stove and the timer is beeping), today I got back wrong change from a cashier, and I actually remembered what bill I had given her – a $10, not the $5 she gave me change for.
Holy crap. I haven’t remembered that sort of thing in a long, long time. I am usually bumfuzzled and unsure and slow to react, so I don’t even ask. Heaven only knows how much money I’ve lost over the years, because of just not being fast enough to speak up.
Onward with the dual n-back training!
