When I'd finished writing the previous post yesterday, I did a spot of Dr. Kawashima's Brain Training on my Nintendo DS Lite - got to keep Edublogger off my back! I have found that it's usually better to do this stuff in the morning; presumably that's why in primary school we spent the morning doing sums (always beginning with "mental") and spelling and left the afternoon for the quieter occupations of essay-writing and sewing. (Now there's a thing. As an English specialist I would now have to object to that, in the same way as I used to ban my Higher pupils from discussing maths in my room). However, the morning was long gone and I hadn't done my daily training. It was time to get on with it.
I discovered two interesting things. The first was actually slightly scarey: I found that when I had completed 100 sums - the "difficult" mode, including subtraction and division as well as the usual addition and subtraction - the front of my head felt .... warm. Warm in the way my ear does when I've been using my mobile phone. According to Dr K, "Quickly solving equations makes the prefrontal cortex quite active", and here I was feeling I had a hot head. Question: is your prefrontal cortex situated between your eyebrows?
And then I made the second discovery - because I went on to do the Brain Age check. For this, you have to do three randomly-selected tests (so they're not always the same): a Stroop test, plus a word memory test and a number-recoginition test were the ones last night. And my brain age had gone down to 33! Hurrah! I hadn't done the test for a week because I was unwilling to have it go back up from the 44 I'd reached - but the proof is above for all to see so I'll risk it again next week. In defence of my sparring partner who appears to be 80, I have to say that he's in the throes of composition at the moment with a deadline to meet - a sort of musical "Ready Steady Cook" - so sums and words aren't really on the agenda.
And my last discovery since last post came thanks to Bishop Martin, who keeps denying any tincture of geekery. I learned how to insert colour into my text. I've only been at it for a year - how sad is that?
