Good question Painter, I might have to run a test on my pupils as well, see if they score their age (16-18), and perhaps draw some conclusions from that.
But from the test it seems like at least the japs think a younger brain is better. Hmm, wonder what age a perfect score would give?
My 1st attempt I scored a lowly 37!
2nd attempt…38!!
3rd attempt…39!!!
4th attempt abandoned as test was getting closer to the truth.
5th attempt…32!!..LOL…all i done was go to watch the football match on TV (BTW Im 45 in 2 weeks…sounds familiar? )
I think this test is associated with the therories surrounding the left and right hemispheres of the brain. The left hemisphere is where we take information in, the right hemisphere is where our brain attempts to process and analyse that information very closely, often referred to as advanced thinking in the right hemisphere and raw data input in the left hemisphere. Crucially between the two hemispheres there is a filter down on the underside of the brain, that filter controls the amount of raw information that gets through for analysis.
The older we get the more the right hemisphere takes over and filters out a lot of information that we see. Everyone actually has a photographic memory because your left hemisphere takes in absolutely everything, but there is an area of our brain that filters out what we need and the right hemisphere goes into detail analysis of what gets through the filter. A good example of this is when you find yourself working away and something distracts you that causes you to put something down, when you try to find it again you think you put it somewhere but when you look its not there, so you look everywhere else. But when you scan over the place that you actually put it you fail to see it, this is because your right hemisphere has already told you that it is not there (where you are looking because you thought it was somewhere else) so it over-rules the left hemisphere that sees it clearly as it is there. If however you ask someone else if they have seen it they have no pre-conceptions of where it is or it isn’t so they see it immediately and inform you that its under your nose you idiot Another good example is the theory of spelling and reading. Someone posted an article a while back explaining how the mind worked and demonstrated that we do not actually read every letter but the advanced thinking takes over and so long as the first and last letter are in the right place and roughly the correct letters form the body of the word then we can read it quite happily.
Very interesting the left/right hemisphere brain subject, IIRC it really affects some people who have a disorder in the filter department as their brains are bombarded with far too much information constantly and they end up going crazy.
I guess this test is testing the left/right because on my best run at the test when I got upto the region of 9 digits at a time you cannot possibly look at and process all 9 digits in such short time but crucially you do see them so the information is lodged in the left hemisphere, when I then ‘pointed’ to give my answer I was not sure where they were but was running on instinct which just happened to be spot on several times and did not let me down. So by trusting my instincts I was not actually processing what I saw, in fact I was only looking in the middle of the screen and relying on the left hemisphere to soak up the information required, that would account for the error that I made which was to mistake a 6 for an 8 or 9, all pretty similiar if not looked at directly.
Read a huge article sometime ago about the left/right brain subject and it was hugely interesting, watched a couple of documentaries as well and I did find it a very involving subject.
edit: I guess 20 is determined as optimum brain age where we see and process someones idea behind of the perfect amount of information

Spot on. I think I, on an unconsious level, tried to sort the numbers already while I was seeing them, and that worked pretty good when it was only 3 numbers (or perhaps 4), but with more then that it’s simply isn’t possible with the limited time. On my second run I concentrated more on simply trying to register the numbers and do the sorting later on, which obviously worked better. (And perhaps my brain had awakened a bit more.:o ) Next up is simply going on pure instinct (but not now, 9+ hours at work is not a good preparation I think).
