Say I tell you to press a key every time the letter A appears.
The latest says that it takes only 13 milliseconds
Others say it is 80 milliseconds
milliseconds for the brain to fully understand what it is looking at?
In Flash Anzan, 15 numbers are flashed consecutively on a giant screen. Each number is between 100 and 999. The challenge is to add them up.Simple, right? Except the numbers are flashed so fast you can barely read them.I was at this year's championship to see Takeo Sasano, a school clerk in his 30s, break his own world record: he got the correct answer when the numbers were flashed in 1.70 seconds.
So assuming there is a gap of perhaps 10 ms between numbers, he was reading and processing a 3 digit number, storing the result, clearing his memory, and reloading the running total, in 100 ms. Or just remembering a sequence of random numbers and adding them up later.
