However, they discovered the three young chimps could remember many numerals with a glance, with virtually no change in performance even when the numbers were flashed for just 210 milliseconds
I think it would be a lot more difficult if the numbers actually moved. Our brains are very spatially oriented, making remembering positions or lines (as sillysaurus3 pointed out) much easier.
Would help out myself, but I'm on vacation and it's late here.

Y'all need to help me with the next levels I have planned: The numbers will only appear for a limited time...
