I have done the picture recognition test with my audiences. The test where they see a number of pictures for anywhere from 1 to 0.1 seconds each and then have to pick the pictures they have seen from a few that appear on the screen at a time.
First attempt is 50 pictures for one second each and then two options to pick, A or B.
The second is 100 images for 3/4th of a second each and then four options, A to D.
Both times as good as everyone (few exceptions) manage to answer at least 80% correct. The first one sees almost everyone get above 90% even.
But that is pictures. Has anyone here ever tried this test with something like words or numbers?
Or have you demonstrated the power of recognition in another way?
