Binary numbers are used in computer language, and they are exclusively
made up of ones and zeros. They will appear on the screen in threes, and
then disappear after being exposed for the time determined by the test,
either 1 or 4 seconds. When they disappear, the participant will have to
write them down on a piece of paper in the correct order.

digits like this:

101 001
010 111
