The Attention Span Test

Instructions

For the first test we use rows of random numbers. You select the size of the row, click the button to get the row, take a quick look at it, close your eyes and visualize the numbers.

Now this is very important, you have to see every letter clearly and distinctly AND all the letters clearly and distinctly, AT THE SAME TIME.

Don't use any memory tricks or other tricks in order to increase the amount of numbers such as chunking them together. This is not a memory test.

Continue to increase the size of the row until you reach your limit. It could be three numbers or five numbers, or more. As soon as you come to the point where you can't see every number clearly and distinctly, where some numbers become blurred, or you have to jump quickly from one end of the row to the other, you have reached the size of your your attention span.
