Attentional Blink Test
A square shows a quick stream of colours, one after another. Somewhere in the stream is red, once. Afterwards, pick the colour that came right after red from five: green, blue, yellow, magenta or white.
The stream speeds up when you are right and slows down when you are wrong, homing in on how long each colour must be shown for you to be right 80% of the time. Guess when you are not sure; a guess is right 1 time in 5. Usually 40 to 50 streams, about four minutes.
Right after the eye catches one target, the next thing is often missed: the attentional blink. How quickly a person recovers is a measure of the speed of attention. Use a quiet moment and keep your eyes on the square.
Almost done!
Two optional questions, asked once: your age and sex let the results be broken down by who took the test.
Sex as at birth; gender as you identify. Languages you grew up speaking; several are fine, separated by commas. Leave blank anything you would rather not say.
