You read the word. You need the colour.
Try the 16 trials. Half have a matching word and ink colour; in the other half they conflict. At the end, compare the times of your correct responses.
This is a short illustration of Stroop interference. The experiment published in 1935 used a different protocol. A phone run does not show how good your attention is overall.
What you see also depends on the surroundings.
Compare the centre circles, then choose an answer. You will see the same two diameters with the surrounds faded.
The Ebbinghaus illustration shows how context can change perceived size. The strength of the effect differs across arrangements and people; you may see the circles as equal from the start.
Do you remember it, or does it feel familiar?
Read the list, hide it and answer the question. There is no timer: take as long as you need.
Related words can make an absent word feel familiar. This eight-word illustration is shortened from the Deese–Roediger–McDermott paradigm; it does not reproduce the published experiment or assess your memory.
