The Stroop effect is named is by John Ridley Stroop, who first published the effect 1935, the stroop effect is a phenomenon in which you must say the color of a word but not the name of the word. Blue for example might be printed in red and you must say the color rather than the word. While it might sound simple, the effect refers to the delayed reactions times when the color of the word does not match the name of the word..

Make a test yourself with this fun game and try to deny this theory. ;)

Do not get distracted, focus on the color you read!!
