The Stroop effect is the finding that naming the colors of color words (e.g. the words 'green', 'red', 'blue', etc.) is easier and quicker if the actual observed colors of the words match the colors that the words denote (e.g. the colors green, red, blue, etc., respectively) than if they do not match.
