Stroop Effect

Colors, Colors

The famous "Stroop Effect" is named after J. Ridley Stroop who discovered this strange phenomenon in the 1930s. Here is your job: name the colors of the following words. Do NOT read the words...rather, say the color of the words. For example, if the word "BLUE" is printed in a red color, you should say "RED". Say the colors as fast as you can. It is not as easy as you might think!

Try this Interactive Stroop Effect Experiment. The computer will keep track of the time it takes you to say the colors of the words.

StroopEffect Experiment

In this experiment you are required to say the color of the word, not what the word says. For example, for the word, RED, you should say "Blue."

As soon as the words appear on your screen, read the list as fast as you can. When you have finished, click on the "Finish" button. The time it took you to read all of the words will be shown. If you want to try the same set of words, click on the "reload" button of your browser. If you want to continue with the experiment, click on "Continue Experiment."
