With the help of Rick Mahurin of the Battelle Seattle Research Center, NOVA has made available a Shockwave demonstration of the Stroop Test. In the demonstration you will be presented with three levels of the test. Quickly choose the word that matches the color within the rectangle on top. Quickly choose the word that matches the word on top. Quickly choose the color in which the word on top is written, rather than the color that the word names.
Most people find the last level the hardest.
You probably will take more time for each word, and may frequently make the mistake of saying the word itself, rather than naming the color in which the word appears. For instructions on downloading the Shockwave plug-in, take a look at the NOVA Online Technical Help .
