The Stroop Effect

The Stroop Effect is a wonderful example of how our two cognitive Systems come into conflict. Take the following stimulus card:

To experience the Stroop Effect read from left to right calling out the color of the ink for the first two rows. You'll note how easy that was. But now try to call out the color of the ink for the remaining words. Try to go as fast as you can. When you do this you'll feel the difference. You'll go slower and probably make a mistake or two. That slowing down and increase in error rate is called the Stroop Effect.
