Stroop Effect

The Stroop effect is a classic demonstration of cognitive interference. It shows how our brains automatically and effortlessly read words, even when we are asked to focus on a different task—like identifying the color of the ink. This test measures your ability to override that automatic process and focus on the task at hand.
