Play Stroop Effect Test Online Free - Brain Color Word Game
What is the Stroop Effect?
The Stroop Effect is a famous psychological phenomenon first described by John Ridley Stroop in 1935. It demonstrates how the brain processes conflicting information: when a word (e.g., RED) is printed in a different color (e.g., blue ink), your brain slows down trying to reconcile the two conflicting signals. This free online test lets you experience and measure this effect yourself.
