How to Play: The Stroop Test

This is a classic measure of cognitive control and processing speed. Your brain will try to trick you; you must use focused attention to win!

  1. The Task: A word (like "BLUE") will appear in the center of the screen, printed in a specific color (like RED ink).
  2. The Rule: You must click the button that matches the INK COLOR of the word, completely ignoring what the word actually says.
  3. Start: Press "Start Test" to begin the sequence of 30 rapid trials.
  4. Scoring: The system tracks your accuracy and the total time it takes you to complete the 30 trials. Higher accuracy and faster time yield a better score.
If the word is BLUE but the ink is GREEN, you must click the GREEN button.

💡 The Challenge: Your brain automatically processes the word, creating interference that slows your response. The faster you overcome this, the higher your score!
