Stroop Test

Choose the ink color, not the word, across 30 rounds. See your score, accuracy, and response-time difference.

How to Play

  1. Pick the INK COLOR of the word — not what the word says.
  2. 30 trials. Be as fast and accurate as you can.
  3. We measure your 'Stroop interference' — the slowdown on mismatched trials.

This is a color-choice game. The result is your record in this game; it does not diagnose attention or cognitive ability or compare you with other players.
