Stroop Test

Match if word = color No Match if different

How the Stroop Test Works

The Stroop Effect is a classic psychology experiment demonstrating cognitive interference, which happens when your brain processes conflicting information.

  1. A color word appears (like "RED" or "BLUE")
  2. The word is displayed in a color that may or may not match
  3. Press Match if the word matches its color
  4. Press No Match if they're different

Why Is This Hard?

Your brain reads the word automatically, but must override that to identify the color. This requires cognitive control: the ability to suppress automatic responses.

Fun Fact: Named after John Ridley Stroop who published this effect in 1935, the Stroop Test is still used today to assess attention, processing speed, and cognitive flexibility.

How to play

A color word like RED or BLUE flashes on screen, printed in ink that may or may not match what it says. Press Match if the word and its ink color agree, and No Match if they clash. You have 30 seconds to rack up as many correct calls as you can, and a wrong answer resets your streak, so accuracy beats panic.
