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—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.
