What Is the Stroop Effect? Why Color Match Tests Are Tricky
The Stroop effect that appears when a word's meaning conflicts with its color, and what a color match test measures.
What it is
If the word 'red' is printed in blue, the word's meaning interferes when you try to name the color. This slowdown from a conflict between meaning and color is called the Stroop effect.
What it measures
A color match test checks not just raw speed but selective attention: suppressing the distracting information and focusing on what matters. That is why it feels harder than a simple reaction test.
Tips for a better run
Look at the text color before reading the word, and memorize the button positions to decide faster. Keeping your rhythm right after a mistake matters most.
