The Stroop Effect Test
The Stroop Effect is the delay you feel when a word's meaning fights the colour you must name. Reading is automatic; colour-naming takes effort. This page turns that classic psychology effect into a timed challenge. The effect traces to John Ridley Stroop's 1935 research. Try it here by naming each displayed colour as quickly and accurately as you can.
Stroop Effect Test FAQ
What is the Stroop Effect test?
The Stroop Effect test is a colour and word challenge. You identify the colour you see while ignoring the written word. When the word and colour conflict, responses often slow down or become less accurate.
Why is it so hard to say the colour instead of reading the word?
For fluent readers, reading a familiar word happens quickly and automatically. Naming its display colour takes more deliberate attention, so the word can interfere when its meaning and colour disagree.
How fast is a good score?
There is no universal good score for this game. Your result depends on the rules, device, pace, and mistakes. Use the score to compare your own attempts under the same conditions, not as a clinical benchmark.
Is this a clinical or diagnostic test?
No. This is a game and demonstration, not a medical assessment. It cannot diagnose a condition or replace evaluation by a qualified health professional.
Where can I play the Stroop Effect as a party game?
Play FTG (F**k. The Game), the party game built on the Stroop Effect. Read about how the Stroop Effect powers a party game, then see F**k. The Game - the party game built on the Stroop Effect.
