What is the Stroop Test?
The word “RED” printed in blue ink is surprisingly hard to name as “blue” – that delay is the Stroop effect, a famous psychology experiment about attention. In this game a colour word appears in a different ink colour: tap the button for the INK colour as fast as you can. You get 30 seconds; your score, accuracy and average reaction time are shown at the end.
How to use the Stroop Test
- Tap Start.
- Look at the ink colour (ignore what the word says).
- Tap the matching colour button – fast!
Did you know?
Reading is so automatic that your brain processes the word before you can stop it – that’s why the task feels tricky.
