Name the COLOR, not the word
You'll see color words displayed in different colors. Your task is to identify the color of the text, NOT what the word says.
For example, if you see RED, the correct answer is Blue (the color it's displayed in).
Challenge your brain with the famous Stroop Test, a classic psychological experiment that measures cognitive flexibility and processing speed. You'll see color words displayed in different colors - your task is to identify the ink color, not read the word. When you see "RED" written in blue, the correct answer is blue. Test your raw response speed with our reaction time test.
This interference effect occurs because reading is automatic, while color recognition requires conscious effort. The test offers 20, 40, or 60 rounds with keyboard shortcuts for faster responses. Track your score, accuracy, average response time, and fastest reaction to measure improvement. For word-based cognitive challenges, try our verbal memory test.
The Stroop effect demonstrates the competition between automatic and controlled processing in the brain. Regular practice can improve executive function, selective attention, and cognitive control - skills essential for multitasking, decision-making, and managing distractions. For another advanced cognitive test, explore our N-Back working memory game. This test is widely used in neuropsychological assessment and ADHD research.
