About the Stroop Test
The Stroop test is a classic psychology task. Reading is automatic, so when the word RED is printed in blue ink your brain reads the word before it can name the color. Suppressing that habit takes concentration, and the delay shows up in every answer.
Answer as quickly and accurately as you can. A wrong tap briefly flashes red before the next word appears. At the end you get the number of correct answers, your accuracy and your average reaction time per question.
