Stroop Effect Test

What is the Stroop effect?

American psychologist John Ridley Stroop published a study on the effect named after him in 1935. Stroop conducted an experiment. He gave the subjects a list in which the color of the word and its meaning did not match (for example, the word "yellow" is written in red).

Participants were asked to name the color of the ink used to print the words. According to the theory, our brain saves resources and “automatically” reads familiar words. Therefore, this task caused the greatest difficulties for people who knew the language in which the names of the colors were written. The subjects gave answers with a delay, often confusing written and actual colors.

The Stroop test was most popular in the United States during the Cold War. Using inscriptions in Russian, it was easy to determine whether a person understands this language or not.

Can you pass the Stroop test?

This test seems very simple, but in fact, only 5% of people can pass it without errors!

Testing based on the Stroop experiment is actively used in psychology to determine the flexibility of cognitive thinking. If a person can quickly switch from reading words to indicating colors, then their cognitive thinking is quite flexible. The point is precisely in the contradiction between the information read and the information seen.


Choose the answer that correctly indicates the color of the inscription, regardless of the meaning of the word itself. You have one minute to complete the test, and your task is to give as many correct answers as possible during this time.
