- Start the test and get ready — each trial is quick.
- A color word appears printed in a different ink color, for example the word "red" shown in blue.
- Choose the INK color, not the word the text spells.
- Answer as fast as you can while staying accurate.
- When the run finishes, review your average reaction time and accuracy.
Frequently Asked Questions
What are the test rules?
Choose the color the word is actually displayed in (not its meaning). Half the trials are conflicting, better demonstrating the Stroop effect.
Which metrics are tracked?
Rounds completed, accuracy, average reaction time, and fastest reaction time.
Can I adjust the number of rounds?
Yes, 10, 20, or 30 rounds.
Is the data saved?
No. Results are shown only for that session and cleared on refresh.
What does the Stroop effect measure?
It measures how much automatic reading interferes with naming a color. The delay and errors on conflicting trials reflect the strength of that interference — a classic attention test.
What is a good reaction time?
Conflicting trials commonly land between roughly 700 and 1,000 milliseconds for casual attempts; lower is better, but accuracy matters as much as speed.
Does practice improve the score?
Some — repetition reduces the interference a little. The effect itself never disappears entirely, which is what makes the test reliable.
