About the Stroop Test

The Stroop task measures interference control: your ability to suppress the automatic impulse to read a word and instead report the ink color. The score reflects mainly accuracy, with a smaller contribution from response speed.

What it measures

Methodology

Scoring

Points are computed from accuracy, with a small bonus for faster correct responses. This makes the score harder to game by rushing and guessing.

FAQ

Why is my score inconsistent?

Attention, fatigue, stress, and distractions can noticeably affect interference control. Compare averages across multiple runs rather than single attempts.

Does a higher refresh rate or faster device matter?

Yes, slightly. Device latency and input lag can affect response timing. For fair tracking, test on the same device and browser.

Is this an IQ test?

No. Stroop measures one narrow aspect of executive function (inhibitory control). It is not a diagnostic or a full cognitive assessment.

Can I improve my performance?

Most people can improve consistency and reduce slow outliers with short regular practice and good sleep. Big improvements usually come from fewer mistakes, not extreme speed.
