Pick the font color, ignore the word. Score combines accuracy and speed.
Choose the font color, ignore the word. Score is mainly driven by accuracy, with a smaller bonus for faster correct responses.
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.
Points are computed from accuracy, with a small bonus for faster correct responses. This makes the score harder to game by rushing and guessing.
Your run score is saved locally in your browser. This is a training/insight tool — not a medical device.
Attention, fatigue, stress, and distractions can noticeably affect interference control. Compare averages across multiple runs rather than single attempts.
Yes, slightly. Device latency and input lag can affect response timing. For fair tracking, test on the same device and browser.
No. Stroop measures one narrow aspect of executive function (inhibitory control). It is not a diagnostic or a full cognitive assessment.
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.
