About Stroop Test

A colour-word challenge asks you to answer one thing while looking at another. In this Stroop Test, the word on screen names a colour, but its ink may be the same colour or a different one. Your job is simple: choose the ink colour, not the word you are reading. The page presents a fixed twelve-trial route, so you can see exactly what kind of activity you are playing rather than being placed into an opaque score system. Six trials use matching word and ink colours. Six use conflicting combinations. The mix gives the final screen two transparent averages to compare.

Start the route when you are ready. A large word appears in coloured ink, followed by four plainly labelled colour buttons. You can tap or click a button on any device. On a keyboard, R, B, G, and Y select red, blue, green, and yellow. The keyboard shortcuts are an optional convenience, never the only way to play. The game accepts one response per visible trial, immediately moves to the next item, and freezes the finished route so an accidental extra click cannot alter the summary. Restart creates a fresh route using the same disclosed fixtures.

The result screen reports matching-colour average response time, conflicting-colour average response time, and their difference. The page calls that difference an interference index because it is simply the conflicting average minus the matching average for this one browser-game route. It is not compared with another person, an age group, a population, or a published norm. A correct answer counter and accuracy percentage are also shown so a fast route with many wrong answers is not presented as automatically better. Browser timing can be reduced in precision by a device or browser, which is another reason to treat the values as play-session feedback rather than an instrument reading.

The route protects a common timing pitfall. If the tab becomes hidden, the current trial pauses. Background time is not added to the next visible response. When you return, choose Resume this trial to begin a new visible response interval for that same item. This makes the result easier to understand when a notification, call, or another app interrupts you. It does not make the route standardized; it only avoids describing a hidden-tab delay as a response.

This page is an entertainment exercise, not a clinical/IQ/cognitive assessment. It does not diagnose attention, measure intelligence, estimate a condition, or establish whether your brain has improved. The fixed colour-word route is a small interactive game with product-authored trials, not a treatment, screening, or professional evaluation. If you have a health, learning, or ability concern, this page cannot answer it. Use the result only as a record of this private round of play.

Everything happens locally in your browser. The tool does not ask for a name, account, profile, camera, microphone, or uploaded file. A best score may be saved in this browser through the shared game shell, but it is not sent to Lizely and can be cleared with normal browser storage controls. Related games such as number memory and visual memory offer different play patterns, but they remain separate entertainment activities rather than a combined assessment. Open the route, choose the ink colour, and use the final summary as a clear description of this one fixed game session.

Methodology & sources

The route contains six matching and six conflicting product-authored colour-word fixtures. The page records one visible-tab response per trial with the browser's monotonic timer, then reports simple within-route averages. It does not use a clinical protocol, score norm, or diagnostic threshold.

Frequently asked questions

Is this Stroop Test an IQ or cognitive assessment?
No. It is an entertainment exercise with a fixed product-authored route. It has no norm group, diagnosis, intelligence score, or clinical interpretation.
Why did the current trial pause?
The page pauses an active trial when the tab becomes hidden so time spent in another app is not included in the next visible response.
What does the interference index mean here?
It is the conflicting-colour average response time minus the matching-colour average from this one twelve-trial game. It is not compared with a population benchmark.
