Game logic
A run contains 12 rounds. EgoTools records whether each colour answer is correct and separately measures response time from presentation to choice.

HOW THE GAME SCORES
Stroop Test
Choose the ink colour of each word while ignoring what the word itself says. The conflict between reading and colour naming creates the classic Stroop-style interference.
Reading your score
Correct answers and average response time answer different questions, so both are shown. The saved best tracks correct answers rather than hiding accuracy inside a combined mystery score.
Worked example
A run can be 11/12 correct with a 620 ms average. Another run may be 9/12 at 450 ms; neither number alone tells the full story.
Good to know
This is an informal browser implementation, not a controlled neuropsychological test. Language, display and input device can affect performance.
UNDERSTAND YOUR RESULT
The word is automatic; the task asks you to ignore it
In a Stroop-style task, the meaning of a color word can conflict with the color of the ink. The delay and mistakes created by that conflict are a classic demonstration of interference in attention and response selection.
Congruent trials feel easy
When the word RED is displayed in red, reading and color naming point toward the same response. There is little conflict to resolve.
Incongruent trials create interference
When RED appears in blue, the automatic tendency to process the word competes with the instruction to report the ink color.
Speed and errors both matter
Rushing can reduce response time while increasing mistakes. A useful result looks at both pace and accuracy rather than celebrating one fast click.
Practice changes the experience
Once you understand the rule and repeat the game, task familiarity can reduce hesitation. Compare sessions with similar practice levels.
| Signal | What it is useful for | Important limitation |
|---|---|---|
| Congruent | Word and ink agree | Usually easier |
| Incongruent | Word and ink conflict | Usually more interference |
| Reaction time | Response speed | Affected by caution and device |
| Accuracy | Rule-following under conflict | Can fall when rushing |
The Stroop effect is real; this score is still a mini-game
The phenomenon has a long research history, but EgoTools is not administering a standardized neuropsychological Stroop test.
