Nice work. That was just warm-up. Now we run the real test and measure your speed.
In this level, ignore the word itself and choose the ink color. Your job is to click the button that matches the color you see, not what the letters spell.
Take a breath, focus on color only, and then start when you are ready.
This is the same Stroop task from Level 2, but now you are on a timer. You get 3 seconds for each word.
Keep ignoring the word text and click the ink color. If time runs out, that trial counts as a miss and moves on.
Stay calm, trust what you see, and focus on clean fast answers.
This one flips the rule. Do not pick the ink color. You now click the button for the word you read.
Example: if you see the word BLUE, you click BLUE even though the ink is green.
Slow down for the first few prompts, then build speed.
The rule changes every prompt. Watch the yellow instruction label above the word.
If it says COLOR, click the ink color. If it says WORD, click the word text.
Read the instruction first on every trial. Accuracy matters more than guessing fast.
The Stroop test is widely used in clinical settings to assess cognitive function. While our game is for educational purposes only, here's what research shows:
