Level 2: Classic Stroop

How this level works

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.

Example: if you see BLUE, you should click GREEN because the word is written in green ink.

Take a breath, focus on color only, and then start when you are ready.

Level 2: Classic Stroop Test
IGNORE the word - Click the COLOR you see!
COLOR

Level 3: Speed Challenge

What changes in this level

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.

Level 3: Speed Challenge
Click the COLOR quickly - You have 3 seconds per word!

Level 4: Reverse Challenge

What changes in this level

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.

Level 4: Reverse Challenge
IGNORE the color - Click the WORD you read!
WORD

Level 5: Ultimate Challenge

What changes in this level

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.

Level 5: Ultimate Challenge
Follow the instruction for each word!

📊 How You Compare to Research Data

Official Stroop scoring uses only Level 1 (baseline) and Level 2 (conflict). Levels 3-5 are extension rounds and do not change the official Stroop score.

🧠 Clinical Context: The Stroop Test in Cognitive Assessment

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:

  • Early Detection: The Stroop test can help detect mild cognitive impairment and early dementia
  • Normal Aging: Some slowing with age is normal - the interference effect typically doubles from age 20 to 70
  • Clinical Threshold: Unusually large interference effects (>200ms) or very poor accuracy (<90%) may warrant professional assessment
  • Victoria Stroop Test: A shortened clinical version is specifically designed for elderly populations

Note: This game is for educational purposes only and not a diagnostic tool. Consult healthcare professionals for any cognitive concerns.

Reflection Questions - Answer these for your assignment:

1. Which level was hardest? Why do you think that was?
2. Did you get faster or slower when the word and color didn't match?
3. What does this tell us about how your brain processes attention and automatic responses?
4. How might the Stroop Effect apply to real-world situations like driving or studying?
