HOW TO PLAY

  1. Classic Stroop Effect Test - Test your cognitive flexibility and selective attention
  2. You'll see a color word (like "RED") displayed in a color
  3. Click the color you SEE, not what the word says
  4. Congruent trials: Word matches color (e.g., "RED" in red) - easier!
  5. Incongruent trials: Word doesn't match color (e.g., "RED" in blue) - harder!
  6. Each trial has a time limit - answer quickly but accurately
  7. Incongruent trials are worth more points because they require overcoming interference

About Stroop Test

The Stroop Test is a classic cognitive psychology experiment that measures selective attention, cognitive flexibility, and processing speed. In this test, you'll see color words (like "RED", "BLUE", "GREEN") displayed in different colors. Your task is to identify the color of the text, not the word itself. This creates cognitive interference - the Stroop effect - where your brain automatically wants to read the word instead of naming the color.

Final Score Formula:
(Base Points + Time Bonus) × Accuracy Multiplier

Incongruent trials are worth more points because they require greater cognitive control to overcome interference. Faster responses earn time bonuses, while wrong answers incur penalties.

Training Benefits

Selective Attention
Focus on relevant information while ignoring distractions
Cognitive Flexibility
Switch between conflicting mental processes
Processing Speed
Rapidly process and respond to visual information
Inhibitory Control
Suppress automatic responses and impulses
Response Inhibition
Control impulse to respond incorrectly
Executive Function
Strengthen higher-level cognitive control

Performance Tips

  • 1
    Focus on the COLOR of the text, not the word itself
  • 2
    Respond quickly but accurately - speed without accuracy loses points
  • 3
    Practice suppressing the automatic urge to read the word
  • 4
    Take a brief mental reset between trials to maintain focus
  • 5
    Incongruent trials are harder but worth more points - stay sharp!

Frequently Asked Questions

Q1
What is the Stroop effect?
The Stroop effect is a psychological phenomenon where it takes longer to name the color of a word when the word itself spells a different color (e.g., the word "RED" printed in blue). This demonstrates interference in the brain's processing of conflicting information.
Q2
What's the difference between congruent and incongruent trials?
Congruent trials show words where the text color matches the word (e.g., "RED" in red). Incongruent trials show mismatched combinations (e.g., "RED" in blue). Incongruent trials are harder and worth more points because they require cognitive control to overcome interference.
Q3
How does the difficulty change?
Easy: 30% incongruent trials, 3s per trial. Medium: 50% incongruent, 2s per trial. Hard: 70% incongruent, 1.5s per trial. Higher difficulties have more conflict trials and less time to respond.
Q4
What does the interference effect measure?
The interference effect shows how much your performance degrades on incongruent vs. congruent trials. A smaller interference effect indicates better cognitive control and the ability to suppress automatic responses. You'll see your interference metrics in the results screen.
Q5
Why is this test important?
The Stroop Test is widely used in psychology and neuroscience to assess executive function, cognitive flexibility, and attention. It helps measure your ability to control automatic responses and focus on task-relevant information - skills crucial for everyday decision-making and problem-solving.
