Stroop Test
The Stroop Test presents color words printed in conflicting ink colors (e.g., the word RED in blue). Naming the ink color β not reading the word β reveals the cognitive interference between reading and color naming.
Key Features
- Congruent and incongruent trials
- Reaction-time measurement
- Interference scoring
- Attention assessment
- 100% client-side
Use Cases
- Selective-attention checks
- Cognitive psychology demos
- Focus training
How to Use
- Read the instruction (name the ink color)
- Respond to each item quickly
- Mixed congruent/incongruent trials
- See your interference effect
- Repeat to compare
Practical Tips
- Say the color, not the word
- Expect incongruent items to slow you
- Stay relaxed
- Use for demonstration, not diagnosis
FAQ
- Why is it slower for mismatched?
- Reading is automatized; overriding it to name color creates interference.
- What does the effect measure?
- It estimates the cost of resolving competing responses β a marker of executive control.
