Test Your Cognitive Control Abilities
Through the classic Stroop test, explore how the brain processes conflicting information and measure your reaction time and attention control abilities.
Start Stroop Test
Select a test mode to begin. Focus on the color of the text, not what the word says.
Test Rules
Color words will appear on screen (like "red", "blue", etc.)
Words will be displayed in different colors (may not match the word meaning)
Click the button that matches the text color, ignore the word content
Answer each question as quickly and accurately as possible

What is the Stroop Effect?
The Stroop effect is a psychological phenomenon where cognitive conflict occurs when we see color words (like "red") displayed in different colors, causing delayed reaction times and increased error rates.
This effect reveals an important characteristic of human cognition: reading is such an automated process that we find it difficult to suppress the processing of word content, even when the task requires us to ignore it.
The strength of the Stroop effect reflects an individual's cognitive control ability, which is the brain's capacity to suppress irrelevant information and focus on relevant tasks.
Effect Demonstration
Congruent Condition (Easy)
Text and color match, faster response
Incongruent Condition (Difficult)
Text and color conflict, slower response
Historical Background
John Ridley Stroop's Discovery
American psychologist John Ridley Stroop first systematically studied this phenomenon in his doctoral thesis, publishing the classic paper "Studies of interference in serial verbal reactions."
Modern Applications
Today, the Stroop test has become one of the most important tools in cognitive psychology and neuroscience research, widely used in clinical diagnosis, educational assessment, and basic research.
Important Milestones
Scientific Principles
Automatic Processing
For skilled readers, reading is a highly automated process. The brain involuntarily processes textual information, even when it's irrelevant to the current task.
Cognitive Control
Completing the Stroop task requires the brain's executive control system to suppress automatic reading responses and focus on color recognition tasks.
Neural Mechanisms
Brain imaging studies show enhanced activity in the anterior cingulate cortex and prefrontal cortex when processing Stroop conflicts.
Individual Differences
The strength of the Stroop effect varies among individuals and correlates with age, cognitive abilities, and attention control capabilities.
Application Fields
Cognitive Psychology Research
Study attention, cognitive control, and information processing mechanisms
Clinical Assessment
Assess cognitive function in ADHD, depression, dementia, and other conditions
Educational Research
Understand reading development and bilingual language processing abilities
Occupational Screening
Assess job suitability for roles requiring high attention concentration
Stroop Effect on Daily Life
Driving Safety
When road sign colors don't match text information, it may cause delayed reaction times, affecting driving safety and decision speed.
Reading Comprehension
Colored text and highlighting affect reading speed and comprehension efficiency; proper color schemes aid information acquisition.
User Interface Design
Color-text matching in websites and apps affects user experience; good visual design reduces cognitive load.
Advertising Design
Color choices in advertising directly affect information delivery effectiveness; clever use of the Stroop effect can enhance memory and attention.
Educational Materials
Color coding and text design in textbooks affect learning outcomes; proper visual hierarchy aids knowledge understanding and retention.
Product Packaging
Color-brand information consistency in packaging design affects consumer cognition; reducing confusion improves brand recognition.
Test Tips and Suggestions
Focus on Colors
Always focus on the color of the text, not the word content. This requires conscious effort to suppress automatic reading responses.
Quick Response
React as quickly as possible, but don't sacrifice accuracy. The balance between speed and accuracy is key.
Stay Focused
Maintain concentration throughout the test, avoid distractions or thinking about other things.
Practice Improves
Performance can improve with repeated practice, but the Stroop effect typically doesn't disappear completely.
