Through the classic Stroop test, explore how the brain processes conflicting information and measure your reaction time and attention control abilities.
Select a test mode to begin. Focus on the color of the text, not what the word says.
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

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.
Text and color match, faster response
Text and color conflict, slower response
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."
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.
For skilled readers, reading is a highly automated process. The brain involuntarily processes textual information, even when it's irrelevant to the current task.
Completing the Stroop task requires the brain's executive control system to suppress automatic reading responses and focus on color recognition tasks.
Brain imaging studies show enhanced activity in the anterior cingulate cortex and prefrontal cortex when processing Stroop conflicts.
The strength of the Stroop effect varies among individuals and correlates with age, cognitive abilities, and attention control capabilities.
Study attention, cognitive control, and information processing mechanisms
Assess cognitive function in ADHD, depression, dementia, and other conditions
Understand reading development and bilingual language processing abilities
Assess job suitability for roles requiring high attention concentration
When road sign colors don't match text information, it may cause delayed reaction times, affecting driving safety and decision speed.
Colored text and highlighting affect reading speed and comprehension efficiency; proper color schemes aid information acquisition.
Color-text matching in websites and apps affects user experience; good visual design reduces cognitive load.
Color choices in advertising directly affect information delivery effectiveness; clever use of the Stroop effect can enhance memory and attention.
Color coding and text design in textbooks affect learning outcomes; proper visual hierarchy aids knowledge understanding and retention.
Color-brand information consistency in packaging design affects consumer cognition; reducing confusion improves brand recognition.
Always focus on the color of the text, not the word content. This requires conscious effort to suppress automatic reading responses.
React as quickly as possible, but don't sacrifice accuracy. The balance between speed and accuracy is key.
Maintain concentration throughout the test, avoid distractions or thinking about other things.
Performance can improve with repeated practice, but the Stroop effect typically doesn't disappear completely.
The Stroop effect is a normal cognitive phenomenon that everyone experiences. Test results are influenced by various factors including age, educational background, language ability, etc. Don't over-interpret single test results; the average of multiple tests is more valuable for reference.
