What is the Stroop Effect?
The science behind the game
The Stroop Effect is a psychological phenomenon that demonstrates the interference in reaction time when automatic processes conflict with controlled processes. Named after John Ridley Stroop, who first published the effect in 1935, this cognitive test reveals how our brain processes conflicting information.
When you see a word written in a color that doesn't match its meaning (like the word "RED" written in blue ink), your brain experiences interference. Reading is an automatic process, while identifying colors requires more conscious effort, creating a cognitive conflict that slows down your response time.
