Stroop Color Test

Two question types will alternate:
What COLOR is the ink? (select the ink color)
What does the text SAY? (select the word itself)
Pay attention to the question — your brain will try to trick you!

The Stroop Effect

What Is It?

The Stroop effect (discovered by John Ridley Stroop in 1935) demonstrates that reading is so automatic that your brain struggles to ignore the word and focus on the ink color. This interference reveals how your brain processes conflicting information.

Why It Matters

The Stroop test measures cognitive flexibility, selective attention, and processing speed. It is widely used in psychology and neuroscience research, and even in clinical assessments for conditions like ADHD, dementia, and brain injuries.
