Stroop Test

Your brain wants to read the word. Your job is to ignore it.

• A color word appears in a different ink color.
• Click the button matching the ink color — not the word.
• You have 2 seconds per round. 10 rounds total.
• No answer in time counts as wrong.

The Stroop effect is one of the most replicated findings in cognitive psychology. When a word's meaning conflicts with its ink color, response times slow measurably — a direct measure of cognitive interference and selective attention.
