Stroop Effect
Stroop Effect is when reading a color word slows you down from naming the ink color it is printed in.
You have a tray of red blocks with a sign that says "Blue" taped to the front. Your job is to say the color of each block out loud. Your brain reads the sign first, so it wants to say "Blue" even though the block is red. That mix-up slows you down each time the label and the color clash.
Explaining stroop effect by grade level
Think about the word "red" printed in blue ink. You try to say the ink color, blue. But your brain reads "red" first and slows you down. Your brain wants to read so much that it gets in the way.

Your brain reads words automatically, even when you try to ignore them. That automatic reading slows you down when you name the ink color of a mismatched color word. In one test, participants read ink colors out loud while ignoring the word meaning. Females averaged about 35.7 seconds while males averaged about 46.9 seconds, showing that some people resist this interference better than others.
The interference between word reading and ink naming can be measured by comparing tasks with and without word-color conflict. You give 60 participants three tests: first reading color names printed in black, then reading color names printed in mismatched colors, and finally saying the ink color instead of the word. Participants range from age 10 to 60, each group getting 30 seconds per test. Younger participants score higher on all three, but the biggest gap appears on the hardest test — where they must ignore the word and name the ink color.
