The Stroop Effect


What is the Stroop Effect?

The Stroop Effect was discovered in the 1930s by J. Ridley Stroop. It happens when words representing color are printed in a different color than the one they represent. For example the image below has red printed in blue and green is printed in yellow.

What happens when you try to read off the colors?

If you read off the words, there is not much trouble, but if you try to read off the colors the words are printed in it your brain has a bit more trouble with that.

This is because our brains are separated into different regions, and each region saw something different. The language region read the word and didn't register the color the word was written in. The color processing part only saw the color the word was written in. These two pieces of information arrived at the same processing region and becomes confused.
