Stroop effect

Hey there! Do you know what the Stroop effect is? It's when our brains get confused! Here's how it works:

Imagine you're looking at a picture of a BLUE fish, but the word under the picture says "RED." What color do you think of when you see the word "RED?" Right, you think of the color red. This is where the Stroop effect comes in.

Now, let's try another one. You see the same blue fish, but this time the word under it says "BLUE." What color do you think of when you see the word "BLUE?" That's right, you think of the color blue.

So, when the color of the word matches the color of the object, it's easy to read the word and say what color it is. But when the color of the word and the color of the object are different, our brains get confused and have to work harder to figure it out.

Scientists discovered the Stroop effect a long time ago, and they still use it today to learn more about the brain and how it works. Pretty interesting, huh?
