Learn about divided attention, selective attention, inattentional blindness, & change blindness. By Carole Yue. . Created by Carole Yue.


Alright, I'm going to start out with a challenge for you, I'm going to show you a series of shapes. And I want you to count the number of yellow stars that you see. also count the number of red x's that pop up on the screen. So that's two separate numbers, one for how many yellow stars you see, and one for how many red X's come up on the screen.

Alright, so that was probably a challenging task, because you had to count two different things. And I kept talking to you while you were trying to do that. That's an example of divided attention, which we'll talk about in just a second. But first, you probably want to see how you did. So let me show you everything that you just saw. All right. This is everything that popped up on your screen, there were 15, yellow stars, and 13, red x's. And also, one smiley face. Don't worry if you didn't see this guy. We'll talk about that later.
