Macrocognition is like when we play a big game like hide-and-seek with a lot of people. To play the game well, we have to think about different things - like where we should hide or how to find our friends who are hiding. This kind of thinking is called "macrocognition".
And just like that game, many things in life need macrocognition! For example, when adults go to work, they also have to think about lots of things at the same time - like what tasks they need to finish or how to work well in teams with their coworkers.
So, macrocognition is a big word for a kind of thinking that helps us manage complicated situations by considering many different things at once!
