What are automatic prolongations?

Automatic prolongations are like when your favorite toy keeps playing by itself, even after you stop pressing the buttons.

Imagine you have a robot dog that barks every time you press its tail. But one day, you notice that even after you let go of the tail, it keeps barking for a little while, almost like it’s remembering you pressed it! That's an automatic prolongation: the robot dog continues doing something on its own because it got started by your action.

Think about when you bounce a ball. At first, you have to throw it up to make it go. But once it starts bouncing, it keeps going, by itself, until it stops. That’s like how automatic prolongations work: something gets going because of an action you did, and then it continues on its own for a little while.

Inside the robot dog (or your toy), there's a kind of memory that helps it keep doing things even after you stop. Just like how you might still be thinking about a fun game even after you've stopped playing, your toy is doing something similar!
