What is self-interaction?

Self-interaction is when something affects itself, just like when you give yourself a hug.

Imagine you have a toy car that can move on its own. Now, suppose this toy car has a special button, when it presses the button, it makes itself go faster. That's self-interaction! The car doesn't need another toy or person to help it; it uses its own power to make itself move more.

Think about when you're trying to solve a puzzle by yourself. You might say, “Okay, let me try this piece,” and then say, “No, that doesn’t fit.” You’re using your brain to help you figure out the answer, that’s like self-interaction too! You don't need someone else to tell you what to do.

Sometimes things can even be confused by self-interaction. Like if the toy car keeps pressing its own button, it might go so fast it crashes into a wall, all because it was trying to help itself!
