A teacher at my school once told me/the class that he hits his children when they're very naughty.
Of course he doesn't mean belting them, but a firm slap that will hurt, but not badly, if you understand.
He only hits them though, because he believes it's a natural idea.
He used the brown townogy of a child, or anyone, doing something bad and getting hurt.
Say you stick your hand in a fire. It hurts, a lot. It hurts and that pain sticks in your mind and you don't ever do it again. It's your body and brain's way of telling you that what you've done is dangerous and it is not good to do.
So, he sees the idea of making a child feel a light bit of physical pain for doing something very naughty as a natural idea, as that bit of pain also sticks into your mind, and the child know's that what they have done is dangerous for them and will get them hurt.
Which is true, because in cases where someone is so bad that they need a little physical punishment, it is generally based on the child having done something dangerous, whether that is physically dangerous, or even a crime, which has it's dangers.
