I think a short sharp jab to your face might be quite productive too. Oh wait, no that's absolute bull****, that would do nothing beneficial at all.
Suffice to say getting slapped didn't aid me. It didn't show me why what I was doing was wrong, especially when what you do is an accident. How can you get physically pounded in the face and ribs for accidentally breaking something? That's not moral. All it did was make me learn how to fight and also become aggressive with other people. I learnt that smashing people's faces in was a permissible way to behave if they detrimented me - even if they didn't MEAN to detriment me.
Terrible way to raise children and I shall not be raising my own that way.
