I've just been discussing this with my boss. I was smacked, my mum used to threaten us with the wooden spoon ? which she did use a few times! I can't ever imagine her doing this now and it's strange to think of it.
I was never 'beaten' but did get the odd smack which whilst it didn't do me any harm I wouldn't say it did me any good. A far more effective method of punishment for me was if I knew that I had disappointed my parents, I used to feel awful.
