I wasn't a problem child either, but still I got spanked and sometimes slapped. I remember that I had to put up my finger (i don't know what you call that, like in school), when the adults were talking and I wanted to say something. May sound horrible, but in hindsight it taught me respect and manners, and it surely didn't damage me.
I grew up learning to respect others and use my manners. But I think it's the atmosphere I grew up in, the way my parents brought us up and the fact that I was put into religious classes that emphasizes manners and treatment of others at a young age (not saying that religion and religious classes are the only things that teach good manners and respect). Although I wasn't hit as a child, I'm not totally against it either. Just enough to teach a Lesson and anything more is straight up abuse.
But when we did do stupid or annoying things we got 'the eyes'
Use as much force as is necessary, and only when necessary.
