It all depends on the child. Some children are devastated if you just give them a disappointed look. Others, you can restrict them and take everything away from them but their arms and legs and nothing phases them. They need something more (but not abuse of course).
I remember my dad spanked me until I was about 8 yrs old...then one day he told me to go to my room and wait for him to come to give me the spanking. I took a dinnerplate with me and stuck it in my pants. He said he realized then that I was getting too old for spankings.
