I read the book. Basically, when your child behaves in a way you don't like you start counting "That's 1" if they don't stop you continue "That's 2" and once you say "That's 3" you take them to their room for time out. The author advocates locking them in their room if they don't stay. My understanding of the specific technique is that it doesn't allow much for actual teaching and allowing the child to learn. You just count and if the child doesn't comply they get punished.
