Pavlov and Poker. Part 1

Do you remember learning about Pavlov back in Science class? The guy who did the experiments with the bells and the dogs? If you do, you'll remember that Pavlov trained his dogs to know they were about to be fed when he rang a bell. He knew they knew by the fact that whenever he rang the bell, the dogs would start salivating, even if he didn't have food for them. In fact, eliciting a Pavlovian response to your actions from your opponents is one of the best things you can do in poker.
