Well I cannot really speak to any personal experience here, but I am very curious now, and I am thinking that I really have to try something like this. With my luck I am sure my little guy will take it as a sign of weakness on my part and then he will just go crazy, but you never know I suppose. It makes sense, and if things go right I might be able to perform some experiments and see how smart my guy actually is. If nothing else, though, this is really interesting and it is really fun to think about how they might respond to stimuli the same ways that we do. Very fascinating, and thanks for sharing.
