Gee, I wrote about a number of points in my previous posting, but everyone seems to jump on my statement about cats! OK, I'll give it a shot... My basis for saying cats (that particular pet is just an example - I don't have anything out for cats!) can't learn is that just because it exhibits behaviour that LOOKS like learning, that doesn't NECESSARILY mean that it is learning. There's a lot of anti-behaviourist people in the AI field, but lots of them will say that as long as the behaviour exists, then the phenomenon exists. There's lots we don't know about how humans think. Even less about how cats think. We can say humans learn, but there are other explainations for the behaviour that cats display, such as a modification to a stimulus based on the hope/expectation of being fed. >Cats acquire data, remember past situations, and heuristically improve >on their responses to similar situations.

I've seen examples of this, but also counter examples. We used to have a cat we called the "Artichoke Cat", because her level of cognition was roughly equivalent to that very vegetable. This thing couldn't modifiy her behaviour if her life depended on it! - Jim Ruehlin
