Chimpanzies Don't Like Snakes

A story that emerged in solution to a problem i had been thinking about for a long time. This story popped into my head in one chunk like complete, which i thought was kind of interesting. It's also a representation of those stimuli that, if you're human, are going to make you both afraid and compelled. If you raise a rat to juvenile status and then waft in cat odor, it will completely short circuit. Why? Well, the rat's never seen a cat. So exactly what is it perceiving? In some sense, i think the notion that it's perceiving is wrong. It isn't perceiving. It's just going like this.
