ABSTRACT
The field of Artificial Intelligence has produced so many new concepts — or at least vivid and more structured versions of old concepts —that it would be surprising if none of them turned out to be of value to students of animal behavior. Notice that the success or failure of the intentional stance as a predictor is so neutral with regard to design that it does not distinguish von Kempelen's midget-in-the-works design from, say, Berliner's Hitech, a current chess program of considerable power. For instance, the vertical symmetry detectors that are ubiquitous machinery in animal vision are baffling until the people consider them, as Braitenberg recommends, as quick-and-dirty discriminators of the ecologically important datum that some other organism is looking at me. In particular, it is often next to impossible in the field to establish that particular monkeys have been shielded from a particular bit of information.
