The Senses Considered as Perceptual Systems was fantastic, so I was hoping that this, one of Gibson's later books, would be even better. Instead, I found that the more recent writing concentrated on the parts of the older work that I didn't like . Gibson seems to entirely disregard the importance of preconceptions on perception; in particular, he doesn't write at all about how our models of the world affect our exploration of it. Particularly when listening, and I think also when looking, familiarity with the events under consideration affects perception immensely. He doesn't write about context either, which is disappointing. Overall, this is still a good book — and worth reading — but not as good as I expected.
