Description:
Why do we need vision? On the one hand, we need vision to give us detailed knowledge of the world beyond ourselves, on the other hand, we also need vision to guide our actions in that world at the very moment they occur. The idea of two visual systems in a single brain might seem initially counter-intuitive. Our visual experience of the world is so compelling that it is hard to believe that some other quite independent visual signal, one that we are unaware of, is guiding our movements. After all, it seems obvious that it is the same subjective image that allows us both to recognize the coffee cup on our desk and to pick it up. But this belief is an illusion. As work with neurological patients shows us, the visual signals that give us our experience of the cup are not the same ones that guide our hand as we pick up it up! (M.A.G.)
