Excellent! I think illusions are possible because our brains do not keep, or perhaps do not even acquire, all details of a representation. I am sure you know more about this if you are in cognition, but it seems to me that vision acquires the most salient details first, creates an initial invrep, and later, if it is worth, that is if the picture repeats itself many times, it acquires more detail and supplements the invrep. Which tells us a feature of mental invreps: they are not only invariant, but they can also be supplemented.
Inadvertently, you have answered a question I have been asking from myself. Are Mike's JPG files invreps or not? They are invariant in 2D, I can turn them to any angle. But it would be very, very hard to supplement them. They are not invreps.

Representations in cognition aren't perfectly invariant, but they are pretty invariant under most commonly encountered conditions. http://www.youtube.com/watch?v=jdADSx8JpfI ------------------------------------------- AGI Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/18883996-f0d58d57 Modify Your Subscription: https://www.listbox.com/member/?&; Powered by Listbox: http://www.listbox.com ------------------------------------------- AGI Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/21088071-c97d2393 Modify Your Subscription: https://www.listbox.com/member/?member_id=21088071&id_secret=21088071-2484a968 Powered by Listbox: http://www.listbox.com
