Illusion Help?

Question

how can you demonstrate a project on the question... Why do unanimated optical illusions appear to move?

Answer 1

This actually depends on the nature of the illusion, as different illusions have different reasons for their apparent movement (or other characteristics).

A good place to start is the Wikipeida article linked below. While I don't support citing Wikipedia in any sort of academic work, it's a good place to begin looking into the various studies that have been done on this issue. As a side note, while this relates to optics in physics, it's probably more directly related to physiology.

Hope this helps you!
