cognitive illusions definition
A cognitive illusion can be defined as the viewer's knowledge and assumptions about the world, or unconscious inferences. There are three categories of cognitive illusions: ambiguous illusions, distorting illusions, and paradox, or fiction, illusions. Ambiguous illusions are images or objects that allow for the viewer to have two valid interpretations of what the object represents or what it actually is. The viewer is usually able to mentally visualize one interpretation right away and eventually the second, after some time.
