Cognitive illusions are assumed to arise by interaction with assumptions about the world, leading to "unconscious inferences", are commonly divided into ambiguous illusions, distorting illusions, paradox illusions, or fiction illusions.
Ambiguous illusions are pictures or objects that elicit a perceptual "switch" between the alternative interpretations.
Distorting or geometrical-optical illusions are characterized by distortions of size, length, position or curvature.
Paradox illusions are generated by objects that are paradoxical or impossible.
Fictions illusions are when a figure is perceived even though it is not in the stimulus.
