What is Gregory's theory? | That we interpret 2D illusions as if they were part of our 3D world using monocular depth cues. We then apply size constancy scale and distort the illusion. |

-We misinterpret the 2D illusion as the 3D world. -The fins are used as cues to linear perspective. -We consequently use size constancy scaling as if the scene really had depth. -Because we recognise that one line is closer ( the outside of the room) we use size constancy scaling to scale it down and perceive it as smaller. |
Limitations of the Gregory theory | -Contrasts with Gestalts theory of the Muller-Lyer illusion, and when fins are replaced with circles according to Gestalt it should not work. -Gestalt theory can explain more fiction and Ambiguous figures and therefore represents a better explanation. |
What are the strengths of Gregory's theory? | -Explains more distortion illusions (in terms of linear perspective) and therefore represents a better explanation of distortions. -Can explain SOME fictions. -Can explain SOME ambiguous figures. |
Gregory's theory on Ambiguous figures and fictions | -It can explain some AF such as the Necker Cube which uses depth cues to suggest the box can either be inward or outward. -Explain some fiction such as making shapes from displaced lines due to depth H-I-T-P. |
