Gregory's Perspective Theory

Frage	Antworten
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.
Image: mli.gif (image/gif)	-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.
