Document Summary

All 3d objects can be decomposed into a bunch of simpler, geometric shapes called. Geons , which are described as the alphabet of object recognition. There are 36 geons that make up all of what we see. Features of 3d images that are almost always present in 2d viewpoints. A coin from the side would be an accidental viewpoint. If the object does not resemble something you recognize, you use mental rotation to rotate the object to a viewpoint that makes sense to you and is recognizable. There is evidence that face recognition happens in a different way than object recognition. Inversion effect: it is easier to recognize faces better when upright rather than when they are upside down. Great evidence for this in faces, but not so much in objects. This is evidence that face perception is somewhat holistic we tend to process faces as.
