ABSTRACT
The purpose of this paper is to discuss the role of geometry in determining the perception of spatial layout and perceived orientation in pictures viewed at an angle. This discussion derives from Cutting’s (1988) suggestion, based on his analysis of some of my data (Goldstein, 1987), that the changes in perceived orientation that occur when pictures are viewed at an angle can be explained in terms of geometrically produced changes in the picture’s virtual space. Before dealing with Cutting’s idea, let’s first consider the paper that stimulated it.
