Perception and Action: A Closer Look at Two Theories
Young-Lim Lee

Shape perception is generally treated as a problem relevant to the ability to recognize objects. Alternatively, it is a problem that falls within the general domain of space perception and as such, the data from shape perception studies contributes to discussions about the geometry of visual space. This geometry is generally acknowledged not to be Euclidian, but instead, elliptical, hyperbolic or affine, which is to say, something that admits the distortions found in so many shape perception studies. In this article, I consider the repercussions of such understanding of perceived shape and the geometry of visual space in the context of visually guided action. Assuming that, then what does the need for information about surface shape to guide such actions imply about the current theory and results in the shape perception literature? Mainly, I compared two prominent approaches in perception and action, world model and control law approaches.
