A square appears deformed when we superimpose to it diverging rays (illustration 3.1); consequently, to the rays is ascribed the cause of deformation. But if we substitute a scalene triangle or a shapeless object for the square, no deformation is perceived (illustrations 3.3 and 3.4). The fact challenges the concept of "form£ in visual perception.
