title: The apparent size of three-dimensional objects and their silhouettes: a solid-superiority effect.
abstract: A solid object looks larger than its outline or silhouette under many viewing conditions. This solid-superiority effect may result from the assimilation or confusion of visual contours within the projection of a three-dimensional object on the picture plane. An aspect of the Müller-Lyer illusion may also play a role.
