In various cultures and at all spatial scales, humans produce a rich complexity of geometric
shapes such as lines, circles or spirals. Here, we propose that humans possess a language …

During language processing, humans form complex embedded representations from
sequential inputs. Here, we ask whether a “geometrical language” with recursive embedding …

Why is it that we can recognize object identity and 3D shape from line drawings, even
though they do not exist in the natural world? This article hypothesizes that the human visual …

How do we recognize objects despite differences in their retinal projections when they are
seen at different orientations? Marr and Nishihara (1978) proposed that shapes are …

Natural language is often seen as the single factor that explains the cognitive singularity of
the human species. Instead, we propose that humans possess multiple internal languages …

Advances in graphical technology have now made it possible for us to interact with
information in innovative ways, most notably by exploring multimedia environments and by …

A new account of how we perceive the 3D shapes of objects and how to design machines
that can see shapes the way we do. The uniqueness of shape as a perceptual property lies …

Shape grammars provide a means for the recursive specification of shapes. The formalism
for shape grammars is designed to be easily usable and understandable by people and at …

The present work aimed to systematically examine sensory and higher level
correspondences to angular and curved shapes. Participants matched angular and curved …

The mathematics of shape has a long history in the fields of differential geometry and
topology. But does this theory of shape address the central problem of vision: finding the …
