Many critical perceptual judgments, from telling whether fruit is ripe to determining whether
the ground is slippery, involve estimating the material properties of surfaces. Very little is …

The biological basis for regional and inter-species differences in cerebral cortical morphology
is poorly understood. We focused on consanguineous Turkish families with a single …

The biological basis for the development of the cerebro-cerebellar structures required for
posture and gait in humans is poorly understood. We investigated a large consanguineous …

The light reflected from a glossy surface depends on the reflectance properties of that surface
as well as the flow of light in the scene, the light field. We asked four observers to compare …

Haptic research has frequently equated softness with the compliance of elastic objects. However,
in a recent study we have suggested that compliance is not the only perceived material …

We investigated whether people who report different colors for# thedress do so because
they have different assumptions about the illumination in# thedress scene. We introduced a …

Research on the visual perception of materials has mostly focused on the surface qualities
of rigid objects. The perception of substance like materials is less explored. Here, we …

We investigate how human observers make use of three candidate cues in their lightness
judgments. Each cue potentially provides information about the spatial distribution of light …

We examined the effect of perceived orientation on the perceived color of matte surfaces in
rendered three-dimensional scenes illuminated by a blue diffuse light and a yellow punctate …

Haptic research has traditionally often equated softness with compliance. However, in a
recent study we have suggested that compliance is not the only perceived object dimension …
