How the human visual system determines the lightness of a surface, that is, its whiteness,
blackness, or grayness, remains--like vision in general--a mystery. In fact, we have not even …

Although lightness perception is clearly influenced by contextual factors, it is not known
whether knowledge about the reflectance of specific objects also affects their lightness …

Researchers studying surface color perception have typically used stimuli that consist of a
small number of matte patches (real or simulated) embedded in a plane perpendicular to the …

Abstract Levin and Banaji (Journal of Experimental Psychology: General, 135, 501–512,
2006) reported a lightness illusion in which participants appeared to perceive Black faces to …

The expression “experimental phenomenology” seems to be an oxymoron. Phenomenology,
in fact, understood as the science of phenomena, appearances, or subjective experiences …

Illumination varies greatly both across parts of a natural scene and as a function of time,
whereas the spectral reflectance function of surfaces remains more stable and is of much …

In daily life, we use color information to select objects that will best serve a particular goal
(eg, pick the best-tasting fruit or avoid spoiled food). This is challenging when judgments …

One critical question regarding visual cognition concerns how the physical properties of the
visual world are represented in early vision and then relayed to high-level vision. Here, we …

Extensive, very high quality outcrops on the southern flank of Jabal Shams, Oman
Mountains, expose the complex fracture and fault network of an exhumed high-pressure cell …

Lightness perception has mainly been studied with static scenes so far. This study presents
four experiments investigating lightness perception under dynamic illumination conditions …
