Lightness of induced mappings

Atomic Mappings Can Spoil Lightness of Open Mappings

We study continua on which each nonconstant open mapping is light. W. Makuchowski asked if this property is preserved under atomic mappings. It is known that this is true under an additional assumption of arcwise connectedness of the domain continuum. We show that in general this is not true.

Synesthesia-like mappings of lightness, pitch, and melodic interval.

Synesthesia-like mappings between visual lightness and auditory pitch and between visual lightness and melodic interval were examined. When subjects rated how visual lightnesses and auditory pitches "fit together," lighter stimuli fit better with higher pitches, and darker stimuli fit better with lower pitches. These patterns were stronger against black than against white visual backgrounds; ho...

24 Lightness Perception and Lightness Illusions EDWARD

The amount of light coming to the eye from an object depends on the amount of light striking the surface, and on the proportion of light that is reflected. If a visual system only made a single measurement of luminance, acting as a pho-tometer, then there would be no way to distinguish a white surface in dim light from a black surface in bright light. Yet humans can usually do so, and this skil...
