Segregation of Form , Color , Movement , and Depth : Anatomy , Physiology , and Perception MARGARET LIVINGSTONE

Segregation of form, color, movement, and depth: anatomy, physiology, and perception.

Anatomical and physiological observations in monkeys indicate that the primate visual system consists of several separate and independent subdivisions that analyze different aspects of the same retinal image: cells in cortical visual areas 1 and 2 and higher visual areas are segregated into three interdigitating subdivisions that differ in their selectivity for color, stereopsis, movement, and ...

Psychophysical evidence for separate channels for the perception of form, color, movement, and depth.

Physiological and anatomical findings in the primate visual system, as well as clinical evidence in humans, suggest that different components of visual information processing are segregated into largely independent parallel pathways. Such a segregation leads to certain predictions about human vision. In this paper we describe psychophysical experiments on the interactions of color, form, depth,...

Stereopsis and artistic talent: poor stereopsis among art students and established artists.

Color and Luminance Interactions in the Visual Perception of Motion and Depth

Livingstone and Hubel (1987, 1988) reviewed numerous studies showing that color does not provide essential information for the perception of motion and depth. However, recent studies have suggested that color signals do contribute to both perceptions (Simmons & Kingdom, 1994, 1995, 1997, 2002; Cropper & Derrington, 1996; Yoshizawa et al., 2000; Mullen et al., 2003; Michna et al., 2007). Since t...

Differences between stereopsis, interocular correlation and binocularity

In normal human subjects, evoked potentials in response to depth reversing two-color dynamic random-dot stereograms disappeared or were greatly reduced at equiluminance, whereas responses to shifts between patterns that were correlated and anticorrelated (for the two eyes) were, for most subjects, actually larger at equiluminance than at non-equiluminance. Responses were only slightly diminishe...
