Motion can be perceived either through low-level, motion-energy detection or through
tracking the change in position of features. Previously we have shown that, while luminance …

A number of psychophysical and physiological studies have suggested that first-and second-
order motion signals are processed, at least initially, by independent pathways, and that the …

An isoluminant chromatic display is a color display in which the component colors have
been so carefully equated in luminance that they stimulate only color-sensitive perceptual …

International Series of Monographs in Experimental Psychology, Volume 16: Aspects of
Motion Perception details the fundamental concepts of the visual system perception of …

Motion of an object is thought to be perceived independently of the object's surface
properties. However, theoretical, neuropsychological and psychophysical observations have …

(I) Encoding of the third dimension (2) Time to collision (TTC)(3) Image segmentation (4)
Motion as a proprioceptive sense (5) Motion as a stimulus to drive eye movements (6) …

Distinct mechanisms underlying the visual perception of luminance-(first-order) and contrast-
defined (second-order) motion have been proposed from electrophysiological, human …

The visual motion aftereffect (MAE) was initially described after observation of movements in
the natural environment, like those seen in rivers and waterfalls: stationary objects appeared …

We measured perceived velocity as a function of contrast for luminance and isoluminant
sinusoidal gratings, luminance and isoluminant plaids, and second-order, amplitude …

This is a special issue dealing with mechanisms underlying human motion perception. A
novel feature is the inclusion of an Apple floppy disk so that readers can view some of the …
