Vision Research, 2013 Older adults commonly report difficulties in visual tasks of everyday living that involve visual clutter, secondary task demands, and time sensitive responses. These difficulties often cannot be attributed to visual sensory impairment. Techniques for measuring visual processing speed under divided attention conditions and among visual distractors have ...

Visualizing processes on the web
Journal of Visual Languages & Computing, 2007In this paper, we describe 3WPS, a framework to build distributed systems that are able to monitor and interact with a process through a 3D interface that is accessible via the World Wide Web (WWW). The 3WPS is easily configurable, easily adaptable to different processes with high reuse of its software components and its distributed architecture ...

IEEE Computer Graphics and Applications, 1986
An increasingly important use of computer graphics is to monitor such real-world processes as manufacturing plants, power plants, and refineries. As in many uses of computer graphics, the development of this application area has been programmer-intensive.

Visual processing in migraineurs
Brain, 1995Twelve migraine subjects with aura and 12 matched control subjects performed four computerized visual tasks. Because chronic electroencephalographic and regional cerebral blood flow abnormalities in posterior brain functions have been documented during interictal periods, migraine subjects were tested between migraine attacks.

Conceptual Penetration of Visual Processing [PDF]
Psychological Science, 2010 In traditional hierarchical models of information processing, visual representations feed into conceptual systems, but conceptual categories do not exert an influence on visual processing. We provide evidence, across four experiments, that conceptual information can in fact penetrate early visual processing, rather than merely biasing the output of ...

Visual processing speed: effects of auditory input on visual processing
Developmental Science, 2007AbstractThe ability to process simultaneously presented auditory and visual information is a necessary component underlying many cognitive tasks. While this ability is often taken for granted, there is evidence that under many conditions auditory input attenuates processing of corresponding visual input.

ATTENTIONAL MODULATION OF VISUAL PROCESSING
Annual Review of Neuroscience, 2004▪ Abstract Single-unit recording studies in the macaque have carefully documented the modulatory effects of attention on the response properties of visual cortical neurons. Attention produces qualitatively different effects on firing rate, depending on whether a stimulus appears alone or accompanied by distracters.

Scientific American, 1983
Isoluminant stimulus is an image whose edges are defined only by a change in color, not by change in brightness. The stimulus here is imperfect: the blue parts and the green parts of the image are only as nearly equal in brightness as they can be on the printed page.

On the biochemical mechanism of the visual process
Experimental Eye Research, 1967Evidence is presented supporting an ionic mechanism for the stimulation of the photoreceptor by light. Illumination of a rhodopsin monolayer at an air-water interface causes expansion of the layer, which can be interpreted as the result of penetration of the monolayer by retinal.
