Associated phoria in relation to stereopsis with random-dot stereograms.
In the present work, we use random-dot stereograms to test a possible relationship between associated phoria and stereopsis. We determined, using a modified constant-stimulus method, the disparity range that indicates the maximum range at which stereoscopic correspondence can be achieved. A total of 27 observers took part in the experiment. The value of the disparity range as a function of the ...
متن کاملdmax for stereopsis and motion in random dot displays
The upper displacement limit for motion was compared with the upper disparity limit for stereopsis using two-frame random dot kinematograms or briefly presented stereograms. dmax (the disparity/displacement at which subjects make 20% errors in a forced-choice paradigm) was found to be very similar for motion and stereo at all dot densities, and to fall with increasing dot density (0.006% or two...
متن کاملOcclusion contributes to temporal processing differences between crossed and uncrossed stereopsis in random-dot displays
Stereoscopic depth discrimination was investigated in crossed and uncrossed directions using stimuli defined by binocular disparity differences embedded in dynamic random-dot stereograms. Across three experiments, fixation was directed to a point on the display screen (which placed crossed stimuli in front of and uncrossed stimuli behind, the background dots of the stereogram), to a point in fr...
متن کاملStereopsis
When she becomes dominant her body changes so that she becomes physiologically and morphologically distinct from other non-reproductive female ‘workers’, even her bone structure changes. Mole-rats were thought to be the only mammal to do this, but it has since been discovered that female meerkats also develop elongated vertebra when they become dominant breeders. As well as reproductives, there...
متن کامل[A new objective test for random-dot stereopsis in preverbal children].
BACKGROUND The Lang-Stereotest is at best half-objective in testing stereovision in preverbal children. We developed a new method which might objectively measure random-dot stereopsis in preverbal children. PATIENTS AND METHODS We project two separate random-dot images into the left and right eye using a 3D-monitor. If both eyes are perfectly aligned and random stereopsis is present, the chil...
