Depth without disparity in random-dot stereograms.
Depth can be perceived in random-dot stereograms in which dots are binocularly uncorrelated, in the absence of overall positional disparity (e.g., Julesz, 1960). This phenomenon, which we have called rivaldepth, persists over a wide range of luminances, stereogram dot densities, and dot sizes. Rivaldepth is also observed with interocular uncorrelation provided by complementation and orthogonal ...
متن کاملLearning to see random-dot stereograms.
In the present study some specific properties of the learning effects reported for random-dot stereograms are examined. In experiment 1 the retinal position-specific learning effect was reproduced and in a follow-up experiment it was shown that the position specificity of learning can be accounted for by selective visual attention. In experiments 2 and 3 evidence was obtained that suggests that...
متن کاملHysteresis, cooperativity, and depth averaging in dynamic random-dot stereograms.
Experiments were performed to assess the response of the human visual system to dynamic random-dot patterns composed of disparity mixtures. In Experiment 1, the perceived depth and relative stability of two patterns were compared; one pattern depicted two transparent layers of dots, and the other depicted a volume of dots. Two effects were found: (1) the volume pattern exhibited a large degree ...
متن کاملDepth Perception Not Found in Human Observers for Static or Dynamic Anti-Correlated Random Dot Stereograms
One of the greatest challenges in visual neuroscience is that of linking neural activity with perceptual experience. In the case of binocular depth perception, important insights have been achieved through comparing neural responses and the perception of depth, for carefully selected stimuli. One of the most important types of stimulus that has been used here is the anti-correlated random dot s...
متن کاملQuantitative analysis of the responses of V1 neurons to horizontal disparity in dynamic random-dot stereograms.
Horizontal disparity tuning for dynamic random-dot stereograms was investigated for a large population of neurons (n = 787) in V1 of the awake macaque. Disparity sensitivity was quantified using a measure of the discriminability of the maximum and minimum points on the disparity tuning curve. This measure and others revealed a continuum of selectivity rather than separate populations of dispari...
