Universitat de Barcelona, Barcelona, Spain Abstract Numerous research efforts have been directed toward determining the origin of anisotropies of visual space, in contrast to real space.
Recent neurophysiological studies have placed the origin in the primary visual cortex (V1) or beyond.
The present study sought to provide new psychophysical evidence of the origin of these anisotropies using auto-stereograms as visual stimuli in a relative depth judgment task.
The observers were presented with a hidden three-dimensional shape that consisted of two pairs of parallel line segments that were located in different depth planes and oriented at 0° (horizontal line segments), 45°, and 90° (vertical line segments).
The influence of orientation on the visual performance of five observers was evaluated.
The encountered differ...
