title: Half-field asymmetry in visual perception of distance.
abstract: Distances were presented to the right and left halves of the visual field during steady fixation of a central point. Two methods of evaluation were used: direct scaling and the method of limits. A small but statistically significant difference was found between the estimates of distances presented to the left and to the right of the fixation point by direct scaling. No difference was found when the method of limits was used. The results are interpreted as evidence for the existence of functional asymmetry connected with the computation-and-speech ability of the hemispheres. No evidence for perception asymmetry could be found.
