Curvature of Binocular Visual Space An Experiment

Abstract

The sign of the curvature of any geometry is an intrinsic property independent of its coordinatization. Accordingly, it is possible in principle to determine the sign of the curvature of binocular visual space without employing knowledge of the particular relationship between the physical stimulus and the associated visual geometry. A simple experiment for making this determination is described and the outcome for a number of observers is presented. For most of the observers the indicated curvature is negative, in agreement with the preponderance of earlier findings.
