Abstract

Decentration of stereoimages crossed makes a figure appear nearer and smaller; uncrossed makes it look larger and more remote. Quantification of these effects is presented with an orthogonal equation describing the interactions of distance from the observer, magnitudes of the decentrations crossed and uncrossed, and phenomenal judgment of apparent size. A 30- × 30-cm white square was photographed in orthostereo at distances of 3, 6, 12, 24, 48, and 96 m. Decentrations of 0 to 60 mm of the projected images in 10-mm steps were made and matched with an adjacent variable square. Some comment is made concerning the theoretical and practical bearings of the results.
