SEVERAL previous investigations* have compared tests purporting to measure the
efficiency of binocular depth perception and have attempted by statistical procedures, ie, by …

The purpose of this study was to determine whether a motor adjustment (method of average
error) and a verbal response (method of constant stimuli) procedure would yield comparable …

on each of which are three rows of letters and numbers. When viewed through the
stereoscope one letter or number in each row appears nearer to the eye than the others in …

Measures of commonplace depth discrimination were obtained at observation distances of
200, 750, and 1500 feet in an Arctic area over flat terrain. Comparisons were made with …

The threshold of binocular depth perception was measured in 11 healthy volunteers. A three-
rod arrangement was employed in which both the luminance of the rods and that of the …

Data are presented on binocular depth-discrimination thresholds for stationary and
oscillating black or self-illuminated targets which are presented against a large illuminated …

Two experiments were performed to determine the effects of lateral target separation on
commonplace binocular depth perception and to extend previous studies of the effects of …
