Comparability of two methods of estimating real-depth acuity.
DM Pierce - … International d'ophtalmologie. International Journal of …, 1975 - europepmc.org
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
estimates of depth acuity using the classic Howard apparatus. The findings were that:(1)
thresholds derived from the two procedures were not significantly correlated under either
binocular or monocular viewing conditions;(2) essentially equivalent thresholds were
derived from the two procedures under the binocular viewing condition;(3) thresholds …
