Comparability of two methods of estimating real-depth acuity.
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 derived from the verbal procedure were significantly higher than those derived from the motor adjustment procedure under monocular viewing conditions.
