The Verhoeff Test of Depth Perception was administered on each of two occasions to 100 patients and volunteers at the Eye Clinic of the U. S. Naval School of Aviation Medicine. On each occasion two forms of the test were used the standard instrument held in the hand of the tester, and a modified apparatus mounted in a rigid framework. Test-retest reliability of the standard form was 0.75 and of the modified form 0.80. Neither form showed a marked superiority over the other. Author
