Psychophysical scaling of the prism diopter unit
Tóm tắt
The relation between actual and perceived prism displacement was investigated for monocular and haploscopic conditions. Five subjects made estimates of the displacement of 10 prisms ranging in power from.76 to 21.03 prism diopters. The power exponent for both monocular and haploscopic conditions approximated unity. The demonstration that perceived prism displacement is a ratio scale will allow the treatment of tests of monocular and haploscopic prism displacement by parametric statistics.
