Interocular effects in prism adaptation.

Monocular prism after-effects were measured in three groups of subjects each of whom had walked about wearing a 20-diopter prism, base up, over the right eye and one of the following over the left eye: a diffusing screen, 0-diopter prism, or a 20-diopter prism, base down. The performance of the third group showed that visual-motor spatial coordination in the adult is subject to at least limited interocular independence.
