EFFECT OF TRAINING ON STEREOSCOPIC ACUITY

The ability to train stereoscopic acuity has not been tested. Indirect evidence arising as a byproduct of other studies has been inconclusive. The purpose of this study was to determine if stereoscopic acuity could, in fact, be improved by training. A group of 16 subjects was measured with stereometric cards in a telebinocular and divided into a control and an experimental section. The latter underwent training in an instrument in which they repeatedly adjusted one virtual object to lie in the same fronto-parallel plane as another virtual object. Post training retest showed both groups to have improved performance. The experimental section demonstrated far greater improvement, a difference statistically significant at the 0.01 level, indicating that stereoscopic acuity had been improved by training.
