Effects of Perceptual-motor Training on Collision Judgments with Peripheral Prism Expanded Vision.

ABSTRACT:

Significance

Peripheral prisms (p-prisms) improve blind-side detection of hazards in hemianopia by shifting the image of the hazard into the intact visual field. Collision judgments can be made accurately after detection by using a gaze shift to fixate the hazard in the prism-free portion of the lens, but this is slow relative to normal peripheral vision. A prior study found that prism adaptation for visual direction did not occur with general wear. We developed a perceptual-motor training regimen that resulted in accurate pointing at p-prism targets after six 1-hour sessions.

Purpose

This study aimed to determine if improvements in pointing accuracy from perceptual-motor training generalized to collision judgments during simulated walking.
