Perception of Straight Ahead With Vision, Hearing, and Proprioception by Individuals With Low Vision.

ABSTRACT:

Purpose

The perception of straight ahead (PSA) is an important reference for spatial orientation. Although individuals with low vision often report difficulties in spatial tasks, it is not clear whether they face challenges in defining PSA. We asked whether low vision leads to increased biases and variabilities in visual PSA, and whether these changes, if any, would generalize to auditory PSA, due to the dominant role of vision in spatial tasks.

Methods

Thirty-five low-vision participants and 17 age-matched control participants completed visual and auditory PSA tasks in which they adjusted the location of a brief LED light or a finger snap sound from a speaker to appear to be straight ahead. To control for proprioception, participants also completed a PSA task in which they
