  Purpose

The ability to maintain balance and avoid falling is highly dependent on the ability to locate objects and architectural features in the environment. This need to continually monitor the environment as one moves about in daily life suggests a critical role for visual attention, gaze control, and spatial memory, all of which are known to decline with aging. In this study, the investigators will test the efficacy of a computer-based visual-training program designed to improve the ability to rapidly extract information from the peripheral visual field. It is expected that older adults involved in the visual training intervention will improve the speed, accuracy, and effectiveness of reach-to-grasp balance-recovery reactions evoked by sudden unpredictable balance perturbation.
