The Use Of Hemifield Eye-Patching For Modifying The Perceptual-Attentional Bias In Healthy Individuals, Randall L. Miller

Seton Hall University Dissertations and Theses (ETDs)

Healthy individuals do not perceive the left and right sides of space equally, showing a leftward spatial bias on visuospatial tasks. This bias may be more attributed to a perceptual-attentional (PA) component than a motor-intentional (MI) component. While monocular eye patching alters this spatial bias via modification of PA but not MI, hemifield eye patches that occluded the left or right half of the visual field have been shown to be more effective at modifying spatial bias, but only in patients with spatial neglect. Furthermore, it is unclear whether hemifield patching affects PA, MI, or both. The goal of the …
