Abstract:
Monocular patching might improve perceptual-attentional, not motor-intentional deficits in a patient with chronic post-stroke left spatial neglect. Performing a line-cancellation task, his omission errors were associated with a perceptual-attentional 'where' deficit, while perseverative errors were associated with 'aiming' motor-intentional bias. Contralesional patching had no effect on the omissions (p = .871), whereas ipsilesional patching reduced left-sided omissions compared with the unpatched condition (p = .016). Neither patching condition altered perseverative errors. Further research is needed to examine whether targeting treatments to spatial neglect symptoms (omissions, perseveration) results in improved outcomes.

Perceptual Constancy
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...
