Question

Quizplus · Accepted Answer

Mr. Altschuler's ability to avoid bumping into furniture and tripping over items on the floor suggests that he has blindsight, a condition in which a person is unable to consciously see objects but can still use visual information to guide their movements. The fact that he sees no objects suggests that he may have visual agnosia, but without more information it is difficult to say definitively. A thalamic lesion or severed corpus callosum would likely have other symptoms beyond just the inability to consciously perceive objects.
