visual agnosia उदाहरण वाक्य

The dissociation between visual agnosia and optic ataxia has been challenged by several researchers as not as strong as originally portrayed; Hesse and colleagues demonstrated dorsal stream impairments in patient DF; Himmelbach and colleagues reassessed DF's abilities and applied more rigorous statistical analysis demonstrating that the dissociation wasn't as strong as first thought.
This suggests that perceptual awareness is modular and that in sighted individuals there is a " binding process that unifies all information into a whole percept ", which is interrupted in patients with such conditions as blindsight and visual agnosia . motion, and low spatial frequency contribute to, but are not strictly necessary for, an object's salience in blindsight.
These variants of visual agnosia include prosopagnosia ( inability to recognize faces ), pure word blindness ( inability to recognize words, often called " agnosic alexia " or " pure alexia " ), agnosias for colors ( inability to differentiate colors ), agnosias for the environment ( inability to recognize landmarks or difficult with spatial layout of an environment, i . e . topographagnosia ) and simultanagosia ( inability to sort out multiple objects in a visual scene ).
