Individuals with prosopagnosia may differ in their abilities to understand faces, and it has been the investigation of these differences which has suggested ...
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 difficulty with spatial layout of an ...
