a "fencer's mask". A dart was a "feather duster" and a protractor was mistaken for a "cockpit". Despite this impairment in visual object recognition, C.K. retained many abilities such as drawing, visual imagery, and internal imagery. As a native of England, he was tasked with drawing England, marking London and where he was born. His accurate drawing of England is just one example of his excellent drawing abilities. As aforementioned, C.K. is able to identify parts of objects but cannot generate a whole representation. It should not be surprising then that his visual imagery for object size, shape, and color is intact. For example, when shown a picture of an animal, he can correctly answer questions such as "are the ears up or down?" and "is the tail long or short?" He can correctly identify colors, for example that the inside of a cantaloupe is orange. Finally, C.K. can generate internal images and perceive these generated objects. For example, Finke, Pinker, and Farah instructed C.K. to imagine a scenario where a 'B' is rotated 90 degrees to the left, a triangle is put below, and the line in the middle is removed. C.K. can correctly identify this object as a heart by picturing this transformation in his head. Evidence for double dissociation between face and object processing Patient C.K. provided evidence for a double dissociation between face processing and visual object processing. Patients with prosopagnosia have damage to the Fusiform Face Area (FFA) and are unable to recognize upright faces. C.K. has no difficulty with face processing and matches the performance of controls when tasked with identifying upright famous faces. When shown inverted faces of famous people, C.K. performs significantly worse than controls. This is because processing inverted faces involves a piecemeal strategy. C.K.'s performance is compared to patients with prosopagnosia who are impaired in face processing but perform well identifying inverted faces. This was the first evidence for a double dissociation between face and object processing suggesting a face-specific processing system. In popular culture A famous report on this condition is the title essay of Oliver Sacks' book, The Man Who Mistook His Wife for a Hat. The murder suspect in the Picket Fences episode "Strangers" supposedly had agnosia. The patient in the House episode "Adverse Events" had agnosia. In the graphic novel Preacher, the character Lorie has an extreme version of agnosia resulting from being born with a
