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.
Athelia is the congenital absence of one or both nipples. It is a rare condition. It sometimes occurs on one side in children with the Poland sequence and on both sides in certain types of ectodermal dysplasia. Sources
