Oliver Sacks – The Man Who Mistook His Wife For A Hat
In The Man Who Mistook His Wife for a Hat and Other Clinical Tales British neuroscientist Oliver Sacks describes the visual agnosia of a patient Dr. P.
Loss of visual perception causes Dr. P cannot wear shoes by himself because he does not know where his shoes are, what his feet are. When Dr. P holding a glove, he would describe it oddly like this: “A continuous plane and foldable, it also has 5 extra bags, if I use the right words”, or he will describe The rose is: “It has a twisted red shape and a green line stuck to the red one.”
Another bad cry or laugh situation is Dr. P mistook his wife for a hat. Oliver Sacks reports in his book that Dr. P looked at his wife’s head into a hat hanging on a rack and kept trying to lift her head from her neck.
