What is the difference between aphasia vs. agnosia? What are some examples of each?<\/p>\n\n\n\n

In his book The Man Who Mistook His Wife for a Hat<\/a>, <\/em>Oliver Sacks examines multiple cases of aphasia and agnosia. He describes the behaviors of patients with each condition and explains the differences between the two. <\/p>\n\n\n\n

Here are Oliver Sacks’ case studies and an explanation of the difference between aphasia vs. agnosia. <\/p>\n\n\n\n\n\n\n\n

Reagan\u2019s Speech and the Aphasiacs<\/strong><\/h2>\n\n\n\n

Oliver Sacks’ case studies of aphasia vs. agnosia begin with a study of aphasiacs. Neurologists often speak of brain disorders in terms of deficits. A deficit is some impairment of neurological function, usually linked to brain damage to some particular area. Damage to Broca\u2019s area, for example, is known to cause aphasia.<\/p>\n\n\n\n

The ability to understand language is one of the defining traits of humanity. Other organisms communicate through sounds, but there is no parallel to the evocative power of human speech. Yet some people who\u2019ve suffered brain damage are robbed of this ability. They suffer from aphasia\u2014the inability to process and understand spoken words. <\/strong><\/p>\n\n\n\n

But, as we\u2019ve seen, the brain has a remarkable ability to compensate for deficits in one area with neurological surpluses in another. Aphasiacs may possess an uncanny ability to look beyond the veil of words and derive true meaning more clearly than anyone. <\/p>\n\n\n\n

Aphasia: Seeing Past the Words<\/strong><\/h3>\n\n\n\n

In the 1980s, Sacks was at an aphasiac ward of a psychiatric hospital, where the patients were watching a televised speech being given by President Ronald Reagan. Their aphasia inhibited them from processing and understanding the words the president was speaking. But they could still understand the <\/strong>non-verbal<\/em><\/strong> aspects of language<\/strong>, indeed, far better than most other people. Sacks observed that they were highly attuned to the changing rhythms, intonations, and cadences of Reagan\u2019s speech.<\/p>\n\n\n\n

Looking past the words prepared by Reagan\u2019s speechwriters, they heard only his tone and inflection. Based upon this, they saw the polished actor-turned-president as a dissembling phony, keenly picking up on the falseness of his tone and body language<\/a><\/strong>. And their reaction to his speech was not reverential respect\u2014it was uproarious, hysterical laughter! Sacks learned that one cannot fool an aphasiac with slick rhetoric, because they have extra heightened sensitivity to tone and can never be misled with words.<\/p>\n\n\n\n

Agnosia: Just the Words<\/strong><\/h3>\n\n\n\n

Agnosia presents the exact opposite condition. Someone with agnosia can understand <\/strong>only <\/em><\/strong>words, but not tone or expression<\/strong>. Sacks asked an agnosia patient named Emily D. how she <\/em>interpreted Reagan\u2019s address. Because she could understand nothing but <\/em>words, Emily needed people to use precise wording in order for her to derive meaning from speech. Slang, colloquialisms, metaphors, or any other imprecisions of language would render what she was hearing incomprehensible.<\/p>\n\n\n\n

When she listened to Reagan\u2019s speech, she focused on its imprecision with words. The president was not clear in what he meant, and, according to Emily, this meant he was either brain-damaged or being dishonest. Once again, it took patients with brain damage to look past Reagan\u2019s slick speech and see it for what it really was. <\/p>\n","protected":false},"excerpt":{"rendered":"
