Document Summary
Aphasia: difficulty in producing or comprehending speech not produced by deafness or a simple motor deficit; caused by brain damage. Most language disturbances occur after damage to the left side of the brain, whether people are left-handed or right-handed. Right hemisphere= critical in reading maps, perceive spatial relationships, recognizing complex geometrical forms. Also controls emotion in the tone of voice and organizes a narrative selecting and assembling the elements of what we want to say. The cerebral hemispheres (the occipital, temporal, and parietal lobes) are largely responsible for our having something to say. The conversion of perceptions, memories, and thoughts into speech makes use of neural mechanisms located in the frontal lobes. People with broca"s aphasia rarely use function words or grammatical markers such as ed or auxiliaries such as have. The comprehension of people with broca"s aphasia is not normal.
