Aphasia is an impairment of language functioning caused by damaged to the left hemisphere of the brain (Garrett , 2003 ; Hills & Caramazza , 2003 ) . There are different type of aphasic , example ; Boca’s aphasia and Wernicke’s aphasia .
Wernicke’s aphasia is caused by damage to the left temporal lobe of the brain. It is characterized by notable impairment in the understanding of spoken words and sentences . People with Wernicke’s aphasia have generally fluent phonetic and syntactic but semantically Coherent speech .
This coherence is exhibited through the creation of nonsense words for content words ( e.g. noun , verb ) . It also typically involves the production of sentences that have the basic structure of language spoken but that make no sense . They sentences . without any meaning ‘yeah , that was the pumpkin furthest from my thought’ (Hills & Caramazza 2003 ) .
In the first case , the words make sense , but not in the context they are presented . In the second case , the words themselves are neologism , or newly created words. Treatment for patient with his type of aphasia frequencies involves supporting and encouraging non language communication ( Altschuler et al ., 2006 ).
Boca’s aphasia is caused by damage to brain ‘s premotor area , responsible in part , for controlling motor command sused in speech production . A person suffering from Broca ‘s aphasia exhibits speech containing excess pauses and slips of tounge and she has trouble finding words when talking . The person also fails to make use of function words such as a the and of . For this reasons Boca’s aphasics also produce ungrammatical sentence ( Tarter , 1987 ) .
Furthermore they have problem using syntactic information when understanding sentences such as “ the bicycle that the man is holding is blue due to blue trouble comprehending a sentence such as the dog that the women is biting is grey .
