Brain Lateralization and Language Reflection
In this reflection paper the author defines brain lateralization as a complex and ongoing process by differing regions of the brain which control specific behaviors and cognitive skills. It will also cover what happens to language when the brain experiences a trauma or damage.
Brain lateralization is a very complex process in which different regions of one’s brain to take over the functioning of specific behaviors and cognitive skills. Lateralization means that certain functions are located (in part or whole) on one side of the brain. According to fMRI data and other methods, the
left hemisphere is dominant for speech production in more than 95% of right-handers and nearly 80% of left handers (Kalat, 2013).
Functions that are related to the left side of the brain include the ability of understanding and usage of language (listening, reading, speaking and writing), memory for spoken and written word, detailed information analysis as well as motor control of the right side of the body. Functions that are regulated to one’s right side of their brain include judging the position of objects in space, understanding body position, understanding and remembering things you do or see, piecing together information to form a complete picture and motor control of the left side of the body.
A delay in lateralization can effect cognitive and behavioral skills. Brain lateralization is essential to appropriate language and social skills development. In 1861, a French surgeon, Paul Broca discovered that damage to the left hemisphere resulted in aphasia (language impairment) (Kalat, 2013). In nearly all the cases the patient suffered damage to the Broca’s area. This was usually the result of a stroke (interruption of blood flow to part of the brain). Damage that is limited to the Brocas area results in minor or brief language impairment.
This type of damage is called Broca’s Aphasia regardless of the location of the damage. People who suffer from aphasia have comprehension deficits when the meaning of a sentence requires prepositions, word endings or unusual word order or basically when sentence structure is complicated.
In conclusion, this paper has covered brain lateralization and discussed how trauma to the brain effects language.
