Not all functions of the hemispheres are shared. In general, the left hemisphere controls speech, comprehension, arithmetic, and writing. The right hemisphere controls creativity, spatial ability, artistic, and musical skills. The left hemisphere is dominant in hand use and language in about 92% of people.
The left part of the temporal lobe, for example, helps children acquire language. It makes the correlation between sounds heard and things seen or otherwise experienced. The left brain seems to be what side of the brain controls speech in 96% of children. There are creative areas in the brain that put concepts and experiences in different orders to think up new ways to say things. What side of the brain controls speech is not so obvious in this case. Creative thinking is generally thought to be in the right side of the brain, but not in this case. Oral language is spoken first in the mind. This happens especially when you rehearse a speech, or think in words about something.
