Worksheet B 1. I am a right-handed person.Most persons prefer their right hand generally because the left hemisphere dominates the right hemisphere.The result of such dominance is that people with left hemisphere dominant would tend to prefer the right side of the body.

5. Theoretically, left handed people suppose to be right hemisphere dominant because as we know, those two hemispheres control the opposite side of the body. But, according to a study, majority of left-handers are left hemisphere dominant. This means left handers use the same left hemisphere as the right handers, but their dominance is weaker than the right handers'. This lack of strong dominance contributes to various reading and writing dysfunctions. They are also having these dysfunctions (more to reading dysfuntion) because the two hemispheres are competing with one another for dominance.

6. When the connection between the hemispheres is cut, information no longer flowed from hemisphere to hemisphere as it does in normal persons. The functions of the complete brain were no longer integrated.

Although ‘split-brain’ person could still use speech and writing in the disconnect left hemisphere but their right hemisphere had little capacity compare to the normal person.

Touch information-> left hemisphere = the ‘split-brain’ person will completely able to describe objects and talk about things they had just touched.

Touch information-> right hemisphere = the ‘split-brain’ person could not talk about the experience at all. = information could not be passed through the corpus callosum to the left hemisphere for expression in speech because the corpus callosum had been cut.

This related to lateralization because every hemisphere has different functions. This separation of function is called lateralization.

7. Wernike’s Aphasia
