Answer:
research with these patients has provided evidence for some degree of localization of function of the right and left hemispheres.
Explanation:
The research show that the left hemisphere of our brain play a larger role when we perform analytical tasks. The Right hemisphere of our brain on the other hand play a larger role when we perform creative stark.
Looking on a certain word with partial visual (left or right) only could play a role in which part of brain hemisphere you activate the most. (Even though the influence does not particularly big). There is a good chance that when looking at the word "hammer" like mentioned above, Kareena will put more focus on the function of the words rather than the visual/picture due to the use of her left hemisphere.
