Reading 2: MORE EXPERIENCE = BIGGER BRAIN

56% were left-brain oriented. However, when the same methods were applied to 180 students in various, specialized upper-level courses, the range of left brain students ranged from 38% to 65%. This difference indicated that something about a person's brain hemispheres was associated with spreading students out over a variety of college degrees and interests. Second, and more revealing, Morton employed the same method in determining the hemispheric orientation of members of various professions in university settings. The findings indicated that hemispheric specialization appears to be predictive of professional choices. For example, among biochemists Morton found that 8 3 % were left-brain oriented, while among astronomers only 29% showed a left-brain preference (p. 3 1 9 ) . You can see how this would make sense in relation to Sperry and Gazzaniga's work. Biology and chemistry rely more heavily on linguistic abilities, whereas astronomers must have greater abilities in spatial relationships (no pun intended).
