Are Left-Handers Brains More Efficient?
Monday morning, while riding to a deposition, I was listening to ESPN on the radio, and the commentators were discussing the question of whether left-handed people were smarter than right-handed people. This "sports" discussion highlighted an interesting article I read in the New Zealand Herald on Saturday. The article reported on a recent study published in the journal Neuropsychology by Australian researchers that found that left-handers were more efficient when dealing with multiple stimuli as a result of faster transformation of information in the brain. Quoting Dr. Nick Cherbuin, "These findings confirm our prediction of increasing efficiency of hemispheric interactions with increasing left-handedness." According to the article, between eight and fifteen percent population are left-handed with identical twins more likely to be so than the rest of the population.
