Maybe Professor Kingsfield was on to something. Karen Sloan reports in NLJ:
Few law students look back fondly on taking the Law School Admission Test, but those who spend a lot of time studying for it may see benefits beyond higher scores.
Researchers at the University of California, Berkeley Department of Psychology and U.C.'s Helen Wills Neuroscience Institute have found that intensive LSAT study alters the brain, reinforcing circuits and helping bridge the gap between its right and left hemispheres.
"The fact that performance on the LSAT can be improved with practice is not new," said graduate student Allyson Mackey, the lead researcher. "What we were interested in is whether and how the brain changes as a result of LSAT preparation -- which we think is, fundamentally, reasoning training. We wanted to show that the ability to reason is malleable in adults."
