For example, in the seven or so seconds, on average, that it took students in the study to solve a logical reasoning problem, researchers recorded at least 23 eye movements. Among other clues, ocular activity indicated which data students absorbed, or disregarded, to arrive at their conclusions. The study builds on previous findings by Bunge and fellow researchers that track cognitive changes in students during mentally challenging learning tasks. For example, a 2012 study found that a three-month LSAT course strengthened the circuitry in the brain's frontoparietal network and boosted the reasoning skills of two dozen young adults, compared to pre-law students who did not complete the course. - www.sciencedaily.com
