 "Unlike traditional tutoring services that seek to help students master a subject, brain training purports to enhance comprehension and the ability to analyze and mentally manipulate concepts, images, sounds and instructions. In a word, it seeks to make students smarter...Those results are achieved, the companies say, by repurposing cognitive tasks initially developed by psychologists as tests of mental abilities. With technical names like the antisaccade, the N-back and the complex working memory span task, the exercises are dressed up as games that become increasingly difficult as students gain mastery."
