Despite all our highly publicized efforts to improve our schools, the United States is still falling behind. We recently ranked 15th in the world in reading, math, and science. Clearly, more needs to be done. In The Learning Brain, Torkel Klingberg urges us to use the insights of neuroscience to improve the education of our children. The key to improving education lies in understanding how the brain works: that is where learning takes place, after all. The book focuses in particular on "working memory"--our ability to concentrate and to keep relevant information in our head while ignoring distractions (a topic the author covered in The Overflowing Brain). Research shows enormous variation in working memory among children, with some ten-year-olds performing at the level of a fourteen-year old, others at that of a six-year old. More important, children with high working memory have better math and reading skills, while children with poor working memory consistently underperform. Interestingly, teachers tend to perceive children with poor working memory as dreamy or unfocused, not recognizing that these children have a memory problem. But what can we do for these children? For one, we can train working memory. The Learning Brain provides a variety of different techniques and scientific insights that may just teach us how to improve our children's working memory. Klingberg also discusses how stress can impair working memory (skydivers tested just before a jump showed a 30% drop in working memory) and how aerobic exercise can actually modify the brain's nerve cells and improve classroom performance. Torkel Klingberg is one of the world's leading cognitive neuroscientists, but in this book he wears his erudition lightly, writing with simplicity and good humor as he shows us how to give our children the best chance to learn and grow.

As the pace of technological change accelerates, we are increasingly experiencing a state of information overload. Statistics show that we are interrupted every three minutes during the course of the work day. Multitasking between email, cell-phone, text messages, and four or five websites while listening to an iPod forces the brain to process more and more informaton at greater and greater speeds. And yet the human brain has hardly changed in the last 40,000 years.
Are all these high-tech advances overtaxing our Stone Age brains or is the constant flood of information good for us, giving our brains the daily exercise they seem to crave? In The Overflowing Brain, cognitive scientist Torkel Klingberg takes us on a journey into the limits and possibilities of the brain. He suggests that we should acknowledge and embrace our desire for information and mental challenges, but try to find a balance between demand and capacity. Klingberg explores the cognitive demands, or "complexity," of everyday life and how the brain tries to meet them. He identifies different types of attention, such as stimulus-driven and controlled attention, but focuses chiefly on "working memory," our capacity to keep information in mind for short periods of time. Dr Klingberg asserts that working memory capacity, long thought to be static and hardwired in the brain, can be improved by training, and that the increasing demands on working memory may actually have a constructive effect: as demands on the human brain increase, so does its capacity.
The book ends with a discussion of the future of brain development and how we can best handle information overload in our everyday lives. Klingberg suggests how we might find a balance between demand and capacity and move from feeling overwhelmed to deeply engaged.
