There's another fascinating book out about the way our brains work. A delightful woman named Winifred Gallagher has just published Rapt--Attention and the Focused Life. Using some pretty impressive research, she makes another case to support something I learned in the excellent book Brain Rules: that multitasking just doesn't work. Period.
A scientific study shows, according to Rapt, that our optimum period of concentration is ninety minutes. That means ninety minutes without phone interruptions, email distractions, conversations. Then, the study tells us, we should get up, move around, do something else. It also tells us that every interruption means the brain has to waste a significant amount of time getting "back on track". This seems to me a perfect model for a writer! I hope that's not just because I'm such a physically restless person.
Here's the blurb from the Penguin USA website:
In Rapt, acclaimed behavioral science writer Winifred Gallagher makes the radical argument that the quality of your life largely depends on what you choose to pay attention to and how you choose to do it. Gallagher grapples with provocative questions—Can we train our focus? What’s different about the way creative people pay attention? Why do we often zero in on the wrong factors when making big decisions, like where to move?—driving us to reconsider what we think we know about attention.
Gallagher looks beyond sound bites on our proliferating BlackBerries and the increased incidence of ADD in children to the discoveries of neuroscience and psychology and the wisdom of home truths, profoundly altering and expanding the contemporary conversation on attention and its power. Science’s major contribution to the study of attention has been the discovery that its basic mechanism is an either/or process of selection. That we focus may be a biological necessity— research now proves we can process only a little information at a time, or about 173 billion bits over an average life—but the good news is that we have much more control over our focus than we think, which gives us a remarkable yet underappreciated capacity to influence our experience. As suggested by the expression “pay attention,” this cognitive currency is a finite resource that we must learn to spend wisely. In Rapt, Gallagher introduces us to a diverse cast of characters—artists and ranchers, birders and scientists—who have learned to do just that and whose stories are profound lessons in the art of living the interested life. No matter what your quotient of wealth, looks, brains, or fame, increasing your satisfaction means focusing more on what really interests you and less on what doesn’t. In asserting its groundbreaking thesis—the wise investment of your attention is the single most important thing you can do to improve your well-being—Rapt yields fresh insights into the nature of reality and what it means to be fully alive.
