his experimental study suggests that students who IM while reading will perform as well but take longer to complete the task than those who do not IM while reading or those students who IM before reading.

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. Show More Show Less

That illusion of competence is one of the things that worry scholars who study attention, cognition, and the classroom. Students' minds have been wandering since the dawn of education. But until recently—so the worry goes—students at least knew when they had checked out. A student today who moves his attention rapid-fire from text-messaging to the lecture to Facebook to note-taking and back again may walk away from the class feeling buzzed and alert, with a sense that he has absorbed much more of the lesson than he actually has.

Heavy media users report getting lower grades.  While the study cannot establish a cause and effect relationship between media use and grades, there are differences between heavy and light media users in this regard.  About half (47%) of heavy media users say they usually get fair or poor grades (mostly Cs or lower), compared to about a quarter (23%) of light users.  These differences may or may not be influenced by their media use patterns. (Heavy users are the 21% of young people who consume more than 16 hours of media a day, and light users are the 17% of young people who consume less than 3 hours of media a day.)

"If you're a pilot, you need to be able to monitor multiple instruments at the same time. If you're a cab driver, you need to pay attention to multiple events at the same time. If you're in the military, you need to multi-task too," she said. "On the other hand, if you're trying to solve a complex problem, you need sustained concentration. If you are doing a task that requires deep and sustained thought, multi-tasking is detrimental."
