Meet the Life Hackers examines our modern, multi-tasking work environment:
A computer screen offers very little visual real estate. It is like working at a desk so small that you can look at only a single sheet of paper at a time. A Microsoft Word document can cover almost an entire screen. Once you begin multitasking, a computer desktop very quickly becomes buried in detritus.This is part of the reason that, when someone is interrupted, it takes 25 minutes to cycle back to the original task. Once their work becomes buried beneath a screenful of interruptions, office workers appear to literally forget what task they were originally pursuing. We do not like to think we are this flighty: we might expect that if we are, say, busily filling out some forms and are suddenly distracted by a phone call, we would quickly return to finish the job. But we don’t. Researchers find that 40 percent of the time, workers wander off in a new direction when an interruption ends, distracted by the technological equivalent of shiny objects. The central danger of interruptions, Czerwinski realized, is not really the interruption at all. It is the havoc they wreak with our short-term memory: What the heck was I just doing?

The researchers took 15 volunteers, sat each one in front of a regular-size 15-inch monitor and had them complete a variety of tasks designed to challenge their powers of concentration — like a Web search, some cutting and pasting and memorizing a seven-digit phone number. Then the volunteers repeated these same tasks, this time using a computer with a massive 42-inch screen, as big as a plasma TV.The results? On the bigger screen, people completed the tasks at least 10 percent more quickly — and some as much as 44 percent more quickly. They were also more likely to remember the seven-digit number, which showed that the multitasking was clearly less taxing on their brains. Some of the volunteers were so enthralled with the huge screen that they begged to take it home. In two decades of research, Czerwinski had never seen a single tweak to a computer system so significantly improve a user’s productivity.
