This article is a tad long, I'm attempting to show the best parts. [quote]In the late 1990s and early 2000s, one sensed a kind of exuberance about the possibilities of multitasking. Advertisements for new electronic gadgets — particularly the first generation of handheld digital devices — celebrated the notion of using technology to accomplish several things at once. The word multitasking began appearing in the “skills” sections of résumés, as office workers restyled themselves as high-tech, high-performing team players. “We have always multitasked — inability to walk and chew gum is a time-honored cause for derision — but never so intensely or self-consciously as now,” James Gleick wrote in his 1999 book Faster. “We are multitasking connoisseurs — experts in crowding, pressing, packing, and overlapping distinct activities in our all-too-finite moments.” An article in the New York Times Magazine in 2001 asked, “Who can remember life before multitasking? These days we all do it.” The article offered advice on “How to Multitask” with suggestions about giving your brain’s “multitasking hot spot” an appropriate workout.[/quote] Section 2 [quote]To better understand the multitasking phenomenon, neurologists and psychologists have studied the workings of the brain. In 1999, Jordan Grafman, chief of cognitive neuroscience at the National Institute of Neurological Disorders and Stroke (part of the National Institutes of Health), used functional magnetic resonance imaging (fMRI) scans to determine that when people engage in “task-switching” — that is, multitasking behavior — the flow of blood increases to a region of the frontal cortex called Brodmann area 10. (The flow of blood to particular regions of the brain is taken as a proxy indication of activity in those regions.) “This is presumably the last part of the brain to evolve, the most mysterious and exciting part,” Grafman told the New York Times in 2001 — adding, with a touch of hyperbole, “It’s what makes us most human.” It is also what makes multitasking a poor long-term strategy for learning. Other studies, such as those performed by psychologist René Marois of Vanderbilt University, have used fMRI to demonstrate the brain’s response to handling multiple tasks. Marois found evidence of a “response selection bottleneck” that occurs when the brain is forced to respond to several stimuli at once. As a result, task-switching leads to time lost as the brain determines which task to perform. Psychologist David Meyer at the University of Michigan believes that rather than a bottleneck in the brain, a process of “adaptive executive control” takes place, which “schedules task processes appropriately to obey instructions about their relative priorities and serial order,” as he described to the New Scientist. Unlike many other researchers who study multitasking, Meyer is optimistic that, with training, the brain can learn to task-switch more effectively, and there is some evidence that certain simple tasks are amenable to such practice. But his research has also found that multitasking contributes to the release of stress hormones and adrenaline, which can cause long-term health problems if not controlled, and contributes to the loss of short-term memory.[/quote] Section 3 [quote]When we talk about multitasking, we are really talking about attention: the art of paying attention, the ability to shift our attention, and, more broadly, to exercise judgment about what objects are worthy of our attention. People who have achieved great things often credit for their success a finely honed skill for paying attention. When asked about his particular genius, Isaac Newton responded that if he had made any discoveries, it was “owing more to patient attention than to any other talent.” William James, the great psychologist, wrote at length about the varieties of human attention. In The Principles of Psychology (1890), he outlined the differences among “sensorial attention,” “intellectual attention,” “passive attention,” and the like, and noted the “gray chaotic indiscriminateness” of the minds of people who were incapable of paying attention. James compared our stream of thought to a river, and his observations presaged the cognitive “bottlenecks” described later by neurologists: “On the whole easy simple flowing predominates in it, the drift of things is with the pull of gravity, and effortless attention is the rule,” he wrote. “But at intervals an obstruction, a set-back, a log-jam occurs, stops the current, creates an eddy, and makes things temporarily move the other way.” To James, steady attention was thus the default condition of a mature mind, an ordinary state undone only by perturbation. To readers a century later, that placid portrayal may seem alien — as though depicting a bygone world. Instead, today’s multitasking adult may find something more familiar in James’s description of the youthful mind: an “extreme mobility of the attention” that “makes the child seem to belong less to himself than to every object which happens to catch his notice.” For some people, James noted, this challenge is never overcome; such people only get their work done “in the interstices of their mind-wandering.” Like Chesterfield, James believed that the transition from youthful distraction to mature attention was in large part the result of personal mastery and discipline — and so was illustrative of character. “The faculty of voluntarily bringing back a wandering attention, over and over again,” he wrote, “is the very root of judgment, character, and will.”[/quote] [i]Personally I find that multi-tasking is a process that can be done sometimes, and with some things. Not all tasks can be properly multi-tasked as is evidenced by car crashes when someone attempts to make a phone call or text, and many other situations. Though most would find it to be wholly impossible. My High School Psychology teacher said this as well, and we watched several documentaries and studied the "art of multi-tasking" a decent amount. And even though I respect the man and realize his intelligence, I still think it's wrong to say that you cannot multi-task at all, it entirely depends on what you're doing as you try to jumble more than one thing at once.[/i] Thoughts?
