The Dangers of Multitasking?

Like most people, I'm always juggling many tasks at a time. I constantly find myself asking, "should I finish one task at a time or try to accomplish multiple tasks simultaneously (multitask)?" Well, it might just be better to take 'em on one at a time:
Research shows that we consistently perform better and faster when tasks are done successively, rather than all at once.

Good news though, it is not your organized "to-do" list that is to blame. It is your brain:
"We've identified a kind of bottleneck in the prefrontal cortex of the brain that forces people to address problems one after the other, even if they're doing it so fast it feels simultaneous," says René Marois, PhD, associate professor of psychology and neuroscience at Vanderbilt University and coauthor of the study. "This explains why previous data shows brain activity going down instead of up with each new challenge; it's like a mental traffic jam."

So, what can you do to speed up efficiency and get things done? The entire article (courtesy of WebMD) mentions a few things but is not overly helpful. I'll see what advice I can dig up and I'll see if I can find the original research manuscript as well. I always question these fluffy summary pieces... in the meantime, check out David Allen's work on "Getting Things Done (GTD)".
