Smelly Knowledge

With a toddler, a half-time job with full-time responsibilities, a dad-ship, a husband-ship, a strong sense of civic duty and right-and-wrong, and a desire to keep up with this blog thing, I often feel myself being pulled in multiple directions at once. The end result is that basically nothing gets done or done all that well, feeding a sense of anxiety. As I have written earlier, a large part of this feeling can be attributed to a, as Thomas Hylland Eriksen puts it, “lack of freedom from information.” This “lack of freedom,” and the need to make sense and meaning of it all, does play nicely into the notion of connectivism, and the need to look for breadth rather than depth. But am I the only one who feels like I’m unable to keep my head above water?

Apparently, I’m not. I found this wonderful podcast, The Myth of Multi-Tasking. Merlin Mann of 43Folders posits that when one says they are multitasking, they are really just slicing their attention into smaller and smaller chunks. It is well worth listening to the podcast (it is on the short side), he talks about the self-perceived ability to multitask:

We’ve really been habituated over the years to thinking of ourselves, we should basically be these parallel processing computers and our conscience mind should be able to be in ten places at once….

There is alot of pressure to “multitask.” I’ve even been described by a former supervisor as a good multitasker. But I still feel quite overwhelmed, so Merlin’s podcast really speaks to me.

So is there any scientific basis behind Merlin’s astute observations? As a matter of fact, there is. I did a little digging and found the report Functional Magnetic Resonance Imaging Provides New Constraints on Theories of the Psychological Refractory Period associated with an American Psychological Society’s press release entitled We Weren’t Made to Multitask. It turns out that Merlin’s observations are actually validated by fMRI studies; as a person moves back-and-forth between tasks in a “multitasking” environment, they are “passive-queuing” the unfocused tasks rather than “active-monitoring.” The authors further discovered,

…no increase in the sort of activity that would be involved in keeping two thought processes separate when subjects had to switch faster. This suggests that there are no complicated mechanisms that allow people to perform two tasks at once. Instead, we have to perform the next task only after the last one is finished.

Could it be that even slicing our attention into tiny little slices could be detrimental to the task at hand? Likely, as the more we switch, the more we passively queue — rather than actively — engage with the task. This, I believe, has an impact as to how we approach learning and teaching, as we look for ways to encourage active learning.

But for us as people, Merlin gently reminds us,

…once you realize you can only ever do one thing at a time, an amazing thing happens. You discover that all this anxiety that has been acting as a spackle in your brain to turn all of your tasks into one ginormous task, the anxiety goes away. Suddenly, the tasks break down back into the single activities that they really are. And your brain spends more time on creative efforts instead of generating more anxiety for that monster in your head. And that can be really powerful.
