I remember when I was younger, I used to challenge myself to see how much I could multitask at once, and I was so proud of it. Looking back, I realize the immense pressure I put on my nervous system. I believe many of us who feel the need to do it all often judge ourselves harshly when we perceive ourselves falling short of the goal of not just completing tasks but excelling at them. These days, we are more aware that being present and cultivating mindfulness is a healthier and wiser choice.
My current challenge is to understand the origin of this belief and work on unraveling it one day at a time. To discover contentment in this ongoing journey (which is no easy feat) and to acknowledge that we never truly 'get it done,' as humans are all a work in progress. I'm constantly in awe of the miracles of nature and turn to metaphysics to help maintain my balance.
Earl Miller, a neuroscientist at MIT and one of the world experts on divided attention, says that our brains are “not wired to multitask well… When people think they’re multitasking, they’re actually just switching from one task to another very rapidly. And every time they do, there’s a cognitive cost in doing so.” So we’re not actually keeping a lot of balls in the air like an expert juggler; we’re more like a bad amateur plate spinner, frantically switching from one task to another, ignoring the one that is not right in front of us but worried it will come crashing down any minute. Even though we think we’re getting a lot done, ironically, multitasking makes us demonstrably less efficient.
Neuroscientist Danial J. Levitin “Multitasking has been found to increase the production of the stress hormone cortisol as well as the fight-or-flight hormone adrenaline, which can overstimulate your brain and cause mental fog or scrambled thinking. Multitasking creates a dopamine-addiction feedback loop, effectively rewarding the brain for losing focus and for constantly searching for external stimulation. To make matters worse, the prefrontal cortex has a novelty bias, meaning that its attention can be easily hijacked by something new – the proverbial shiny objects we use to entice infants, puppies, and kittens. The irony here for those of us who are trying to focus amid competing activities is clear: the very brain region we need to rely on for staying on task is easily distracted. We answer the phone, look up something on the internet, check our email, send an SMS, and each of these things tweaks the novelty-seeking, reward-seeking centers of the brain, causing a burst of endogenous opioids (no wonder it feels so good!), all to the detriment of our staying on task. It is the ultimate empty-caloried brain candy. Instead of reaping the big rewards that come from sustained, focused effort, we instead reap empty rewards from completing a thousand little sugar-coated tasks.
