The Myth of Multitasking
Ever wondered why other people seem to master multitasking whilst you struggle to manage more than one task at a time? If you’re envious of the seven-second attention span of a goldfish, ‘Flow’ is now you. Worry no more. Multitasking is and has always been, urban myth.
The truth is out. After decades of articles opining the benefits of multitasking, all of the ‘how to’s’ ‘Made simples’ and ‘Guides’ -we now know that the ability to focus on several tasks at the same time isn’t neurologically possible. So when you’re checking your phone whilst talking, reading the paper whilst watching TV or driving and making a call using hands free, you’re not completely focused.
Research by Gloria Mark, Professor of Informatics at the University of California found that when we’re continually distracted we may work faster but we produce less. That would explain the plethora of mistakes we typically tend to make when we’re not completely focused on the task at hand.
Dr JoAnn Deak author of ‘Your Fantastic Elastic Brain” states that “When you try to multitask, in the short term it doubles the amount of time it takes to do a task and it usually at least double the number of mistakes.” Worse still, researchers at Stanford University found that regular multitaskers are particularly bad at it, suggesting that serial multitaskers are easily distracted. Known as ‘switchtasking’ quickly jumping from one task to another, leaving a slew of mistakes in its’ wake. Rather than making us more efficient, switchtasking makes us less accurate and slows us down. The problem is, we’re so convinced that it’s possible, we just don’t notice our performance has suffered due to our lack of focus.
Switchtasking can also elevate our stress levels, ramping up the pressure, feeding into the feeling that there’s too much to do and not enough time to do it in. Research by René Marois at Vanderbilt University, using fMRI found that the brain responds to multiple tasks with a “response selection bottleneck” slowing us down as it attempts to prioritise tasks. Little wonder then, that multitasking impacts our learning and leaves us feeling even more fatigued, contributing to the release of stress hormone nasties like cortisol and adrenaline. Left unchecked, the long-term effects upon our health can be catastrophic.
It’s all thanks to the default mode network (DMN) a cluster of brain areas that become active when we’re not actively focusing on a specific task. It’s just the way that we’re wired.
David Rock, author of Your Brain at Work says, “A distraction is an alert. It says, orient your attention here now; this could be dangerous.” The digital world that we now live in offers a multitude of distractions “It reduces our intelligence, literally dropping our IQ. We make mistakes, miss subtle cues, fly off the handle when we shouldn’t, or spell things wrong.” To add insult to injury, multitasking makes us less intelligent than we might otherwise be.
During a Harvard study examining mind wandering by Matthew Killingsworth and Daniel Gilbert 2,000 adults were tested throughout the day. Killingsworth and Gilbert found they were distracted for a whopping 47 percent of the time. What’s more they were less happy as a result, typically experiencing stressful thoughts or negative rumination. All excellent reasons to ditch switchtasking.
So if multitasking is dead, how do we focus? The good news is your brain is a muscle, just like any other muscle in your body. The trick is to train it. Flow is a state of optimum performance and you can train yourself to achieve it. Here’s how.
