How to Focus A Wandering Mind

New
research reveals what happens in a wandering mind—and sheds light on the
cognitive and emotional benefits of increased focus.
We’ve
all been there. You’re slouched in a meeting or a classroom, supposedly paying
attention, but your mind has long since wandered off, churning out lists of all
the things you need to do—or that you could be doing if only you weren’t stuck
here…
Suddenly
you realize everyone is looking your way expectantly, waiting for an answer. But
you’re staring blankly, grasping at straws to make a semi-coherent response. The
curse of the wandering mind!
But
don’t worry—you’re not alone. In fact, a recent
study by Matthew Killingsworth and Daniel Gilbert sampled over 2,000 adults
during their day-to-day activities and found that 47 percent of the time, their
minds were not focused on what they were currently doing. Even more striking,
when people’s minds were wandering, they reported being less happy.
This
suggests it might be good to find ways to reduce these mental distractions and
improve our ability to focus. Ironically, mind-wandering itself can help
strengthen our ability to focus, if leveraged properly. This can be achieved
using an age-old skill: meditation. Indeed, a new wave of research reveals what
happens in our brains when our minds wander—and sheds light on the host of
cognitive and emotional benefits that come with increased focus.
What
happens in the wandering mind?
For
something that happens so often, what do we really know about this process of
mind-wandering?
For
thousands of years, contemplative practices such as meditation have provided a
means to look inward and investigate our mental processes. It may seem
surprising, but mind-wandering is actually a central element of focused
attention (FA) meditation. In this foundational style of meditation, the
practitioner is instructed to keep her attention on a single object, often the
physical sensations of breathing.
Sounds
simple enough, but it’s much easier said than done. Try it for a few minutes and
see what happens.
If
you’re like most people, before long your attention will wander away into
rumination, fantasy, analyzing, planning. At some point, you might realize that
your mind is no longer focused on the breath. With this awareness, you proceed
to disengage from the thought that had drawn your mind away, and steer your
attention back to your breath. A few moments later, the cycle will likely
repeat.
At
first it might seem like the tendency toward mind-wandering would be a problem
for the practice of FA meditation, continually derailing your attention from the
“goal” of keeping your mind on the breath.
However,
the practice is really meant to highlight this natural trajectory of the mind,
and in doing so, it trains your attention systems to become more aware of the
mental landscape at any given moment, and more adept at navigating it. With
repeated practice, it doesn’t take so long to notice that you’ve slipped into
some kind of rumination or daydream. It also becomes easier to drop your current
train of thought and return your focus to the breath. Those who practice say
that thoughts start to seem less “sticky”—they don’t have such a hold on
you.
As
a neuroscientist and meditator, I’d long been fascinated with what might be
happening in my brain when I meditate. Being familiar with both subjective,
first-person meditative practice and objective, third-person scientific
research, I wondered what would happen if I put these two modes of investigation
together. Could I get a more fine-grained picture of how this process works in
the brain by leveraging the experience of these cognitive shifts during
meditation?
I
started by considering the default mode network, a set of brain areas that tend
to increase in activity when we’re not actively engaged in anything else—in
other words, when our minds tend to wander. Maybe it was this default mode
network that kept barging in during my meditation, interfering with my ability
to keep my attention focused. And maybe this network was what I was learning to
“tune down” by practicing over and over. I wondered if I could test this
scientifically.
Supported
by funding from the Mind & Life Institute, and with the
help of colleagues at Emory University, I started to test which brain areas were
related to meditation. We asked meditators to focus on their breath while we
scanned their brains: whenever they realized their minds had been wandering,
they’d press a button. Then they would return their focus to the breath as
usual, and the practice would continue. As they did so, we collected MRI data
showing which brain regions were active before, during, or after the button
press that corresponded to various mental states.
The
study, published
in the journal NeuroImage,
found that, indeed, during periods of mind-wandering, regions of the brain’s
default mode network were activated. Then when participants became aware of this
mind-wandering, brain regions related to the detection of salient or relevant
events came online. After that, areas of the executive brain network took over,
re-directing and maintaining attention on the chosen object. And all of this
occurred within 12 seconds around those button presses.
Looking
at activity in these brain networks this way suggests that when you catch your
mind wandering, you are going through a process of recognizing, and shifting out
of, default mode processing by engaging numerous attention networks.
Understanding the way the brain alternates between focused and distracted states
has implications for a wide variety of everyday tasks. For example, when your
mind wandered off in that meeting, it might help to know you’re slipping into
default mode—and you can deliberately bring yourself back to the moment. That’s
an ability that can improve with training.
The
benefits of building focus
What
are other practical implications of this knowledge? Recent behavioral research
shows that practicing meditation trains various aspects
of attention. Studies show that meditation training not only improves
working memory and fluid
intelligence, but even standardized
test scores.
It’s
not surprising—this kind of repeated mental exercise is like going to the gym,
only you’re building your brain instead of your muscles. And mind-wandering is
like the weight you add to the barbell—you need some “resistance” to the
capacity you’re trying to build. Without mind-wandering to derail your attempts
to remain focused, how could you train the skills of watching your mind and
controlling your attention?
In
our study, we also wanted to look at the effects of lifetime meditation
experience on brain activity. In agreement with a growing number of studies, we
found that experience mattered—those who were more experienced meditators had
different levels of brain activity in the relevant networks. This suggests that
their brains may have changed due to repeated practice, a process called
neuroplasticity.
One
brain area stood out in this analysis: the medial prefrontal cortex, a part of
the default mode network that is particularly related to self-focused thoughts,
which make up a good portion of mind-wandering content. It turns out that
experienced meditators deactivated this region more quickly after identifying
mind-wandering than people who hadn’t meditated as much—suggesting they might be
better at releasing distracting thoughts, like a re-hash of a personal To Do
list or some slight they suffered at work yesterday.
In
a follow-up study, we found that these same participants had greater coherence
between activity in the medial prefrontal cortex and brain areas that allow you
to disengage attention.
This means that the brain regions for attentional disengagement have greater
access to the brain regions underlying the distraction, possibly making it
easier to disengage. Other
findingssupport this idea—more experienced meditators have increased
connectivity between default mode and attention brain regions, and less
default mode activity while meditating.
This
might explain how it feels easier to “drop” thoughts as you become more
experienced in meditation—and thus better able to focus. Thoughts become less
sticky because your brain gets re-wired to be better at recognizing and
disengaging from mind-wandering. And if you’ve ever struggled with
rumination—re-living a negative experience over and over, or stressing
(unproductively) about an upcoming event—you can appreciate how being able to
let go of your thoughts could be a huge benefit.
Indeed,
the Killingsworth and Gilbert study I mentioned earlier found that when people’s
minds were wandering, they tended to be less
happy, presumably because our thoughts often tend towards negative
rumination or stress. That’s why mindfulness meditation has become an
increasingly important treatment of mental health difficulties like depression, anxiety, post-traumatic
stress disorder, and even sexual
dysfunction.
Reading
all this might make you think that we’d be better off if we could live our lives
in a constant state of laser-like, present moment focus. But a wandering mind
isn’t all bad. Not only can we leverage it to build focus using FA meditation,
but the capacity to project our mental stream out of the present and imagine
scenarios that aren’t actually happening is hugely evolutionarily valuable,
which may explain why it’s so prominent in our mental lives. These processes
allow for creativity, planning, imagination, memory—capacities that are central
not only to our survival, but also to the very essence of being human.
The
key, I believe, is learning to become aware of these mental tendencies and to
use them purposefully, rather than letting them take over. Meditation can help
with that.
So
don’t beat yourself up the next time you find yourself far away from where your
mind was supposed to be. It’s the nature of the mind to wander. Use it as an
opportunity to become more aware of your own mental experience. But you may
still want to return to the present moment—so you can come up with an answer to
that question everyone is waiting for.

Be The Change: Today, when you realize
your mind has wandered far away from where it was supposed to be, don't be hard
on yourself. Instead, use it as an opportunity to become more aware of your own
mental experience, and gently return your focus to your
breath.
