A Simple Visual Hack to Boost Your Focus (Andrew Huberman)
Summary
TLDRThis script explores the relationship between visual and mental focus, emphasizing the role of neuroplasticity. It explains how visual focus can enhance mental concentration and suggests practices to improve it, such as maintaining a small visual window for attention. The discussion also touches on the impact of stimulants like caffeine and Aderall on alertness and focus, cautioning against their overuse. The script advocates for mindful engagement with learning materials to stimulate the brain's plasticity, contrasting passive consumption with active learning.
Takeaways
- 👀 Mental focus is closely linked to visual focus, and improving one can enhance the other.
- ☕ Caffeine can increase alertness by reducing adenosine, a molecule that induces sleepiness, which in turn can improve focus.
- 🚫 Aderall is often misused to enhance focus, but it primarily increases alertness rather than directly improving focus, and it carries a risk of abuse.
- 🌟 The brain's acetylcholine system plays a crucial role in focus and can be stimulated through visual focus exercises.
- 🔍 Visual focus can be trained to improve mental focus, with the trade-off between looking at a small area with high detail or a larger area with less detail.
- 🎯 To enhance focus, practice concentrating visually on a small area for an extended period, which can engage brain mechanisms for neuroplasticity.
- 📚 For optimal learning, focus on the material at the distance you intend to work, which can help develop depth and duration of focus.
- 📱 The small size and motion-rich content of phones can lead to a passive attentional focus that may not be beneficial for cognitive development.
- 💡 The brain's resources for focus are limited, so it's important to allocate them wisely between passive experiences and active learning.
- ⏳ Learning sessions should ideally last about 90 minutes, including a warm-up period, with the middle hour being the most focused.
Q & A
How does visual focus relate to mental focus?
-Visual focus is a mechanism that can be used to enhance mental focus. When we focus visually on a specific point, it activates neurons in the brain stem that trigger the release of neurotransmitters like norepinephrine, epinephrine, and acetylcholine, which are associated with increased mental focus and neuroplasticity.
What role does alertness play in focus, and how can it be achieved?
-Alertness is a prerequisite for focus and can be achieved through various means, including emotional states like love or fear, or pharmacological methods such as caffeine. Caffeine works by reducing adenosine, a molecule that induces sleepiness, thereby increasing alertness and potentially enhancing focus.
How does Adderall affect alertness and focus?
-Adderall increases alertness by stimulating the release of epinephrine from the locus coeruleus, which wakes up the brain. However, it does not directly increase focus as it does not affect the acetylcholine system. The perceived increase in focus might be due to the drug's ability to shift the autonomic nervous system towards a more alert state.
What are the potential issues with relying on Adderall for focus?
-Relying on Adderall for focus can lead to habit formation and abuse, especially in those not prescribed the medication. Additionally, learning on Adderall does not always translate to high performance off Adderall, and its widespread abuse raises concerns that should be discussed with medical professionals.
How can practicing visual focus improve overall focus?
-Practicing visual focus involves concentrating on a small visual area with precision, which can activate the brain's focus mechanisms. This practice can lead to increased mental focus and learning by engaging the brain's plasticity systems and releasing relevant neurotransmitters.
What is the tradeoff between looking at a small region with detail versus a larger area with less detail?
-The tradeoff is that we can either focus on a very small region of space with high detail and precision or dilate our gaze to see a larger area with less detail. We cannot maintain high-resolution focus across our entire visual field due to the density of receptors in the eye.
How does the brain respond when we focus our eyes on a specific target?
-When we focus our eyes on a specific target, our brain activates a set of neurons that trigger the release of norepinephrine, epinephrine, and acetylcholine. This response enhances our visual acuity and engages brain areas associated with gathering information from the focused location.
Why is it challenging for some people to focus on reading or listening compared to watching movies?
-Focusing on reading or listening can be challenging because our attentional systems have become accustomed to the motion and drama of movies and other visual stimuli. This makes it harder to attend to static text or audio, which are less stimulating and require more effort to extract information.
What is the significance of the 90-minute learning bout mentioned in the script?
-The 90-minute learning bout refers to the ultradian cycle, which is considered an optimal period for focused learning. It includes a warm-up period and a more intensive focus period. This cycle is believed to be effective for maintaining focus and enhancing learning and productivity.
How can one maintain focus during a learning bout?
-To maintain focus during a learning bout, one should eliminate distractions, such as turning off Wi-Fi and placing the phone in another room or out of reach. It's also important to re-anchor attention by continually bringing the focus back to the task at hand, even when it drifts.
Outlines
👀 Enhancing Focus Through Visual Attention
The paragraph emphasizes the intrinsic connection between visual and mental focus, suggesting that improving visual focus can enhance overall concentration. It introduces the concept of neuroplasticity and how alertness, which can stem from various emotional states or substances like caffeine, plays a role. The discussion also touches on the use and potential abuse of ADHD medications like Adderall, clarifying their effect on alertness rather than focus itself. The narrator advocates for behavioral practices centered on visual focus to develop depth and duration of attention, explaining the physiological mechanisms involved when we focus visually, such as the alignment of eyes and the brain's release of certain neurotransmitters that aid in focus and learning.
🔍 Practicing Visual Focus for Improved Concentration
This section delves into practical strategies for training visual focus to improve concentration, especially for tasks like reading or studying. It suggests focusing on a small area of a screen for 60 to 120 seconds to enhance visual acuity and stimulate related brain areas. The importance of a clear visual image is highlighted, and the narrator addresses the challenges faced by individuals with ADHD or ADD, recommending professional guidance for managing these conditions. The paragraph also discusses the impact of digital devices, particularly smartphones, on our attention span, noting how their small size and motion-rich content can capture our focus but also make it harder to concentrate on less stimulating tasks like reading text.
⏳ Managing Attention Span and Learning Cycles
The final paragraph discusses the importance of managing our neurochemical resources wisely, cautioning against devoting them to passive experiences that do not contribute to personal growth. It introduces the concept of ultradian cycles, suggesting that a typical learning session should last about 90 minutes, with a focus on maintaining attention during the middle part of this period. The narrator shares personal tactics for minimizing distractions, such as turning off Wi-Fi and even locking away one's phone, to foster deep immersion in a task. The paragraph concludes by emphasizing the need to refocus our attention when it drifts and the value of practicing visual focus to enhance learning and cognitive abilities.

Highlights
Mental focus is closely linked to visual focus, and improving one can enhance the other.
Neuroplasticity can be accessed through alertness, which can be achieved through various means including love, joy, fear, or pharmacological methods like caffeine.
Caffeine reduces adenosine, a molecule responsible for sleepiness, and can safely increase alertness.
Aderall, chemically similar to amphetamine, increases alertness but not focus, and has a high potential for abuse.
Visual focus can be developed by practicing precision and detail in looking at a small region or by dilating the gaze to see broader visual space.
The pupil's size relates to the fovea, the area with the highest density of light receptors, affecting visual acuity.
Focusing the eyes activates neurons in the brain stem, triggering the release of norepinephrine, epinephrine, and acetylcholine, which are crucial for neuroplasticity.
To improve mental focus, practice visual focus, especially at the distance you intend to work for better neuroplasticity.
The finer the visual image and the longer the gaze is held, the higher the levels of attention will be.
Attention drifts, but it can be re-anchored by maintaining visual focus on the learning material.
The use of mobile phones can lead to a low-grade form of ADHD due to the constant shifting of visual attention.
Motion and visual stimuli, like movies, naturally draw our attentional system, making it harder to focus on static text.
Successful learning often involves focusing on less exciting but more enriching activities, like reading or listening to podcasts.
The brain's neurochemical resources should be allocated wisely between passive experiences and active learning.
Ultradian cycles suggest that the typical learning session should last about 90 minutes, including a warm-up period.
Eliminating distractions and maintaining focus during the middle part of the learning bout can significantly improve learning outcomes.
Re-anchoring attention by visual focus is crucial for learning and can be practiced to increase focus and learning rates.
Transcripts
the best way to get better at focusing
is to use the mechanisms of focus that
you were born with and the key principle
here is that mental focus follows visual
[Music]
Focus we are all familiar with the fact
that our visual system can be unfocused
blurry or jumping around or we can be
very laser focused on one location in
space what's interesting and vitally
important to understanding how to access
neuroplastic itic it is that you can use
your visual focus and you can increase
your visual Focus as a way of increasing
your mental focus abilities more broadly
so I'm going to explain how to do that
plasticity starts with alertness that
alertness can come from a sense of love
a sense of Joy a sense of fear doesn't
matter there are pharmacologic ways to
access alertness too the most common one
is of course caffeine which reduces the
molecule that makes us sleepy called
adenosine caffeine can be a relatively
safe way to increase epinephrine now
many people are now also using adero
adero chemically looks a lot like
amphetamine and basically it is
amphetamine it will increase epinephrine
release from Locust culus it will wake
up the brain and that's why a lot of
people rely on it it does have a heavy
basis for use in certain clinical
syndromes prescribed such as attention
deficit however it also has a high
probability of abuse especially in those
who are not prescribed it Aderall will
not increase focus it increases
alertness it does not touch the
acetylcholine system and if those of you
that are taking Aderall say well it
really increases my focus overall that's
probably because your autonomic nervous
system is just veering towards what we
call parasympathetic you're really just
very sleepy and so it's bring your
levels of alertness up as I mentioned
ader is very problematic for a number of
people it has it can be habit forming
learning on Aderall does not always
translate to high performance off or on
Aderall at later times and the Aderall
discussion is a broader one that perhaps
we should have with a psychiatrist in
the room at some point because it is a
very widely abused drug at this point in
time the acetylcholine system and the
focus that it brings is available as I
mentioned through pharmacology but also
through these Behavior practices and the
behavioral practices that are anchored
in visual Focus are going to be the ones
that are going to allow you to develop
great depth and duration of focus so
let's think about visual Focus for a
second when we focus on something
visually we have two options we can
either look at a very small region of
space with a lot of detail and a lot of
precision or we can dilate our gaze and
we can see big pieces of visual space
with very little detail it's a tradeoff
off we can't look at everything at high
resolution this is why we have these the
the pupil more or less relates to the
phobia of the eye which is the area in
which we have the most receptors the
highest density of receptors that
perceive light and so our Acuity is much
better in the center of our visual field
than in our periphery and that's because
the density the number of pixels in the
center of my visual field is much higher
than it is in the periphery when we
focus our eyes we do a couple things
first of all we tend to do that in the
center of our visual field and our two
eyes tend to align in what's called a
virgin eye movement towards a common
point the other thing that happens is
the lens of our eye moves so that our
brain now no longer sees the entire
visual world but is seeing a small cone
of visual imagery that small cone of
visual imagery or soda straw view of the
world has much higher Acuity higher
resolution than if I were to look at
everything now you say of course this
makes perfect sense but that's about
visual attention not mental attention
well it turns out that focus in the
brain
is anchored to our visual system I'll
talk about blind people in a moment but
assuming that somebody is sighted the
key is to learn how to focus better
visually not only do we develop a
smaller visual window into the world but
we activate a set of neurons in our
brain stem that trigger the release of
both norepinephrine epinephrine and
acetylcholine norepinephrine is kind of
similar to epinephrine so in other words
when our eyes are relaxed in our head
when we're just kind of looking at our
entire visual environment moving our
head around moving through space we're
in optic flow things moving past us or
we're sitting still we're looking
broadly at our space we're relaxed when
our eyes move slightly inward toward a
particular visual Target our visual
World shrinks our level of visual focus
goes up and we know that this relates to
the release of acetylcholine and
epinephrine at the relevant sites in the
brain for plasticity now what this means
is that if you have a hard time Focus
focusing your mind for sake of reading
or for listening you need to practice
and you can practice focusing your
visual system now this works best if you
practice focusing your visual system at
the precise distance from the work that
you intend to do for sake of plasticity
so how would this look in the real world
let's say I am trying to concentrate on
something related to I don't know
science I'm reading a science paper and
I'm having a hard time it's not
absorbing I might think that I'm only
looking at the paper that I'm reading
I'm only looking at my screen but
actually my eyes are probably darting
around a bit experiments have been done
on this or I'm gathering information
from too many sources in in the visual
environment now presumably because it's
me I've already had my coffee I'm
hydrated I'm well well rested I slept
well and I still experience these
challenges in focusing spending just 60
to 120 seconds focusing my visual
attention on a small window of my screen
meaning just on my screen with nothing
on it but bringing my eyes to that
particular location increases not just
my visual Acuity for that location but
it brings about an increase in activity
in a bunch of other brain areas that are
associated with gathering information
from this location so put simply if you
want to improve your ability to focus
practice visual Focus now if you wear
contacts or you have or you wear uh
corrective lenses that's fine you of
course would want to use those you don't
want to take those off and use a blurry
image the finer the visual image and the
more that you can hold your gaze to that
visual image the higher your levels of
attention will be so you absolutely have
to focus on the thing that you're trying
to learn and you will feel some
agitation because of the epinephrine in
your system if you're feeling agitation
and it's challenging to focus and you're
feeling like you're not doing it right
chances are you're doing it right and
you can practice this ability to stare
for long periods of time without
blinking I know it's a little Eerie for
people to watch but if your goal is to
learn how to control that visual window
for sake of controlling your focus it
can be an immensely powerful portal into
these mechanisms of plasticity because
we know it engages things like nucleus
balis and these other brain stem
mechanisms I get a lot of questions
about attention deficit hyperactivity
disorder ADHD and attention deficit
disorder some people actually have
clinically diagnosed ADD and ADHD and if
you do you should certain certainly work
with a good psychiatrist to try and
figure out the right pharmacology and or
behavioral practices for you many people
however have given themselves a lowgrade
ADHD or add because of the way that they
move through their world they are
looking at their phone a lot of the time
it's actually very easy to Anchor your
attention to your phone for the
following reason first of all it's very
restricted in size so it's very easy to
limit your visual attention to something
about this big it's one of the um design
features of the phone the other is that
just as you you've probably heard a
picture is worth a th000 words well a
movie is worth 10,000 pictures anytime
we're looking at things that have motion
visual motion our attentional system
will naturally gravitate towards them
towards those movies it's actually much
harder to read words on a page than it
used to be for many people because we're
used to seeing things spelled out for us
in YouTube videos or videos where things
move and are very dramatic it is true
that the more that we look at those
motion stimuli the more that we're
seeing movies of things and things that
are very dramatic and very intense the
worse we're getting at attending to
things like text on a page or to
listening to something like a podcast
and extracting the information if you
think about the areas of life that
dictate whether or not we become
successful independent healthy
individuals most of those involve the
kind of boring practices of of digesting
information on a page boring because
it's not as exciting in the moment
perhaps as watching a movie or something
being spoonfed to to us but the more
attention that we can put to something
even if it's fleeting and we feel like
we're only getting little bits and
pieces shards of the information as
opposed to the entire thing that has a
much more powerful effect in engaging
this coleric system for plasticity than
does for instance watching a movie and
that's because when we watch a movie it
can the entire thing can be great can be
awesome it can be this overriding
experience but I think for all those
experiences if you're somebody who's
interested in building your brain and
expanding your brain and getting better
at various things feeling better doing
better Etc one has to ask how much of my
neurochemical resources am I devoting to
the passive experience of letting
something just kind of overwhelm me and
excite me versus something that I'm
really trying to learn and take away and
now there's another I enjoy movie
content and TV content all the time I
scroll Instagram often but
we are limited in the extent to which we
can grab a hold of these acetylcholine
release mechanisms or epinephrine and I
think that we need to be careful that we
don't devote all our acetylcholine and
epinephrine all our dopamine for that
matter to these passive experiences of
things that are not going to enrich us
and better us so that's a little bit of
an of an editorial on my part but the
phone is Rich with movies it's rich with
information and the real question is is
the inform information rich in for us in
ways that grow us and cultivate smarter
more emotionally uh you know emotionally
evolved or uh people or is it creating
how's what's it doing for our physical
well-being for that matter so I don't
want to tell people what to do or not to
do but think carefully about how often
you're focusing on something and how
good you are or poor you are at focusing
on something that's challenging so once
you get this epinephrine this alertness
you get the acetylcholine released and
you can focus your attention then the
question is for how long and in an
earlier podcast I talked about these
ultradian cycles that last about 90
minutes the typical learning bout should
be about 90 minutes that learning bout
will no doubt include 5 to 10 minutes of
warm-up period I think everyone should
give themselves permission to not be
fully focused in the early part of that
bout but that in the middle of that bout
for the middle hour or so you should be
able to maintain Focus for about an hour
so so that for me means eliminating
distractions that means turning off the
Wi-Fi I put my phone in the other room
if I find myself reflexively getting up
to get the phone I will take the phone
and lock it in the car outside if I find
myself going to get it anyway I am
guilty of um giving away the phone um
for a period of time or even things more
dramatic I've uh thrown it up on my roof
before so I can't get to it till the end
of the day that thing is pretty
compelling and we come up with all sorts
of reasons why we need to be in contact
with it but I encourage you you to try
experiencing what it is to be completely
immersed in an activity where you feel
the agitation that your attention is
drifting but you continually bring it
back and that's an important point which
is that attention drifts but we have to
re-anchor it we have to keep grabbing it
back and the way to do that if you're
sighted is with your eyes that as your
attention drifts and you look away you
want to try and literally maintain
visual focus on the thing that you're
trying to learn feel free to Blink of
course but you can greatly increase your
powers of focus and the rates of
learning
