The Proper Way to Improve Your Memory: Tips from a Neuropsychologist
Summary
TLDRThis video discusses the importance of memory and how to improve it through four key methods: getting quality sleep, deeply processing information, using the retrieval practice effect, and maintaining a healthy lifestyle. Sleep helps the brain reorganize, while deeper processing of information enhances retention. Regularly recalling information strengthens memory, and healthy habits like exercise and a good diet boost brain function. The video emphasizes how memory is reconstructed over time and provides research-backed tips to improve memory performance in everyday life.
Takeaways

Q & A
Why is memory considered important in everyday life?
-Memory is essential for navigating the world, remembering conversations with friends, recalling information for exams, and more. It enables us to function efficiently in daily activities.
What is the basic definition of memory as explained in the video?
-Memory is described as the process of combining all sensory experiences—such as sight, sound, emotions, and taste—into a unified 'packet' and storing it in the brain for later retrieval.
How does sleep contribute to memory improvement?
-Sleep helps the brain with essential tasks like removing toxins, reorganizing information, and enhancing efficiency. Studies, including those on orangutans, show that better sleep correlates with improved memory performance.
What is the significance of the Craik and Lockhart study on memory?
-The Craik and Lockhart study demonstrated that deeper processing of information (focusing on meaning) results in better memory retention, as opposed to shallow processing (focusing on appearance or sound).
What is 'retrieval practice' and how does it improve memory?
-Retrieval practice refers to the act of actively recalling information from memory rather than passively reviewing it. This process strengthens memory by reinforcing the memory trace each time it's recalled.
What are some lifestyle factors that contribute to better memory?
-Exercise and a proper diet rich in brain-healthy foods, such as fatty acids found in fish and nuts, improve oxygen flow to the brain, which enhances cognitive functions, including memory.
How does processing information more deeply improve memory retention?
-Processing information deeply—such as thinking about the meaning of a word—creates stronger memory 'packets,' making it easier to remember the information later compared to shallow processing.
Why is good sleep linked to better memory, according to research on orangutans?
-Research shows that orangutans who sleep well, using high-quality materials like memory foam, perform better on memory tests. This suggests that quality sleep helps the brain with memory retention.
What is the 'reconstruction' process in memory retrieval?
-Memory retrieval involves reconstructing experiences from stored information rather than accessing a 'file.' Each time we recall something, we reconstruct it based on what we remember from our previous recall.
Why is passive information intake less effective for memory retention?
-Simply taking in information passively, such as writing down lecture notes without processing them, does not help with long-term memory. Deep thinking about the information strengthens memory more effectively.
Outlines
🧠 Understanding Memory and Its Importance
The speaker introduces the concept of memory and its vital role in everyday life, such as remembering conversations and studying for exams. While memory isn't fully understood, it involves combining information from various senses and emotions into a 'packet' stored in the brain. Memory isn't a perfect filing system but a reconstruction of what we remember from our senses and feelings. The speaker emphasizes the importance of understanding memory to improve it and previews four techniques to enhance memory.
💤 The Role of Sleep in Memory Improvement
The speaker explains that sleep is crucial for memory improvement, not just for physical rest. During sleep, the brain performs essential tasks like removing waste and reorganizing information. Research, including studies on orangutans, shows a clear connection between good sleep and improved memory performance. The speaker highlights that deep sleep (monitored through rapid eye movement) correlates with better memory, and people or animals who sleep well perform better in memory tests. Thus, pulling an all-nighter before exams is counterproductive, as sufficient sleep enhances brain health and efficiency.
🔍 Deep Processing for Better Memory Retention
This paragraph introduces the findings of Craik and Lockhart, who demonstrated that the deeper we process information, the better we retain it. In their study, students who judged words based on their meaning (deep processing) remembered them better than those who focused on appearance or sound (shallow processing). The speaker emphasizes that passive learning, such as copying notes verbatim, is ineffective. Instead, students should engage with the material by thinking about it deeply. This active processing helps form stronger 'packets' of memory and leads to better long-term retention.
🔄 Retrieval Practice: Strengthening Memory
The speaker discusses the 'retrieval practice effect,' which shows that actively recalling information improves memory retention more than passively reviewing it. In studies, students who recalled material themselves performed better than those who repeatedly received the same information. The process of recalling and reactivating memory traces strengthens them, creating multiple layers of memory. The speaker advises testing oneself rather than just rereading, as the act of recalling reinforces and strengthens the memory packet, even if the recall is initially inaccurate.
🏋️♂️ Lifestyle Factors: Exercise and Diet for Memory
In this section, the speaker explains how general lifestyle choices, such as regular exercise and a healthy diet, positively impact memory. Exercise increases oxygen flow to the brain, improving cognitive functions like memory and language. Certain foods, especially those rich in fatty acids (found in fish and nuts), are also beneficial for brain health. A healthier brain is more efficient, and by focusing on overall well-being, one can enhance memory and other cognitive abilities. The speaker summarizes the four memory-boosting strategies: sleep, deep processing, retrieval practice, and healthy living.

Highlights
Memory is a coming together of all the information you experience, involving your five senses and emotions, which creates a 'packet' that gets stored in your brain.
Memory is not like a filing system but a reconstructive process where we try to recall what we experienced, heard, and felt.
Sleep plays a crucial role in memory as it helps in cleaning and reorganizing the brain, making it more efficient.
Research on orangutans shows a correlation between sleep quality and memory performance, demonstrating that better sleep leads to better memory.
Humans also benefit from sleep for memory. A good night's sleep improves memory recall, while bad sleep hampers it.
The theory suggests that developing better sleeping materials was a critical step for our ancestors, enabling improved brain function and helping humans evolve.
Deep processing of information leads to better memory retention. Thinking about what information means is more effective than just observing or hearing it.
A study by Craik and Lockhart showed that students who thought deeply about the meaning of words had much better recall compared to those who only looked at or listened to them.
The retrieval practice effect shows that actively recalling information strengthens memory more than merely reviewing it multiple times.
Repeatedly recalling information creates layers of memory traces, making the memory stronger and more durable over time.
Testing yourself on information, even if you don't recall everything correctly, helps reinforce your memory through retrieval practice.
General lifestyle factors like exercise improve memory by enhancing brain oxygenation, leading to better cognitive functioning.
Certain foods, such as those containing fatty acids (found in fish and nuts), promote brain health and improve memory.
Improving memory involves four main aspects: sleep, deep processing of information, retrieval practice, and maintaining a healthy lifestyle.
The video also offers longer explanations on memory disorders, memory function, and other techniques for improving memory, emphasizing the value of further learning.
Transcripts
hello today i want to tell you about
memory
and how we can improve our memory now
all of us
me my friend frank here presumably you
would like to have a better memory
because memory is really important for
our everyday lives
to allow us to navigate around the world
to remember what our friends said
remember things for an exam etc
therefore how can we improve this
really important skill now to start with
it's really important to know what a
memory is now although we don't know
fully what a memory is
what we do know is that it's a coming
together of
all of the information that you're
experiencing and somehow
patching those together so right now
you're
hearing me you're hopefully seeing me
you've probably got um feelings that
you've got at the moment
maybe excitement boredom who knows uh
you might have a taste in your mouth
from what you've just
eaten etc so at the moment you're
experiencing
your five senses and also some emotions
from inside
now what memory involves is bringing
those five separate things
together and creating a packet
and then somehow storing that packet
inside your brain so that you can find
it later on
another important thing is that memory
involves
not a filing system where you go in and
just pick something out
it's actually a reconstruction we go in
and we try to find a memory
and we reconstruct what we thought we
saw what we thought we heard what we
thought we felt
etc now knowing these two things
is really important for helping us
understand
how to improve memory i'm going to go
through
four different things that can help you
for improving your memory now the first
is something that you wouldn't have
thought of
which is sleep now most people think of
sleep as being important for physical
rest after a tiring day etc etc
now yes it's useful for that but
actually
one of the main purposes of sleep is to
tidy up and
clean up the brain there are physical
things that the brain needs to do
it needs to get rid of waste material
and toxins
but it also does a lot of spring
cleaning and reorganization during sleep
so that it can be more efficient
now we know this from lots of different
uh bits of research
but one of my favorites is lovely
orangutans
now did you know that orangutans make
beds
and nests so in the wild
they will use different materials to
make a nest for the night
to have a good night's sleep
now what does that mean well
when animals or orangutans
who are in research areas
are in a particular enclosure you can do
experiments
where you can leave different types of
material for them to use for making
their nests
so you can leave them just sacks and old
mattresses
or you can leave them memory foam
mattresses
and nice duvets and nice pillows
and what have been found is that
orangutans will
always use the highest quality material
they can find
so if an old mattress is the best thing
they've they can find they'll use that
and if an
old sack is the best thing that they've
got to use
to cover themselves they'll use that but
if there's memory foam around
and nice duvets they'll use those okay
so they're clever at building beds so
what well the so what is
the following day you can test their
memory
now we can test how good their sleep is
by looking at their rapid eye movements
which is a part of our sleep
where we go really deep into
a sleep mode and so we can tell
which of the orangutans have had really
good sleep which have had
an okay sleep and which have had a bad
sleep
then we can do memory tests on them the
following day
and what we find is there's a clear
connection
or correlation between how well they
slept
and how well they do on the memory test
the ones who slept the best
did the best in memory and there is a
theory
that it was our ability to develop
better sleeping materials
when we were still living up in the tree
canopy
that gave us the best advantage for our
brains
to allow us to leave the trees and walk
on the open savanna
and become the successful species that
we have
we also know with humans that um
a good night's sleep helps with memory
tests
bad sleep is really bad for memory
and therefore what we're beginning to
understand is that sleep isn't just for
rest
sleep is for brain health
and brain efficiency so the idea of
sleep is for wimps and pulling an
all-nighter
before an exam is quite idiotic
you are actually working against nature
if you try to do that you should be
trying to get good sleep
to allow your brain to do its best for
improving your memory the second way of
improving memory
comes from a really important study done
by two people called craic and lockhart
in toronto and the basic gist of the
work that they did
was to demonstrate that the more deeply
you take information
in the more likely you are to remember
it
so they did study in which they got
groups of students
either to just make a statement about
what a word looked like
or what it sounded like
or what it meant so
they got students to do this just make
judgments on words
what it looks like what it sounds like
what it means
half an hour later completely
without warning so students didn't know
that they were going to be tested later
on
they gave them a sheet of paper and said
just take any words that you can
remember from before what they found
is that the group that did what they
called the shallow processing
just this look of the word performed
very poorly they couldn't remember any
of the words
the ones who did an intermediate type of
processing
so the sound of the word they did a bit
better but not great
the ones who did the deepest processing
which is thinking about the word they
did
best in remembering later on and this
was a really important finding for
showing that
it's what you do with information that's
important
just taking it in passively is not
helping
now if we go back to our packet
effectively what you're doing is just
creating a stronger packet
by processing the information deeply
rather than just at least
if you just kind of look at the words
and write them down now i can
guarantee you that my students
who just write down verbatim what i say
in a lecture
without thinking about it so straight
into their ears towards their hands
bypassing their brain really
not really thinking about it they're not
going to remember anything
the ones who sit back like this and
think hmm what's
your saying and then thinking about it
and then writing something down
afterwards about what they're thinking
they're going to do much much much
better
later on in a test because they've done
a deeper level of processing
so when you're taking information in
don't do it passively
think about it play with it that
improves the chances of creating good
packet
the third thing is known as the
retrieval
practice effect now this is a really
interesting effect
and what it generally demonstrates is
that
simply by activating your memory again
by thinking about it bringing it up
then just letting it go back breathe up
letting it go back is much better
than just trying to bring it in from the
outside
so in a research study students
were either given the same information
a number of times so as if they were
getting the same
lecture or lesson a number of times
three times four times
another group only got it the one time
but they were asked to think about it
three or four times so one group is
having the information repeatedly told
to them
the other group is repeatedly recalling
it themselves
and what's been found is that the group
that actively tries to bring up the
information themselves
they do better and that's called the
retrieval practice effect
bringing it back up is actually really
beneficial to your
overall memory now in terms of the
packet etc
what we know is that as i said earlier
memory isn't a filing system
it's a reconstructive process later on
when you're thinking about this video
which i hope you will
what you're doing is you're trying to
think about what you
saw what you heard and you're trying to
reconstruct
what happened and if you've created
really strong
packet you're more you're likely to do
well
but we also know something rather
interesting
that when you recall this
you will be now laying down a new memory
trace
of your memory of this event and then
the next time
you will be trying to recall your memory
of your memory
of this event it sounds weird but trust
me
we know it happens so what you get
in this packet thing is that you get
layers building up each layer
is your last recall of the event
and that practice is creating
a stronger and stronger
packet and a stronger memory overall
and therefore what the retrieval
practice effect is doing
is effectively strengthening the memory
trace that you've got
so one of the things that you can do is
rather than just passively reading it
over and over again test yourself it
doesn't matter whether you get it right
or wrong
literally the act of trying to recall it
is reactivating that memory and then
laying it down again
is strengthening it and then you can add
to it
when you realize you've got something
wrong but literally just
recalling it again is really good for
you now
the fourth thing is general lifestyle
now we're beginning to know that things
like
exercise and diet are really helpful
now exercise is good because it's
helpful
for getting oxygen into the brain
the more oxygen you can get into the
brain for the brain to be moving
and using itself more efficiently
rather than being really sluggish the
better for your
overall brain health and for your
cognitive
functions such as memory your language
your thinking your
etc etc so general exercise is going to
be beneficial
we also know that there are certain
foods that are really good for brain
health
and these include things like certain
types of fatty acids that are found in
lots of different types of fish
nuts etc so look up
what types of foods are good for brain
health because what you're doing there
is improving
the health of your brain and if you have
a more healthy brain it's going to
function better so we've got
four ways that i've given you the first
is to do with better sleep the second
is to take information in more deeply
with the levels of processing effect the
third is the retrieval practice effect
which is try to recall information
because that
strengthens your memory and then the
fourth is
general lifestyle things such as
exercise
and diet if you want to know more
i've got longer videos on what memory is
how memory can go wrong in memory
disorders and also
a longer video on improving memory
what i'd like you to do is make any
comments
in the comments section here and please
like the video and
please recommend this video and
my channel to other people because we're
trying to improve the number of
subscribers we have
so that we can create more content for
you i hope you found this useful
and look forward to giving you another
