How do we learn?
Learning another language is often a daunting task. There is so
much to learn. Japanese seems especially difficult because not
only do you have to learn a completely different language, but
you also have to learn a completely different kind of writing.
In fact, there are 3 different kinds of scripts in
common use in Japanese.
How can we hope to learn this? As it turns out, there are
several characteristics of our brains that we can exploit in
order to learn faster. The best thing about learning Japanese
is that nothing in it is conceptially difficult. By
and large it is just a matter of memorization.
But I'm bad at memorizing stuff
Don't worry. Most people are bad at memorizing stuff. Or at
least they think they are. In truth, most people are actually
pretty good at remembering things. If I give you an oatmeal
cookie and then take it away, you will remember that I gave you
an oatmeal cookie. What is lacking is a way to tell the brain
that you want to store this information for long term use.
The Wikipedia links provided above give a good description of the
system, but I will expand a little with my visualization of
what's going on. Keep in mind that I'm not a psychologist (I
need a spell checker to even be able to write the word), so this
is just how I think about the system. My understanding is
probably completely incorrect from a factual standpoint, but
I still find it a useful way of thinking.
Basically, the brain has two modes of information storage: short
term memory and long term memory. My understanding is that this
functionality is located in two physically separate parts of the
brain. When you experience something for the first time the
information is stored in the short term memory (henceforth known
as STM). When you try to recall something in STM, it's
available immediately, and in pretty good detail most of the
time.
So in otherwords, if I tell you that the Japanese word for fish
is "sakana", and then ask you immediately "What is the Japanese
word for fish", you will search your STM and probably get the
word "sakana". But sometimes you don't. Sometimes you will
remember "hakana" or "sakene" or something similar. This is
because the memory pathways didn't get laid down strongly
enough.
Our memory isn't like a computer's memory which either remembers
something or doesn't. It's "fuzzy". In other words, we might
remember the association of "fish" to the Japanese sounds "sa",
"ka", and "na", but some of the associations might be stronger
or weaker than the others. Some might be downright wrong. So
in order to make the memory better we need to "reinforce" it.
Luckily, our brains automatically reinforce stuff. There's very
little we have to do, consciously, to reinforce the memories in
our brains. We just have to re-experience it. So the first
time we see "sakana", we might remember "habana". The second
time "sabana" and the third time "sakana". By the third time,
the connection is quite strong and we are very likely to
remember it.
Which leads me to "forgetting" things. The "memory" in the STM
area is constantly being reused. There's only a limited amount
of it. Some research indicates a limit of 7 concepts that can
be stored in STM at one time. To indicate this, try to
visualize one jelly bean. Easy, right? Now two. Not bad.
Keep adding jelly beans and try to see how many you can
visualize at the same time. It will probably be about 7
(actually, it's 5 for me). After that you start to envision 2
or 3 groups of objects (for instance, a group of 4 and a group
of 3) rather than individual objects.
The point is that you can only store so many things in your STM.
And since your brain is constantly storing stuff there
automatically, you are bound to "damage" the stuff there. But
luckily our brains are "fuzzy". As we bring new things into the
STM, we only weaken the associations of the old things. They
don't go away entirely. Of course, eventually they become so
weak that they disappear. But if we continually reinforce a
concept, its associations will remain strong.
Storing for the long haul
This is a wonderful way of remembering stuff. I recall seeing
an animated short on
Sesame
Street where a kid walks to the store mumbling "Quart of
milk, loaf of bread, and a stick of butter" over and over again
until he gets to the store. Lo and behold, when he gets to the
store, he remembers what he wants to buy. Buy unfortunately we
need to remember more than 7 words (or 5 in my case!)
What we need to do is store some of this data for the long haul.
Fortunately we have another memory system called "long term
memory" (or LTM) for doing this. Without any conscious
interaction on our part, items that have strong associations in
our STM automatically get stored in our LTM.
Amazing! So all I have to do is continually reinforce a concept
over and over until it's "strong" in my STM and then it will
automatically get stored in my LTM. Wonderful! Except that
there are a few problems (you knew it, I bet!).
First, the storage of the associations from STM to LTM memory
isn't perfect. The way the brain works is that it will
strengthen or weaken "associations". It doesn't do a verbatim
copy. So, having strong associations in STM will strengthen the
associations in LTM, but they might not be strong enough to get
the correct answer.
Second, you can't access your LTM memory directly. When you try
to "remember" something, it takes associations out of your LTM
and strengthens those associations in the STM. So the copy out
of LTM can be faulty. As a side note, the associations in the
STM are altered as normal and stored back in the LTM. This
means that everytime you "remember" something, you will be
altering it slightly. This fact is used in "brainwashing"
techniques where they can use an existing memory in LTM,
continually bring it back, alter it, and store it in order to
make you believe that you remember something that never
happened.
Finally, your LTM is also finite. It is constantly being
overwritten by other things. Over time, the associations will
degrade and you will eventually forget things (or remember them
incorrectly). So don't be too sure about your memory. The fact
that remembering something alters that memory and the fact that
memory degrades over time means that it is entirely possible
that things you remembered are not correct at all.
The Technique
So now it seems hopeless again. Sure I can memorize a bunch of
stuff and put it in my STM, but there's no way that I can
reliably shunt it back and forth between LTM. In fact, those of
us who are "bad at memorizing" can probably relate to this. I
sit down and memorize a whole bunch of things and can remember
them. But a week later it's all gone...
But let's look at this from the perspective of understanding
what's going on (or at least understanding my fantasy of what's
going on...). As you memorize stuff the associations get rather
strong in the STM. And as the associations get strong in the
STM, the associations are strengthened in the LTM. And as you
study, you recall the information from the LTM, strengthening
the STM. And so we can "remember" everything and think we must
"know" it.
But over a weeks time period, you don't move the information
from LTM into STM. And so the associations get weaker (you're
storing other information during that week). And after some
period of time, they are so week that you can't "remember" it
any more. So how do we combat this?
Well, we could do the old Sesame Street technique of constantly
reviewing material. But the problem is that there's a limit to
how much material we can review at once. For me, it takes about
30 minutes to review 100 words of vocabulary. So if I wanted to
have a vocabulary of around 1500 words (about the number of
distinct words used in the average manga) I would have to study
for about 8 hours a day. This is clearly impossible. But it's
also unnecessary.
Because we have a lot more LTM than STM, the associations
degrade much slower. What we need to do is merely strengthen
the associations to the point that they will stay active between
the periods that we are likely to run into the word on a normal
basis. Studies have shown that you can stengthen an association
to the point that it takes several months to forget it, even if
you aren't exposed to it again.
So we can just continually refresh our memories with a concept
until it's that stong. But how do we know how many refreshes
that is? And ideally, we want to optimize for having the
largest possible "working set" of information at all times.
That is, I'd rather be able to just barely remember 1000 words
than have 100 words really well memorized, as long as eventually
those 1000 words are well memorized.
That's where "Spaced Repetition" comes in. What we do is
"learn" a concept (piece of vocabulary, or grammar point), by
getting it to the point that it is strong in our STM.
Automatically, this will reinforce the concept in our LTM. The
next day we recall the information from LTM. This will
automatically strengthen the associations. 2 days after than,
we do it again. Then 4 days, 8 days, etc, etc...
Usually after about 8 correct repetitions, the concept will be
firmly implanted in the LTM. You can verify this because the
8th repetion actually occurs nearly 4 months after the 7th
repetition. If you remember it then, you're going to remember
it forever.
However, if at any point we recall the information incorrectly
or can't remember it, we need to start all over again. That's
because the associations have degraded to the point that we
might be strengthening them improperly. So, if after recalling
it correctly 4 times in a row, I get it wrong after the 5th
time, I'll start back to day one.
The idea is to schedule your reviews so that you wait as long as
possible (in order not to waste your time), but that you still
remember the item (so that you will be reinforcing it
correctly). This can be done (awkwardly) with flash cards (as
described in the Wikipedia article on flash cards above). But
it's so much simpler to get a computer to keep track of the
scheduling for you. Later I will introduce you to some free
software that does this.
The important thing to remember here is that using "spaced
repetition", we can vastly increase the speed at which we are
"memorizing" material. In fact, it's not so much that we are
increasing the speed, but since we don't spend time reinforcing
material that we already "know" we can increase our "working
set" of knowledge.
The other really important thing to realize is that tests have
shown that humans by and large require the same number of
repetitions in order to reinforce the associations in the brain.
The ability to memorize is independent of the concept we
know as "intelligence". Average people are able to
memorize at about the same speed as "brilliant" people. It's my
opinion that some people are better or worse at memorizing than
others, but the average person is well capable of memorizing an
astonishing amount of material quickly.
Aren't we going to read manga?
I've talked a lot about memory and memorization here. But
aren't we going to learn to read manga? Of course. But you
need to realize that you are going to be spending some time
reviewing material. In fact, you will spend far more time
reviewing material than you will spend reading manga. But
that's so that we will eventually be able to read manga at a
reasonable speed.
As it turns out, reading manga is relatively easy. You just
need to have 3 things: a Japanese to English dictionary, a
dictionary of Japanese grammar, and a table of Japanese
characters. You look at a sentence in the manga and
transliterate the characters into characters you can type into
your computer. Then you type the words into your computer and
have the dictionary look up the meanings. Then you look up the
grammar of the sentence in the grammar dictionary to figure out
what the sentence means. Easy as pie.
Only it will take you about 30 minutes per sentence to do it
that way (strangely I know this from experience...) And it will
be extremely difficult to determine what words you are using if
you don't understand the grammar first (since the grammar
modifies the words and the dictionary only lists unmodified
words). But it's hard to figure out the grammar without knowing
the words.
So what we need to do is memorize a few things. The most
important is the Japanese characters (don't worry, there's only
about 150 that you actually need to memorize to read this book).
This speeds things up tremendously. Then we need to memorize
the vocabulary and grammar.
I will be guiding you through the Japanese language using the
manga. As we experience new characters and new vocabulary and
new grammar, I will explain them (heavily using outside
materials) and then get you to memorize them. At first there
will be a lot of memorization, but by the time we get to the end
of the book, you will be able to go through large sections
without having to memorize anything.
Mahoraba volume 1 is 178 pages long. On average we will
probably be doing about 1 page per day. Which means that it
will take roughly half a year to read the whole manga. As I
said, there are about 150 characters to learn, 1500 words to
learn, and roughly 300 grammar points. So in total 2000 items
to memorize.
In a typical day I will discuss the content of the material we
are reading for that day. I will then assign 10-15 new items to
memorize for that day. You will do the initial memorization for
those items and then review the items that the software has
scheduled for review. Finally you will read ahead for the next
days material to see how much you can understand.
We will only read enough material to get 10-15 new things to
memorize for that day. At the beginning that will be a
pathetically small amount of the manga. But as we learn more,
the amount that we can read each day will become larger and
larger. By the time we get to the end of the manga, you will be
able to read other mangas fairly comfortably with the aid of a
dictionary.
