High-efficiency memory method of the University of Tokyo

Chapter 4 3 Steps to Efficient Memory: Associative Repeated Application (2)
Many human memories are carried out in chronological order.Therefore, books arranged in chronological order are easier to find.It is obviously a pity that such a convenient time-lapse method is not used in the memory method.So there is the law of memory associated with the passage of time.

The best way to associate time-lapse is with journaling.Writing down what happened that day, attaching the date, just like this can help us improve our memory.

In fact, we don't need to record all the things that happened that day in the diary, just simply write down the things that happened that day in the schedule booklet, it will have a considerable effect.This is the key to strengthening your memory.Because this kind of training allows us to extract the keywords with the strongest impression from the events that are organically connected.

Writing down what happened that day, attaching the date, just like this can help us improve our memory.

Write down what you remember that day in your study diary

It is recommended that you write a study diary instead of an ordinary diary.The point of this method is to record the key words and dates of the things remembered that day.

For example, if you are studying the European situation at the end of the 19th century in world history, then write down keywords such as "European situation at the end of the 19th century".And of course don't forget the date!

It doesn't matter if the keywords are short, just record the first two or three.We can use these keywords as a breakthrough to dig out the knowledge we remembered together at that time from our memory.Compared with the method of writing down all the keywords and rereading them, this method can obviously strengthen our memory.

In addition, if you want to ask the teacher if you have any questions, you should also record the questions.

When reviewing, use the method of blank paper recovery

When writing a study diary, first of all, you can't look at anything.I call this method "blank recovery".The specific method is to write down two or three keywords, and record the page numbers and scores of the reference books or exercise books that come to mind.

When performing blank paper restoration, if there is something that we can't think of, we can open the class timetable or schedule to take a look.In this way, you should be able to naturally think of the courses or content you have learned that day, and then write those courses or content you remembered into your diary.

If you still can't remember after looking at the class timetable or schedule, then take a look at your notebook or notepad.This step should be able to remember.

When writing a study diary, also increase the intensity like this.Don't just look at the notebook at the beginning, first try the blank paper recovery method.If it is a bit difficult, then look at the timetable or schedule; if it is still difficult, then look at the notebook or notepad.Adjusting the intensity in this way is also a kind of exercise for memory.

Relate mathematical formulas to the order in which they are actually used

Where the method of time-lapse association can be used, the method of sequential association can also be used.The so-called order refers to the flow of things, similar to the flow of "do this, then do this, and then do this".

For things that are prepared or in order, we must sort out the order in advance.By associating things in this order, it becomes easier to remember when you need to use that thing in real life.

For example, when learning mathematics or physics formulas, one must not only memorize the derivation method of that formula, but also know how to use it when solving problems.

connect with place
Surrounding information helps to dig out memory information

When we grasp new information, we must acquire it somewhere.Being connected to that place can make the remembered knowledge into a deeper memory.Therefore, while studying, please also pay attention to the information around you.

For example, if you are studying in a coffee shop you frequent, observe the shop before starting to study, feel the atmosphere, and then start studying.

If you see beautiful furniture, spot an interesting customer, or smell a unique aroma of coffee, remember them.

In this way, if the place information is also remembered, you can associate it with the coffee shop with beautiful furniture when you think about it later, so as to salvage the things remembered in that place from the ocean of memory.

Connect the surrounding scenery with the content to be memorized
We can also connect what we saw on the spot with what we are remembering.

For example, if you are studying the French Revolution in world history in a certain coffee shop, you happen to see a somewhat strange customer.In this case, we can imagine that customer participating in the French Revolution.

This strange customer has a special message in itself and is easy to impress.If you can use this character to remember knowledge, the memory will definitely be very deep.

You may think that observing the surrounding situation when you are about to memorize something or understand something, isn't that a distraction?This is not the case.Connecting with surrounding information can indeed effectively improve memory.

connect with a sense of meaning or purpose

The moment I wonder why I should remember, it becomes difficult to remember

The so-called connection with meaning or sense of mission refers to making yourself think that remembering this thing is of great benefit to yourself or to society.

We often have the feeling of "busy every day, but don't know why".If we have been unable to find meaning or sense of mission like this, once a certain limit is exceeded, the idea of ​​not wanting to do this will emerge in our minds.

So does memory.

For example, when you couldn't remember the homework you learned in school when you were a child, everyone may have such a question: "What good is it for me to remember such knowledge?"

Human memory has a mechanism for trying to forget bad experiences.Therefore, in the process of memory, if negative feelings such as "I don't know what it is for or it doesn't make sense" are mixed in, it will be difficult for us to remember this information.

Because of this, it is very important to have a strong sense of what to remember.

Things that have meaning or mission are more likely to be remembered with ease and joy
No matter what you do, you will find it more interesting if you know its meaning or mission.

For example, learning is like this.

People who think that their parents or school teachers are forcing them to study will feel that they don't like studying.But if these people can find that studying mathematics strengthens logical ability and knowing world history broadens their horizons so that learning makes sense, the learning process will become interesting and memory will not be boring.The result is a boost in our memory.

The same goes for learning after leaving the campus.

Learning English can make your overseas travel more enjoyable.With a little more effort, we can also work in a more international environment and find overseas business opportunities.In addition, if we accumulate more business knowledge, in addition to ourselves, we can also make the company's colleagues or customers feel happier, thus increasing the possibility of broadening our own development.

Please try to discover the meaning or mission of what you are learning.Knowing the meaning or mission, all kinds of knowledge are integrated by the meaning and mission, and there is a relationship between them, making it easy to memorize.

link to the rules

Is there a dot in the upper right corner of the word "Bo"?
Seemingly messy knowledge, as long as you see through its rules and connect it with the rules, it will be easy to remember.There are two methods of memory:
The first is to remember the rules first, and then associate each knowledge with the rules.

The second is to master the rules after reciting the scattered knowledge to a certain extent or to discover the rules by yourself.In this way, the scattered knowledge is linked to the rules, and we can memorize them in one go.

Give a concrete example.For example, there are two Chinese characters "Bo" and "専". The right half of the word "Bo" is very similar to "専". There is a "dot (,)" in the upper right corner of the character "Bo", but there is no such dot in the character "専".For these two Chinese characters, it is easy to confuse whether it is a bit or not.

Similar Chinese characters include Bo, Bie, Book, Fu, Hui, Sui and so on.It is not so difficult to remember which word has a dot in the upper right corner and which word does not.In fact, it has the following rules:
"It's a little bit in phonetic reading (that is, Japanese ハ (read ha) line, バ (read ba) line).

That is to say, dots should be added to Chinese characters such as "thin: はく (read haku)", "结: ばく (read baku)", "book: ぼ (read bo)", "底: ふ (read fu)" and other Chinese characters; and "惠:けい (read kei)" and "羽:すい (read sui)" are not dotted.

At the same time, is the right half of "ハ" (pronounced ha) very similar to "dot (,)"?If you connect with this impression and remember that "when you read 'ハ' (read ha), you need to add "dot (,)", then these Chinese characters can be easily remembered.

Section content:

Seemingly messy knowledge, as long as you see through its rules and connect it with the rules, it will be easy to remember.

For more complex things, we have to work hard on supplementary association methods
Among the Chinese characters we saw above, "羽: すい (pronounced sui)" is more difficult to remember.That's because this Chinese character also has a "sui: ほ (read ho)" pronunciation, and it also belongs to the "Japanese ハ (read ha) row".

At this time, we have to decompose the character Sui of the ear of rice, and remember that "'sui' is 'he' plus 'hui'", which means "the grace of grain". There is no dot in the word "Hui", so there is no dot in Sui.that's it.

The more associations, the stronger the memory

The length of memory duration depends on the number of associations

There are many ways of associating.Listed here (below) are the main associative methods.In addition, Lenovo has many methods.

Connect with Chinese characters.

Link to questions.

Link to the purpose, use, and method of use.

linked to interests.

Connect with etymology and solution.

connect with cause and effect

The more associative methods, the stronger the memory.

In other words, even when remembering the same knowledge, if we use multiple association methods, we can remember it more firmly.Connect with cause and effect, connect with experience, connect with place... and so on, it is not easy to forget.In class, I also made associations over and over again.

If you want to increase the method of association, you need to have the ability to associate with infinite changes.On the one hand, I often feel that students have too few association methods; on the other hand, students who can memorize quickly have a stronger ability to find out their own unique association methods for the knowledge being taught.

The firmness of memory depends on the number of associations.The more associative methods, the more opportunities for memory, and the easier it is for knowledge to be remembered.The process of association will become a review, which can make the memory more durable.

Because of this, please refer to this book, try various transformations of association methods, and work hard to master the essentials.

If you want to increase the method of association, you need to have the ability to associate with endless changes.

Repetition helps improve memory
Temporarily hug Buddha's feet, forget all night
Next, let's look at the second major element of memory - repetition.

Repetition is review.Reviewing is very important.Reviewing ensures that knowledge is retained, and it also makes memory last longer.

Simply put, the length of memory is directly proportional to the length of time it takes to remember.That is to say, the knowledge that took several years to learn can be remembered for a long time; while the knowledge memorized in a short period of time is easy to disappear from memory quickly.

Similarly, after repeated review, knowledge that took half a year to memorize will be difficult to forget at least in the next six months.

On the contrary, if you only use one night to remember a certain knowledge point and then ignore it, the memory of this knowledge can only last one night.Hugging the buddha's feet temporarily will end in forgetting everything overnight.This conclusion is also drawn from my own experience.

Some people may say: "I memorized it after memorizing it only once." However, if you observe carefully, you will find that the frequency of our recall of that knowledge is generally maintained at a certain level.Thinking of it is a kind of review in itself.Because of this, some knowledge is remembered firmly.

Section content:

Reviewing is very important.Reviewing ensures that knowledge is retained, and it also makes memory last longer.

Through review, associations can be strengthened

So why does reviewing make memories last longer?

There are two main reasons:

On the one hand, through repeated practice, you can subconsciously convey a signal to yourself - "this matter is very important".For example, just flipping through the English word book casually and repeating this simple practice can also form the understanding of "this is an important thing" in your subconscious mind.

On the other hand, association can be increased with the help of review.Strengthening while reviewing is the most effective association method found so far.Through review, we can also discover associations that have not been tried, thereby adding new associations.

The above two points show that our memory will last longer for knowledge that has been reviewed again and again.

If you don't review, you can't remember new knowledge

As a tutor, I strongly feel that many people rush forward without serious review.Before I could firmly remember the knowledge I learned last time, I wanted to write down a knowledge.

When I ask them why they do this, usually the answer is that remembering new things is more efficient.

However, please note that remembering new knowledge requires previous knowledge as a foundation.Only with the accumulation of previous knowledge can we better associate and remember new knowledge more easily.

Even so, there are still many people who do not review well, and forget the knowledge that has been memorized with great difficulty.If there are too many things forgotten, the association between knowledge will be incoherent, and new knowledge will not be easy to remember.

Only by reviewing old knowledge can we continue to learn new knowledge.Please review the knowledge you have learned until you are familiar with it.

The best time to review

No need to review when the memory is clear

Although the review is very important, it is not advisable to devote yourself to the review regardless of 21.Reviewing is about timing.

This is very similar to the sense of distance that is said in relationships.

For example, if you make a phone call every 5 minutes, even lovers will definitely find it annoying if you are not very excited.But if there is no contact for a long time, the two parties will become alienated.

A moderate sense of distance can create good interpersonal relationships.The same goes for memory.Although reviewing is very important, there is no need to review for no reason.Just remember it.Therefore, it is very important to find the timing of review.

For example, when the memorized knowledge is still clearly in our minds, we don't need to review it, because that's what we know.

On the other hand, if the interval between reviewing is too long, we may forget the knowledge we have memorized.If you start reviewing at that time, you still need to start from the beginning.From a time efficiency point of view, this is very unreasonable.

Section content:

Reviewing is about timing.

When memories start to get fuzzy, it's time to review

According to the different intensity, the timing of review can be divided into the following types.

Intensity 1:

It's too early to review.Reviewing before forgetting doesn't have much effect.

Intensity 2:

The perfect time to review.works well.

Intensity 3:

The review interval is a little longer.The effect of review is barely.

Intensity 4:

The interval between review is too long, and I have forgotten it.Every review has to start from scratch.

The best time to review is of course intensity 2.What kind of timing is this?That's when you just start to forget.

The knowledge memorized just now is something you can know, but as time goes by, the memory will gradually become blurred and eventually become something you won't know.

The best time to review comes when you just start to enter the ranks of things you don't know.

Do the first review immediately after memorizing

Seventy percent of it will be forgotten after a week

Just reviewing it once is not enough.It takes repeated review to make the memory firm.So, how often should you review?
