Most Effective Long Term Memory Strategy

Most Effective Long Term Memory Strategy

One of the most common problems with students is that they have a hard time memorizing. A lot of students grumble that even they studied they forget it within a month, week or sometimes a day. That’s because they put the information to the short term memory. The human brain can retrieve only what stored in the long term memory. So the strategy of every student should be putting information(what they are studying) to the long term memory.

In psychology, it called ESR method or sometimes revision theory. It’s the most simple, common but most effective way to put information into the long term memory.

Before we reveal the method you should have a basic idea about memory and how it behaves. After that, we’ll get into the method.

There are 3 types of memory

  1. Sensory Memory
  2. Short Term Memory
  3. Long Term Memory

Sensory Memory

Sensory memory only lasts about 25 seconds. Most of the information that comes through our eyes, ears, nose, mouth, and skin only lives 25 seconds in our memory. It called sensory memory.

Short Term Memory

If we try to memorize what in the sensory memory by repeating, saying out loud or any necessary way it goes to short term memory. Short term memory lasts about 30-40 minutes.

Long Term Memory

If we repeat again and again or visualize what in the short term memory, it goes to the long term memory. Theoretically, Long term memory could last a lifetime.

This method is known as the ESR Memory model. ESR represents,

  • E- Encoding
  • S- Storing
  • R- Retrieving


Encoding is the process of information getting into your memory. When you are studying, attending a lecture, reading books or listening is basically what encoding is.


When you are encoding, the information stored in your memory and information stored in all 3 memory types(sensory, short term, and long term). Approximately 70% in short term memory and 30% in the long term memory.


It’s the process of getting information back. It’s the ability to recollect information once we stored in the memory. But the human brain only can retrieve what’s stored in the long term memory. So if we study a particular subject once, the average human mind can retrieve only about 30% on that subject.

Revision Theory

Revision theory shows that if we encode the same subject again, our storing percentage and retrieving percentage goes higher and higher.

Approximately if we repeat once it goes to 60% retrieval rate. If we repeat it goes to 90% and it can go to 120% if we repeat for the 4th time.

You may wonder how can we get 120%? 100% is the maximum possible retrieval rate. It’s “intuition” that comes by repeating the same thing. That’s how you get the creativity that didn’t exist before. If you look at the scientists, celebrity artists, high performing athletes, history makers they all master their craft for a long time. Longevity is the path to genius.

How the method works

As I mentioned before it’s really simple and common. You have to repeat ESR again and again until you are capable of having intuition and creativity in that particular subject. Yes, it may take time than usual a study but it’s far more productive and efficient. Because you are putting information to the long term memory that has the potential to last a lifetime.

If you have trouble with encoding and storing there’s also a method for that. The Feynman Technique is the best way to learn anything from my experience.

Hope you all benefit from the methods and triumph in your exams
