Let's try thinking about "memory." First, please try playing the game at the following link. The rules are simple: memorize the numbers that appear momentarily, then click to answer. Free Working Memory Tests [https://www.memorylosstest.com/free-working-memory-tests-online/]

 

How did you do?

 

The human brain has two types of memory: "short-term memory" and "long-term memory." This game is a test of short-term memory. Short-term memory is also known as "working memory," and refers to memories that are stored temporarily in the brain.

 

According to research conducted by Princeton University psychologist George Miller, short-term memory is retained for only about 20 seconds. After that period of time, it is considered unnecessary and forgotten. Try to answer the questions in the previous game 20 seconds after you see the numbers. It should be much more difficult for you to do so.

 

We can expect to achieve increased efficiency in language learning if we understand and utilize this characteristic of memory.

 

In fact, George Miller made another important discovery: the fact that “humans can only commit 7±2 pieces of information to memory at a time." In other words, we are able to memorize 5–9 pieces of information. This is known as the “magical number”.

 

Up until now, many people have been tested to see how many digits they can remember, and there are almost none who can remember more than 9 digits. This seems to be the limit of human beings.

 

So, how can we remember an 11-digit phone number? We can do this because we use a method known as chunking. For example, we can divide the phone number 08012345678 into 3 groups, "080," "1234," and "5678," and memorize them as 3 pieces of information. By doing so, we can get around the short-term memory limit of 7±2 pieces of information at a time.

Put another way, a person can only memorize 7±2 "chunks of information" at a time. By applying this knowledge, we can make it easier to memorize longer English sentences for English presentations, and so on. For example, the sentence "I object to the idea that classical music and popular music should be dealt with as totally different categories." can be divided into the following groups:

 

"I object to the idea"

"that classical music and popular music"

"should be dealt with"

"as totally different categories."

 

It is easier to memorize sentences by dividing them into groups in the manner shown.
