Back when we were students and even at an age when we were just getting into society, we had a lot to learn from classes and work, and we stuffed our brains with new knowledge everyday. However, as we grow older, we work less and learn less as well, so the working area of ​​the brain that keeps memory tends to shrink and overall working memory to decline.
So, what kind of training is effective to increase the brain’s working memory and to expand its area? It is necessary to repeat training to temporarily “memorize” symbols such as letters and numbers. For example, there is a method by reciting the names of animals such as “rabbit, bunny, sheep, mouse” within a set time.
There is also a method called “n-back assignment”, which is to memorize numbers that are randomly arranged such as “1, 6, 8, 3, 7, 4, 2, 9” and answer “n numbers” before (n-back). For example, when asked for one number before “3”, it will require an answer of “8”. You can train your working memory by increasing the difficulty with “2 back” or even “3 back”.
This type of daily temporary training that focuses on memorizing increases the working area and improves working memory. People tend to think that “temporarily” knowledge has no effect on the brain, but to increase working memory, it is important to train the amount of information that can be temporarily stored in the brain.
Working memory training has been proven to be more effective than mental rotation training as it improves with daily training.
