When we were young, we were able to quickly process information that entered the brain and were able to work accurately while performing tasks. If information processing speed decreases with age, work does not proceed as expected, and brain speed may feel slower compared to when we were young.
So, what kind of specific brain training should be done to increase the brain’s speed? First, by processing “symbols” such as numbers and letters as fast as possible has been found to activate the prefrontal cortex. For example, setting a time limit for brain training when solving simple calculations such as “4 + 3”, “8 – 2” as fast as possible and to also read as quick as possible. By having the consciousness to “calculate and read aloud” as fast as possible, the brain’s processing speed can be increased.
It may be easy to think that solving a difficult problem is equivalent to brain training, but in fact it is not because different parts of the brain work more quickly to tackle simple problems than to tackle difficult ones.
However, solving simple problems as quick as possible can be difficult for adults because as an individual grows older, they become less competitive and more careful not to make mistakes. For brain training, it is best not to worry about making mistakes, instead, what is important is the speed of solving problems.
Rather than asking for the correct answer, your brain’s information processing ability will increase further by working with “speed” for around 10-15 minutes every day.
