Digital memory test: understand your short-term memory capacity

Digital Memory Test (Number Memoory) Test) is one of the most classic short-term memory assessment tools in cognitive science. By requiring the person surveyed to remember and repeat a series of figures, researchers can accurately measure the capacity and efficiency of the work memory.

Why is digital memory important?

In everyday life, digital memory is everywhere: remembering telephone numbers, bank card numbers, authentication codes, conference room numbers The size of the working memory capacity directly affects the efficiency of our information processing. Studies have shown that the work memory capacity is closely linked to learning achievement, problem resolution capacity, and reasoning.

Psychological background: the magic number 7

1956, George, psychologist Miller suggested in the famous paper Wonder Number Seven that the human short-term memory is about 7 ±2 information blocks. This means that most people can remember reliable numbers of 5 to 9 figures, on average about 7.

Modern cognitive science further revises this theory, considering the working memory capacity to be approximately four "blocks", but by organizing information into meaningful segments (i.e. "part-by-part strategy"), it can significantly expand the physical memory capacity.

How do you use this test?

Click "start testing" and a list of numbers will be shown on the screen.
Look closely at the numbers. The numbers disappear after the progress strip.
Enter the number sequence you remember in the input box
Right goes to the next level (digit + 1) and the error shows the final score.
As the level increases, the time shown will be reduced accordingly.

Skills for enhancing digital memory

Part memory method: The long series is divided into groups of 3-4-bit, such as "6274839102" as "6227-483-9102" in a similar telephone number format.

The Aide: Link numbers to specific images, stories or known information, such as "1234" in "1234 steps".

The Law of the Symphony: Add rhythm or melody to the numbers, which will be supplemented by the advantages of music.

Pattern discovery: Searches for patterns, equations, equations in the digital sequence, and uses the pattern instead of the dead back.

Recommendations for training

The two-to-four weeks of continuous training in digital memory, which is conducted 5-10 minutes a day, can significantly improve the work memory capacity. Memory is like muscle, it's getting stronger. In addition, adequate sleep, adequate exercise and reduced stress help to maintain optimal cognitive performance.
