The magic number 7 ± 2 The human brain can't hold more than it can, don't even try. But it loves numbers and blocks.
If you want to cram in more, it will still crush the information into logical groups.
Let's break down the strange number 7+/-2, which is 5 to a maximum of 9 objects easy to hold in memory.
These magic numbers were studied by psychologist George Miller in the 1950s.
You know, the human memory is not one, there are several kinds of memory.
by perception
by time
by type
by form
For example: you remember a telephone number or a surname and run to write it down.
After you have written it, you forget it. This is a short-term memory which contains the same numbers 7+-2.
Thus, short-term memory is a "purse" into which you can "put" seven "coins" at the same time. Moreover, memory does not try to analyze the meaning of information (what "coins" are in the "purse" - a dollar or a cent), the main thing is to have seven of them.
