Short-term memory acts as a filter and temporary storage.
It is often used interchangeably with short-term memory.
I has been theorised that a human brain can retain 5-9 elements in short-term memory. An incorrect application of this theory would be to limit the number of items on a website navigation menu to 9 items. It would also be unreasonable to limit the number of items on a drop down menu within a computer application for this reason. This limiting of items on menus is not necessary because menus lend towards recognition rather than recall.
The term “short-term memory” came first.
Long-term memory stores items "permanently". This can happen due to repetition or rehearsal of the information with the goal of retaining it for an extended period of time, longer than is possible with short-term memory.

Improve your short-term memory by 1) boosting your brain health with the right diet, supplements, and lifestyle, and 2) using memory techniques to develop it.

The type or characteristics of the information also affects the number of items which can be retained in short-term memory. For instance, more words can be recalled if they are shorter or more commonly used words, or if they are phonologically similar in sound, or if they are taken from a single semantic category (such as sports, for example) rather than from different categories, etc. There is also some evidence that short-term memory capacity and duration is increased if the words or digits are articulated aloud instead of being read sub-vocally (in the head).
