Short-term memory
our initial memory store that is temporary and limited
Short-term memory is the type of memory that holds a small amount of information in our conscious mind for a short time, usually less than 30 seconds. It is also referred to as working memory, as it is responsible for holding information temporarily while it is being processed or manipulated. Examples of short-term memory include remembering a phone number while dialing, recalling the items on a grocery list while shopping, or retaining a new vocabulary word long enough to use it in a sentence.
The capacity of short-term memory is limited to about seven items, plus or minus two, according to George Miller’s famous “Magical Number Seven” theory. However, this capacity can be improved through attention, repetition, and the use of memory strategies, such as chunking or visualization.
The process of transferring information from short-term memory to long-term memory is critical for long-term retention and recall. Rehearsal, or the repetition of information, can help facilitate this transfer, as can meaningful associations and connections to already-existing knowledge.
In cases of memory loss or impairment, short-term memory can be disproportionately affected, leading to difficulties with daily tasks and routine activities. Strategies such as note-taking and external memory aids can be helpful for compensating for short-term memory deficits.
