Medical Definition of Short-term memory

Short-term memory: A system used to temporarily store and manage the information necessary to perform complex cognitive tasks such as learning, reasoning, understanding and so on. Short-term storage includes selection, start and end of information processing functions such as data encoding, storage and retrieval.

One test of short-term memory is the storage period, the number of items that a person can grasp and be remembered, usually a word or number. In a typical memory span test, an inspector reads a list of random numbers at a rate of about one digit every second. At the end of the sequence, subjects need to call the project in order.

Since we have technology, let's talk about two memories: long-term memory and work memory. You may have heard about long-term memory and short-term memory, but cognitive psychologists call short-term memory "working memory". There is a difference in the concept of short-term memory and working memory, but these two are exchangeable for non-experts. Working memory acts as a "scratch pad" for processing information. Work memory is the place where thinking is done. Working memory retrieves information by retrieving information from the outside world or long term memory and considering it. Working memory has three important things: it has limited capacity for a limited period, and is very unstable.

Memory has several different kinds: emotion, short term, work, and long term. As long as we do not pay attention to it, the memories are short. Short term memory can serve as a temporary storage tank for what we truly care about, but it has limited storage capacity. Interference often destroys short-term memory. Working memory is also a limited area, but you can store and save information as you process and infer various steps. Long-term memory lasting more than 30 seconds is either declarative (including facts and events gained through conscious recall), semantics (context-independent), or sentimental (highly contextualized). Because this complex process involves all parts of the brain, depending on the type of memory, the emotional content, and the perception, processing, and analysis necessary for memory, any area of ​​the brain is completely responsible for memory I do not.
