What to know about short-term memory and short-term memory loss. Medically reviewed by Seunggu Han, M. Definition Short-term memory loss Causes of short-term memory loss Psychological causes Treatment Improving short-term memory Contacting a doctor Summary Short-term memory refers to information that people can remember for a short period of time immediately after receiving it. Saul McLeod , published Short-term memory STM is the second stage of the multi-store memory model proposed by the Atkinson-Shiffrin.
The duration of STM seems to be between 15 and 30 seconds, and the capacity about 7 items. The Magic number 7 plus or minus two provides evidence for the capacity of short term memory. Most adults can store between 5 and 9 items in their short-term memory.
This idea was put forward by Miller and he called it the magic number 7. He found out that people find it easier to recall numbers rather than letters. The average span for letters was 7. The duration of short term memory seems to be between 15 and 30 seconds, according to Atkinson and Shiffrin Items can be kept in short term memory by repeating them verbally acoustic encoding , a process known as rehearsal.
Using a technique called the Brown-Peterson technique which prevents the possibility of retrieval by having participants count backwards in 3s. For example, it will take a large amount of effort to memorize the following number: 65,,, However, it will be easier to remember if it is chunked into the following: Easily remembered mnemonic phrases, abbreviations, or rhymes can help move short-term memories into long-term storage.
A few common examples include:. Another mnemonic strategy, which dates back to around BCE, is the method of loci. The method of loci involves mentally placing the items you are trying to learn or remember around a room—such as on the sofa, next to a plant, or on the window seat. To trigger your memory, you then visualize yourself going to each location, triggering your recall for that information. Memory consolidation is the process where our brains convert short-term memories into long-term ones.
Rehearsing or recalling information over and over again creates structural changes in the brain that strengthen neural networks. The repeated firing of two neurons makes it more likely that they will repeat that firing again in the future. For most of us, it's pretty common to occasionally experience an episode of memory loss. We may miss a monthly payment, forget the date, lose our keys, or have trouble finding the right word to use from time to time.
Still, if you feel like you're constantly forgetting things, it can be irritating, frustrating, and even cause fear that we're "losing it" or getting Alzheimer's. Short-term memory loss may even make you worried that your brain is too reliant on devices like your smart phone rather than your memory to recall information.
However, mild memory loss doesn't always indicate a problem, and certain memory changes are a normal part of aging. Short-term memory loss can also be caused by other, non-permanent factors, including:.
Short-term memory plays a vital role in shaping our ability to function in the world around us, but it is limited in terms of both capacity and duration.
Disease and injury as well as increasing reliance on smartphones can also have an influence on the ability to store short-term memories as well as convert them into long-term memories. As researchers continue to learn more about factors that influence memory, new ways of enhancing and protecting short-term memory may continue to emerge. In the meantime, if you have had trouble remembering things lately, talk to your healthcare provider.
They can give you a thorough exam to determine what might be causing your symptoms and recommend appropriate lifestyle changes, strategies, or treatments to improve your short-term memory.
