Short-term memory could be defined as the memory mechanism that allows us to retain a certain amount of information over a short period of time.
Short-term memory temporarily retains processed information that either fades quickly or turns into long-term memory. Short-term memory has two main properties: Short-term memory acts like an access door to long-term memory , or like a storage room that makes it possible to retain information that we won't necessarily need in the future, but that we need in the moment. As short-term memory is directly related to long-term memory, any damage to short-term memory can affect the acquisition of new memories into long-term memory.
If short-term memory alone is damaged, we lose the ability to retain information over a short period of time. This would make it very difficult, or even impossible, to understand long sentences and and follow along in a conversation. When we talk about memory, it is normal to think about memories and experiences, but memory is involved in many other processes.
In general, it is possible to distinguish between four memory mechanisms that are relatively independent from each other:. Information can pass through various different stages on its way to either being stored or forgotten: We perceive the information that is received by sensory memory senses.
From there, our short-term memory retains the information over a short period of time. The information may be manipulated organized. Here is where long-term memory intervenes. This step does not always occur. In the last stage, the brain must decide whether or not the information is relevant and should be remembered, or if it is irrelevant and should be forgotten.
If the information is important, the memory will be passed on to long-term memory. If short-term memory is damaged, the systems that depend on it will be altered , like working memory and long-term memory. If you are not able to retain information from short-term memory, operative working memory will not able to properly manipulate this information. With respect to long-term memory, new memories will be affected, as the information passed from short-term memory to long-term memory will be altered.
However, it is possible to recover memories previously stored in long-term memory. If the different types of memory weren't independent, all of the systems would fail if one of the types of memory was damaged or altered. Luckily, the brain dedicates different areas to different types of memory, which means that an alteration in long-term memory won't affect short-term memory. In general, all of the different types of memory work together, and it would be difficult to find the point where one type of memory ends and another begins.
However, when one of them is damaged, the brain is unable to do its job and suffers significantly when performing day-to-day tasks. An alteration in short-term memory can affect both how long information is held, as well as the amount of information that is retained. In the case of a mild alteration, the amount of time that the information is retained may be affected, which would be considered a "little visible" damage retain information 15 seconds rather than However, a severe alteration may almost completely destroy the mechanism of short-term memory.
Short-term memory can be damaged in a variety of ways. As we mentioned earlier, it is altered in the early stages of Alzheimer's Disease , along with long-term memory. Short-term memory has also been shown to play a role in dyslexia , as the difficulty to store phonological information may lead to problems learning to read. Consuming excess marijuana is another factor that has shown to affect short-term memory, as well as brain damage due to stroke or brain trauma. Short-term memory plays a large role in the majority of daily activities.
Our ability to appropriately interact with our environment and the people that surround us depends directly on short-term memory. This is one of the reasons why evaluating your short-term memory and knowing your cognitive level can be helpful in a variety of different areas: Academic - will help you understand if a child has trouble learning to read or understanding long or complex sentences. Professional - short-term memory can serve as an indicator of how easily a worker will internalize and work with complex orders.
Aside from short-term memory, these tests also measure spatial perception, processing speed, and working memory.
Learn to play a musical instrument. Volunteer at a local school or community organization. Social interaction helps ward off depression and stress, both of which can contribute to memory loss.
Look for opportunities to get together with loved ones, friends and others — especially if you live alone. You're more likely to forget things if your home is cluttered and your notes are in disarray. Jot down tasks, appointments and other events in a special notebook, calendar or electronic planner.
You might even repeat each entry out loud as you jot it down to help cement it in your memory. Keep to-do lists current and check off items you've completed. Set aside a place for your wallet, keys, glasses and other essentials. Limit distractions and don't do too many things at once. If you focus on the information that you're trying to retain, you're more likely to recall it later.
It might also help to connect what you're trying to retain to a favorite song or another familiar concept. Sleep plays an important role in helping you consolidate your memories, so you can recall them down the road. Make getting enough sleep a priority. Most adults need seven to nine hours of sleep a day. A healthy diet might be as good for your brain as it is for your heart. Eat fruits, vegetables and whole grains.
