Short-Term and Long-Term Memory Loss

Memory is divided into three categories. These categories consist of: sensory memory, short term memory and long term memory, out of these short term memory is the main focus in this essay. It has been widely researched due to interest of how much memory can be stored, how long this memory can be stored for and what information is memorised.

After sensory memory, there is short-term memory or as some call it working memory. Here, memory is stored long enough to use it. When a task is needed to be completed, it is obtained here and may be quickly forgotten after the task is complete. Short-term memory and long-term memory can work back and forth. Information that is deemed important and to be remembered goes to long-term memory and when you need to remember something, it comes from your long-term memory and goes back to short-term memory. After it is used, it goes back to long-term memory to be recalled at a later time. Information that comes from sensory memory and is not forgotten

Memory is the process of encoding, storing and retrieving information in the brain. It plays an import role in our daily life. Without memory, we cannot reserve past experience, learn new things and plan for the future. Human memory is usually analogous to computer memory. While unlike computer memory, human memory is a cognitive system. It does not encode and store everything correctly as we want. As suggested by Zimbardo, Johnson and Weber (2006), human memory takes information and selectively converts it into meaningful patterns. When remembering, we reconstruct the incident as we think it was (p. 263). Sometimes our memory performance is incredibly accurate and reliable. But errors and mistakes are more commonly happen, because we do

The multi-store model of memory (eg, Atkinson and Shiffrin 1968) claims the memory can be sectioned into three distinctive parts: sensory store, short-term store (STM) and long-term store (LTM). Eysenck and Keane (2005:190) states that data is first encountered by the sensory store, then depending on the attention given, is processed to the STM and finally - if rehearsed - continues to the LTM.

Research has shown that there is “greater activation in the left inferior frontal and medial temporal lobes” (Stanford, 2006, p. 208) during the encoding of words which were later remembered as compared to those which were forgotten. The sensations perceived by sensory nerves are decoded in the hippocampus of the brain into a single experience (Mastin, 2010). The hippocampus analyses new information and compares and asssociates it with previously stored memory (Mastin, 2010). Human memory is associative in that new information can be remembered better if it can be associated to previously acquired, firmly consolidated information (Mastin, 2010). The various pieces of information are then stored in different parts of the brain (Mastin, 2010). Though the exact method by which this information is later identified and recalled has yet to be discovered, it is understood that ultra-short term sensory memory is converted into short term memory which can then later be consolidated into long term memory (Mastin, 2010).

Memory is a capacity that humans rely upon to relate to different events, experiences, conditions, and people. It is a vitally important process and system whereby the brain receives information from (external or internal) stimuli, stores it (encoding), and makes it available on a future occasion (retrieval). It provides continuity to people’s experiences across different periods of time.

Memory in the human brain is a complex process which is easier understood by the use of theoretical constructs. Memories begin as sensory stimuli which become sensory memory which only last about one second, from there it moves into working memory which lasts for about twenty to thirty seconds and is used to process information. Within working memory there are a few separate processes, the central executive which directs attention, the episodic buffer which is a secondary storage lasting ten to twenty seconds, this area communicates with long term memory as well as the central executive. The visuospatial sketchpad which is used to visualise visual and spacial

Human memory is a complex cognitive structure, which can be defined in many ways. One would argue that memory is 1.) The mental function of retaining information about stimuli, event, images, ideas, etc. after the original stimuli is no longer present. 2.) The hypothesized storage system in the mind that holds this information is so retained. A clear distinction is made between different types of memory systems and can be divided into subclasses.

There are many proposed divisions and sub-divisions of human memory, such as working memory, procedural memory, semantic memory or episodic memory. Many of the systems seem to overlap, with each having varying functions related to the maintenance of

The process by which the mind stores information for later use is called memory. For us to understand how memory works, we need to understand the process by which memories are formed. This process consists of three major stages; encoding, storage and retrieval. Firstly, in order to form new memories, information must first be converted into a usable form, this is called encoding. Once encoded, the information is then stored within the memory system, that can later be recovered or recalled to consciousness. This final stage is called retrieval.

Short Term Memory Loss. Ironically most of us don’t even think about memory that often, much less Short Term Memory. Because of that, this psychological disorder often tends to get overlooked for a small problem that no one wants to take serious. Most people would recognize this disorder from the popular movie, Finding Nemo. In which one of the main characters suffers from short term memory loss. In the film it’s taken as a lovable flaw, instead of the serious disorder that it is. But Short Term Memory is a lot more than one disorder found in a character in a movie. It is a somber disorder that could happen to any of us. This paper will be going through the gravity of this disorder and the causes to its victims.

In this system there are three separate components that combine to enable us to process memories. These three components of memory are sensory memory, short-term memory, and long-term memory (Reisberg, 2013). Of the three, sensory memory has the shortest time-span in our memory lasting roughly 300 milliseconds. The purpose of the sensory memory is to interpret the sensations coming to the body, and then transfer them to short term if there is enough attention placed on them (Reisberg, 2013). Short-term memory has a longer time-span in which it can be remembered. In short term memory we are able to remember 7 items +/- 2. These items can be remembered for up to a minute and that length of time can be increased if they are rehearsed. Rehearsal allows memories to be consolidated and be placed in long-term memory where they can be later retrieved and placed in working memory. Long term-memory are memories that can be retrieved with a hint or cue (Reisberg, 2013)

Second, short-term memory remains in the brain for a short period of time, maybe 25 seconds unless it is reiterated over and over again to be preserved longer in the

Memory- Long and short term both need to be examined. Short term memory impairment will result in difficulties in remembering and following directions. Long term memory can be examined by asking historical questions and short term memory can be examined by asking a patient to recall a series of words or numbers. There are optimal values that help determine whether or not a person has an impairment. This examination should take place because healthcare professionals need to know the current state of the person they are working with.

Memory is the process involved in retaining, retrieving and using information about stimuli, images, events, ideas and skills after the original information is no longer present. We can relate this case with what we learn in psychology. Short term memory holds information from 15 until 30 seconds whereas long term memory holds information for years. Short-term memory (STM) is the system that is involved in storing small amount of information for a brief period of time while long-term memory (LTM) is the system that is responsible for storing information for long periods of time and recall information about past events in lives and knowledge learned.
