Memory And Sensory Memory

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.

“Information flows from the outside world through our sight, hearing smelling, tasting and touch sensors. Memory is simply ways we store and recall things we 've sensed.” When we recall memories, the original neuron path that we used to sense the experience that we are recalling is refined, and the connection is made stronger. Sensory information in stored for only a few seconds in the cortex of the brain. This information can then progress to short-term memory, and then long-term memory, depending on the importance of the information received.

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.

There are 3 necessary steps/types that are crucial to forming a lasting memory. Step 1: sensory memory, step 2: short-term memory, and step 3: long-term memory. These are the three types of memory that are needed to build a lasting memory. Sensory memory is the shortest memory in the shortest- term memory element.One of the types of memory allows you to remember information through the 5 senses. The brain will remember anything that happened from 1 second to 60 seconds using the sensory part of your memory. An example of sensory memory is: I got hit in the head with a purple yo-yo. After sensory memory comes the short-term memory. Short-term memory acts as a “scratch- pad” for temporary recall. Short- term memory holds small amounts of information. Anything something that took place in front of your eyes for longer than 60 seconds, the short-term memory section of the brain will remember it. This section of your brain will allow you to recall that information in the next few hours or days. An example of short-term memory is: time on the clock 10 minutes ago. Lastly, comes long– term memory. Long- term memory, is used to store information of a set time

Scientist recognize 3 types of memory storage. Sensory memory which I found out last just a few seconds, short term memory, working memory and very important one, long term memory.

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).

McLeod (2007) describes memory as the psychological function of processing & preserving vast amounts of information such as visual images, acoustic sounds and semantic meanings. According to the Oxford Dictionary of Psychology (2009), memory involves a series of interconnected systems that serve different functions. The basic divisions of these systems are declarative and procedural memory, episodic and semantic memory and long and short term memory.

Stimulus Discrimination • The tendency of a CR to be weaker or not occur to the CSs that are dissimilar to the original CS or that have undergone extinction. Classical conditioning • Establishing a learned association between two stimuli. (Pavlov and dogs) Operant Conditioning • The imposition of a contingencies, either deliberate or natural. (reinforcer and punisher) Little Albert Experiment • Watson and Rayner 1920 • When presented with a white rat, a disturbing noise. Became afraid of other white colored things (white dogs, fur coats, santa claus) Negative reinforcement • Something unpleasant is moved away or doesn’t happen when the desired behavior is performed. Chapter 5: Acoustic encoding • The process of remembering and comprehending something that you hear. Repetition of words or putting information into a song or rhythm uses acoustic encoding. Semantic encoding • A specific type of encoding in which the meaning of something (a word, phrase, picture, event, whatever) is encoded as opposed to the sound or vision of it. Research suggests that we have better memory for things we associate meaning to and store using semantic encoding. Iconic encoding • Very brief sensory memory of some visual stimuli, that occur in the form of mental pictures. Stored for shorter periods of time than echoic memories. Memory retrieval • The process of extracting knowledge fro long term memory. Curve of forgetting • The

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

7). The Sensory memory could be compared to a sorting table of information. Everything collected by our senses from the environment around us is dumped onto a sorting table known as Sensory Memory. This information does not stay there long, only a few seconds before it is saved into our short-term memory if it is valuable or discarded if it is not. Once in the short-term memory the information needs to be repeated to be remembered and moved into the long-term memory. This process is known as memory consolidation, rehearsal or consciously repeating information is a requirement for long-term memory retention. Otherwise, the information is lost after twenty seconds in the short-term memory. The long-term memory is limitless in its capacity to store information, it holds memories from just a few minutes ago, to years and years ago. As an example, if I were studying for a mid-term exam, I would use a three-step process to retain the information. First, I would read the information start to finish, highlighting information I found interesting or pertinent to lessons objectives. Thus, I am taking the information in though my sensory memory and recognizing that I want to retain it. Second within the twenty seconds the information is in my short-term memory I repeat the information by highlighting it. Thus, through rehearsal the information is consolidated and moved into long term memory. Lastly, I would put the information on flash cards using my own words, for more repetition, to assist me in the recognition and recall of the information during the

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.

Sensory memories are momentary recordings of information in our sensory systems. They are memories evoked through a person's five senses: sight, smell, sound, taste, and touch. Although sensory memory is very brief, different sensory memories last for different amounts of time. Iconic

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)

In general, there are three types of memory: sensory memory, short-term memory and long-term memory. Sensory memory, by definition, is the preservation of information in its original sensory form, for a fraction of a second. This means that when you smell, touch and/or see anything, the impression of the occurrence will last for a couple of moments. This

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.
