Introduction
The working memory aids our ability to remember words over non-words, specifically the phonological loop and visuospatial sketchpad (Baddeley, Hitch, 1994). Other studies by (Paivio, 1991) have shown that concrete words are easier to recall than abstract words due to semantic associations. The purpose of this paper is to explore the parts of memory that help certain words to be more easily remembered than others. Memory is the system that enables us to learn skills and gain information through sensory memory and short-term storage. It is also the process that allows us to retrieve this information from long-term storage (Baddeley, 1974). Being able to create a new memory, put that memory away in storage, and bring it back when

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) Their are two components of long-term memory, declarative and non-declarative memories. Declarative memories consist of items that we are consciously aware of. Declarative memories break into two categories, semantic which are factual memories, and episodic which are memories from experiences. Non-declarative memories are memories that are processed without conscious awareness, it often …show more content…
They proposed the phonological loop had evolved for language acquisition and storage. Also their study found that the ability to pronounce a word places it in phonological storage, allowing you to recall the memory quicker (Baddeley, 1994). The phonological loop has been found to be a workspace for verbal information (Baddeley, 1994). Other studies have also found that the phonological loop works to process auditory information as well (Reisberg, 2013). The visuospatial sketchpad, (Baddeley, 1994) was used to recall a visual object. In the visuospatial sketchpad images are placed on different spatial maps, which then tied together with the spatial workspace on the visuospatial sketchpad. The decision maker of working memory is the central executive. It decides which memories are retrieved, what information you should focus on, how important the information is, and how to attain goals (Riesberg, 2013). Without the central executive, our thoughts and actions would be unorganized in our working memory (Riesberg, 2013). In order to reduce the workload of the central executive, and allow it to focus towards important tasks, the episodic buffer works to store the information gathered from the visuospatial sketchpad and phonological loop (Baddeley, 1974). These models of memory show us how it is organized and operates, and there are other models of memory that go into how memory aids our
This supports the idea of an immediate memory store for items that are neither visual nor phonological and that draw on long-term memory to link the related words. It is used as both the Phonological Loop and the Visuo-Spatial Sketch Pad have specific roles and the Central Executive has very limited storage capacity so as a result there was no where to store both visual and acoustic information. The Episodic Buffer is an extra storage system that has in common with all working memory units, a limited capacity. It is handy and can integrate information from the Central Executive, The Phonological Loop, The Visuo-Spatial Sketch Pad and also information from the Long-Term Memory.
The slave systems consist of the Phonological loop and the visio spatial sketch pad. These are responsible for storing different types of data which the central executive allocates. The central executive is the main system in the working memory model. It controls attention and allocates data to the two slave systems.
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.
Some scientists believe that parts of long term memory are permanent while others will eventually weaken over time. (3) Long term memory can be divided into three sections: procedural memory, declarative memory, and remote memory. Procedural memory includes motor skills such as learning how to ride a bike or how to drive a car. "Such memories are slow to acquire but more resistant to change or loss." (4) Declarative memory is used to remember facts, such as names, dates and places. It is easy to learn but also easy to lose. Finally there is episodic memory, which is the record of events that a person stores throughout his or her experience. Recent studies show that these events, as soon as they occur, are sent to a temporary part of the brain called the hippocampus, and that over time they are moved to the neocortex for permanent storage. (5).
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).
Working memory's current understanding largely stems from the model in 1974 by Baddeley and Hitch, since then it has been recently advanced. The boss being the central executive, who controls and monitors all the information processing. The two other separate storage systems that support the central executive: phonological loop, who functions as the temporarily store for phonological information, and the visuospatial sketchpad where visual and spatial representations are temporarily stored and manipulated (Baddeley, 1996). The integrator of information from the subcomponents of working memory and long term memory is known as the episodic buffer, it is the recently proposed addition (Baddeley, 2000). Many people when they think of an individual
This essay addresses the working memory model which was proposed by Baddeley and Hitch (1974 in Smith & Kosslyn, 2007) as a response to Atkinson and Shiffrins (1968 in Smith, 2007) multi-store model. According to Baddely and Hitch the multi-store model failed to explain most of the complexities of the human memory and viewed it as being too simplistic. They argued that the short term memory store must have more components rather it being a single inflexible store as suggested previously by Atkinson and Shiffrin (1968). The working memory model is therefore an enhancement of the multi store model. According to Baddeley and Hitch working memory is a limited- capacity system that stores and processes information.
As for the evidence of the working memory system, two British researches, Alan Baddley and Graham Hitch, have proposed a model in how to explain the working memory system. They have suggested that the system contains many different parts, and that the main working part of the system is the central executive. This central part is able to delegate tasks for the low-level “assistants” to handle, since these assistants are not able to actually analyze a situation on their own. The articulatory rehearsal loop is one of the assistances that allows a person to remember, and is the most beneficial in many ways. This assistant allows you to recall information that is previously stated by repetitively stating the information in our head, which is known as subvolcalization, or silent speech. Furthermore, Baddley and Hitch’s model suggest that we are able to see the existence of this working memory through “sound-alike” errors, because our bodies rely on this rehearsal loop or memory to recall information. In a study, there was a control group which was given a normal digit-span test. In the other group, people were asked to perform concurrent articulation when they took the test. Although this concurrent articulation is not difficult, it does affect the use of the articulatory loop and decreases the memory. With that being said, manipulation of a
“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.
In the last half century several theories have emerged with regard to the best model for human memory. In each of these models there was a specific way to help people recall words and
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.
To begin with memory like everything else in the body there is a process that occurs; first it goes through "encoding, storage, and retrieval."(This is the process of memory, each are very important and it is amazing how the brain deciphers what is going to stay in the long term memory or short term. First off is encoding, it is all about "sensory information into
The generally accepted classification of memory is based on how long you can remember an item or experience (memory retention), and identifies three types of memory: sensory memory, short-term memory, and long-term memory
Memory is defined as "the persistence of learning over time through the storage and retrieval of information." Our memory can be compared to a computer's information processing system. To remember an event we need to get information into our brain which is encoding, store the information and then be able to retrieve it. The three-stage processing model of Richard Atkinson and Richard Shiffrin suggests that we record information that we want to remember first as a fleeting sensory memory and then it is processed into a short term memory bin where we encode it ( pay attention to encode important or novel stimuli) for long-term memory and later retrieval. The premise for the three step process is that we are unable to focus on too much
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
