Comparing Working Memory And The Episodic Buffer

1. Comparing Working Memory And The Episodic Buffer
In 1974 the researchers Baddeley and Hitch argued that the picture of short–term memory (STM)
provided by the Multi–Store Model was far too simple. Following the Multi–Store Model, it is
believed that STM holds limited amounts of information for short periods of time with relatively
little processing, it is believed to be a unitary store. This means that due to its single store it has no
subsystems, unlike the Working Memory Model which has many subsystems. This proves that the
Working Memory is not a unitary store. Working Memory is STM. In contrast to the Multi–Store
Model, where all the information goes to one single store (Unitary store), there are different systems
for the different types of information. Working Memory consists of ... Show more content on

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.
Researchers such as Logie, Baddeley and Bunge generally agree that the short–term memory is
made up of a number of components or subsystems. The working memory model has replaced the
idea of a unitary store short–term memory as suggested by the multistore model. The working
memory model explains a lot more and in a lot more detail than the multistore model. It makes sense
a range of tasks– verbal reasoning, comprehension, reading, problem solving and visual and spatial
processing, it also applies to real life tasks such as reading which involves the phonological loop
subsystem, problem solving which involves the central executive and navigation which involves the

3. The Multi Store Model And The Working Memory Model
"Memory is our ability to encode, store,retain and subsequently recall information and past
experiences in the human brain" (Luke Mastin,2010). In this review I am going to focus on the multi
store model and the working memory model, which explain in detail how memory works.
The multi–store model (MSM) of memory by Atkinson and Shiffrin (1968), explains that the
memory is made up of three different stores.These are: sensory memory (SM), short term
memory(STM) and long term memory(LTM). This model explains how each store works in terms of
encoding, duration and capacity.
The SM obtains the information from environmental stimuli through our five senses which are
touch,sight,smell,taste and sound. In SM the encoding is either visual,auditory or haptic; duration is
¼ to ½ seconds and the capacity is all sensory experience(McLeod S.A,2007). Attention is essential
for the information to transfer to the STM, otherwise it is lost through decay. The information in the
STM is mostly encoded acoustically. The diagram below shows us how the information is
transferred from one store to another.
According to Miller 's Magic number 7 (1956) most adults can store from 5 to 9 items, therefore
STM is known to have a capacity of 7+/–2 items and a duration of up to 18 seconds. The
information in this store can be lost through displacement which is replacing the old information
with new ones or forgetting it (decay). There are two types of rehearsals. Maintenance rehearsal is
not effective

Cecilia Nguyen Evaluate two models of one cognitive process This essay will be discussing one
particular cognitive process: the memory by evaluating two models, which are the Multi store model
introduced by Atkinson and Shiffrin in 1968 and the Working memory model by Baddeley and
Hitch in 1974. The first model is the multi store model. It was first proposed by Atkinson and
Shiffrin in 1968 and is a typical example of the information–processing approach. According to this
model, memory consists of three types of memory stores: sensory stores, short–term store and long
term store. Sensory stores consist of the eyes, nose, fingers, tongue, etc and the corresponding area
of the brain. The sensory stores ... Show more content on Helpwriting.net ...
The visuo–spatial sketchpad when planned a spatial task and it saves memory temporarily. The
episodic buffer is the general store, it integrates info from the central executive, the phonological
loop and the visuo–spatial sketchpad and forms long term store. Research evidence for the working
model of memory varies. Case studies of brain damaged patients support this model a lot. The case
study of KF – a brain damaged patient with no problem with long term learning but some aspects of
his immediate memory were impaired. This has proven that the working model of memory was right
when suggesting that short term store works independently of long term store. In addition to
evidence supporting this model, Baddeley and Hitch did a research on making participants do two
tasks using the same or different components. Task one occupied the central executive, task two
either involved the articulatory loop or both the central executive and the articulatory loop. Speed on
task one was the same whether using the articulatory loop or no extra task. This shows that doing
two tasks that involve the same component causes difficulty. It also suggested that when two
different components are used, performance is not affected. Even though the working model of
memory is better than the multi store model, it still has some weaknesses. For example the role of
the central executive is vague and it needs more research. Also there were problems with

7. Action Video Games
The goal of this study was to determine if action video games (AVG) improved reading abilities and
visual–to–auditory attentional shifting in English–speaking children with dyslexia. Based on several

when action video games (AVG) were used. (Franceschini et al. 2017) However, a significant
variable was the difference in languages. This study wanted to determine would the same results

(Franceschini et al. 2017) The dual route model involves the grapheme–phoneme conversion,
requiring the serial left to right processing, thus causing the length of the words to determine the
time it takes to say them. The parallel processing has little to no effect based from the length or the
time taken to say the words. It is the length that generally has more effect on the pronunciation of
the words than the actual word itself. (Eysenck and Keane, 2015) In the text Jalbert et al. (2011)
found there was an important confounding between word length and orthographic neighbourhood.
(Eysenck and Keane, 2015) Like what the study was attempting to resolve, since the English
language is more orthographic than most languages.
Further, considering the systems of how dyslexics increase accuracy Paul et al. (1996) and Harm
and Seidenberg (2004) found the approach of the triangle model. This model focusing on this
disease know that the damage occurs mainly because of damage to the semantic system. This model
assumes phonological dyslexia is due to general impairment. (Eysenck and Keane, 2015)
Although, the text shows different theories that can relate to this study and how to better understand
the complexity, it is important to see that the increase in accuracy during reading from participants
increased with the assistance of AVG. During the study word reading was recorded, the time it took
the participants to pronounce the word correctly,

carried in conscious mental states is available to different cognitive processes. This is linked to

reaching towards fast–moving stimuli (Zeki and ffytche, 1998). Likewise, damage to the fusiform
face area causes prosopagnosia, although patients still demonstrate autonomic arousal when
presented with a familiar face (Pike and Edgar, 2010). These and other studies of altered function
following localised brain damage make ffytche (2000, as cited in Andrade, 2010) argue for the
modularity of consciousness. Beyond theory building, these examples are essential tools for the
study of the neural basis of visual awareness. Areas within the prefrontal, parietal and temporal
cortex are typically active during conscious processing (Logothetis, 1998).
Additionally, the relationship between attention and consciousness is an intimate one. Paying
attention brings objects to consciousness whilst they fade away once attention shifts. This is why
Naish (2010, p.59) states 'attention is the process which gives rise to conscious awareness'. The need
for attention in conscious processing is demonstrated in change blindness (changes in a viewed
scene are not detected, e.g. Simons and Levine, 1998) or inattentional blindness (not being able to
perceive things that are in plain sight, e.g. Simons and Chabris, 1999). Moreover, masking

17. The Theory Of Measuring Intelligence
Introduction
Since childhood I can remember how the term "IQ" could make or break a person's dignity and
credibility all in one. Through the years a line has been drawn that to this day categorizes a person's
abilities both mentally and physically. Statements like "He is street smart, not book smart" have
been used and overused in today's society. Although research and new learning strategies have been
in development since the 1980s, much of society still sees intelligence in this limited manner.
Though the course of this paper we will look at theories for measuring intelligence. We will also
explore how memory plays a major role in developing intelligence and the effect these factors have
on learning.

IQ and You
Intelligence is defined as "the ability to learn or understand or to deal with new or trying situations.
Other definitions include, "the skilled use of reason" and "the ability to apply knowledge to
manipulate one 's environment or to think abstractly as measured by objective criteria (Hacker,
2011)." One might ask, "How can one assume to measure intelligence with such a vague description
of what intelligence is?" Doesn't everyone have the ability to think and reason? The answer comes
in the latter part of the definition where a person needs to apply the knowledge learned. The way I
see it, intelligence applies to people in the following ways. One is the ability to learn new things;
another is the ability to think things through and the last is to apply learned content to life. The
problem with trying to measure intelligence is that it can never really be fully measured. If the
ability to apply learned knowledge is absent a real measurement cannot be achieved. This is where
the theory of I.Q. tests came into play. The letters I.Q. simply stand for intelligence quotient, which
is a phrase coined by Lewis Terman after his associate and him modified the original intelligence
test developed by Binet and Simon (Boyd & Bee, 2012). The theory behind the IQ test was to find a
way to measure the child's mental development based on the difference

19. The Atkinson And Shiffrin Modal Model Of Memory
Memory is a very crucial topic not everyone understands. We might hear an individual saying "He
has a great memory," or others mentioning they have a "bad memory" whenever they have forgotten
an important subject. People use the term memory frequently but often not knowing its true
meaning. According to Baddeley (1999), memory is not an actual organ as the heart, the kidneys, or
the liver; instead, it consists of a network in which many systems work together, allowing us to be
capable of remembering past events and in predicting the future. Reisberg (2013) presents the
Atkinson and Shiffrin Modal Model of Memory, in which they explained that when human body
receives an input, it is received as sensory information, which travels to our short–term memory
(also known as working memory) and is then processed to our long term memory (where it remains
permanently). According to Reisberg (2013) working memory includes conscious and active
processing of incoming auditory as well as visual–spatial information. It also retrieves information
stored from the long–term memory. In other words, it is the memory a person uses when actively
working on a specific task. Moreover, human working memory has a limited capacity; therefore,
there is a "magic" number 7 plus or minus 2, which demonstrates that the average capacity of words
that our working memory can store is 5 to 9 items (Reisberg, 2013). Baddeley developed a model
acknowledged as the Working Memory System. This model

21. Working Memory : The State Of Memory
Working Memory describes the state of memory we are actively engaged with. It performs the
functions of receiving, temporarily holding and manipulating information (Baddeley, 2010). To
assess memory psychologists have found it helpful to define their theories as models. Atkinson and
Shiffrin 's 1968 Stage Model of Memory defined 3 main components of memory systems; sensory
memory from perception of experience that becomes short–term memory (STM), which through
rehearsal loads more permanent connections as long term memory (LTM) (Andrade, 2001). Digit
span a test where a sequence of digits is heard and then repeated back, was often used to measure
the capacity of STM. The average people usually reach before error is 7 digits (Baddeley, ... Show

The primacy effect was thought to provide evidence of the rehearsal process that gets incoming
information from STM to LTM. (Andrade, 2001) Problems began to arise for the Stage Model of
Memory. Warrington and Shallice were studying patients in neuropsychology and found a patient
KF who had the reverse effects to HM of the ability to make long–term memories whereas his digit
span was around two (Andrade, 2001). It made Baddeley question the idea of STM feeding the
LTM. Further experiments of the recency effect and interference by Tzeng (1973) cited by Andrade
(2001) suggested there might be an alternative explanation other than STM disposition. Baddeley
and Hitch's Working Memory Model was published in 1974 in response to the limitations of the
Stage Model. The theory of Working Memory saw processing and storage contained in the present
activated memory (Andrade, 2001). Digit span interspersed with a simple comprehension task had
revealing results. The digit span of 1, 2 or 3 had hardly any impact on the accuracy or speed of the
comprehension task whereas 6 digits impacted in terms of slower speed but not as much as
predicted. (Baddeley 2010). Baddeley thought this showed that WM was capable of more than
verbal short–term storage and there must be at least another component that handled reasoning; the
central executive (Andrade, 2001). The WMM first comprised of 3 components, the central
executive controlling two sub systems, the phonological

Between the years 1990 and 2006, there was a 37,514 person increase in membership of the British

Research regarding the physiology of rock climbing has indicated the importance of taking climbing
style into consideration when making comparisons between studies (Sheel, 2004; Watts, 2004) due
to the different physiological effects on performance. Draper et al (2008) report onthat the

heart–rate and self–reported anxiety (CSAI–2R) were significantly higher for lead climbing (LC)
than for top–roping (TRC) . However, Draper et al (2008) offer no explanation for these findings.
Similarly, Hardy and Hutchinson, (2007) report that anxiety levels in beginner climbers were
significantly higher for their lead climb than in their top–rope ascent. It is now widely accepted that

25. Short Note On Short Term Memory Essay
When students are immersed in a situation where they are required to memorize a certain amount of
information in a limited period of time, students often use memory techniques in order to store a
given information. Most studies have suggested; students resort to using short–memory as a tool in a
last minute exam/quiz study session. Short–term memory is defined as a finite amount of
information that can be temporarily stored and retrieved for up to 20 seconds. Short–term memory
can also hold up to nine groups of stimuli in a given information (Weiten, Stalling, & Wasden,
2007). Models that have been used in the past demonstrate that short–term memory involves a
rehearsal loop: the process of repeating information by practicing either verbally or cognitively.
In Baddeley's (2001) model of working memory, he concluded that short–term memory involved
more than just a rehearsal loop. Baddeley's model involves: a central executive system, the given
undivided attention when needed; a visuospatial sketchpad, which allows individuals to store
visualized images; an episodic buffer, where working memory components are temporarily stored
up until retrieval; and a phonological loop, the process of repeating information by practicing either
verbally or cognitively.

According to Lloyd et al (1984) about 5% of all of a persons memories that are stored in their
sensory memory are transferred to their short–term memory.
The short–term memory allows a person to store the information for long enough for it to be used,
the short–term memory can also be called the working memory however this term later came to
have a different meaning. The short–term memory however only has a limited capacity to store
information; Miller (1956) claims that in order to save space in a person's short–term memory they
chunk information together but despite this space saving the short–term memory can only hold
seven plus or minus two of these chunks of information. According to Atkinson and Shiffrin (1971)
this information can be stored unaided for about 15–30 seconds, this time frame can be extended by
rehearsal.

29. Work Memory Analysis

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,

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

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

33. The Theoretical Framework Of Wm
Mrs. F is having difficulty following recipes while cooking as she is unable to mentally adjust the
amount of each ingredient called for in order to make only two portions. This is because of a deficit
in her memory, specifically her working memory (WM). While memory is defined as the "storage of
things learned and retained from an organism's activity or experience" (Merriam–Webster, 2015),
WM can be described as the cognitive systems that are required to temporarily store and manipulate
information (Baddeley, 2012). This report provides an overview of the theoretical multicomponent
WM framework as well as an in–depth look at one component of the framework, termed the
phonological loop (PL). Overview The theoretical framework of WM was introduced by Baddeley

that STM had three components, which was in contrast to the dominant model at the time (as stated
in Baddeley, 2010, 2012). To develop evidence to support their notion of multiple STM components,
they performed experiments, some of which used the methodology of functionally disabling parts of
participants ' STM systems by having them perform multiple memory tasks concurrently (Baddeley,
2012). After 26 years of experimentation a fourth component was added to the framework: the

Briefly, a behavior may result either in reinforcement, which increases the likelihood of the behavior
recurring, or punishment, which decreases the likelihood of the behavior recurring. It is important to
note that, a punishment is not considered to be applicable if it does not result in the reduction of the
behavior, and so the terms punishment and reinforcement are determined as a result of the actions.
Within this framework, behaviorists are particularly interested in measurable changes in behavior.
Educational approaches such as applied behavior analysis, curriculum based measurement, and
direct instruction have emerged from this model.[1]
[edit] Cognitivism
Main article: Cognitivism (psychology)
The earliest challenge to the behaviorists came in a publication in 1929 by Bode, a gestalt
psychologist. He criticized behaviorists for being too dependent on overt behavior to explain
learning. Gestalt psychologists proposed looking at the patterns rather than isolated events. Gestalt
views of learning have been incorporated into what have come to be labeled cognitive theories. Two
key assumptions underlie this cognitive approach: (1) that the memory system is an active organized
processor of information and (2) that prior knowledge plays an important role in learning. Cognitive

Discuss how memory can be explained with reference to models of memory and research into
Eyewitness Testimony. Introduction The investigation into memory – how we encode, store and
retrieve data – made great advances in the 20th century. Along with biological influences memories
define who we are, without them our individuality would be lost. This essay will scrutinize the
multi–store model of memory and working model of memory to determine their legitimacy. Each
model will be examined on its merits at how it explains cognitive functions. Through tools such as
the cognitive interview, eyewitness testimony has been deployed in countries around the world to
send millions to lengthy prison sentences. Despite its widespread use, the question remains: how
much can we trust someone's memory in the courtroom? Multi–Store Model of Memory 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
is substantial research backing this model. For example Murdock (1962) found the serial position
effect which shows when presented with a list of items, participants recalled those shown at the

39. Four Components Of Baddeley's Working Memory Model
People rely on incoming information and stored information to perform their everyday functions.
However, humans have a natural capacity of how much information they can attain. We are unable
to store all of our acquired information without different systems that organize our information.
Working memory is one of these systems that temporarily holds and manages information for
cognitive processing (119). Baddeley's working memory model is made up of four components that
allow for temporary information to be stored (109). The central executive directs the flow of
information. It functions more with delegating the way resources are used in cognitive tasks. The
central executive also coordinates information from the person's current environment with retrieval
of their prior information (119). The phonological loop is used to carry out rehearsed maintained
verbal material. It plays an important role in the acquisition of vocabulary, learning how to read, and
comprehending language. The visuospatial sketchpad maintains material through visualization. The
visuospatial sketchpad creates and manages our mental images. The episodic buffer is a temporary
system that connects information from long term memory to working memory. Mnemonic devices
are techniques people can use to help improve their ability to remember something. There are
various types of mnemonic devices people use to develop the associations. For example, the method
of loci relies on visualizing mental images

41. Human Memory: a Passive Mechanism or Dynamic System? Essay
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.
Research is increasingly concluding that the brain works as an integrated whole rather than a series
of discrete parts. In forming memory the brain passes information along the Papez circuit which
involves a number of regions of the brain. Brain research indicates that memory formation produces
physical changes to the way neurons are organized and ... Show more content on Helpwriting.net ...
(Gross et al.2000:16)Their research could however be said to support Atkinson and Shiffrin's (1968:
Ibid) theory of a separate store storage facility for STM and LTM.
Craik and Lockhart (1972: Ibid) examined how information is encoded once registered and
proposed the levels of processing theory, which focuses on the depth to which data is processed as a
means of improving retention. According to this theory encoding is carried out by a central
processor which can analyze stimulus on a shallow level, an intermediate acoustic level which
phonemic or phonetic in nature, and a deep semantic level, where the meaning is analyzed.
Craik and Tulving (1975, as cited in Gross et al. 2000:18) conducted an experiment whereby
participants were presented with a list of words and subsequently asked questions which required
them to process the data, shallowly, phonemically an semantically. There was a significant better
recognition of the word that had been processed semantically. While the LOP theory was the first to
propose that perception, attention and memory are all interrelated processes. It doesn't however
explain why semantic processing produces better recall, or definitively measure the so called 'depth'
of participants retention score.
Further examples of the significance of semantic processing and prior learning can be seen in the

Exploring the working memory
The multiple components model: A brief look at the history of the working memory can show a
graduate movement toward separate components of the memory. It can acknowledge that one of the
first models to separate the different components of working memory was the model modal
presented by Atkinson and Shiffrin (1968). They proposed that the short–term memory is a single
unity in which different stimuli modality is stored in one unit. This assumption encountered some
problems; one is that if the short–term memory were a single unit to all information modality, than
an individual with short term memory defect would be impaired in all cognitive tasks, which is not
the case in many short–term memory patients.
The multiple component of the working memory presented by Baddeley and Hitch (1974) gave a
reasonable conception as to how the short term memory function. Contrary to models presented by
Atkinson and Shiffrin who describe the short term memory as a single unity (1968) the working
memory model originally thought to be composed of three systems: the central enactive, the
phonological loop, the visuospatial sketchpad, and most recently, the episodic buffer. Each
component has a unique function that separates it from the other component. (Baddeley & Logie,

In executive category, tasks such as coordination, scheduling, planning, and working

executive processes take place in the frontal lobe. Frontal lobe syndrome shows difficulties in
concentration, organization, and proper behavior control due to damage to the frontal lobe. (Psych

Atkinson's and Shiffrin's (1968) multi–store model was extremely successful in terms of the amount
of research it generated. However, as a result of this research, it became apparent that there were a
number of problems with their ideas concerning the characteristics of short–term memory. Building
on this research, Baddeley and Hitch (1974) developed an alternative model of short–term memory
which they called working memory. Baddeley and Hitch (1974) argued that the picture of short–

It is helpful to think of it as the system that you use to mentally rehearse information by repeating it
over and over again4. And the Phonological Store (The Inner Ear – but not to be confused with the
canals in your actual ear) The phonological store uses a sound based code to store information, but
this information decays after about 2 seconds, unless it is rehearsed by the articulatory control
system. The phonological store receives its input either directly from the ears or from long term
memory. If you imagine your favourite piece of music you are using your phonological store.5 The
phonological loop explains why the word length effect occurs – the fact that people cope better with
short words than long words in working memory (short–term memory). It would appear that the
phonological loop holds the amount of information that you can say within 2 seconds (Baddeley et
al, 1975). This makes it hard to remember a list of long words such as 'anthropomorphic' and
'representative' compared to shorter words like 'walk' or 'again'. The longer can't be rehearsed on the
phonological loop because they don't fit (into the two second limit). But the word length effect goes
away if a person is given an articulatory suppression task, for instance if you are asked to say 'the

Short Term Memory: Related or Unrelated? Iris Medina California State University, Fullerton
ABSTRACT WILL GO HERE Short Term Memory: Related or Unrelated? Short term memory
(STM) is the second process in the ever so popular Information Processing Model and it is the area
where information is the most readily available, but also most susceptible to being forgotten
(Baddeley, 1986). STM has a very limited capacity, and can usually only hold so much information,
the magic formula for this being "7 +/– 2" (Insert source). The formula of plus or minus two, simply
stated is that humans STM's can only store five to nine items of information at a time. Research has
also shown that there is trace decay theory for items being STM, where items are easily forgotten
within seconds if they are not put through the articulatory loop (Baddeley, 1986). As described by
Baddeley, the articulatory loop is rehearsal of items that are currently stored in the STM. If items are
not mentally rehearsed, then they are lost. Baddeley was the first to coin the term articulatory loop,
but most researchers use it interchangeably with the term phonological loop. The phonological loop

The persons must then recall the items in the correct order in which they were shown. As mentioned
before, immediate serial recall has been the "holy grail" for theorizing about STM because the

this task. While Baddeley made it known that verbal items have to be mentally rehearsed in order

was supported by patient KF who had epilepsy, the doctor wanted to try and remedy this by
removing his hippocampus. This surgery was done, however instead of fixing his epilepsy, it
damaged his short term memory, yet he still had his long term memory intact. In the multi–store
model it states that in order to have long term memory, one needs to have gone through the several
stores, such as the sensory memory store, the short term memory and then by adding meaning and
rehearsal, into the long term memory store. Seen as patient KF could still encode long ... Show more

Another positive is the fact that it can be applied, or rather generalised to real life. For example in
job interviews when we talk, or when people text and drive, and it can cause us to crash. Finally
another strength of the working memory model is that is provides us an explanation for the brain
damaged patients KF and SC. As it shows us logical evidence that there is other stores in memory,
rather than the oversimplified view of the multi–store model. However, it does have its weakness,
one such weakness is its only address short term memory, not long term memory, and therefore it is
not a detailed model of memory, as it doesn 't address long term memory. Another weakness is the
circular argument, as it makes it difficult to find fault with the working memory mode. The circular
argument is that if two task cannot be done together, then it 's assumed that tis is because both of

detail. The 4 main components of the working memory model are; Central executive, Articulatory–
Phonological loop, Visuospatial sketchpad, and Episodic buffer.
The Central executive is the main component of Baddeley's working memory model and coordinates
the other two systems and ensures they don't go astray. It is also involved in directing attention and
resources towards tasks. Information is received from the senses or long–term memory and the

It also deals with cognitive tasks such as mental arithmetic and problem solving. The Phonological
loop consists of two parts; the phonological store & articulatory control process. The phonological
store, acts as an inner ear and holds information in speech–based form for one to two seconds.
Spoken words enter the store directly. Written words must first be converted into an articulatory
code before they can enter the phonological store. The articulatory control process, acts like an inner
voice rehearsing information from the phonological store. It circulates information round and round
like a tape loop. This is how we remember a telephone number we have just heard. If we keep
repeating it, we can retain the information in working memory. The articulatory control process also
converts written material into an articulatory code and transfers it to the phonological store. The

specific types of information. The visuospatial sketchpad component processes visual information

In order to understand a text the reader must be able to comprehend the vocabulary used in the piece
of writing. If the individual words don't make the sense then the overall story will not either.
Children can draw on their prior knowledge of vocabulary, but they also need to continually be
taught new words. The best vocabulary instruction occurs at the point of need. Parents and teachers
should pre–teach new words that a child will encounter in a text or aid her in understanding
unfamiliar words as she comes upon them in the writing. In addition to being able to understand
each distinct word in a text, the child also has to be able to put them together to develop an overall
conception of what it is trying to say. This is text comprehension. Text comprehension is much more

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.
According to Baddeley and ... Show more content on Helpwriting.net ...
This is interpreted as because the capacity of the phonological loop is limited in time (in Smith,

Further evidence for the existence of the phonological loop comes from Conrads and Hulls (1975 in
Passer, 2009) experiment in which they examined the effect of phonological similarity. They found
that serial recall in a list of similar sounding words tended to yield poorer results with participants
finding it difficult to remember compared to words that sounded different. It has also been found
that recall in semantically similar words tended to have little or no effect, supporting the idea that
verbal information is transferred in a phonological manner in working memory. In addition, Vallar
and Papagno (1995 in Smith, 2007) found that the phonological store in brain damaged patients
were dysfunctional.
Moreover, Hardyk and Petrinovich (1970 in Parkin, 1993) found the articulatory loop to be crucial
when being presented with complex information. In their study they measured participants throat
muscle and forearm muscle activity although some may argue that this was not a good technique to
carry out. Their findings led to them conclude that when participants were presented with complex

The phonological and the visuo– spatial sketchpad are known as the slave systems. The

is used to hold visual information; the eyes are used to store and manipulate visual and spatial
information such as remembering 3–D molecules or colour of solutions 5 6 7. All three–component

with sound or phonological information. The loop consists of two parts: a short term memory store
with auditory memory traces which can rapidly decay and an articulatory rehearsal component that

enters the phonological store. Information that is presented visually can be transformed into

73. The Foundation Of Interaction Hypothesis By Michael H. Long
Introduction Since the foundation of Interaction Hypothesis by Michael H. Long in 1983, there has
been a plethora of empirical research which has pointed to the benefits that L2 learning reaps from
conversational interaction (Keck, Iberri–Shea, Tracy–Ventura, & Wa–Mbaleka 2006; Li 2010;
Lyster & Saito, 2010; Mackey and Goo 2007; Russel and Spada 2006). Long (1981, 1983) asserted
that comprehensible input, although necessary, is not sufficient in the process of L2 learning, and
that through interaction learners notice the differences between their own formulation of the target
language and those of their conversational partners, which in turn may lead them modify their
output in order to make themselves understood. Mackey (2012) argues that Interaction often
involves the provision of feedback as interlocutors try to resolve the communication problems.
Feedback, according to Leeman (2007: 212), can be either positive confirming that the process of
communication has been successful, or negative, confirming that the process of conversation has
failed. Recast as a form of implicit corrective feedback has gained much saliency through research
(see for example Chaudron 1997, 1998). In support of recast, Long (1996) claims that input,
learner's internal cognitive processes, and output are all present in recast, thus providing the
opportunity for interaction–driven learning. Recasts provided on students' specific morphosyntactic
errors, namely question formation errors, have shown to

75. Working Memory Is A Cognitive System That Maintains And...
Working memory is a cognitive system that maintains and manipulates task–relevant information for
a short period of time. (Cowan, J. 1999) Memory plays a crucial role in everyday life. It enables one
to effectively perform complex tasks such as the ability to reason and solve new problems
independently on a daily basis. Working memory is limited in capacity and sensitive to
interruptions. "Without memory, our awareness would be confined to an external present and our
lives would be virtually devoid of meaning." (Schacter,D..L and Scarry,E 2001) Impairments in
working memory are often apparent in individuals with ADHD, acquired brain injury, depression
and several other conditions. It is important that researchers grasp an in–depth understanding of
what working memory is and how it works in order to develop interventions and ways to improve
working memory. Recent research has revealed that working memory can be enhanced through
Cogmed Working Memory Training. (Söderqvist,S. and Nutley, S. 2015) This essay will focus
predominantly on Baddeley's working memory model. It will outline the constituents of the model,
drawing upon evidence for and against the model. Atkinsons and Shiffrin's multistore model of
memory will be briefly mentioned. However, it is apparent that this model lacked detail and is
outdated.
Atkinson and Shriffin (1968) established a model known as the multi–store model. The model
depicts that memory can be interpreted as a sequence of steps, whereby

77. The Effects Of Age On Short Term Memory
The main goal of this study was to investigate the effects of age on short–term memory and to
examine if familiar music or unfamiliar music produced more errors in a word recall task. The
results showed that participants scored similarly in both the familiar music and the unfamiliar music
condition. The lack of a significant difference between the familiar music and the unfamiliar music
condition signifies that short–term memory is equally impacted while listening to familiar music as
it is when listening unfamiliar music. These findings oppose my original prediction that participants
would recall more words in the familiar music condition than they would in the unfamiliar familiar
music condition by showing that there was no difference in the average amount of words recalled
between the music conditions. It is possible that these results did not reach statistical significance
because, while the participants were familiar with the melody and lyrics of the song used in the
familiar music condition, they were unfamiliar with the specific version of the song. However, the
results replicated those of Alley and Greene (2008), which also showed that music familiarity had no
impact on short–term music performance. The results also revealed that the older participants and
younger participants performed equally as well on the recall task. Fascinatingly, this result suggests
that age has little relevance on the immediate recall of words. The implication of this finding is
unexpected
