Baddeley And Hitch Model Of Working Memory

448 Words2 Pages

In 1974, Baddeley and Hitch proposed a new model of working memory to expound upon the existing model of short term memory. Their initial framework was modular, with the temporary storage system components separate from long term memory. Recent research explores, both theoretically and experimentally, the connection of long-term language production knowledge on verbal working memory, specifically with immediate serial recall tasks. In section 2, I will first briefly introduce relevant aspects of Baddeley and Hitch’s influential model and also provide an overview of recent research articles exploring the connection of language production to verbal working memory. In section 3, I will discuss the details of the experiment for this proposal. Lastly, …show more content…

Baddeley (2012) discusses this model and how it has evolved over the years. He introduces the basic components of their initial framework, which consist of the central executive that controlled information flow to and from two separate temporary storage systems: the phonological loop and the visuo-spatial sketchpad. He explains that the phonological loop refers to a temporary store of verbal information that can be maintained through rehearsal. He found an improved memory span for words that produce a sentence over unrelated words indicating that the phonological loop interacts with outside systems. To account for this interaction, he added another component to his model that interacts with long term memory, which he called the episodic …show more content…

She argues that the divide in research between the language production and temporary verbal memory stems from serial recall tasks because recalling random words from a list is seen by researchers as separate from the long term knowledge needed to order words in a sentence, which she views as an immediate verbal memory task. To support her theory that there is a connection, she discusses several effects that occur in immediate serial recall tasks that also occur in speaking, such as the similarity effect, primacy effect, and list-length effect. This idea of behavioral similarity is also argued in another article. Acheson and MacDonald (2009) argue against verbal working memory being an isolated system and that the maintenance aspect of the phonological loop can be attributed to the serial ordering process of phonological encoding, which they define as “the process by which a word is specified as a sequence of phonemes for the purposes of articulation” (p.

Professor John Gabrieli and Michael Anderson, a psychology associate professor at the University of Oregon conducted the experiment. Where 24 people between the ages of 19 and 31 were given 36 pairs of nouns that were not related and asked to memorize them. After a few minutes they were able to remember them. This experiment was documented using a functional magnetic resonance imaging machine to view the brains processes. They were then asked to only remember the first words and forget the pairs while more scans were taken.

Adapting To Challenging Environments In A Long Walk To Water by Linda Sue Park, “Time Trip: Sudan’s Civil War” by Scholastic, Salva’s Bio” and “Water for South Sudan: Salva’s Story”, many events that happened in Sudan and how people adapted to their challenging environment are shown. The characters I will focus on are Salva, Nya, Salva’s Uncle, the Lost Boy’s, and Sudanese people in general. The main point I will focus on is that individuals adapt in challenging environments by taking small steps to complete a big task, moving from one place to another, and taking advantage of the current environment and it’s resources. The author uses several literary devices, including a plot, characters, images, language, and other things to show how Salva,

He defines this system as performing quick, automatic activities such as understanding simple language, recognizing ingrained phrases, and comprehending aspects of sensory stimuli. System 2, conversely, is the slow thinker, the logical one. System 2 is controllable, and “allocates attention to the effortful mental activities that demand it, including complex computations. He then proceeds to elaborate on these definitions and discuss the interactions between them. Hearing about this model for the mind for the first time, I found it greatly intriguing and full of great insight into how humans think.

The direct-access view explains that the state happens when memory quality is insufficient to review something, but rather is sufficiently solid to bring about the state. The inferential perspective claims that TOTs aren't entirely blocked off, yet set targets; instead they emerge when the person trying to remember tries to sort out diverse signs about the word. There are many explanations for the Tip-of-the Tongue, yet the cause of TOTs are unclear. These clarifications for the most part fall inside of the domains of direct-access view and the inferential

Evidence does suggest that the Phonological loop is made up of two components which are the phonological loop and the Articulatory Control process, the evidence suggests the phonological similarity effect, unattended speech effect, word length effect, articulatory suppression experiments and also including neuropsychological evidence. The Phonological store, is passive and also stores information in a coded form, the use in involuntary, as information decays in about two seconds if no rehearsal takes place, a small bugger for linguistic information. The phonological coding which would be the speech sounds, would be identical coding for

compared in congruent and incongruent wordlist Discussion J. R. Stroop (1935) in his study found that reaction time for reading words where colour is absent (words written in black ink), naming colours where words are absent, and reading words in colour had shorter reaction time than naming colours when words were present. My study, that was a condensed form of the Stroop experiment, got similar results. I found that reading words where colour is absent and reading words in colour have a significant difference. Reading words where colour is absent (condition 1) takes less time than condition 2; where the participant have to name the colour of the words. This indicates that there is a distinction between controlled and automatic processing.

The mental lexicon grows as we learn new words, and it is accessed every time we communicate, whether that be in the spoken mode or the written mode. A huge question that is asked by psycholinguists is: ‘how is the mental lexicon organised?’, and looking at Priming Experiments can help us to determine the answer to this question. Priming experiments are frequently used to find out more about the mental lexicon, in particular the

Additionally, the model is also supported by experimental evidence that is considerable, as the model was developed and based on evidence obtained from lab experiments, so confounding variables were able to be controlled in the lab, resulting in more accurate results. Working memory is also an effective theory in contrary to the Atkinson and Shiffrin multi-model store, as it can be applied to real-life tasks for example when reading something you have to utilise your phonological loop to process the words in the book. Additionally, when you 're performing a problem-solving task you have to utilise the central executive because you need to visualise the information you 're trying to solve, whilst using the phonological loop to process the letters or numbers. However, working memory model has its limitations as it is too simplistic and vague as it does not outline what the overall role of the central executive is. More so, there is also little evidence to support the central executive as it has never been measured.

Findings show that WF plays an extensive role in most of the AoA studies. To define, WF takes place if a word is frequently met. (*) Therefore often used in day-to-day life, (eg; clear frequent vs incisive not that frequent) input and output has to be constant by this means, hearing and processing of the word thus verbally communicating them. To sum up words which is actively present within the sample's overall mental dictionary will lead to faster RT in recall, in contrast to the words which are less frequently used (Morrison & Ellis, 1995) Furthermore AoA studies have been highly conducted in the past few decades.

At first working memory has been described as short-term memory and has been known as temporary, brief storage for latest experiences (Atkinson and Shiffrin ,1968). However, Alan Baddeley proposed that working memory is an active capacity proccessing stored information and linking it with long-term memory. He also suggested model of working memory with free component – visuospatial sketchpad, central executive and pchonological loop. (Baddeley and Hitch, 1974).

In essence, chunking is established as one of the mechanisms for human cognition process. It is crucial in explaining the relationship between the external environment and the internal cognitive processes (Reed, 2010). Empirical evidence in support of the relevance of chunking theory exists, especially in relation to the way that humans perceive words, paragraphs and words as single units, overshadowing their representation as comprising of collections of phonemes or letters. For example, the chunking theory explains how skilled readers have a tendency to be insensitive to deleted or repeated words. Studies that use information concerning timing of responses to ascertain the presence of chunks exemplifies evidence on the relevance of the chunking theory are particularly useful in understanding effectiveness.

If information stored in the short-term memory is not learned and given attention, it will decay over time (Schunk 2012, p. 183). The short-term memory has a small capacity, and large amounts of information cannot all be stored (Schunk 2012, p. 183). To make it esier, information can be shortened or broken up to fit it in the short-term memory (Schunk 2012, p. 183). Information that is used will be transferred into the long-term store/ long-term memory (Schunk 2012, p. 183). There are different strategies to strengthen the memory of information from short-term to long-term.

It was found that limits of the storage of the VWM processing may affect the way the words are being retrieved and may not be properly recalled. This might be the reason why recalling abstracts or elaborated sentences may be difficult to some. The limits to the experiment were that the sample taken had a great gender difference and the group was not demographically
