Baddeley And Hitch Phonological Short Term Memory

10), an embedded approach, investigating the complexity of relationships of graphophonic knowledge. Additional activities to support phonics instruction include building word lists based on common elements (Pinnell & Fountas, 1998, p. 157), segmenting words into onset and rime (Emmitt et al, 2013, p.12) and the introduction of high frequency or sight words through modelling and sight words games such as flash cards, sentence strips, bingo, word shapes and extensive reading (Fellows & Oakley, 2010, p. 219) ensuring students reach a point of automaticity (Konza, 2016, p. 157), as sight words feature sounds that contradict the rules for learning the 44 phonemes and the point of automaticity allows higher-level comprehension processes to occur due to available cognitive

Outline and evaluate research in to the duration, capacity and encoding information in short term memory.

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

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.

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 the the…’ while reading a group of words. This repetitive task ties up the articulatory process and means you can’t rehearse the shorter words more quickly than the

Phonological and semantic lists can cause high, strong rates of false memories. Phonological false memories would peat in shorter durations of a presentation, but semantic false memory rates would start to increase with more spread out presentation times. It is also theorized that the semantic and phonological lists are similar with spreading activation, but the processing could differ when it was the speed and depth. Semantic false memory requires deeper conceptual processing for the semantic false memory to activate. Shallow perceptual activation of phonological lures decay faster than semantic activation. When other factors are constant for false recall rates, the rates for phonological and semantic lists are similar. The False recognition rates for phonological lists are lower than semantic lists by twenty to thirty percent.

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).

He conditioned a dog to make it drool at the ring of a bell. Normally

Burgess and Hitch (1999) added to and tested the original model of the phonological loop. They created multiple lists: one with the combination of short and long words, one with short words, and one with long words. Burgess and Hitch predicted that the short list would have a higher recall rate, while the long list would take longer to memorize. However, the mixed list would take less time to recall but longer time to memorize (Burgess & Hitch,1999).

Author used the example of doubling the short term memory to give a picture of how the improvement of human memory would be.

Baddeley (2001) suggests a working memory system which consists of four components; a modality-free central executive, a phonological loop which holds information in speech based form, a visuo-spatial sketchpad and an episodic buffer which is the temporary storage system that holds and integrates information from the phonological loop, visuo-spatial sketchpad and long-term memory (Eysenck & Keane, 2005).

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

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

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.
