Introduction

Consider the extent to which the working memory model is an improvement over the multi-store model. The working memory model was researched by Baddeley and Hitch in 1976, and is an improvement over the multi-store model of memory because it is more detailed, and therefore we can learn more about the stores of memory in the brain from it. The main weakness with the multi-store model of memory is that it is over simplified, as it implies that there are only two memory stores, one short-term and one long-term, and that memories are only stored through rehearsal, but this does not seem to be true in real life, as many memories are stored not having been consciously rehearsed. ...read more.

A study by McLeod in 1977 showed that two auditory tasks cannot be done fully at the same time, e.g. playing the piano and singing a song, this shows that the two tasks are competing in the auditory part of the brain, and helps us to understand that all auditory tasks are done in a certain part of the brain. The phonological loop has two parts to it, an articulatory process, (i.e. the process of speaking) and a phonological store, (which allows information to be rehearsed acoustically). Baddeley and Lewis (1981) found that articulatory suppression (a task which stops you speaking), did not affect decisions involving phonological differences, so showing that there must be a separate store. ...read more.

Conclusion

Another reason why the working memory model is an improvement on the multi-store model is because it only has rehearsal taking place in one area instead of it being the most important part as it is in the multi-store model. Also the working memory model supports the evidence we have from brain damaged patients, much better than the multi store model. Shallice and Warrington studied KF, who had a normal LTM, but a damaged STM. However his short term forgetting of auditory stimuli was much larger than his short term forgetting of visual stimuli, i.e. he was able to remember meaningful sounds, but not words. The working memory model is a big improvement over the multi store model, because it is in much more detail, and also has more evidence to support it. ...read more.

    Describe and evaluate the Multi-store Model of memory.

    According to Atkinson and Shiffrin, information was put into memory/ LTM through repetition. Craik and Lockhart proposed that it is the depth and processing, which is done that result in remembering information. There is evidence for Craik and Lockhart's theory that the deeper the processing the stronger and more durable the memory.

  2. SHORT TERM MEMORY

    very reliable result, as it shows the results are widely spread around the mean. This could also relate to the mean result collected for group 2 not very reliable and resulting in the standard deviation being widely spread out. The graph shows the mean averages of both group's sets of data.

  1. Investigating the short-term memory

    In both groups, the males were found to perform better at recall than the females in both groups. For group 1, the lowest number of words they were able to recall was 7, whereas for group 2 it was 5 words.

  2. How Valid is the Modal Model of Memory?

    The primacy effect is explained by the fact that the items at the beginning of the list stay in the buffer longer than latter items. As the buffer is empty at the beginning of the recall experiment, the initial items are not displaced by latter items until the buffer has reached its limited capacity.

  1. The Multistore model of memory

    P's asked to recall the whole grid, showed poorer recall (42%) whereas those asked to recall a row showed better recall (75%). This suggests how rapid decay happens in SS. 2. Glanzer & Cuntiz proved the existences of STM and LTM via the serial position effect.

  2. Outline and Evaluate the Multi Store Model of Memory and One Alternative Model

    However, when the subjects were delayed before repeating the list, this effect (the 'recency' effect) was lost. Atkinson and Shiffrin claimed that this was evidence to prove that the words at the end of the list remained in short-term memory, whilst those at the beginning had been lost due to decay.

    Therefore they were not displaced by other words. The reason the words in the middle portion were not as well recalled was because the increasing number of words entering the short term memory did not have enough time to be rehearsed and transferred to the long term memory, therefore it

  2. Alternatives to the multi store model of memory.

    Visual information is what things look like. Spatial information is about the position of objects in relation to each other. Logie suggested the VSSP can be divided in the visual cache which stores information about form and colour and the inner scribe which deals with spatial and movement information.
