Outline and evaluate the multi-store memory model

Introduction

´╗┐Outline And Evaluate The Multi-Store Model The multi-store model of memory is an explanation of how the memory processes information. There are two memory stores within this model; they are short-term memory and long-term memory. Short-term memory has a capacity of 7+/-2 items, the duration of any information can last between 0-96 seconds and the encoding is either visual or acoustically, this idea relates back to cognitive processes; maintenance rehearsal, as this use of encoding is shallow processing, for example repetition, using acoustics and use of visuals to be able to recognise and identify a position of a photo. On the other hand long-term memory uses elaborative rehearsal, meaning a deeper process to be able to retrieve/recall memories and information, which is then recalled within our short-term memory. The capacity has the ability to be unlimitless as well as the duration. ...read more.

Middle

the words in the beginning so much that the information would transfer from STM to LTM. This caused participants to pay less attention to the words in the middle. Therefore, words at the end were remembered and made accessible via STM. This strengthens the validity of the multi-store model as this shows that short-term memory and long-term memory are two separate models found within the brain (STM, prefrontal cortex whereas LTM, hippocampus), which supports the prediction made from the multi-store. The process of rehearsal is also supported by the models prediction as words have been transferred from the beginning of the list from short-term memory to long-term memory, thus demonstrating evidence of primary effect. However, one problem with this research is that participants may have misheard the words, yet recalled the original words correctly. ...read more.

Conclusion

we must be able to remember numbers, pictures and letters. This means that we can generalise the results from this experiment, thus it can be taken outside the research environment and applicable in everyday life. A weakness of this model is that there is research that contradicts its predictions in that long-term memory is not one single store but is made of several sub-stores; the sub-stores consist of, procedural, episodic and semantic. This therefore weakens the validity of the model because it does not account for these other sub-stores that hold different units, making the multi-store model too simplistic. This is shown by Spiers experiment, of studying patients with amnesia. Overall there are many positives and negatives towards the idea of the multi-store model, in my opinion; I feel that there is more positive feedback towards this model as it demonstrates studies toward capacity, duration and encoding. And that the model produces testable predictions, which is important for the scientific process, to enable theory testing and verification. ...read more.

    lifetime, although loss is possible from this store through decay or interference. In order to recall information, it must be 'retrieved' from the LTM to the STM. This information needs to be re-lived in the STM before it is released through action/ speech.

  2. SHORT TERM MEMORY

    This informed them of what each of their individual results showed, and what conclusion we have made from their result in relation to the aim of the investigation. And it thanked them all for participating in the investigation. (See appendix 6)

  1. Describe and evaluate the multistore model of memory

    A 'chunk' represented a meaningful collection of items. This research supports the existence of STM as a limited store and turn suggests that memories are held in a fragile state and there must be another store for which our other memories are located.

  2. Memory: Rote Rehearsal and Mental Imagery.

    the sample was limited to a relatively small number of pupils in Small Heath 6th form in Birmingham, England. Implications of the research: I could re-do this experiment but test imagery with other memory aids such as mnemonics and colour coding.

  1. Describe and Evaluate the MultiStore Model of Memory

    Acoustic rehersal is sometimes the best way of putting information into LTM for more permanent retention.

  2. Investigating the short-term memory

    the short term memory and prove that if the information is not rehearsed then it can't be stored in the short-term memory therefore causing the participant to forget the information. METHOD DESIGN An experiment was conducted for this investigation. The type of experiment used was a lab experiment, as it was conducted in controlling and manipulating the independent variable.

  1. Alternatives to the multi store model of memory.

    suggests that there is one store for visual processing and one for processing sound as suggested by the WMM. An evaluation point for WMM can be that brain scans support the WMM, Dolcus et al used fMRI scans to study the effects of dual task performance on brain activity.

  2. Outline and evaluate the multi store model of memory.

    More evidence to support the multi-store model can be seen by the serial position curve experiment, by Glanzer and Cunitz. The experiment produces the primary effect, where many words are recalled from the beginning of the list, and the recency effect, where many words are also recalled from the end of the list, but not so many from the middle.
