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.

    However, if I ask, "What is your telephone number?" your brain immediately calls that from long-term memory and replaces what was previously there. Decay is similar as the information disapperas as time passes by as the duration of STM is limited. Chunking can increase the capacity of short-term memory.

    Milner, 1966, reported on a young man, referred to as HM, who was left with severe memory impairment after brain surgery. He was able to talk normally and to recall accurately events of people from his life before surgery, and his immediate digit span was within normal limits.

    For the echoic store, the fact that we put together and understand sentences easily, rather than finding meaning in each individual word. For these type of studies, problems arise because everybodies minds are different with different memory capabilities, personalities etc so results are nearly impossible to generalise to all people.

  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. Investigating the short-term memory

    The experimenter for each group would read them out. This list included words that sounded the same and has similar meanings. The 10 words were; log, fast, dog, sign, lip, teeth, last, hip, line, sweet. (See appendix 4). 20 consent forms were needed as participants had to give their consent before participating.

  2. Explain and evaluate the three models of memory.

    For instance if you say a phrase out a loud but at the same time listen to music, your STM or central executive will process one while the other is stored, but once both are processed there may be some confusion between the two as they are both acoustically sounding and have both occupied the phonological loop.

  1. Investigation into acoustic and visual encoding in short-term memory

    As the investigation is an experiment the experimental design the researcher will be making use of is repeated measures. This design involves exposing every participant to each of the experimental conditions so in effect participants are used as their own controls.

  2. Describe and evaluate the multistore model of memory

    Evidence to show the existence and capacity of the STM has long been researched. Although the model was developed much later, Jacobs (1887) used the digit span technique to test the capacity of memory and in the context of this model, the short term memory.
