Describe and Evaluate the Multi-store model of Memory.

Extracts from this document...

Introduction

´╗┐Chloe-Louise Applewhite Describe and evaluate the multi-store model of memory? Atkinson and Shiffrins multi-store model consists of three hypothetical stores; the sensory Store, the short term memory and the long term memory. They suggested that that, the Multi-store model (MSM) was linear, there for all information must go through all the stores. They also suggested information enters the system from the environment, through the several stores which are our five senses. They constantly receive information; most of this information doesn?t have much attention paid to it. There for if you focus attention on to the sensory stores; it is then transferred to the Short-term memory (STM) acoustically. Then the Information is then rehearsed; this then helps the information to be transferred from STM to the Long-term memory (LTM) ...read more.

The results showed that condition 1 participants showed primacy effect, which is the words they heard first, and the recency effect which is where they only recalled the last few words in the list. Participants in condition 2 only showed only the primacy effect as they only remembered words from the start of the list. This study supports the MSM by providing evidence that memory is in three distinct stores. The primacy effect, is where information processed earlier is constantly being rehearsed, which results in the information being encoded in to the LTM. The recency effect is where the last bit of information processed into your memory due to the 18-30 second duration rate, thus easily recalled. In the LTM, the capacity is unlimited due to the infinite rate of duration, the information may last all of your life here. ...read more.

Conclusion

However the study was very high in ecological validity as it was a real life situation. Despite giving evidence that there are separate stores of memory, the H.M study cannot be used to explain why his LTM was intact, whereas H.M?s STM was damaged as the MSM suggests that all information must pass through the STM to reach the LTM, hence the referral to it being a linear model. The MSM is also criticised for being oversimplified compared to other models, such as the working memory model, which study suggest STM is three different stores. It?s oversimplified because, it focusses mainly on structure, and too little on the processes of memory. It also uses a lot of lap experiments, there for you are more likely to have demand characteristics. Lastly the LTM may help us interpret information in our STM, but in the MSM, there is no such suggestion or enough emphasis on the short term, or long term components. ...read more.

    Chunking can increase the capacity of short-term memory. For example, the letters "b d e" constitute three units of information while the word "bed" represents one unit even though it is composed of the same number of letters. Chunking is a major technique for getting and keeping information in short-term memory; it is also a type of elaboration that will help get information into long-term memory.

    KF, a motorcycle accident victim investigated by Shallice and Warrington, 1970, suffered from the reverse of this memory impairment. He had no difficulty in transferring new items into LTM but had a grossly impaired digit span. He has good long-term recall but can only hold two items at any one time in his short-term memory.

    The mean was calculated by adding up all the values, and dividing it by how many of the value there is. The median again shows that group 1 performed better having a median of 8.5 whereas group 2 has a median of 6.5.

  2. Investigate into the Primacy and Recency effect

    Upon looking at graph 1, it is clear that a primacy and recency effect does not exist in each condition. As said in the introduction a primacy and recency effect exist if a graph of the results forms the shape of a U.

    This variable therefore was controlled by not letting any student having the knowledge or studying psychology took part in the experiment. This was ensured by asking them before the experiment. Any students that had knowledge of psychology were eliminated from the experiment.

  2. Investigating the short-term memory

    The results clearly showed that group 1 without the music distraction recalled the words form the list better than group 2 with the music distraction. Conducting this experiment showed that the music as an added distraction affected the rehearsal process for the words.

    Without rehearsal, there is no semantic relevance to the associated piece of information rehearsal is a procedure by which the individual can apply meaning or association to this information, if this does not occur then it is not transferred to the LTM and subsequently forgotten.

  2. 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.
