Outline and evaluate the multi-store model

Extracts from this document...

Introduction

´╗┐Long term memory Capacity: unlimited Duration: unlimited Encoding: semantic Forgetting interference/decay Short term memory Capacity: limited Duration: very limited Encoding: acoustic Forgetting displacement Sensory memory Capacity: unlimited Duration: very limited Encoding: senses Decay Retrieval Rehearsal Environmental stimuli Maintenance rehearsal Information retrieval Attention The multi-store model was suggested by Atkinson and Shiffrin (1968). They imagined memory as a flow chart. At each stage of the process, there are limitations in terms of Capacity, duration and encoding. Sensory memory: a set of limited capacity and holds information for a very brief period of time. Short-term memory: a temporary store where small amounts of information can be kept for brief periods. The information can be lost easily. Long-term memory: a permanent store where limitless amounts of information can be stored for a long time. Capacity: the amount of information that can be held in the memory at one time. Duration: the length of time that memories can be held Encoding: the way that the information is represented in the memory store e.g. ...read more.

Glanzer and Cunitz also conducted an experiment testing short-term memory. The participants were given a list of words presented one at a time group 1 were asked to recall words immediately after been presented but group 2 were given distracting tasks after the words and counted backwards in threes from 30 seconds they were then asked to recall words . Glanzer and Cunitz found that group 1 was remembered more than group 2. Baddeley carried out an experiment to test both short-term and long-term memory. He used 5 acoustically similar and 5 acoustically dissimilar words and 5 semantically similar and 5 semantically dissimilar words. He modified this to fit the long-term memory by changing 5 words into 10 words and prevented the participants from rehearsing by distracting them after each word. He found and concluded that acoustic similarity had no effect on recall but that words with similar meaning were poorly recalled. He concluded that long-term memory codes were mainly semantically. ...read more.

Conclusion

Clive Wearing: has a viral infection, can recognise his wife but has no recollection of her visit a few seconds after she?s gone, he can still play the piano. This also goes against the multi-store model because if he can enter his long-term memory to recognise his wife and play the piano. But cant remember things that happened seconds ago then his memory doesn?t work in a flow chart manner. The multi-store model in some cases works but others like Clive wearing and KF doesn?t apply. However the multi-store model has a lot of research to support it and build on and most researchers agree that short-term memory and long-term memory. On the other hand is far too simplified and these are artificial studies and not realistic. Not all events need rehearsal for example flashbulb memories go straight to long-term memory. In conclusion the multi-store model is supported by artificial, laboratory studies and might not reflect how memory works in everyday life. As well as this studies have been conducted that go completely against the studies previously conducted. Researchers have now looked to new models to explain memory processes more fully.

    Are memories permanent and unalterable?

    4 star(s)

    Skeptics and many clinicians support the argument that recovered memories are fabrications and they evaluate this opinion with scientific evidence. The phenomenon of infantile amnesia is one of them, and suggests that things learned from specific experiences during infancy are forgotten rapidly and it's unlike to be remembered at all during adulthood.

    The phonological loop is known as the 'inner voice', which holds words and rehearses any words that are currently being considered. It stores a limited number of sounds for brief periods. It is now thought to be made up of two components, as suggested by Gathercole and Baddeley, 1993.

  1. SHORT TERM MEMORY

    This is because all participants were mainly from the same area. Human error may have also caused the research to have some weaknesses as it was hard to for the experimenter to stop the clock precisely after each appropriate time resulting in some participants having more time to rehearse the words.

  2. Investigating the short-term memory

    Deceiving the participants makes them feel devalued. If participants were deceived, and they ended up knowing about it, then they may withdraw their result from the investigation, affecting the overall result, or meaning the experimenter may have to find more participants.

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

    Although areas of Atkinson and Shiffrin's model have been supported by evidence provided both through real life situations and through laboratory experiments, there is also much criticism around the Multi Store Model of memory. It has been argued that the Multi Store Model is too linear; it is believed the

  2. Psychology Retrospective Interference coursework

    Deceiving the participants and not receiving their informed consent were considered as limitations. First, the participants were not fully 'informed' of all aspects of the research. However, a major problem with informed consent is the possibilities that the researcher will reveal their aim which would generate invalidate findings.

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

    The investigation began by participants being shown random sequences of 6 letters. These letters were shown in rapid succession on a screen and participants were required to write them down. As the rate of presentation was too fast, they had to rely on their memory.

  2. Describe and evaluate models of memory.

    Bower and Springton (1970) also researched the capacity of short-term memory by presenting participants with one or two letter sequences. the first sentence contained well known groups of letters:mfi,plc,aeb,but the second contained the same letters but in a different order:imf,icp,eba.the results showed that the first sentence was definitely the best
