Introduction

Jessica May Psychology To what extent does research evidence (theory and/or studies) support the view that short term memory and long term memory are separate stores? Research evidence, theory's and studies supports the views that suggest long term memory and short term memory are separate stores. Short term memory is a system for storing information for brief periods of time. Some researchers (e.g. Atkinson and Shiffrin 1968) see short term memory simply as a temporary storage depot for incoming information, whereas others (e.g. Baddeley 1986, 1990) prefer to use the term 'working memory' to indicate its dynamic, flexible aspects. Long term memory, on the other hand, holds a vast quantity of information which can be stored for long periods of time. ...read more.

they did less well with acoustically similar words than with acoustically dissimilar words. When they recalled the words after an interval (LTM), they performed the same on the acoustic lists but there were differences on the semantic lists. The conclusions made supported the earlier research; this study suggested that short term memory is based largely on an acoustic code, whereas long term memory tends to be based on semantic codes. Other studies into duration in short term memory and long term memory also support the views that short term memory and long term memory are separate stores. In 1959 Peterson and Peterson studied duration in short term memory, they investigated how long information is retained in short term memory when verbal rehearsal is prevented. ...read more.

Conclusion

The 400 participants involved were shown photographs of various people, including those from their high school year books, to test face recognition. They were asked to free recall names of those they attended high school with. The younger participants (who had left high school only 15 years before) were 90% accurate in face recall. This dropped to 70% when the participants who had left high school 48 years before. This study also supports the views that long term memory and short term memory are separate stores. The studies above all support that the two memory stores are separate. If information is given to recall, without interference tasks this information is remembered. Studies show that if sufficient verbal rehearsal takes place then eventually the information will be transferred into the long term memory store. ...read more.

  1. SHORT TERM MEMORY

    This will investigate the process of displacement, which is retrieval failure in the short-term memory. Atkinson & Shiffrin (1968) proposed the idea of a multi-store model. This compares the mental procedures of humans to that of computer operations. In their research, they suggested that there was a series of information processing stages one after another.

  2. 'Organisation in Memory'.

    Noise was a problem in my experiment as too much noise could have affected recall. I attempted to overcome this by conducting my experiment in a classroom where very little background noise was occurring. This is because in general people who entered the classroom were very considerate and understood that experiments were occurring so were quiet.

  1. Investigating the short-term memory

    group 2's recall result, as they were generally lower than those recall result for group 1. This means that the distraction affected the participants in group 2 from rehearsing and therefore making the recall result low. All the results collected using the mean, mode, median, and standard deviation supports the idea that the music was definitely an added distraction.

  2. The Effects of Chunking and Distraction on Short Term Memory Recall

    Following recall the next set of items was presented immediately afterwards. The distraction technique will take the form of a verbal distracter which was the reading out of ten random numbers (between one-nine) the experimenter following the presentation of the lists, prior to recall.

  1. Describe two differences between Short term memory (STM) and Long term memory (LTM) in ...

    The study that provides support for STM and LTM between stores is Atkinson and Shiffrin's Multi-Store Model of memory (1968). This is a two-process model of memory that shows how information flows through the two stores of memory so STM and LTM.

  2. effects of chunking and unchunking on short term memory

    when information was 'chunked' rather than the number of items, when the amount of information averages seven chunks. This is why a familiar date such as 1066 is likely to be a chunk rather than a less meaningful date as 1325.

  1. Report on Psychological Research into Eyewitness Testimony

    designed a technique to maximise the amount of correct information obtained during a police interview. This method was to challenge the standard interviewing process found throughout police units, and the idea that approaches such as hypnosis should be relied on instead.

  2. The Effect of Semantic Organisation of Information on Recall in the Short Term Memory

    Human memory is highly organised. The more organised information is the more likely we are to remember it. In a way, similar to Tulving and Pearlstone's experiment, when subjects are given categorized word lists in a random order and tested in free recall, the almost invariable result is that words are recalled category by category.
