Strengths and Weaknesses: Multi Store Model MemoryWatch
Please help, thanks
Strengths and Weaknesses of the Multi Store Model of Memory?
Please help, thanks
S: seperate stores are good as research shows that one store can be damaged without affecting the other
-role of importance shows why people remember some things more than others
-role of rehearsal is representative of everyday life
-it is supported by the primacy and recency effect ( you can remember the start of a piece of info as its in your long term store, you can remember the end as its still in your short term store )
W: Oversimplified as research suggests that there is more than one type of short term store and more than one type of long term store), too generic
doesn't explain flashbulb memories
Research behind it comes mainly from lab experiments which are not ecologically valid and the multi store model may not explain how we form memories in everyday life with more meaningful memories.
Can't remember anymore at the moment, sorry!
Many memory studies provide*evidence*to support the distinction between STM and LTM (in terms of encoding, duration and capacity). *The model can account for*primacy & recency effects.
The model is*influential*as it has generated a lot of research into memory.
The model is supported by studies of amnesiacs: For example the*HM case study.* HM is still alive but has marked problems in long-term memory after brain surgery. He has remembered little of personal (death of mother and father) or public events (*Watergate*,*Vietnam*War) that have occurred over the last 45 years. However his short-term memory remains intact.
The model is*oversimplified, in particular when it suggests that both short-term and long-term memory each operate in a single, uniform fashion.* We now know is this not the case.
It has now become apparent that both short-term and long-term memory are more complicated that previously thought.* For example, the*Working Model of Memory*proposed by Baddeley and Hitch (1974) showed that short term memory is more than just one simple unitary store and comprises different components (e.g. central executive, visuo-spatial etc.).
In the case of long-term memory, it is unlikely that different kinds of knowledge, such as remembering how to play a computer game, the rules of subtraction and remembering what we did yesterday are all stored within a single, long-term memory store.* Indeed*different types of long-term memory have been identified, namely episodic (memories of events), procedural (knowledge of how to do things) and semantic (general knowledge).
The model suggests*rehearsal*helps to transfer information into LTM but this is*not essential.*Why are we able to recall information which we did not rehearse (e.g. swimming) yet unable to recall information which we have rehearsed (e.g. reading your notes while revising). Therefore, the role of rehearsal as a means of transferring from STM to LTM is much less important than Atkinson and Shiffrin (1968) claimed in their model.
However, the models main emphasis was on structure and tends to*neglect the process elements of memory*(e.g. it only focuses on attention and rehearsal).
The*multi store model*has been criticized for being*a passive/one way/linear model.
