The multi store model of memory
Cards in this deck (6)
- 1Separate memory stores including sensory register, STM and LTMSR: Has 5 stores, 1 for each sense. Duration: Less than half a second. Capacity: high. Coding: depends on the sense e.g. visual.
- 2To transfer info from the SR to the STM attention needs to be paid to it.STM: Duration: 18 to 30 secs unless information is rehearsed. Capacity: between 5 and 9 items. Coding: Acoustic
- 3Transer from the STM to LTM: maintance rehearsal occurs when we repeated information to ourselves. we can keep the information in the STM as long as we rehearse it but if we rehearse it for long enough it transfers to the LTM.LTM: A permanent memory store. when we went to recall material it has to be transferred to the STM by retrieval. Duration: potentially a life time. Capacity: potentially unlimited. Coding: Semantic (terms of meaning)
- 4The MSM is supported by research showing the STM and LTM are different, Baddeley (1966) found we tend to mix up words what sound similar when using the STM. But we mix up words that have similar meanings for LTM. Showing clearly there is different coding methods for both stores, this supports the MSM view of 2 different memory stores.However, evidence suggests there is more than 1 STM store. Shallice and Warrington (1970) studied KF a patient with amnesia. His STM for digits was poor when they read them out loud to him. when he read the digits the recall was better. MSM states there is only one STM but KF suggests there must be a short term memory store to process visual information and another to process auditory information. A better explanation for this finding would be the WMM as it includes the separate stores.
- 5MSM only explains one type of rehearsal, Craik and Watkins (1973) argued that there is 2 types of rehearsal - maintance and eleborative. Eleborative rehearsal occurs when you link or process information to your existing knowledge. Therefore showing the the MSM lacks research findings.Research studies that support the MSM use arfticial materials, researchers often asked participants to recall digits, letters or words. Peterson and Peterson (1959) used consonant syllables. In everyday life we form memories related to all sorts of useful things e.g. faces. This suggest that the MSM lacks external validity. As the research findings reflect how memory works with meaningless information in lab testing but does not reflect everyday life.
- 6The MSM oversimplifies the LTM, there is alot of evidence that LTM is not a unitary store. As we have one LTM for memories of facts (semantic) and another for memories on how to ride a bike (episodic). Showing that the MSM is limited as it does not reflect these different types in the LTM.xxx
