- 1Supporting experimental evidence for the duration of STMPeterson & Peterson (1959) found that when using a distractor task to prevent the rehearsal of single 'trigrams' decay occurs in the short-term store after a period of 15 seconds
- 2Supporting experimental evidence for the duration of LTMBahrick et al. (1975) found that identification of names and faces from high school yearbooks was very accurate after many years of leaving school, showing that although memory deteriorates over time, long-term memory for faces and names is stable over the passage of time
- 3Supporting experimental evidence of separate STM and LTM storesGlanzer & Cunitz (1966) researched serial position effect and found that the last words encoded in a list are some of the most recalled due to remaining in the STM (recency effect), as well as finding that the first words encoded in a list were the most recalled due to the rehearsal of early information which is then stored in the LTM (primacy effect)
- 4Supporting clinical evidenceCase studies of brain-damaged patients such as Henry Molaison (HM) provide supporting evidence; HM was unable to transfer information from his short-term to long-term store, demonstrating the separation between short-term and long-term memory as proposed by the MSM
- 5Opposing experimental evidenceCase studies of brain-damaged patients such as Kent Cochrane (KC); he could recall facts from his LTM but could not remember personal events in his life before the accident, suggesting that LTM is not one single store but that we have different LTM stores, e.g. LT procedural memory of practical skills and LTM stores for factual information and personal events (CP There are ethical concerns about invasion of privacy in cases such as KC as he was arguably over studied and experimented on)
- 6Reductionist/SimplifiedWeakness: Describing memory as an input-process-output system is over simplistic and ignores individual differences in memory, as well as underplaying the interconnections between the different memory systems by proposing that the memory has distinctly different stores
CP: However by being reductionist and artificially breaking up the memory stores the MSM makes it easier to study memory experimentally - 7Scientific credibilityStrength: The model is grounded in research that is experimental and therefore well controlled, replicable, and with proven reliable results
- 8Weakness: The MSM does not adequately explain how:STM is adversely affected when carrying out similar dual tasks since the theory suggests that STM capacity is unaffected by type of task, while the WMM can explain dual task performance and is seen as a more dynamic model of STM
- 9Contributions/applications to societyStrength: Students can understand that to learn effectively and do well in exams they need to rehearse material before an exam which may include chunking strategies and using mnemonics
