MSM STRENGTH- Peterson and Peterson (1959)
Found that when asked to recall a meaningless trigram (BHK), interference tasks such as counting backwards in threes cause participants to forget it after 9 seconds or a maximum of 18 seconds.

MSM STRENGTH- Glanzer and Cunitz (1966)
Presented participants w/ world list and found that ppl remembered more from the beginning (primacy) and the end (recency) of a list than from the middle. Supports STM and LTM through primacy and recency respectively.

MSM STRENGTH- Clive Wearing
Received brain damage to his hippocampus after viral infection. He could use his STM to remember things for about 20 seconds but he was unable to encode this into his LTM, thus making him forget nearly everything except his wife and piano playing.
3 of 8
MSM STRENGTH- HM
Had brain surgery to cure epilepsy and had his hippocampus damaged, unable to make new memories. Still had many memories from before the surgery and could remember those, suggesting he had LTM but couldn't add to it.
4 of 8
MSM WEAKNESS- Seitz and Schumann-Hengsteber
Found visual-spatial tasks wouldn't interfere with someone's ability to do sums- suggests separate short-term memory stores.
5 of 8
MSM WEAKNESS- Shallice and Warrington (1970)
Report of K.F. who could still add memories to his LTM despite his STM being so damaged he couldn't report back more than 2 digits. Cannot be explained by MSM but can by WMM.

MSM WEAKNESSES of WMM
The MSM has often been criticised as being too simplistic, which arguing that there's only one store in STM. However, WMM is a better explanation that is more in-depth.
7 of 8
MSM WEAKNESS of experiments (like Peterson and Peterson [1959])
Often based on meaningless trigrams that are very artificial and not representative of real life. In real life there are often consequences to forgetting certain information. Thus, the MSM doesn't explain how memory works in real life settings.
