    • Supporting research: The case of HM
      He had severe epilepsy and had surgery to remove his hippocampus from both sides if the brain (central feature of memory function). He completed tests when he woke up from surgery
    • Findings from the case of Hm
      When his memory was assessed in 1957, he though it was 1953 and that he was 27, however, he was 31. He didn't remember about the operation and didn't remember speaking with someone an hour earlier. His LTM was tested over and over, but he didn't improve with practice. He would read the same magazine repeatedly without remembeing it. He couldn't recall what he ahs eaten earlier the same day. He still performed well on immediate memory test which measured STM.
    • Counterpoint
      • despite this support in everyday life form memories for usual things- names, faces and places
      • many of the studies that support Msm don't use this material, they use artificial stimuli such as digits and words.
    • Limitation- evidence for more than one STM store. the MSM states there is only one STM store, however, evidence from people suffering from amnesia suggests there is more than one store.
    • Shallice and Warrington (1970) studied a patient KF amnesia after suffering from a motorcycling accident. They found when asked to recall from STM it was poor when the numbers were read out loud to him When he read all the numbers him self, his recall was much better. this suggests there is a short-term memory store to process auditory information and one to process visual information.
    • limitation: more than one type of rehearsal the MSM states you need prolonged rehearsal for memories to transfer to the LTM, this means the more you rehearse the more likely it will transfer (amount ) you do.
    • Limitation: more than one type of rehearsal
      Craik and Watkins (1973) say its not about the amount its about the type of rehearsal. Elaborative rehearsal: needed for LTM linking info to your existing knowledge or think about what it means. MSM does not fully explain how LTM Storage us achieved.
