MSM Strengths: Primacy/Recency Primacy/Recency is an experiment where participants are given a list of 20 words in succession and the experiment is interested in where the most words are remembered. Primacy/recency proves MSM because the beginning of the list is first transferred to the LTM, the middle is forgotten due to the fact that it is being transferred from the STM to the LTM and the end of the list is stored in the STM so you are only able to write some of the words down. The whole of the experiment proves that there is a long term and a short term memory which MSM states exist. Clive Wearing is a man that suffers from the world’s worst case of amnesia. His memory is 30 seconds long and he doesn’t have the capacity to make new memories. Clive proves that MSM is true because the part of his brain that was damaged has stopped memories from being transferred from the STM to the LTM. Weaknesses: KF, who suffered a motorcycle accident causing damage to his left parietal occipital region of the brain had a number of interesting deficits that have been intensively studied (e.g. Shallice & Warrington, 1970). KF showed very poor digit span (usually less than 2 items), but good performance on tasks that seemed to indicate an intact long-term store. For example, he was still able to store new information. In fact he could learn a 10 word sequence in fewer trials than normal controls and still retained seven of the 10 items some months later. The multi-store model predicts that this should not be possible since an intact STM is required to transfer information to LTM. We have enormous amounts of information in LTM even though we have probably not rehearsed much of it. Despite the important role that rehearsal is supposed to play in the multi-store model, studies actually show a low correlation between the amount of rehearsal and how much information is
