More than one STM store

• P- one limitation of the MSM is evidence of more than one STM store
• E- Tim Shallice and Elizebeth Warrington (1970) studied a client they referred to as KF who had a clinical memory disorder called amnesia. KF’s STM for digits was very poor when they were read out loud to him. but his recall was much better when he read the digits to himself
• E- further studies of KF and others showed that there could be another short-term memory store for non- verbal sounds
• L- this evidence suggests that the MSM is wrong in claiming that there is just one STM store processing different types of information
