The multi-store model of memory has been criticised for placing too much emphasis on the role of rehearsal. Whilst rehearsal is important in moving information from short-term memory to long-term memory, it is not the only way information moves between the stores. For example, if a piece of information is given meaning (via semantic elaboration), it can be transferred to long-term memory without repetition. This means that the model is not detailed enough in its explanation of how things are transferred to long-term memory. In addition, the model oversimplifies short-term memory. Several findings that contribute to the working memory model (Baddeley and Hitch, 1974) have shown that short-term memory is not unitary but made up of lots of different stores for different types of information. This means that the multi-store model of memory cannot fully explain how we process information, as it suggest that short-term memory is one complete store.
