Outline and Evaluate the Multi Store Model of Memory

The multi store model of memory is split into three different stores. The sensor memory, short term memory (STM) and long term memory (LTM). All three memory stores can contain a different capacity of memories, get encoded in a different way and the duration of the memory is also different. Our memories first get processed by paying attention to our surroundings, environment and to pieces of information we want to remember. This information enters the sensor memory. This piece of information then gets encoded by one of our five senses (smell, touch, taste, hear and feel) depending on the type of information. If enough attention gets paid to the information piece then it will enter the short term memory which has a capacity of “the magic number 7, plus or minus 2” which has a duration of 15 to 30 seconds before the memory decays. The short term memory codes for all information acoustically (according to the sound). If the information in the STM store happens to be visual then it gets encoded/transformed into acoustic codes. After all the information pieces have been coded for elaborative rehearsal takes place which will transfer the memory in to the long term memory store which has a unlimited capacity and can last for a lifetime. If someone experiences an emotional or meaningful event the memory can go straight to the LTM store without elaborative rehearsal taking place. Also, the information in this store can be used in STM when needed if someone wants to remember something, but it can also be forgotten through decay or displacement. One strength for this model is that it is based on real people and their experiences with memory, rather than carrying out an experiment in the laboratory and using the results from that. This then makes the model a lot more valid and means that it can be used in everyday life. For example, Clive Wearing who has lost the
