Outline and Evaluate the MSM
The Multiple Store Model has three distinct stores; Sensory Memory-SM; this is things that are going on around you that you sense, Short Term Memory- STM; this is a store for items that you remember for a short period of time and finally Long Term Memory- LTM; this stores items for a long period of time.
Sensory Memory has a vast capacity of things that it can store; these can be things like noises outside, your temperature or hunger. The duration for this store is 50 milliseconds, this means that each item will only be stored for a very short period of time, but many can be stored. The way in which memory is stored in the SM is by touch, taste, visual, ecoustic etc. They way in which the memory transfers from SM STM are by attention being given to the item. For example you will only realise that there are birds flying outside your window if your attention is being given to the things outside. This allows you to process and store the memory for longer. This leads on to Short Term Memory, which has a duration of 18 seconds in the STM. Encoding for STM is ecoustic and visual, which means it is stored by sound and images in the brain. Its capacity is 7±2 items, so either between 5-9 items. The transfer of STM LTM is via rehearsal. This allows Short Term Memory items to be held for much longer period of time. LTM has an unlimited capacity and an unlimited duration. LTM is stored by semantic encoding.
