The Multi-Store Model was the first complex model of human memory. It was proposed by Atkinson and Shiffrin whom divided memory into separate, unitary (a number of areas or groups that are joined together) stores.
What is the Sensory Register?
The Sensory Register is a store of memory which is coded through senses. It has a very high capacity but a very small duration (less than 1/2 a second). If attention is paid, then the information moves to the short-term memory.
Short-term memory
Short-term memory has a capacity of 7 +/- 2 chunks and a duration that is limited (18-30 seconds). It's coding is primarily acoustic. If we repeat information, -also known as maintenance rehearsal- we can keep it in the short-term memory.
Long-term memory
Long-term memory's capacity and duration is potentially unlimited, and its coding is primarily semantic. If rehearsal of information is prolonged, it will pass from STM to LTM.
Information can be forgotten...
Information can be forgotten because of decay in any store, also by displacement in STM and interference in LTM
