, MULTI-STORE MODEL OF MEMORY
Features of memory stores
Coding = how info is represented in memory using a particular format or code.

Capacity = amount of storage spaces in memory.

Duration = how long info lasts before it is forgotten.



Multi-store model of memory




• Structured as 3 separate and different stores
• Stores = unitary and not subdivided
• Info is transferred to LTM via repeated rehearsal of info in STM
• Info is forgotten via decay/displacement/trace decay
