Multi-store model of memory

Multi-store model of memory

1. Basics

   • Developed by Atkinson & Shiffrin 1968
   • Memory divided into 3 linear stores
     • Sensory
     • Short-term
     • Long-term

2. Sensory

   • First store
   • Relatively unprocessed information stored with sensory capacity
     • Duration = fractions of a second
   • Recoding

3. Short-term

   • Second store
   • Mostly acoustically-encoded information stored briefly
     • Limited capacity
       • Aided by methods like chunking
       • Miller
     • Duration = several seconds
     • Rehearsal/retrieval
     • Conrad
   • Requires rehearsal
     • Peterson & Peterson

4. Long-term

   • Third store
   • Mostly semantically-encoded information stored indefinitely
     • Duration = lifetime
       • Bahrick
     • Capacity = unlimited & highly organised
     • Baddeley
