Atkinson + Shiffrin model of memory
1. Divided memory into separate, Unitary Stores
2. Information transfers in a linear fashion
3. Info from the environment passes to the sensory register
5. Very high capacity but very small duration (less than 1½ second)
6. If attention is paid, then the information moves to the short-term memory
7. If we repeat (maintenance rehearsal) the info we can keep it in STM
8. Otherwise the duration is limited (18-30 sec)
9. Capacity is 7±2 chunks and coding is primarily acoustic
10. If rehearsal is prolonged, info will pass to the LTM
11. LTM capacity and duration are potentially unlimited
12. Most LTM is coded semantically (through meaning)
13. Information can be forgotten because of decay in any store, also by displacement in STM, and interference in LTM
