The multi-store model of memory

The multi-store model of memory

1. duration

   • less than 30 sec
   • Peterson and Peterson: Trigrams

2. Encoding

   • Mostly acoustic
   • Baddeley: acoustically similar words

3. capacity

   • 7 +/- 2
   • Jacobs: lists of letters: 7 Lists of numbers: 9

4. STM

5. LTM

   • capacity
     • Unlimited
     • Linton: wrote a diary and remembered dates
   • Encoding
     • Semantic
     • Baddely: acoustically or semantically similar words: semantic confusion
   • duration
     • A life time
     • Barick et al: Identifying old school friends

6. Evaluation

   • Lead to the WMM
   • Lots of support for different memories stores of memory
     • K.F : STM was damaged in an accident, capacity of 1 or 2 digits, but his LTM was fine
     • H.M : couldn't encode new LT memories but STM was fine
   • Too focus on structure and not enough on processes
   • Cohen : memory capacity should be measured by the nature of the things remembered
