Multi-Store Model Studies
- Sperling 1960 Sensory register support
  - What done?
    - Briefly displayed grids of 3 rows of letters
  - What found?
    - Could only recall 4-5 but were aware there were more letters
  - So what?
    - Supports sensory register aspect of MSM
- Baddeley 1966 Coding Suupport
  - What found?
    - Acoustically similar words were confused after little delay before recall
    - Semantically similar words were confused after 20 minutes delay before recall
  - So what?
    - STM is encoded acoustically
    - LTM is encoded semantically
- Miller 1956 Capacity of STM
  - What found?
    - 7 2 +/- chunks of information can be recalled
  - So what?
    - Chunking increases capacity
- Glanzer et al
  - What done?
    - Demonstrated LTM and STM are different stores through primacy and recency effect
      - Primacy
        Remembering the first word
        Indicates transfer to LTM
      - Recency
        Remembering the last word
        Indicates transfer to STM
- Peterson and Peterson 1959 Duration of STM
  - What found?
    - 90% remembered after 3 seconds
    - 2% remembered after 18 seconds
  - So what?
    - STM lasts approximal 20 seconds when rehearsal is prevented
- Bahrick et al 1975 Duration of LTM
  - What done?
    - Participants asked to recall school classmates
      - Once without photos
      - Once with photos (photo recognition)
      - Once when given a name and asked to match photos (Name-recognition task)
  - What found?
    - 15 years after leaving school
      - 90% name and face accurate
      - 60% accurate on free recall
    - 48 years after leaving school
      - 80% name and face accurate
      - 30% accurate on free recall
  - So what?
    - Better recognition than recall
      - Cues prompt out LTM
