Memory- multi-store model

Stimulus
1. Sensory stores
  1. Iconic
  2. Echoic
  3. STM
    1. Response (remembering)
    2. Prolonged rehearsal
      1. LTM
        Retrieval
    3. Maintenance rehearsal (rehearsal loop)
Sensory register
1. Five stores, one for each sense
2. Echoic- auditory coding
3. Iconic- visual coding
4. Duration- 0.5 seconds
5. Very high capacity
STM
1. Small capacity- 5-9 items
2. Short duration- 30 seconds
3. Coded acoustically
4. Maintenance rehearsal
  1. Repetition of material
    1. Remains in STM
LTM
1. Unlimited capacity
2. Permanent
3. Coded semantically
4. Retrieval
  1. Necessary to recall information in LTM
5. Prolonged rehearsal in STM
Created by Atkinson and Shiffrin, 1968
1. How information flows through the memory system
Evaluation
1. Supporting research
  1. LTM and STM are qualitatively different
    1. Baddeley's study on coding
    2. MSM states there are 2 separate stores
2. There may be more than one type of STM
  1. May be different stores for visual and auditory information
    1. Unitary store is a limitation
    2. Studies into amnesia showed digits read out loud more difficult to remember than when written down to read
3. More than one type of rehearsal
  1. Elaborative rehearsal
    1. Linking information to current knowledge
4. Issues with research support
  1. Artificial stimuli
    1. Difficult to generalise to typical life
5. More than one type of LTM
  1. Episodic, Semantic, Procedural
    1. Tulving
