  • Multi Store Model
    • Sensory Memory // SM
      • Capacity: Quite Large
        • Every input comes through and is processed or lost
      • Duration: Very Brief (0.5 seconds)
      • Encoding: Modality Specific
        • Info comes in from a sensory organ and is stored as that sense
      • Sperling Study
        • 12 letters shown on a screen for a very short yet accurate period of time
          • Participants asked to recall as many as possible
            • Average recall of 4.5 of 12 letters
      • Averbach Study
        • Two rows of 8 letters shown on a screen for 0.5 seconds
          • One letter had a dot above it
            • Recall of letter with dot was 75%
    • Short Term Memory // STM
      • Capacity: 7 ± 2 pieces of info
        • 'Magic Number 7'
          • Size of the information doesn't matter
          • Chunking can increase the capacity
      • Duration: Up to 30 seconds
        • Rehearsed info can be maintained in the STM
        • Peterson and Peterson Study
          • STM Duration test
          • Participants shown a consonant trigram (eg. NVB)
            • Participants asked to recall after 3,6,9,12,15,18 seconds
              • Interference task carried about to prevent rehearsal
                • 80% recall after 3 seconds.
                • 10% recall after 18 seconds
      • Encoding: Mainly acoustic
        • Baddeley Study
          • Encoding: Mainly semantically
            • Info has a particular meaning or can be applied to a context
          • Using either STM or LTM, participants asked to recall words from 4 conditions
            • 1. Acoustically similar
            • 2. Acoustically dissimilar
            • 3. Semantically similar
            • 4. Semantically dissimilar
            • STM recall showed acoustically similar words were mistaken
            • LTM recall showed semantically similar words were mistaken
    • Long Term Memory // LTM
      • Duration: Potentially lifelong
      • Encoding: Mainly semantically
        • Info has a particular meaning or can be applied to a context
    • Milner Study
      • STM and LTM Distinction
      • Case study of Young man 'HM'
        • Underwent brain surgery and gained memory impairments
        • Used clinical interviews and memory tests
          • Could recall events from before surgery
          • STM was found normal
          • Unable to retain new information in LTM
