  • Multi-Store Model
    • Characteristics
      • STM
        • Duration-18-21 seconds
        • Capacity- 7+/-2 items or chunks
        • Encoding- acoustic
        • Retrieval- rapid, sequential scan
          • Rehearsal increases strength of memory trace
      • LTM
        • Capacity- limitless
        • Duration- at least 48 years-lifetime
        • Encoding- semantic
      • Sensory
        • Small Duration
        • Small Capacity
    • Evidence
      • Sensory
        • Sperling
          • Lab
          • Letters- 1/20th of a second on a screen
            • Recalled 4 letters better than 12
          • Strength
            • Cause and effect can be established
          • Weakness
            • Highly artificial
      • STM
        • Peterson and Peterson
          • Duration
          • Lab
          • Non-sense Trigrams
          • Highly artificial
          • Cause and effect
        • Miller
          • Word string
          • Lab
          • Cause and effect
          • Highly artificial
      • LTM
        • Brady
          • Encoding
          • Gave people 5hrs to learn 2500 words
            • Most people could remember most items
          • Lab
        • Bahric
          • Field
          • 48 years later
            • Remembering yearbook photos
        • Encoding
          • Washington state memory experiment
        • Retrieval
          • Tip of the Tongue
            • Only recovers partial fragments
    • General
      • Structures
        • STM
        • Sensory
        • LTM
      • Processes
        • Attention
          • Sensory
          • STM
        • Maintenance rehearsal
          • Elaborative rehearsal
            • LTM
      • Evaluation
        • Model is too simplistic
        • Brain Damage
          • HM
            • Evidence for STM and LTM stores being in different areas of the brain
            • Brain surgery
            • Severe Amnesia
              • Major problem in LTM
            • Have no idea what he was like before hand.
            • Unique
              • Can't generalise
