  • Models of memory
    • Multi-store model
      • Developed by Atkinson and Shiffrin
      • Sensory register
        • Coding
          • Modal specific
        • Capacity
          • Very large
        • Duration
          • Less than half a second
        • Transferred to the STM if attention is paid to the stimuli
      • Short term memory
        • Coding
          • Acoustic
        • Capacity
          • 7 +- 2 items
        • Duration
          • 18 seconds
        • Kept in the STM through maintenance rehearsal
        • Transferred to the LTM through prolonged rehearsal
      • Long term memory
        • Coding
          • Semantic
        • Capacity
          • Potentially unlimited
        • Duration
          • Potentially unlimited
        • Transferred back to the STM through retrieval
      • Evaluation
        • Strengths
          • Supporting research
            • Baddeley
              • Shows that STM and LTM are separate and independent memory stores
            • Patient HM
        • Weaknesses
          • May be more than one STM store
            • Shallice and Warrington
              • Patient KF
          • Elaborative rehearsal instead of prolonged rehearsal
            • Craik and Watkins
    • Working memory model
      • Developed by Baddeley and Hitch
      • Central executive
        • Focuses and divides our attention
        • Monitors incoming data
        • Allocates subsystems to tasks
        • Very limited processing capacity
        • Does not store information
      • Phonological loop
        • Phonological store
          • Stores the words you hear
        • Articulatory process
          • Allows maintenance rehearsal
          • Two seconds of speech capacity
      • Visuo-spatial sketchpad
        • Visual cache
          • Stores visual data
        • Inner scribe
          • Records the arrangement of objects in the visual field
      • Episodic buffer
        • Added to the model later
        • Temporary store for information
        • Integrates the visual, spatial and verbal information processed by other stores
        • Maintains a sense of time sequencing
        • Limited capacity of about 4 chunks
      • Evaluation
        • Strengths
          • Supporting evidence
            • Shallice and Warrington
              • Patient KF
            • Baddeley
              • Dual-task performance
        • Weaknesses
          • Lack of clarity over central executive
