Describe and evaluate the multistore model of memory. Refer to evidence in your answer. [16 marks]

A01

• diagrammatic representation of memory

• linear flow of information between stores

• Sensory register - include encoding, capacity and duration

• STM - include encoding, capacity and duration

• LTM - include encoding, capacity and duration

• how info moves: attention, maintenance rehearsal, retrieval, displacement, decay etc.

A03

• research support

  • Baddeley (1966) list recall, encoding of STM+LTM

  • Jacobs (1887) digit span, capacity of STM

  • Miller (1956) 7+-2, chunking, capacity of STM

  • Peterson and Peterson (1959) nonsense trigrams, duration of STM

  • Bahrick (1975) yearbook, duration of LTM

    • research support is based on artificial studies

• STM is not a unitary store - KF case study (Shallice and Warrington)

• LTM is not a unitary store - Clive Wearing

  • supported by Tulving’s PET scans of episodic vs semantic memory

• WMM may be a superior model

• another type of rehearsal needed for transfer to LTM - elaborative
