evaluate the MSM

• introduction

  • Atkinson & Shiffrin
  • memory consists of sensory register, short-term and long-term memory
  • information passes through in a linear way
• A01

  • Sensory Register - briefly stored, coded in original form, brief duration, high capacity
  • Short-Term Memory - acoustic encoding, 18-30 second duration, limited capacity of 7+-2 items and transferred to LTM by rehearsal
  • Long-Term Memory - semantic encoding, unlimited duration, unlimited capacity
• A03

  • research support
  • Baddeley showed STM confuse similar sounding words and LTM confuses similar meaning words, shows they are separate
  • oversimplification
  • Shallice & Warrington found impaired STM but intact LTM so model undermines complexity
  • lack of focus on retrieval
  • modern models emphasise dynamic nature, MSM ignores interference and context-dependent, limits comprehensiveness and validity
