multi store memory model

• sensory register


  Where information comes into the brain from the senses

  Information is at the same format as its recieved

  Information from senses goes into the register, small amount is tended too

  Lasts for 2 seconds

  Capacity - unlimited

  Mode of representation- modality specific
• short-term memory


  Stores information in auditory form

  Information can last up to 30 seconds

  If information is rehearsed in STM it passes to LTM

  Any information not rehearsed is lost from STM

  Capacity : 5-9 chunks

  Mode of representation - auditory
• long-term memory


  Capacity : unlimited

  Duration : unlimited

  Mode of Use for representation - semantic but can also be acoustic or visual
• Displacement theory of forgetting


  A reason for forgetting, rehearsal loop in STM has limited capacity.

  Information from the model is not well recalled probably because it didn't go from rehearsal loop to LTM
• Displacement theory - primacy effect


  Information learned first is well remembered
• Displacement theory - recency effect

  Information learned last is well remembered
• interference theory of forgetting


  the theory that forgetting is caused by other memories impairing the retention or retrieval of the target memory.
• interference theory of forgetting - proactive interference


  When something learned earlier interferes with current learning
• interference theory of forgetting - retroactive


  Something learned later gets in the way of something learned previously
• Strengths of MSM


  - Supporting evidence

  - HM case study gives physiological support aswell as CW . Hippocampus hold STM

  - Shows they have separate stores - Baddeley conducted an experiment and found that semantic words were more difficult to recall, suggests encoding in STM and LTM were different
• Weaknesses of MSM


  - Experiments use artificial tasks, so might not be valid

  - Alternative explanations

  - Too simplistic an explanation , working memory was done to provide more knowledge

  - Emphasis given to rehearsal in transfer of information from STM to LTM
