MULTI STORE MODEL

• who created the MSM?

  Atkinson and Shiffrin (1968)
• what are the three main stores?

  sensory register, STM + LTM
• draw the diagram


  draw a diagram

  
• what is the coding, capacity and storage of the sensory registor?

  - depends on the sense being used

  - very large capacity

  - 1/2 second duration
• what is the coding, capacity and storage of the short term memory?

  - acoustic

  - holds 5-9 items

  - 18-30s duration
• what is the coding, capacity and storage of the long term memory ?

  - semantic

  - holds unlimited

  - permanent
• Explain Murdocks study - serial position curve

  in the Murdock serial position curve experiment, participants are presented with a list of words and then asked to recall them in any order. Murdock found that words presented at the beginning (primacy) and end (recency) of the list were better remembered than those in the middle. This reflects the primacy effect (due to rehearsal of words at the beginning) and the recency effect (due to words at the end being in short-term memory).
• Clinical evidence - Clive Wearing

  he got a viral infection in his brain which led to having amnesia

  - 30s memory

  stm is fully damaged

  ltm is partially damaged
• AO3: Weakness - artificial materials

  the use of artificial materials in msm studies include using word lists and meaningless tasks

  this is not reflective of remembering in real life so this manner of assessment isn't valid

  lacks external validity
• AO3: Weakness - oversimplifies LTM

  large amount of evidence to suggest LTM isn't a unitory store

  other research such as clive wearing suggests we have different types of ltm - episodic, semantic, procedural
• AO3: strength - practical structure

  the structure of the model makes it easy to conceptualise and investigate different aspects of memory

  the clear structure allows researchers to apply to their research
