MSM

• strength: research evidence Baddley 1966


  Point: The MSM shows that STM & LTM are different due to research evidence

  Evidence: Baddeley 1966 experiment found that we tend to mix up words with similar sounds when using out STM but mix up words with similar meaning when using LTM.

  Explanation: this shows that the STM stores acoustically and LTM stores semantically which means both types of memory have 2 different stores supporting the structure of the MSM.
• competing point: Campitelli 2015

  point: not all psychologists agree that the STM and LTM are entirely separate

  evidence: Campitelli 2015 suggested that the STM is part of the LTM and they aren't as separate as the MSM claims

  explanation: this challenges the MSM and the separation of the LTM and STM and the STM could be something we focus our attention on in the LTM.
• Weakness: the MSM only has one type of STM Shallece and warrington 1970

  Point: The MSM states there is only one STM and it encodes one way which is acoustically which is not the case

  Evidence: Shallace and warrington 1970 studied a patient with amnesia called KF who's STM for digits was poor when read aloud but when he read them to himself his STM was significantly better

  Explanation: this case study highlights that there may be multiple components to the STM like verbal and non verbal encoding which the MSM doesn't account for. its giving incomplete explanation
• application: improving memory

  point: the MSM has practical application to improving memory

  evidence: research shows that the limited capacity of the STM which is 7-9 items can be enhanced by chunking of 3. CAR LIP PEN

  explanation: this shows the usefulness of the MSM in helping individuals improve memory retention
