Psychology: Memory: Evaluation of the MSM

a) strengths

  • gives us a good understanding > of structure + process of STM > allows researchers to expand on this model - make it more valid and can prove what the stores actually do
  • the model is influential > generated a lot of research into memory
  • many memory studies provide evidence to support distinction between STM + LTM
  • model supports ==primary + recency effects==
  • case of HM supports the model > he was unable to encode new LTMs after surgery (hippocampus removal) but ==STM was unaffected==

  \

b) weaknesses

  • oversimplified > suggests that both LTM and STM operate in a single and uniform fashion (==this is not the case!!)==
  • both STM + LTM are more complicated than previously thought > ==Working Memory Model==
  • rehearsal > too simple to account for the transfer of info from STM to LTM > ignores factors such as motivation, effect, strategy
  • has been criticised for being a passive/linear model
