Multi store model of memory evaluation

Strengths of MSM (capacity)

capacity of the stores are different (Sperling, Joseph Jacobs, Standing et al)

Strengths of MSM (brain damage)

support for distinction between STM and LTM stores from patients with brain damage (HM, KF, Clive Wearing)

Strengths of MSM (encoding)

supports for notion that encoding is different in STM and LTM (Baddeley, Crowder)

Strengths of MSM (duration)

huge differences in duration have been found (Peterson and Peterson, Bahrick)

Weaknesses of MSM (info processing)

assumed that info is processed in STM before LTM which is too simplified

Weaknesses of MSM (encoding)

assumed info in STM is encoded acoustically and LTM semantically, oversimplified (how does it change from sound to meaning)

Weaknesses of MSM (LTM)

LTM is simplified because procedural and declarative memory is not accounted for

Weaknesses of MSM (STM)

STM is simplified because there is evidence from brain damaged patients that there are number of STM stores (KF)

Weaknesses of MSM (info transfer)

argues that the transfer of info from STM to LTM is through rehearsal (how much do we actually do of this in real life)
