The MSM is supported by research showing STM and LTM are different. |
BADDELEY (1966): found we tend to mix up similar sounding words when using our STMs. But we mix up similar meaning words when using our LTMs. THEREFORE, shows coding in STM is acoustic and coding in LTM is semantic. -supports MSM's view that STM and LTM are separate and independent. |
|
|
A limitation is that evidence suggests here is more than one type of STM. |
SHALLICE & WARRINGTON (1970): studied amnesia patient KF, who's STM for digits were poor when read aloud but recall better he read digits himself. -MSM states there's only one type of STM but KF suggests there must e one STM process for visual and another for auditory, THEREFORE, working memory model is a better explanation as it includes separate stores. |
|
|
A limitation is that it only explains one type of rehearsal. |
CRAIK & WATKING (1973): argue there are 2 types- maintenance and elaborative. BUT elaborative is needed for LTM (occurs when linking information to existing knowledge) THEREFORE, another research finding that can't be explained by the model. |
|
|
A limitation is research supporting MSM use artificial materials. |
PETERSON & PETERSON (1959): used consonant syllables with no meaning. - In everyday life we form memories relates to useful things (e.g. peoples names, faces etc.) THEREFORE, MSM lacks external validity as research findings do not reflect everyday life. |
|
|
A limitation is that MSM oversimplifies LTM. |
- we have one LTM store for facts about the world (semantic) - another for memories, like how to ride a bike (episodic) THEREFORE, doesn't reflect these different types of LTM. |
