Research into capacity of stm |
Baddeley et Al. How word length effects stm. Participants could remember shorter words better. Didn't reflex everyday life. Unrelated words. |
|
|
Duration of stm research |
Peterson and petersons trigrams 3 letters. After interval asked to recall trigram. Rehearsal prevented . 3 seconds-80%recall 18 sec -less than 10% Doesn't reflect everyday life. Interference could've cause results not recall |

|
Stm encoding research |
Baddeley Participants put into four groups Acoustically similar words Acoustically dissimilar Semantically similar Semantically dissimilar After hearing five words asked to recall in order. Acoustically similar harder to recall Stm reliant on acoustics of words Study doesn't reflect complexity of encoding Supports conrads study |

|
Long term duration research |
Bahrick 392 graduates shown year book photos. Select photo of name given. Two groups; recognition and recall. Recognition :60% after 47 years Recall :less than 20% after 47 yrs Ecologically valid Doesn't reflect decline in memory due to age |

|
Support for msmm |
Glanzer and cunitz Serial positioning effect First words go into ltm as they're rehearsed Last words go into stm as they're last heard and middle forgotten Too simplistic Shows two separate stores |
|
|
Kf shallice and warrington |
Ltm unaffected stm only remembers 2-5 items. Proves msmm wrong as he is unable to rehearse stm but can still make ltm |
|
|
Cohen and squaire |
Added procedural to how memory is encoded. Clive wearing only remembers procedural ltm |
