MSM

HideShow resource information
Atkinson and Shiffrin (1968)
creators of the MSM, three separate stores that differ in capacity, duration and encoding
1 of 9
Miller (1956)
magic number 7 +/-2- this is how many chunks of information one can keep in the short term memory
2 of 9
Murdock (1962)
primacy and recency effects, remember the first couple and the last couple of pieces of information e.g. in a word list
3 of 9
Sperling (1960)
ppts saw a grid of letters for 50 milliseconds- asked to recall as much as they could, average 4/5 letters- dedicated a high, med or low tone to the rows and when asked to recall a row after hearing the tone recall dropped to 3 letters
4 of 9
Peterson and Peterson (1959)
gave participants a number of codes to remember (numbers and letters), recall after 3 seconds was 90%, recall after 18 seconds whilst being asked to count backwards from 100 in 3s was 2%
5 of 9
Bahrick et al (1975)
asked about classmates from high school- had to put a name to the face- 48yrs later ppts were 70% accurate- shows memory can be long term when it's meaningful
6 of 9
Baddeley (1966)
found that encoding acoustically similar words in the STM was more difficult than in long term, whereas semantically similar words posed no problem for the short term but cause muddles in the LTM
7 of 9
Baddeley and Hitch (1974)
working model of memory proposes that there are more stores to the STM not just one as the MSM suggests
8 of 9
Logie (1999)
LTM and STM work together so the MSM is wrong by saying that the STM comes before the LTM as they rely in each other- too reductionist
