Evaluating Short And Long Term Memory

Question 1

CAPACITY
STM’s capacity may be even more limited:
Cowan (2001) -

Answer 1

it’s more likely to be limited to 4 chunks as research showed 4 as the limit and thus ‘7-2’ is more accurate

Question 2

DURATION
STM may be due to displacement:
Reitman (1947) -

Answer 2

used auditory tones so that displacement wouldn’t occur and found that the duration of STM was longer suggesting that forgetting in Peterson’s study was due to displacement rather than decay

Question 3

CODING
LTM may not be exclusively semantic:
Frost (1972) -

Answer 3

showed that LT recall was related to visual as well as semantic categories and so LTM cannot be restricted to just semantic coding
