Atkinson & Shiffrin
- capacity
- short term memory
- Joseph Jacobs
- found average
recall to be 7+-2
items
- presented numbers
and asked for
immediate recall
- lacks mundane
realism - lab study
- this would mean we are
unable to remember
words longer than 9
letters
- so miller said out stm can
hold 7+-2 chunks of
information, and personal
experience would determine
what was a meaningful chunk

- found average
recall to be 7+-2
items
- the recency effect
- you remember the
most recent chunks
more than others
- this is not always the case
- you remember the
most recent chunks
more than others
- Joseph Jacobs
- long term memory
- the capacity is hard to measure
- it seems to be infinite
- some people seem to be able to recall
lots of detail for many years, other
people not so much
- the capacity is hard to measure
- short term memory
- duration
- short term memory
- Peterson & Peterson
- used trigrams to test
stm duration
- found worse recall
after longer delay
- memory in stm is
fragile and easily
forgotten
- lacks mundane realism
- doesn't account for the
duration of pictures, sounds or
smells
- used trigrams to test
stm duration
- Peterson & Peterson
- long term memory
- Bahrick et al
- found 90% accuracy for recalling faces
and names 34 years after leaving
school, and 80% accuracy for names
and 40% for faces 48 years after leaving
school

and 40% for faces 48 years after leaving

- ltm duration is possibly infinite
- hard to test = just because you can't
think of something at the time doesn't
mean its been forgotten
- Bahrick et al
- short term memory
- encoding
- Baddeley
- stm is acoustic coding
- worse recall if the words sound similar
- worse recall if the words sound similar
- ltm is semantic coding
- worse recall if words have similar meanings
- worse recall if words have similar meanings
- did not take account of visual cues
- Posner
- said that visual information is important.
it is easier to identify A and A as being
the same as A and a
- said that visual information is important.
it is easier to identify A and A as being
the same as A and a
- stm is acoustic coding
- Baddeley
- evaluation
- strengths
- defines stm and ltm
- evidence from different encoding
- definite differences in capacity
between stm and ltm
- different durations in stm and
ltm been proven
- defines stm and ltm
- weaknesses
- overemphasis on rehearsal.
maybe in lab but too consciously
in real life
- lacks description. how does info
go from acoustic to semantic
coding?
- info probably contacts ltm before
rehearsal in stm, this is not explained
by model
- reductionist and oversimplified
- overemphasis on rehearsal.
maybe in lab but too consciously
in real life
- strengths
