- Models of Memory
- Multi store memory model
- Atkinson and Shiffrin 1971
- memory consists of three
memory stores
- Sensory
store
- duration: few
seconds
- don't pay attenion to the
new info, will decay
- first store- info from
sensory input
- duration: few
seconds
- Short term
memory
- duration: max 30 secs
average 18 secs
- PETERSON AND PETERSON 1959
- presented trigrams through headphones
- distraction task- avoid rehearsal-
ensure testing STM
- count backwards from 100 in threes
- count backwards from 100 in threes
- distraction task- avoid rehearsal-

- findings
- retention interval increased=
percentage correct decreased
- at 0 secs, correct was 90%
- at 18 secs, correct was 5%
- retention interval increased=
percentage correct decreased
- presented trigrams through headphones
- PETERSON AND PETERSON 1959
- capacity: 7+-2 items
- JACOBS 1890
- investigated serial
digit span
- precisely presented
an item every half
