Q

phonological loop

A

WMM - auditory coding, holds info like words, number

Repeating info over and over in a loop to keep in STM or transfer to LTM (sub-vocal repetition)

Q

visuo-spatial sketchpad

A

WMM - where visual and spatial info is stored

17
Q

STM and LTM coding research

A

Baddeley - 75 pps, 4 conditions, 5 words in each list that are: acoustically similar, acoustically dissimilar, semantically similar and semantically dissimilar
When immediately recalling (STM): pps did worst with acoustically similar (55% accuracy)
When recalling after 20 mins (LTM): pps did worst with semantically dissimilar

18
Q

STM capacity research

A

Jacobs digit span test - pps immediately recall either sequence of letters or numbers which increases in length by one each time and they continue until they can’t correctly recall the sequence. Letters roughly 7 on average and numbers roughly 9, suggesting STM capacity is around 5-9 or 7+/-2
Miller recognised the idea of ‘chunking’ info to make what would have been multiple pieces of info into just 1 in order to increase capacity

19
Q

MSM weaknesses

A
  • rehearsal not necessarily required for LTM
  • ‘deep processing’ states learning info well with more meaning more likely to be lasting so criticises rehearsal as too simple
20
Q

MSM comparison to WMM

A

MSM more complete as includes all STM and LTM but WMM more complex as more detailed, in depth STM

21
Q

Outline MSM

A
  • Atkinson and Shiffrin
  • how info moves from one store to another of 3 unitary stores (sensory register, STM, LTM)
  • features of each
  • attention: info from sr to STM, if not then decays
  • maintenance rehearsal: acoustic repetition to keep in STM or move to LTM otherwise decays
  • retrieval: LTM info brought into STM to use
22
Q

LTM capacity research

A
  • Linton
  • diary recording 7 years recalling 11000 events with a cue word for each
  • when tested with cue words she recalled with about 70% accuracy
  • huge LTM capacity
23
Q

LTM capacity evaluation

A

Linton

  • good ecological validity as test of everyday memory so not artificial
  • bad population validity as case study so unique to her and her memory will differ from others so can’t be generalized to all
24
Q

STM capacity evaluation

A
  • good internal validity as controlled lab experiment
  • reliable can be replicated as standardised procedure
  • bad ecological validity as not a fair test of everyday memory
25
Q

Coding evaluation

A

Baddeley

  • good internal validity as lab experiment, controlled environment
  • lack of ecological validity as not valid test of everyday memory
26
Q

STM duration research

A

Peterson + Peterson

  • 24 psychology students
  • nonsense trigrams, count backwards from 30 in threes to prevent rehearsal
  • recall trigrams after 3 seconds
  • Interval increase by 3 seconds each time
  • 80% recalled after 3 seconds, 10% after 18 seconds
27
Q

STM duration evaluation

A

Trigrams

  • good internal validity as lab experiment
  • limited sample as opportunity sampling not representable of whole target population so not fully generalisable
