Multistore model Flashcards
The ___________ model
Atkinson and shiffrin 1968
Memory store order in the MSM
Environmental stimuli> sensory register> short term memory>longterm stimuli
2 main sources of stimuli
modality specific - echoic and iconic
coding, duration, capacity of the sensory register
coding - Modality specific
duration - iconic is 250ms and echoic is 3-4 seconds
capacity - unlimited
Coding
Transforms incoming information into a form that can be stored in memory.
Duration
The length of time the memory lasts before it is forgotten
Capacity
The amount of information that the store can hold.
coding, duration, capacity of the STM
coding - acoustic
duration - 18-30 seconds
capacity - 7 +/- 2
coding, duration, capacity of the LTM
coding - semantic
duration - unlimited
capacity - unlimited
what is Georges magic number 7 and what does it research and who made it
Things often come in sevens, (7 days, 7 deadly sins) and it is research on the capacity of stm, george miller
what is the digit span, what does it research and who made it
give pp 4 digit number, pp must recall. Then give pp 5 digit number. research on capacity in STM and Joseph Jacobs
what is the research done for coding in the STM and LTM
Alan Baddeley (1966) 4 groups acoustically and semantically similar or dissimilar words. Shown the words then asked to recall instantly and after 20 minutes.
Findings of coding in the STM and LTM
did worse with acoustically similar words when recalled instantly. This shows STM is coded acoustically. did worse with semantically similar words when asked 20 minutes later. Shows that LTM codes semantically.
