The multi-store model MEM Flashcards
the multi-store model
representation of how memory works in terms of three stores
sensory register
the memory stores for each of our five senses.
who created the multi store model?
Atkinson and Shiffrin
examples of modality specific coding
Visual → iconic memory
Acoustically → echoic memory
Duration in sensory register
less than half a second
capacity in sensory register
very high
When does information pass further into the memory system
when you pay ATTENTION to it
+psychologists
STM coding, duration, capacity , type of store
- accoustic (baddeley)
- 18s(peterson and peterson)
- limited capacity (miller)
- temporary store
When does maintenence rehearsal happen?
when we rehearse information and if we do it for long enough the information passes into the long-term memory.
LTM coding, duation, capacity, type of store
- semantic (baddeley)
- potentionally permenant
- unlimited
- permenant
When we want to recall information from LTM, it has to be transferred back into STM by ………..
retrieval
where does some of the strongest evidence for the multi store model come from
serial position effect studies and studies of brain-damaged patients.
Murdocks procedure
Murdock presented participants with lists of 10 to 40 words, one word at a time, at a rate of one word per second. After the list was finished, participants were asked to recall as many words as they could in any order.
Murdocks results
The probability of recalling any word depended on its position in the list (its serial position).
Words presented either early in the list (the primacy effect) or at the end of the list (the recency effect) were more often recalled
Ones in the middle were often forgotten
Murdocks conclusions
words early in the list were put into long term memory (primacy effect) because the person has time to rehearse each word acoustically.
Words from the end of the list went into short term memory (recency effect).
Words in the middle of the list had been there too long to be held in short term memory (STM) (due to displacement) and not long enough to be put into long term memory (LTM). This is referred to as an asymptote
