memory-multi-memory model Flashcards
who came up with the multi-store memory model ?
Atkinson and Shiffrin (1968)
what does Atkinson and Shiffrin state
they state that the multi-store memory mode is made up of the sensory register, short term memory and long-term memory
how are memories formed?
memories are formed sequentially and the info passes from one component to the next in a linear fashion
what type of model is this?
linear model
what does the term capacity mean in memory
capacity is the amount of information that can be held (the volume of info)
what is the capacity for short term memory according to Miller ?
capacity for short term memory is 7+/- 2, this is because we remember things in groups of 7.
Concept of “chunking “
what is the capacity of long term memory
unlimited
what is the capacity of the sensory register
unlimited
what does the term coding mean in memory
coding is the format in which the memory is recalled
how does STM code
acoustically
how does LTM code
semantically
how does sensory register code
through the 5 senses
what study states coding STM and LTM are two different stores
Baddeley in 1966
what does Baddley’s study state in terms of acoustic coding
states that more mistakes are made when recalling acoustically - similar words straight after.
what does Baddley’s study state in terms of semantic coding
states that when recalling words more mistakes are made when recalling semantically- similar words after 20 in of learning them
what does the term duration mean in memory?
duration is how long the memory is held for
what is short term memory duration
18 sec
long term memory duration
unlimited
what is maintenance rehearsal
maintenance rehearsal involves the process of linking new info in a meaningful way
key study Peterson and Peterson
This study was done in 1959. Its aim is to investigate how different short intervals containing interference task affect the recall of items presented verbally to asses duration of STM
what is a strength for the working memory model
support study
A support study is the one done by Baddley in 1966 which states that the LTM codes sematically ( words are learned through meaning) an that the STM code acoustically (words that sound the same). This then clearly shows that the two are two different stores supporting the idea of thet MSM.
