multi store memory model Flashcards
theoretical model
representation of how something looks/works
what is memory
process or storing/retrieving info
what is coding
format memory is stored
what is capacity
how much info a memory can retain
what is duration
how long store can retain info for
what are the three stores of memory
sensory register (SR)
short term memory (STM)
long term memory (LTM)
what is the sensory register
hold info from 5 senses
what is short term memory
.info we are currently aware of/thinking about.
.This info comes from paying attention to sensory register
what is long term memory
.How we retain info about events that have happened in the past.
.info remains here permanently
what is coding/capacity/duration of sensory register
.sense specific
.Large(4 items)
.limited (miliseconds)
what is coding/capacity/duration of short term memory
.acoustic
.5-9 chunks
.18-30 seconds
what is chunks
chunking means making info more meaningful by organising it in line with info already in LTM
what is coding/capacity/duration of long term memory
.Semantic
.unlimited
.Years of life
what do most studies into msm lack
ecological validity
(except Bahricks)
what did murdock do
read list of words to ppts and asked them to recall as many as possible
what is the primacy effect
(Murdock)
words first heard were rehearsed and so can be can be recalled from LTM
what is the recency effect
(Murdock)
words heard last and can be recalled from the STM
what is cognitive neuroscience
study of how brain/mind relate
who is Clive Wearing
suffered brain infection giving retrograde/anterograde amnesia.
could use STM for 20 seconds but not able to transfer memories to LTM
what is retrograde/anterograde amnesia
(Clive Wearing)
retrograde- cant recall past memories
anterograde- cant form new memories
why does Clive Wearing support msm
couldn’t transfer memories from STM to LTM which helps suggest that transference is essential to the msm
How do memories get from STM to LTM
By doing elaborative rehearsal memories can be transfered to the LTM.
what does maintenance rehearsal do
keeps stuff in STM
what does Elaborative rehearsal do
Transfers stuff to LTM
