theories Flashcards
who created the multi store memory model ?
Atkinson and Shiffrin 1968
what is the first store in the MSMM ?
sensory register
how does information enter the sensory register ?
by a stimulus from the environment
how is information taken into the sensory register ?
it is encoded
how long does information last in the sensory register ?
2 seconds
how is information stored in the sensory register ?
as senses
what is the capacity and duration of the sensory register ?
unlimited, but information is lost very quickly
why is information lost quickly in the sensory register ?
we don’t pay attention to it
how is information lost in the sensory register ?
via decay
where does the sensory register lead to ?
short term memory store
how is information transferred from the sensory register to the stm ?
information we pay attention to
how are memories encoded in stm
acoustically
how long do stm memories last ?
up to 30 secs
what is the capacity of stm ?
around 7 chunks
how is information kept in the stm
maintenance rehearsal
how is memory lost in stm ?
displacement
how does information transfer from the stm to the ltm ?
elaborative rehearsal
what is elaborative rehearsal ?
information is repeated acoustically or linked to something we already know
how is information encoded in ltm ?
by attaching meaning to the information
what is the capacity of the ltm ?
unlimited
what is the duration of the ltm store ?
unlimited
how does info transfer from ltm to stm ?
retrieval
how is information lost in stm ?
decay or interference
who created the working memory model ?
baddeley and hitch 1947
what type of memory does the working memory model focus on ?
short term memory
what are the different components of the working memory model ?
phonological loop
central executive
visuospatial sketch pad
episodic buffer
what is the central executive ?
- the central control system which has a supervisory role
what does the central executive do ?
monitors incoming data and makes decisions about which of the 2 subsystems it should be placed into
carries out attentional processes of our memory system
focused divides and switched attention to different stimuli
what is the phonological loop ?
- deals with auditory and language based information
- preserves the order in which information arrives
what are the 2 sections of the phonological loop ?
- phonological store
- articulatory processes
what is the phonological store ?
stores auditory information and gives memory of sounds
what is the articulatory process ?
maintenance rehearsal in loop format, subvocalsing happens here
how many seconds of information does the articulatory process hold ?
2 seconds
what is subvocalising ?
your inner voice - repeating things to yourself
what is the visuo spatial sketch pad ?
stores visual and spatial information
what is the capacity of the visuo spatial sketch pad ?
- 3-4 objects
what are the 2 modalities of the visuospatial sketch pad ?
- visual cache
- inner scribe
what is the visual cache ?
visual storage system which retains all data inputted via your visual sense
what is the inner scribe ?
records arrangement of objects within a visual field allowing rehearsal of spatial information
when was the episodic buffer added ?
2000
what is the episodic buffer ?
a temporary store that intergrates acoustic visual and spatial information
what does the episodic buffer do ?
maintain a sense of time
what is the episodic buffers capacity ?
4 chunks
what are the 2 sections of Tulvings long term memory ?
episodic memory
semantic memory
