L4 - working memory model (WMM):Multi-store memory model is over simplistic - describes LTM + STM AND SENORY REGISTER
as single units
Baddley and hitch (1974)
Focuses on STM - suggesting it has 4 different subunits
Each subunit = different role = focused on different types of information
Central executive (CE) phonological loop (PL) Visio-spatial sketchpad (VSS)
has a supervisory role = deals with auditory focuses on storing visual +
monitors any incoming information - refer to both spatial information
information from environment written + spoken words
and allocates information to 3 PL is divided into E.g. asked how many
further subdivision - phonological store and windows are in a room - you
necessary due to limited articulatory process visualise the room
duration and capacity of STM
Phonological store = stores Limited capacity of 3-4 items
Unfalsifiable the words we hear (baddeley 2003)
Articulatory process = what
allows maintenance rehearsal Logie (1995) can be further
- to keep information in our divided into visual cache
STM - repeats the words like (stores visual data ) and inner
an inner voice scribe (records the
arrangement of objects in our
Duration of loop is roughly 2 visual field)
seconds
Evidence for the PL :
Word length effect = people
can remember short words
compared to long words in
working memory because it
takes longer to say the words
than storage = inhibits / stops
rehearsal of the words =
more likely to forget /
remember less words =
shows evidence of limited
duration
