Working memory model Flashcards
what is the working memory model
alternative to msm that only focused on STM arguing that it must be more complex and it has a number of different stores
who came up with working memory model
baddeley and hitch
what does the central executive do
manages and organises information that arrives from the senses into the three slave systems
what are the five parts of the wmm
- central executive
- visuo-spatial sketch pad
- episodic buffer
- phonological loop
- long term memory
what are central executive characteristics
- decides what data is and isn’t attended to
- limited capacity and no capacity for storing data
- attains a balance between tasks when attention is needed
what does phonological loop do
deals with auditory information and their order(the order in which words occur)
what are characteristics of phonological loop
-limited capacity- 2 seconds with id auditory info
what did Baddeley find
- ppts recalled more shirt words in order that long words
- support idea that capacity of PL is determined by how long it takes to say the word rather than the actual number of words
what is the visuo spatial sketch pad
temporary store for visual and spatial info
what is visual information
what things look like
what is spatial information
the physical relationship between things
what does visuo spatial sketch pad do
help us navigate and interact with our physical environment
what is the episodic buffer
stores info that cannot fit into VSS and PL
what are the characteristics of episodic buffer
- a store that integrates the CE,PL and VSS
- temporarily stores info from all three
- holds info that relates to both visual and acoustic information and send info to LTM
what was supporting research for WMM
using brain damaged patients
- study’s on a man whose STM forgetting of auditory info was greater than this forgetting of visual stimuli
- his brain damaged seemed to be linked to only phonological loop
