WMM Flashcards
working memory model
baddeley and hitch
- the part in your memory you’re using when you are working on something
examples of working memory
calculating a complex sum or reading a sentence
why is STM not just one single store
- if you do 2 things at the same time, and are both tasks of the same sort, then you will perform them less well
- if you do 2 things at once and one task is visual and the other involves sound, then there is no interference
- you do them as well simultaneously as you would seperately
- so suggests that we have 1 store for visual processing and 1 for processing sounds as the WMM suggests
the central executive
- overall control of other 3 slave systems
- directs attention to a particular task and monitors incoming data
- makes decisions and allocates data to each slave system dependent on data type
- very limited capacity, cannot attend to too many things at once and has no capacity for storing information or data
the phonological loop
- deals with auditory info and preserves the order in which info arrives
- has a limited capacity and coding is acoustic
two subdivides of the phonological loop
- the phonological store
- the articulatory process
the phonological store
passive store of words you hear in your inner ear
the articulatory loop
active rehearsal system-allows maintenance rehearsal, capacity of the loop is believed to be 2 seconds of what you can say-known as inner voice
the visuo-spatial sketchpad
- stores visual and spatial info
- visual info is what things look like; spatial info is the relationship between things
- capacity is approximately between 3-4 objects
two subdivides of visuo-spatial sketchpad
- visual cache
- inner scribe
visual cache
stores visual data
inner scribe
records the arrangement of objects in the visual field
episodic buffer
- added later to the original model
- temporary store for information integrating verbal, visual and spatial info
- integrates from CE,VSS, PL
- it maintains a sense of time sequencing
- limited capacity; 4 chunks
- sends info to LTM
limitation: little information
- little information provided about the functioning of the central executive
- it has limited capacity but does not explain what the limitations are
- it is a modality free processing component but precise details have not been provided
limitation: no clear explanation
- no clear explanation of how the three working memory components interact together
