The Working Memory Model Flashcards
who made this model?
Baddeley and Hitch
what type of memory is it for?
short term memory
word-length effect
- capacity is determined by the length of time it takes to say the words
phonological similarity effect
words that sound similar are recalled less easily than those that are dissimilar
capacity of the phonological loop
limited capacity
what type of information does the phonological loop deal with?
auditory
what is the phonological loop subdivided into?
phonological store
articulatory process
phonological store
holds words heard
articulatory process
holds words heard/seen and silently repeated
like an inner voice (homunculus)
central executive - capacity
limited
where does information come from to go into the central executive?
encoded from the senses but cannot be held for long
functions of the central executive
to direct attention to tasks - decided what working memory pays attention to
determines how resources (slave systems) are allocated - makes decisions about which issues deserve attention and which should be ignored.
