What are the components of Baddeley and Hitch’s (1974) Working Memory Model?
Central executive
Phonological Loop
Visuo-Spatial Sketch Pad
Episodic buffer
According to the WMM, what happens in task that uses 2 of the same component?
poor performance, takes up too much resources
According to the WMM, what happens in a task that uses 2 different components?
Good performance, as resources are spread
What is the main function of the central executive?
control & decision processes
What are the processes in the central executive?
Updating function
Shifting function
Inhibition function
What is the updating function in the Central executive?
updating of task at hand
What is the shifting function in the Central executive?
shifting between strategies
What is the inhibition function in the Central executive?
Selective attention
What is the main function in the phonological loop?
inner ear & voice, verbal rehearsal
What are the 2 parts of the phonological loop?
phonological store
articulatory loop
What is the purpose of the phonological store?
Passive storehouse
What is the capacity of the phonological store?
± 2 sec of speech
What is the purpose of the articulatory loop?
active rehearsal component
What is the phonological similarity effect?
Errors more likely to occur if items sound the same
What is the word length effect?
memory span for short words is greater than for long words
Why does the word length effect occur?
If articulation duration of a word is longer than 2 secs, it is less likely to be remembered.
What is the unattended speech effect?
Performance impaired if other verbal material needs to be ignored.
Why does the unattended speech effect occur?
Irrelevant spoken material can gain access to phonological store, harder to perform
What is an articulatory suppression task?
preventing rehearsal by overt or covert articulation
Why does articulatory suppression occur?
Taxes either the phonological store (auditory presented)
or the articulatory loop (visually presented)
What is the main purpose of the visuo spatial sketch pad?
inner eye, processing spatial, visual, and kinesthetic information
What are the 2 components of the Visuo-spatial sketch pad?
visual cache
inner scribe
What is the purpose of the visual cache?
process shape & colour
What is the purpose of the inner scribe?
process spatial & movement
