WMM (A01+A03) Flashcards
1
Q
what is working memory
A
- a limited capacity store for retaining information for a brief period (STM) while performing mental operations on that information
2
Q
why was the WMM developed
A
- said the MSM description of the STM store was too simplistic
3
Q
what are the 3 components of the WMM and briefly what do they do
A
- central executive supervises the system and controls the flow of information
- phonological loop which holds sound information
- visuospatial sketchpad which deals with visual and spatial information
4
Q
what is the dual-task paradigm
A
- if you complete 2 tasks that involve the same store than performance will struggle
- e.g. trying to listen to 2 conversations at once
5
Q
what is the function of the central executive
A
- drives the whole system
- allocates data/information to the correct sub-system
- helps with problem solving and mental arithmetic
- directs attention to tasks
6
Q
how is the central executive encoded
A
- through our senses
7
Q
what 2 stores is the phonological loop split into
A
- phonological store (inner ear)
- articulatory control process (inner voice)
8
Q
what is the function of the phonological store
A
- process speech perception
- stores auditory information (spoken words)
- gives memory of sounds
9
Q
what is the capacity of the phonological store
A
- 1-2 seconds (how many words you can say in 1-2 seconds)
10
Q
where can the phonological store retrieve information from
A
- sensory register
- long term memory
11
Q
what is the function of the articulatory control process
A
- process speech production
- maintenance rehearsal (in a loop format in the STM)
- subvocalising (speaking in your head)
12
Q
what is the capacity of the articulatory control process
A
- 2 seconds
13
Q
what is the function of the visuospatial sketchpad
A
- visual and spatial information
- navigation around environment
14
Q
what is the capacity of the visuospatial sketchpad
A
- 3-4 objects
15
Q
what did Logie (1995) to improve the visuospatial sketchpad
A
- subdivided the VSS into the visual cache (stores visual data) and the inner scribe (spatial information)
