central executive
filters information to determine which information received by the sense organs is and isn’t attended to
capacity of the central executive
limited (4 items)
phonological loop
processes auditory (sound) information
capacity of the phonological loop
words that are said in 2 seconds
primary acoustic
the inner ear. holding words recently heard
articulatory process
the inner voice. Hold information via sub-vocal repitition
Visio-spatial sketchpad
processes visual and spatially coded information
visual cache
A passive store of form and colour
inner scribe
active store holding the relationship between objects in 3D space
episodic buffer
A temporary store of integrated information by the Central executive, phonological loop, Visio-spatial sketchpad and Long term memory
Evidence that the PL and VSS are separate: Baddeley (1975)
- PPTS were asked to perform two visual task
- They were asked to track a moving light and describe the angles of the hollow letter f
- The task was hard as both tasks require the VSS
Evidence for PL capacity
- PPTS was visually shown a word list and then asked to write them down in the same order
- One condition had monosyllabic words like bond and yield
- the second condition had polysyllabic words like opportunity
- PPTS can recall more monosyllabic words than polysyllabic words
- This suggest that the capacity of the PL is the time it takes to say the word
WMM AO3: inferences
Models of the memory cannot be directly observed so researches have to make inferences on the structure of memory based on behaviour observed during experimentation. These inferences could be incorrect.
