working memory model
central executive
-
-
focuses, switches and divides our attention
-
-
-
episodic buffer
integrates visual, spatial and auditory info
maintains a sense of time sequencing, records events (episodes)
-
-
evaluation
application to understanding amnesia: KF, poor STM for auditory info but could process visual info
KF unique individuals- case study- difficult to replicate and low validity in findings, cautious in generalising findings
support from lab experiments- Baddeley found that pp who performed a visual and verbal task together, performance on each was no worse than when carried out separately, no competition between slave systems
phonological loop
articulatory process
allows for maintenance rehearsal, repeats so can be stored in phonological loop. 'loop' said to have capacity of how long it takes to say 2 things
-
visuospatial sketchpad
-
inner scribe
stores arrangement of objects in visual field,

claims
short term memory is separated into 4 components where each component is qualitatively different in terms of encoding and capacity.
