Working Memory Model
(Baddeley & Hitch, 1974)
central executive
role:
- controls attention
- coordinates slave systems
- monitors overall memory store
- allocates cognitive memory tasks
exam mark scheme description:
The central executive is said to control the subsystems while also being involved in tasks such as problem solving and attention
Eslinger and Damasio (1985):
After someone had a brain tumour removed, reasoning tests showed they had an intact CE, yet had poor decision making. CE could be multiple parts
too vague and simplistic, does not explain much
most of the info about the CE is from brain damaged patients, so we can't make before and after comparisons, brain damage is also traumatic so may be why behaviour changed
visuospatial sketchpad
exam mark scheme description:
The visuospatial sketchpad is a subsystem that processes visual input such as images or light, and spatial information such as direction
-
Darling et al (1993) spatial and visual tasks:
30 black & white squares, one with a P in it. Ppts asked to recall appearance or position of the P. They were then given either visual or spatial interference. Visual interference did not affect spatial recall and vice versa. Shows vssp as separate units
Lieberman (1980) blind people:
VSSP implies spatial info was first visual info. Blind people have good spatial awareness but no visual info. VSSP should be two stores
phonological loop
exam mark scheme description:
The phonological loop processes auditory information using the articulatory control to subvocalise and the phonological store to temporarily hold sound
-
-
phonological store
auditory information enters, only stored for 1-2 seconds if it doesn't go to articulatory loop
-
Paulesu et al (1993) PET scans:
Scans show the Broca's area (speech area) active during sub vocal rehearsal and supramarginnal gyrus (language processing) active when phonological store is used
