Zusammenfassung der Ressource
Memory- working memory model
- Central executive
- Coordinates activity of
other subsystems, as
well as allocating
resources
- Very limited capacity
- Visuo-spatial sketchpad
- Visual and spatial information
- Limited capacity
- 3-4 objects
- The visual cache
- Stores visual data
- The inner scribe
- Records arrangement of objects
- Phonological loop
- Auditory information
- Acoustic coding
- Phonological store
- Stores the words you hear
- Articulatory process
- Maintenance rehearsal of
words in a 'loop' to keep
them in the STM as long as
necessary
- 2 second capacity
- Episodic buffer
- Integrates all information
and ensures time sequencing
- Limited capacity
- 4 chunks
- Links WM to LTM
- Evaluation
- Clinical evidence
- Patient had trouble with auditory
information processing but fine for visual
- Damage to phonological loop but
not visuo-spatial sketchpad
- Suggests they are separate stores
- Difficult to generalise
- Often deals with patients with
unique cases, sometimes
revolving around trauma
- Dual task performance
- Baddeley
- More difficult to do two tasks in the same
store (e.g. visuo-spatial tasks) compared to two
different tasks (e.g. auditory and visual)
- Suggests there must be separate
subsystems to deal with auditory
and visual information
- Lack of clarity over central executive
- Not a full explanation of STM
- May have separate components
- Word length effect
- List of long words more
difficult to remember
- 2 second capacity in articulatory process
- Brain scan studies
- High levels of activity in the left
pre-frontal corex during CE activity
