WMM
Created by Baddeley and Hitch
Not a unitary store
Active and not passive
Central executive
Directs attention to tasks and makes decisions and allocates tasks to the slave systems
Limited capacity
Attentional control
Phonological loop
Coding - acoustic
Capacity - limited
Phonological store - holds words heard
Articulary control process - inner voice
Visuo-spatial sketchpad
Capacity - 3 or 4 items
Logie (1995) - found the visual-cache (form and colour) and the inner-scribe (spatial relations)
Episonic buffer
Integrates information
A01 - Dual Task Technique - Baddeley and Hitch (1976)
Participants have difficulty doing two similar tasks because it overloads the phonological loop
A03 - Patient KF - strength
Suffered brain damage and had issues with his STM
Unable to recall acoustically - no phonological loop
Able to recall visual information - visuo-spatial sketchpad
Supports separation idea
Increases validity
A03 - CE and EB components are too vague - limitation
Poorly designed
How does it decide which information is relevant
EB lacks substantial evidence for how it combines verbal, spatial and long-term memory
Braver (1997) - participants were given a task involving the CE - as difficulty increases, attention changes
Low validity
A03 - Hunt (1980) - strength
Faster at processing information makes you better at complex decision making tasks
Oaring memory is time-limited, so information must be processed before it becomes decayed or disrupted
CE controls processing
Increases validity
