Mem: WMM AO1 Flashcards
What is working memory?
-a limited capacity store for retaining info for a brief time while performing mental operations on that info
-mostly replaced use of word STM from MSM- ‘working’ suggests mem is active not passive
Who created the WMM and why?
-Baddeley & Hitch (1974) believed STM was not a unitary store like MSM suggests
-argued it was an ‘active processor’ of info
What is the role of the CE?
-supervisory role-> doesn’t store info
-directs attention to tasks/makes decisions
-allocates tasks to slave-systems (sub-components)
-data arrived from senses or LTM
What capacity does the CE have?
Limited processing capacity
What is the role of the PL?
-processes info and recodes it acoustically
-can process info in any modality, but codes it acoustically
What capacity does the PL have?
-limited capacity of 2 seconds worth of info
What is the PL subdivided into?
-Baddeley (1986) divided it into:
-phonological store: holds words heard
-articulatory control process: inner voice (maintenance rehearsal)
What is the VSS subdivided into?
-Logie (1995) subdivided it into:
-visual-cache: stores info about visual items (e.g. form + colour)
-inner scribe: stores the arrangement of objects for spatial reasons
What is the word length effect?
-immediate memory span is better w/ short words than long words
-because short words can be articulated quicker, so more words can be silently practiced more before they decay
(Baddeley et al. 1975)
What is the role of the VSS?
-processes info and recodes it visually/spatially
-can take in info in any modality, but is recoded visiuospatially
-spatial= relationships between things
What is the capacity of the VSS?
-limited
-3-4 items
What is the dual task technique?
-tasks where performance is measured as ppts do two tasks at the same time
-Baddeley et al’s (1975) model found if one store is used for both tasks, performance is poorer- store’s limited capacity
-if tasks are using same parts of same component processing will slow
What is the role of the EB?
-temporary store which integrates info from other slave systems
-Baddeley (2000) added it later- realized model needed a more general store bc slave systems deal with specific types of info + CE has no storage capacity
-maintains time sequencing (records events happening)
-sends into to LTM store
What capacity does the EB have?
-limited capacity
-approx. 4 chunks
