Working Memory Model Flashcards
Baddeley and hitch did what AO1
-proposed the wmm as explanation of how stm works
-stm not unitary store
-several diff stores
-all connected
-work independently
-as an active processor
-views mem as active rather than passive
Central executive AO1
-attentional process monitors incoming data
-decides what needs to be done nd when
-Delegates task according to slave systems
-code any type info
-keeps an eye on what’s happening in slave system takes over most demanding task
-new task requires attention will overload ce as it has very limited capacity
Phonological loop
-auditory info passed from ce to pl
-phonological store=store words hear inner ear
-articulatory loop= silently repeats words seen or heard
-limited capacity codes acoustically
Visuo spatial sketchpad
-visual info passed from ce to vss
-resp setting up images used to plan a spatial task e.g giving directions
-temporarily stores visual nd spatial info
-visual Cache= stores visual data
-inner scribe= records arrangement of objects in visual field
-limited capacity
-codes visually
Episodic buffer
To record event
-limited capacity
-code any type of info
Dual task performance
Two tasks at the same time that use the same slave system then performance is reduced cox they have limited capacity but not if they use different slave systems as there is no competition for limited capacity
Strength AO3
P-shallice and Warrington on patient kf suffered with amnesia
E-found kf recall poor when digits read aloud but better when he could visually see them
L-supp because sugg must be diff stores whiten stm one to process visual one for Auditory as the pl was damaged but vss intact
AO3 dual task performance
strength
P-supp notion there are separate components within stm nd have limited capacity
E-e.g baddely found ppt had diff when performing visual task at the same time as another visual task
E-than when performing one visual task alone or with verbal task
L-Because sugg both visual task competing for limited cap of same slave system whereas verbal and visual task simultaneously delegated to Sep slave system performance not reduced as no competition for cap credibility inc
AO3 limitation
P-opponents argue much of research conducted on PL and VSS
E- lack of clarity on role of CE said to be single component of attention that delegates to slave sys
E-however some psych sugg that ce may have several components within it
L-therefore doubts on WMM as an explanation of STM
