the Working Memory Model Flashcards
What is the central executive
⚫️processes info from all sensory routes
➡️controls slave system
➡️process is attention like
➡️limited capacity
Who made the WMM
➡️Baddeley & Hitch
➡️replaced the idea of a unitary STM
➡️suggests a system involving active processing
➡️and short-term storage of information
➡️Baddeley and Lewis
➡️added episodic buffer stock
Give a research study if the central executive
⚫️Baddeley
➡️participants could not generate random numbers
➡️whilst switching their attention between letters and numbers
➡️suggesting that two task were competing for central executive resources
➡implies CE has limited capacity
➡️can only handle one info at a time
Describe the phonological loop
⚫️part of slave system
⚫️processes on auditory info
⚫️limited capacity determined by
➡️how much info is spoken aloud in around 2 sec
Describe the 2 sub parts baddeley divided the PL into
⚫️phonological store
➡️focusses on incoming speech
⚫️articulatory process
➡️focusses on speech production
Give a research study to support the phonological loop
⚫️Baddeley et al
➡️found participants recalled more shorter words
➡️than longer words
➡️suggesting
➡️capacity of phonological loop
➡️determined by how long it takes to say words
➡️rather than number of words
Describe the visual-spatial sketchpad
⚫️process of
➡️spatial and visual info
⚫️visual cache
➡️stores visual material about form and colour
⚫️inner scribe
➡️stores info about spatial relations
Give a research study of visual-spatial sketchpad
⚫Klauer & zhao
➡️suggest more interference between two visual task
➡️than between a visual and a spatial task
➡️suggest existence of separate visual cache and inner scribe
Describe the episodic buffer
⚫️limited capacity store of integrated info ➡️from ➡️central executive ➡️phonological loop ➡️visual-spatial sketchpad ➡️LTM
Give a positive evaluation of the WMM
⚫️braddeley found
➡️patients with damaged frontal lobe
➡️had problems concentrating
➡️suggesting damage to the central executive
Give two negative evaluation of the WMM
⚫️central executive too simple
➡️important part of model
➡️but exact role is unclear
⚫️braddeley added the episodic buffer ➡️making model more complex ➡️suggest model is not complete ➡️may need more further revision ➡️as still more evidence is uncovered
