Working Memory Model

Question 1

who proposed the WMM

Answer 1

baddeley and Hitch

Question 2

what is the WMM

Answer 2

explains memories related to working on tasks that require immediate memory info

Question 3

four components of the WMM

Answer 3

Episodic buffer
Visuo-spatial sketchpad
Central executive
Phonological loop

Question 4

what is the role of central executive

Answer 4

focus attention on the most important task that need to be done at present moment
coordinates the three other components
limited capacity and cant store info

Question 5

the phonological loop

Answer 5

responsible for coordinating auditory info
coding is acoustic
two divisions

Question 6

the two divisions in the phonological loop

Answer 6

phonological store: stores spoken words (the inner ear)
articulatory process: stores written words (inner voice)

Question 7

visuo-spatial sketchpad

Answer 7

responsible for storing visual spatial info
info stored temporarily
limited capacity
divided into visual cache: visual data
inner scribe: arrangements of objects

Question 8

role of episodic buffer

Answer 8

integrates info from other three components into time-sequenced eps
stores info temporarily
limited capacity
separate from LTM crucial for long term episodic learning

Question 9

WMM AO3: KF case study supports

Answer 9

KF had a brain injury affecting STM.
Struggled with verbal/auditory info but retained visual recall ability.
Supports the WMM’s idea of separate slave systems for verbal/auditory (phonological loop) and visual (visuo-spatial sketchpad) processing.

Question 10

WMM AO3: dual task performance effect

Answer 10

baddeley got ppl performing a digit span task ( repeating numbers) and verbal reasoning (answering true/false questions) ]
