wmm working memory model

Question 1

working memory model

Answer 1

alternative to multistore model
baddeley and hitch

argued stm = too simple , made up of different stores

Question 1

1s component of wmm

Answer 1

central executive
- main controller for whole system
- limited capacity , can’t store info

Question 2

2nd component

Answer 2

phonological loop

deals with auditory info ( acoustic coding)
has 2 parts
phonological store - stores spoken words
articulatory process - allows rehearsal of words

limited capacity

Question 3

3rd component

Answer 3

visual spatial sketchpad
deals with visual info ( what things look like), and spatial info ( where things are)
- stores temporarily

2 parts
visual cache - stores visual data like shapes and colours
inner scribe - stores spatial info ,helps you rmb where things are and how they move around you

limited capacity

Question 4

4th component

Answer 4

added in 2000 to wmm by baddeley
integrates info from ce pl and eb into ltm
Acts like temporary storage system with limited capacity

Question 5

strength, clinical evidence

Answer 5

p- clinical evidence, supports wmm
e- patient KF , poor verbal stm , but intact visual stm , = suggests damage to phonological loop , not visuospatial sketchpad
e- supports idea that wmm = made up of seperate components = only damaged one type of stm
l- wmm = real life evidence , shows memory = not unitary = strengthens validity

Question 6

strength , experimental research.

Answer 6

p- experimental research supports separate stores
e- baddeley found ppts could do visual and verbal tasks at the same time but not 2 verbal tasks
e- = verbal and vis info processed In different subsystems , supports model
l- strong experimental support , confirms assumptions

Question 7

limitation , vague

Answer 7

p- central executive not defined clearly
e- vague terms used to describe it e.g attention supervisory system, little explanation of what it acc does
e- difficult to test it and fully understand , some researchers say it consists of multiple components
l- model = lacks clarity = reduces explanatory power

Question 8

limitation , eb

Answer 8

p- eb, new , less researched part of wmm
e- added In 2000, to explain how info from vs, pl and ltm can be integrated
e- exact role, capacity, etc= unclear, difficult to test empirically
l- weakness model overall completeness , key component = poorly understood
