Memory - WMM

Question 1

Central executive

Answer 1

Drives WMM
Makes decisions and allocates slave systems to tasks
Limited processing capacity

Question 2

Phonological loop

Answer 2

Slave system
Deals with auditory info
Divided into 2 components:
Inner ear (holds info in speech based form for 1-2 seconds)
Inner voice (allows for maintainance rehearsal)

Question 3

Visuo-spatial sketchpad

Answer 3

Slave system
Stores visual and/or spatial info
Limited capacity (3 or 4 objects)

Question 4

Visio-spatial sketchpad

Answer 4

Slave system
Stores visual and/or spatial info
Limited capacity (3 or 4 objects)

Question 5

Episodic buffer

Answer 5

Slave system
Added to model in 2000
A temporary store of info
Integrates visual, spatial, and verbal info processed by other stores
Maintains sense of time sequencing
Limited capacity (4 chunks)

Question 6

WMM

Answer 6

Expansion of MSM
Develops concept of STM

Question 7

Which researcher support WMM
What did he do?
What did he find?

Answer 7

Baddely + Hitch (1973) - dual-task study

Ppts followed a spot of light moving in a circle while performing another visual or verbal task
Ppts performed badly on visual task BUT NOT on verbal task - VSS became overloaded by having to deal with 2 tasks, but verbal task made use of another store

STM has separate components for visual and auditory info

Question 8

Evaluate this research

Answer 8

✅Significant research suppport for existence of separate stores in STM
⛔️HOWEVER much of research highly controlled, artificial lab studies, or unrepresentative case studies - may undermine validity of support for model
⛔️Only concerns itself with STM - not much detail or insight into LTM, therefore not a comprehensive model of memory
