WMM

Question 1

what are the 4 components of the WMM?

Answer 1

central executive
episodic buffer
phonological loop
visuo-spatial sketchpad

Question 2

what does the model of WMM focus on?

Answer 2

the processing of information NOT the ability to recall

Question 3

who proposed the WMM?

Answer 3

Baddley and Hitch

Question 4

what was the purpose of developing the WMM?

Answer 4

to better the understanding of the STM as it is not a singular store and has multiple layers

Question 5

how is the LTM linked to the STM?

Answer 5

by the episodic buffer

Question 6

what is are the 4 roles of the central executive?

Answer 6

• to decide where the attention need to be payed to
• to decide what components are needed for tasks
• coordinates retrieval from LTM
• the ability to switch information between tasks

Question 7

what is the capacity and encoding of the central executive?

Answer 7

limited and cannot encode as has no processing ability

Question 8

what are the 2 subdivides of the visuo-spatial sketchpad?

Answer 8

visual cache- stores visual info

inner scribe- records the arrangement of objects in a visual field

Question 9

how many objects can the VSS ‘contain’ in a visual field?

Answer 9

3-4

Question 10

what is the capacity and encoding for the VSS?

Answer 10

limited and visual

Question 11

what are the 2 subdivides of the phonological loop?

Answer 11

phonological store- processes speech perception and stores spoken words we hear for 1-2 seconds

articulatory control system- processes speech production, and rehearses and stores verbal information from the phonological store

Question 12

what is the capacity and encoding of the PL?

Answer 12

limited and acoustic

Question 13

what are the 2 ‘slave systems’ WMM?

Answer 13

PL and VSS

Question 14

what is the episodic buffer?

Answer 14

The episodic buffer acts as a ‘backup’ store which communicates with both long-term memory and the components of working memory (PL and VSS)
acting as a storage for the CE

Question 15

what is the capacity of the Episodic buffer?

Answer 15

limited only 4 chunks

Question 16

what is the encoding of the episodic buffer?

Answer 16

cannot encode as has no processing ability

Question 17

research + WMM?

Answer 17

Brooks
dual task
easier if tapping and verbal
harder when same component

Question 18

research - WMM?

Answer 18

lab

Question 19

practical applications + WMM?

Answer 19

PARK et al

schizophrenia trouble with WMM so used to diagnose by dual task

Question 20

theoretical - WMM?

Answer 20

oversimplified as role of CE unclear in the case of EVR couldn’t make good decisions but good reasoning skills after having a tumour removed from a part in his brain

Question 21

what research was conducted to prove the existence of the Central executive?

Answer 21

Bunge
FMRI allowed us to see what parts of the brain are more active, as task became harder activity in the pre-frontal cortex increased

most activity show in the dual task area as attention demands increase in the central executive

more demands=more activity

Question 22

what research was conducted to prove the existence of the VSS?

Answer 22

Brookes
Visualise letter and asked questions about it
can respond by tapping, pointing or speaking

quickest response– verbal or tapping as uses two different components

Question 23

what research was conducted to prove the existence of the PL?

Answer 23

Baddely
short vs long word list
recalled more short words as can be contained in the 1.5-2s cap shows that cap is based on time taken to say the word not the number of words

Question 24

what research was conducted to prove the existence of the episodic buffer?

Answer 24

Alkhakifa
patient with impaired ltm had a cap on 25 items in the short term memory
more than PL and VSS therefore can hold items
