wmm

Question 1

what is the use of the wmm

Answer 1

limited capacity store for retaining information for a brief period while performing metal operations using that information

Question 2

what type of system is the wmm

Answer 2

a multi-component system

Question 3

what is 3 importances of the working memory

Answer 3

reasoning
learning
comprehension

Question 4

what is a key assumption about the working memory

Answer 4

that complex reasoning and learning tastks require a mental workspace to hold and manipulate information

Question 5

what does the central executive responsible for

Answer 5

monitoring and coordinating the slave systems

Question 6

what does CE decide

Answer 6

which information goes to which part of the WM

Question 7

what other processes does the CE carry out

Answer 7

cognitive tasks- mental arithmaric and problem solving

Question 8

what is the capacity like

Answer 8

limited capacity and does not store any information

Question 9

what special quality does the CE have

Answer 9

selective attention - can only process one piece of inforamation at a time

Question 10

evidence CE

Answer 10

Alzheimer’s disease

Question 11

why is this useful

Answer 11

disease have shown decreased central executive function as the disease progresses

Question 12

whos study tested this theory

Answer 12

baddeley’s

Question 13

what happened in the study

Answer 13

conducted a series of dual experiments on young, elderly and Alzheimer’s patients using verbal and visual tasks together or separately

Question 14

results

Answer 14

performance of the Alzheimer’s groups did not suffer significantly when the groups performing visual or verbal tasks separately but it did show significant impairment when trying to do them together

Question 15

what does this present linked to the CE

Answer 15

the central executive is responsible for coordination of the sub systems so the impairment when trying to do two tasks of different sub systems demonstrates significant problems with the executive functioning

Question 16

problem with researching the central executive

Answer 16

it cant be directly measured itself has to be inferred from verbal and visual tasks

Question 17

what is often the conclusion when there could be a problem with the CE

Answer 17

that the phonological loop is impaired instead

Question 18

whats the role of the visuospatial sketchpad

Answer 18

stores and processes information in a visual or spatial form used for navigation

Question 19

what records arrangments of objects in a visual field

Answer 19

inner scribe

Question 20

capacity

Answer 20

3/4 objects

Question 21

who criticises the VSS

Answer 21

lieberman

Question 22

what does he believe is incorrect about the VSS

Answer 22

visual and spatial information is processes seperately should be in different component

Question 23

whats evidence for this

Answer 23

blind people have good spatial awareness even with having never had any visual information

Question 24

another supporting

Answer 24

PET scans have provided evidence as when carrying out visual WM tasks more activity in left and spatial tasks more activity in the right half of the brain.

Question 25

what does the phonological loop do

Answer 25

deals with spoken and written material

Question 26

what are the 2 stores the loop is seperated into

Answer 26

phonological store and articulatory process

Question 27

what does the phonological store do

Answer 27

holds information in a speech based form

Question 28

what does the articulory process do

Answer 28

allows us to repeat verbal information in a loop

Question 29

whats the duration of the phonological store

Answer 29

2 seconds

Question 30

evidence study

Answer 30

sebastian and hernandez gil

Question 31

what happened in this study

Answer 31

studied the development of the phonological loop in children and compared results to anglo-saxon which presents the idea that words are repeated in our minds for a short period of time via the phonological loop.

Question 32

how does this show the presence of the phonological loop

Answer 32

Results were slightly better from Anglo-Saxon participants due to the word length effect. This is because Spanish words are longer than English words therefore when Spanish participants were recalling the numbers it would take longer for them to say the word out loud meaning less time the words could be held in the phonological loop compared to English paricipants.

Question 33

another evidence study by…

Answer 33

Baddeley, Thomson and butchanan

Question 34

what happened in this study

Answer 34

Participants had to recall 5 words from a list of longer and shorter words, the recall who is better from the list of shorter words compared to the list of longer words.

Question 35

what does this suggest

Answer 35

This suggests that the duration of the loop is up to two seconds.

Question 36

what is the eposodic buffer

Answer 36

The episodic buffer acts as a “backup” store which communicates with both long-term memory and the components of working memory.

Question 37

what does it do

Answer 37

Holds long term memory in the short term memory while we use the information we need.

Question 38

capacity of eposodic buffer

Answer 38

limited of 4 chunks

Question 39

what types of information does is process

Answer 39

Interrogates the acoustic, visual and spatial information processed but over sub systems in the long term memory
