working memory model

Question 1

who came up with this model

Answer 1

Baddeley and Hitch- 1974

Question 2

what is the central executive

Answer 2

supervisory component that has overall control of working memory

Question 3

what is the capacity of the central executive

Answer 3

limited but it can process information from any sensory system

Question 4

why is the central executive described as an attentional controller

Answer 4

because it can focus, switch and divide attentions

Question 5

what does the inner voice do in the phonological loop

Answer 5

it deals with auditory information

Question 6

what does the phonological store do

Answer 6

it holds words that are heard

Question 6

what does the articulatory loop do

Answer 6

it allows maintenance rehearsal

Question 7

what is the capacity of the phonological loop

Answer 7

2 seconds worth of what you can say

Question 8

what is the phonological similarity effect

Answer 8

where it is more difficult to remember similar sounding words and letters

Question 9

what is the word length effect

Answer 9

short monosyllabic words are more likely to be recalled than longer polysyllabic words

Question 10

what does the visuo-spatial sketchpad do

Answer 10

it stores visual information for when its required- inner eye

Question 11

what are the 2 sub-systems of the VSSP

Answer 11

visual cache and inner scribe

Question 12

what does the inner scribe do

Answer 12

records the arrangements of objects in the visual field

Question 13

what case study supports this model

Answer 13

KF

Question 14

what happened to KF

Answer 14

he got in a motorcycle accident and could process visual information but struggled with verbal information

Question 15

how does KF support this model

Answer 15

it supports the existence of 2 separate visual and verbal stores in STM as it seems like his phonological loop is affected but the VSSP isn’t

Question 16

what are the practical applications

Answer 16

it has been argued to help children with ADHD by breaking down information into manageable chunks with frequent repetition to help them remember things

Question 17

how do brain scan studies support this theory

Answer 17

Smith(1995) used brain scans to show how different areas of the brain are active when doing visual or verbal tasks which suggests that the VSSP and the phonological loop are separate systems

Question 18

name a criticism of this model

Answer 18

not all aspects of this model are fully understood which is a weakness as further research is needed

Question 19

what store supports the phonological similarity effect

Answer 19

phonological loop

Question 20

what are the stores in the phonological loop

Answer 20

what are the stores in the phonological loop

Question 21

what does the visual cache do

Answer 21

stores visual data

Question 22

what is the phonological loop

Answer 22

slave system that deals with the temporary storage of verbal information

Question 23

what does the articulatory rehearsal support

Answer 23

the word length effect

Question 24

what are the responsibilities of the central executive

Answer 24

it monitors information coming in from different sources

decides what to pay attention to

allocates tasks to slave systems

Question 25

name a limitation of this model

Answer 25

its inability to explain why we could store a limited number of word sequences in the phonological loop but could store far longer sentence sequences

Question 26

what did Baddeley and Hitch say about dual task performances

Answer 26

you can perform 2 different tasks at the same time as long as the tasks use different components of the working memory, if they do use the same parts of the same components processing will slow down

Question 27

what is the episodic buffer

Answer 27

it process all of the information from components and integrates it
