what is the role of the central executive (CE)?
It directs attention to particualr tasks, determining how resources are allocated to those tasks using data from either the senses or the LTM
3 of 26
What is the capacity of the CE?
Very limmited, it relies on its slave stores to hold data
4 of 26
what is the purpose of the phonological loop?
to preserve and process autitory information
5 of 26
What is the phonological loop broken down into?
In 1986 Baddeley split it into the phonological store and the articulatory process
6 of 26
What is the phonological store?
It holds the words you hear like and inner ear
7 of 26
What is the articulatory process?
used for words that are heard but not seen and are silently looped like an inner voice (maitnenece rehaershal)
8 of 26
when is the Visuo-spatial sketchpad (VSS) used?
It helps us plan spatial tasks, temporarly storing spatial or visual information
9 of 26
Who broke it down and into what?
Logie (1995) broke it down into the visual cache and the inner scribe
10 of 26
what is the inner scribe?
stores the arrangement of objects in a visual field
11 of 26
What is the visual cache?
stores information about visual objects such as form and color
12 of 26
When was the episodic buffer (EB) added?
the episodic buffer was added in 2000 by Baddeley
13 of 26
What is the EB's function?
to store nonspecific information for joint tasks as the CE has no space for that. it integrates information from different subsections

E1 (strength): How does the WMM solve duel task performance?
Baddeley and Hitch (1976) conducted a study supporting the existance of the central executive using two tasks completed at the same time
15 of 26
E1 (strength): What did task 1 do to preocupy the CE?
It occupied the CE by presenting a statement: "A comes before B" before showing BA and asking whether its true or false
16 of 26
E1 (strength): what were the two conditions to task 2?
It either involved the articulatory loop = saying "the" repeatedly OR it invloved the AL and the CE saying random digits
17 of 26
E1: what were the findings?
Task 1 was slower when task 2 involved both the AL and the CE
18 of 26
E2: which case studies support the WMM?
KF could remember visual stimuli but not a aural stimulus suggesting that his Phonological loop was damaged
19 of 26
E2: how does SC support WMM?
while his learning was good he could not remember word pairs when said out loud suggesting that his phonological loop was damaged
20 of 26
E2: how does LH support WMM?
He was better at spatial tasks than those involving visual imagery: suggesting his visual cache has damaged
21 of 26
E3: who criticized the CE for being to vague?
Eslinger and Damasio (1985) - They studied EVR who had good reasoning ability but poor dicision making skills = The CE is too vague
22 of 26
E3: Why did Eslinger and Damasio (1985) suggest that the CE was too vuage?
because EVR's reasoning skills suggested that his CE was intact but his poor decision making skills suggested that it wasn't intact. The contradiction suggests the CE is an underdeveloped concept
23 of 26
E4: Why is there an issue with basing supporting reaserch on brain damage patients?
Brain damage by it's nature is traumatic which suggests that there may be a confoundig variable that underlies behavior and may invalidate the supporting evidence
24 of 26
E5: How did Baddley support the phonological loop and the articulatory process?
He demponstrated that it was hareder to learn a lis of longer words like, "extraneous" are harder to learn than a list of short words like hat
25 of 26
E5: why did Baddley reach this conclusion?
Because the auditory process of STM is limited to 2 seconds of heard information. any more and displacment occurs
