memory ; wmm

1 of 69
what is it an explanation of?
how the stm is organised and fucktions
2 of 69
what part of the mind is it concerned with?
part that's active when we're temporarily storing and manipulating information e.g working on maths / chess
3 of 69
how many components?
4 of 69
central executive / phonological loop / visuo-spatial sketchpad / episodic buffer
5 of 69
each model is different in which two ways?
coding and capacitu
6 of 69
central executive
7 of 69
what is it essentially?
attentional proccess
8 of 69
that monitors?
incoming data
9 of 69
and makes?
10 of 69
and allocates?
tasks to slave systems
11 of 69
does it have a very limited processing capacity?
12 of 69
phonological loop
13 of 69
is it a slave system?
14 of 69
how many are there
15 of 69
what type of information does it deal with?
16 of 69
and preserves what?
order in which info arives
17 of 69
what two things is it subdivided into?
phonological store / articulatory process
18 of 69
what does the phonological store do?
store words you hear
19 of 69
what does articulatory process allow for?
maintenance rehearsal
20 of 69
what is the capacity of this loop believed to be?
two seconds
21 of 69
visuo-spatial sketchpad
22 of 69
what type of info does it store?
visual and/or spatial (shocker, i know)
23 of 69
what did baddeley suggest its capacity is limited to?
3/4 objects
24 of 69
logie subdivided it into?
visual cache / inner scribe
25 of 69
what does visual cache store?
visual data (yet another shocker)
26 of 69
iwhat does inner scribe record?
arrangement of objects in visual field
27 of 69
episodic buffer
28 of 69
when was this added by baddeley
29 of 69
what is it?
temporary store for information
30 of 69
what does it integrate?
visual / spatial / verbal info from other stores
31 of 69
to maintain?
sense of time sequencing
32 of 69
what can it be seen the storage component of?
central executive
33 of 69
and has capacity of?
about 4 chunks
34 of 69
what does this link working memory to?
ltm + wider cog processes e.g perception
35 of 69
36 of 69
:) clinical evidenec
37 of 69
which case study does support come from?
38 of 69
after this damage what type of information did he have poor stm ability for?
39 of 69
but could process which type?
visual information
40 of 69
this suggests that just which area had been damaged?
phonological loop
41 of 69
what two separate stores does this support existance of?
separate and visual
42 of 69
but why may brain-damage evidence be unreliable?
because these are unique and traumatic cases
43 of 69
:) dual-task performance
44 of 69
what do studies into this support separate existance of?
visuo-spatial sjketchpad
45 of 69
what did baddeley show pps had difficulty doing?
two visual tasks
46 of 69
which were?
tracking light and describing letter f
47 of 69
and what did they find easier?
doing verbal and visual task at same time
48 of 69
why could this difference suggested to have happened?
bc both visual use the same slave system
49 of 69
which means there must be?
a separate visual slave system
50 of 69
:( lack of central executive clarity
51 of 69
what have cognitive psychologists said about this?
unsatisfactory and non explanatory
52 of 69
central executive (as admitted by baddeley) needs to be more specified than just?
53 of 69
e.g some psychologists believe it could consist of?
separate components
54 of 69
which means what for the wmm?
hasn't been fully explained
55 of 69
56 of 69
:) studies of the word
57 of 69
what did baddeley find about remembering long and short words
more difficult to remember long than short words
58 of 69
what did he call this?
the word length effect
59 of 69
why does this happen?
bc finite space for rehearsal in ariculatory process
60 of 69
how long?
2seconds worth
61 of 69
this effect disappears though if person given?
articulatory suppression task
62 of 69
which is?
repetitive task that ties up articulatory process
63 of 69
e.g doing a task while saying lalala means?
atriculator process kept busy
64 of 69
:) brain scan studies
65 of 69
what did braver do while brain scanning pps?
gave tasks which involved central executive
66 of 69
where did rsrchers find greater activity?
left prefrontal cortex
67 of 69
what was observed as task got harder?
activity in area increased
68 of 69
how does this apply to wmm?
as demands on central exec increase, it has to work harder to fulfil function
