Q

what is Stenberg’s slope

Q

what has STM from MSM been replaced by

A

WMM

26
Q

what is the duration of the STM

A

If not rehearsed, info is lost within ± 15-20 sec

27
Q

define rehearsal

A

the process of repetitively verbalizing or thinking about the information

28
Q

what is retroactive forgetting

A

new learning interferes with old memory

29
Q

what is proactive forgetting

A

old learning interferes with new memory

30
Q

what makes interference more likely

A
  • stimuli similar
  • learning of large volumes of info
  • learning material close together in time
  • learning in the same context
31
Q

function of the LTM

A

Organises and stores information

32
Q

capacity of LTM

A

unlimited

33
Q

duration of LTM

A

permanent

34
Q

what does WMM say STM is

A

A “mental workspace” which is the basis for thought

35
Q

what is the central executive

A

-modality-free
-central pool of mental resources
-control & decision processes
(cf. attention)
-no real storage

36
Q

what is the phonological loop

A

-”inner ear & voice”
-verbal rehearsal
-info = speech-based

37
Q

what is the episodic buffer

A

-holds and integrates diverse information

38
Q

what is the visuo-spatial sketchpad

A

-”inner eye”
-spatial and/or visual coding

39
Q

what is the evidence for the phonological loop

A

Phonological similarity effect
Word length effect
Unattended speech effect
Articulatory suppression effect

40
Q

what is the phonological similarity effect

A

errors more likely to be phonologically similar to correct item, more likely to misremember if items sound similar

41
Q

what is the word length effect

A

The memory span for short words is greater than for long words

42
Q

what is the unattended speech effect

A

Performance impaired if other verbal material needs to be ignored

43
Q

what is articulatory suppression

A

when we prevent rehearsal by articulation of other information

44
Q

what is the visuo-spatial sketchpad

A

A system for setting up and manipulating images and spatial movement

45
Q

2 components of the visuospatial sketchpad are:

A

visual cache: visual information about shape & colour (the “what”)
inner scribe: spatial & movement information (the “where”)

46
Q

function of the visuospatial sketchpad

A

construction, maintenance, manipulation of mental images

47
Q

what is the central executive

A

an attentional system which can maintain task goals and goal-related information and use this to direct / bias your processing

48
Q

does CE have storage

A

no

49
Q

roles of the CE

A

Directing attention to task, updating of task at hand
Switching/shifting between strategies
Selective attention & inhibition

50
Q

location of CE

A

prefrontal cortex

51
Q

what is dysexecutive syndrome

A

Disruption of CE due to frontal lobe damage

52
Q

define catatonia

A

remain motionless and speechless for hours due to inability to initiate schemas

53
Q

perseverance is

A

inability to sort by value

54
Q

utilisation behaviour is

A

automatic responding to cues in environment- failure to focus attention

55
Q

what do people with Alzheimer’s struggle to do

A

distribute attention between two tasks

56
Q

what can the episodic buffer do

A

integrate information into single complex structure (episode)

57
Q

coding of episodic buffer

A

multidimensional

58
Q

capacity of episodic buffer

A

4 pieces/chunks of info in multidimensional code

59
Q

episodic buffer assists in binding, which is…

A

integrating information about location, colour, size, etc. of objects and scenes
