26
Q

7+/-2 chunks of info

27
Q

small units that can be combined into larger meaningful units

28
Q

unit of the working memory space

29
Q

a collection of elements strongly associated with one another but WEAKLY associated with elements in OTHER chunks

30
Q

strength of info DECAYS OVER TIME unless it is periodically reactivated or pulsed

A

maintenance rehearsal

31
Q

decay and time are more disruptive on material than is more similar

A

confusability and similarity

32
Q

WM is resource limited and depends on limited supply of attentional reseources

A

attention and similarity

33
Q

similar concept with STM

A

Working Memory

34
Q

storage, processing and manipulation of info, active during complex cognition

A

working memory

35
Q

baddeley’s working memory model

A

phonetic loop
central executive
visuospatial sketch pad

36
Q

two components of phonological loop

A

phonological store
articulatory rehearsal process

37
Q

has a limited capacity and holds info for only a few sec

A

phonological store

38
Q

responsible for rehearsal that keep items in the phonological store from decaying

A

articulatory rehearsal process

39
Q

3 phenomena supporting phonological loop (PSE, WLE, AS)

A

phonological similarity
word length effect
articulatory suppression

40
Q

letters or words that sound similar are confusing

A

phonological similarity effect

41
Q

the memory is better for lists that have short words than long words

A

word length effect

42
Q

takes longer to rehearse long words and to produce them during recall

43
Q

speaking prevents one from rehearsing items to be remembered

A

articulatory suppression

44

it is where the major work of working memory occurs bcs the control central of the working memory system

A

central executive

48
Q

controls suppression of irrelevant info

central executive

50
Q

central executive as being (AC)

A

attention controller

51
