Q

in what 2 ways were results analysed?

A

by developmental periods (i.e five different age groups, 5 years, 6-8, 9-11 etc) and by course (i.e thirteen school years)

Q

healthy elderly had a significantly lower digit span than 5-6 year olds. true or false?

A

false, elderly had a higher digit span

17
Q

the healthy elderly did not significantly differ from other age groups. true or false?

A

true

18
Q

AD scored significantly higher than 5 year olds on the digit span test. true or false?

A

false, it was just higher

19
Q

fvFTD patients was significantly higher than 5 and 6 year olds digit span. true or false?

A

false, it was similar.

20
Q

how do these results differ to Gathercole and Alloway’s?

A

digit span continues to increase until age 17 in a Spanish population as opposed to 15

21
Q

digit span is higher in the Spanish population than in the Anglo-Saxon. true or false?

A

false, its lower.

22
Q

this difference is thought to be related to what?

A

word length effect (Badderley 1975)

23
Q

summarise the word length effect

A

this effect has been related to subvocal rehearsal and recall processes. in the first case, it is understood that the greater the word length, the longer it takes to perform the rehearsal and, therefore, the easier it is to lose informationduring the rehearsal of a succession of long words.

24
Q

results for this study differ from Anglo Saxon data at what age? why is this thought to be?

A

from age 7 and 8 onward.

due to the rise of subvocal rehearsal at these ages

25
Q

other than word length effect what other stategies may impact on working memory span?

A

recoding or chunking, intercultural differences

26
Q

there was a clear effect of age on working memory digit span in this study. true or false

A

true

27
Q

there was a significant difference in digit span between healthy elderly, AD and fvFTD group. true or false

A

false, there was no significant difference

28
Q

it can be concluded that the phonological loop is affected by age but not by dementias. true or false?

A

true
