sebastian and hernadez gill Flashcards
what was the aim of the study?
to investigate the development of the phonological loop in children between 5 and 17 by evaluating verbal digit span
in particular to see whether digit span increases with age
compare results with those of elderly and AD and FvDTD patients of previous studies
who were the participants?
570 volunteers
where were participants from?
preschool, primary and secondary schools in madrid
how many groups were participants split into?
17
what wa the method of the study?
asked to listen to a sequence of 3 digits and recall them in the same order
an extra digit was added each time to increase the length
maximum digit span was reached when participants could recall 2 or 3 series without any errors
took part individually
rate of one per second
what was the start number of digits?
3
when was maximum digit span reached?
when 2 or 3 series could be recalled without any errors
max digits recalled without error
what was the digit span of the age groups?
5 - 3.76 6-8 - 4.34 9-11 - 5.13 12-14 - 5.46 15-17 - 5.83
how as data analysed?
by developmental years
what was the digit span of 5 years?
3.76
what wa step digit span of 6-8?
4.34
what was digit span of 9-11?
5.13
what was digit span of 12-14?
5.46
what was digit span of 15-17?
5.83
digit span of AD patients?
4.20
didgit span of FvFTD?
4.22
digit span of elderly
4.44
what was found about digit span?
that digit span increases with age
5=3.76 and 15-17=5.83
what was found about elderly and patients?
no significant differences
due to similarities between children and elderly what can be concluded?
that the phonological loop is more affected by age than dementia
what can differences between development of digit span between spanish and english be down to?
word length effect
spanish poly syllabic numbers
what did baddeley say about word length?
the longer a word is the longer it takes to rehearse it meaning that it is more likely to be lost
when was it done
2012
