(A01) According to Miller,
most ppl have a digit
span of 7 + or -2
PROBLEM (AO2): Bower &
Winzenz found it is difficult to
exclude influence of LTM
(A02) Miller suggested our immediate
memory span (capacity) is
determined by the number of
chunks of info we can hold rather
than individual letters or numbers
BADDLEY ET AL (AO1)
A: Baddley wanted to find out if capacity in STM was determined by
pronouciation time rather than the number of items to be recalled (Did
a study testing wether people could remember short words more than
long words)
P: Showed lists containing
monosyllabic words & lists showing
polysyllabic words
FINDINGS:
Pp's coulf recall
significantly more
short words than long
words
Pp's able to recall the
nu. of words they
could articulate in 2
secs
Strong positive correlation
between reading speed &
memory span
NAVEH-BENJAMIN & AYRES (A02)
Tested the digit span technique
with speakers of different
languages
Found Arabic speakers had
a lower digit span than
English speakers
Concluded only
explanation for this is
pronouciation time
Findings support Baddley; Pronounciation time is more
important than the number of items to be recalled
