Findings
immediate recall worse with acoustically similar words , STM
is acoustic
Recall aster 20 mins worse with semantically similar words
LTM is semantic
→ the amount

information that
store
can be a memory
Capacity
Jacobs co 887 ) Testing elegit span
Procedure
researcher reads 4
digit and increases until the
participan
recall the order correctly Final
cannot .
number =
digit span
Findings
on participants could repeat back 9.3 numbers and 7.3
average ,
deters in the correct order immediately after they were presented .
Miller c v95 G) magic number 7+-2
Procedure
Miller observed everyday practise noted , that
things come in 7 's ,
eeg : notes
og musical scale days of the ,
week , deadly sins .
Findings
The span of STM us about 7 items ep.ws/ minus 2) but is increased
by chunking grouping sets
of digits / letters into meaningful units
-
STM -
between 5- 9 items
LTM -
unlimited
→
the
length of twine ingomation
can be held in one memory
Duration
.
Peterson and Peterson Cia 59) consonant syllables
accountable for
procedure hpp stm
24 students were given a consonant syllable Eeg :-/ C. G) to recall and a
3- digit number to count backwards the retention interval was
grom
.
varied :
3,6 , 9 , 12 , 15 or 18 Seconds
Findings
Aster 3 seconds -
average recall was about 80% .
After 18 seconds
it was about 3-1 .
.
STM duration without rehearsal is up to 18 seconds .
