Name a study that looks at the duration of the SR
Sperlings flashing rows
how many rows did PPS remember in Sperlings first study.
3or4/12
What conclusion did Sperling draw from his first study into the capacity of the STM
It is very limited
What did Sperling do in his second study ?
Looked at the duration of the SR by playing a tone then asking PPS the letters on that row
what was thew findings and conclusion in sperlings second study?
each PP remembered 3or4 letter on each each row showing that PPS remembered 9/12 letters. this shows duration is short because PPS could not report this in the first study.
What did Miller find in his digit span study ?
that PPS were able to remember 7+/-2 items
What were PPS asked to do in Millers digit span study?
read rows are numbers and recall them back
what was the conclusion in Millers digit span study ?
the STM has a duration of 7+/-2
Name a study into the capacity of the SR
Sperlings flashing rows
what were PPS asked to do in Petersons and Petersons trigram study ?
they saw a trigram and were then asked to count backwards . the time to count back increased. PPS were then asked to recall the trigram
what were the findings in the Peteresons and perterson trigram study
at 3 seconds recall was good but at 18 it was very poor ( 10%)
what were the 2 conditions in the high school photos study
one condition they had names to match to faces the secnd they had no names
conclution in Bahicks study
the Duration of the LTM is long especially with promts
what was the procedure for conards study ?
ask PPS to recall acoustically similar letters in order then do the same with non acoustically letters.
what were the 4 conditions in Baddlys study
acoustic sim
acoustic dissim
semantic sim
semantic dissim
how long was the wait until PPS were called back in the similar words study
20 mins
what results were found in the similar worlds study
no difference in acoustic however a 30% change from sim to dissim
