Q

study for duration of STM

A

Peterson and Peterson 1959
24 undergraduates were shown a consonant trigram and 3 digit number and asked to count back in 3s from the number then recall the letters after a period of 3, 6, 9, 12, 15 and 18 seconds.
90% correct after 3 seconds
20% correct after 9 seconds
just 2% could recall the letters after 18 seconds, showing that STM duration is less than 18 seconds when verbal rehearsal is prevented

test of memory
72 British participants in a lab
list of words to remember and recall
1. acoustically similar
2. acoustically dissimilar

Q

Baddeley memory
findings

A

when asked to recall straight away they did worse with acoustically similar words as they get muddled in your head- shows that STM is coded acoustically

when asked to recall after 20 minutes, they did worse on semantically similar words showing LTM is coded semantically
