Question 18

SM duration experiment

Answer 18

Sperling 1960

Question 19

Sperling 1960

procedure

Answer 19

shown a grid for 0.05 seconds and expected to recall

Question 20

sperling 1960

results

Answer 20

whole grid recall= 4-5 letters

one row= 3 items

Question 21

STM duration experiment

Answer 21

Peterson and Peterson 1959

Question 22

Peterson and Peterson 1959

method

Answer 22

trigram recollection
3-18 seconds after showing
count backwards= inference task

Question 23

peterson and peterson 1959

results and conclusion

Answer 23

3 seconds = 80% recalled

18 seconds = 10% recalled

less than 18 seconds

peterson and peterson 1959

Question 25

1975 LTM

Answer 25

Bahrick | graduation class

Question 26

Peterson and Peterson 1959

Answer 26

Trigrams

Question 27

Bahrick 1975

Answer 27

graduation class

Question 28

Bahrick free recall test

Answer 28

list names of ex-classmates 15yrs=60% accurate 30yrs=30% accurate

Question 29

Bahrick photo-recognition test

Answer 29

shown photos, recall names 15yrs= 90% 48yrs= 40%

Question 30

Bahrick name-recognition test

Answer 30

match names to photos 15yrs=90% 48%=80%

Question 31

Bahrick conclusions

Answer 31

recognition is better than recall | huge store of memory but hard to access it all

Question 32

experiments for capacity of STM

Answer 32

Jacobs 1887- 5-9 items | Miller 1956- magic number + chunking

Question 33

Jacobs 1887

Answer 33

had to repeat back in order a string of letters/digits 9 digits 7 letters capacity increased during childhood 5-9 items

Question 34

Miller 1956

Answer 34

7 +/- 2 | suggested chunking to remember more

Question 35

chunking

Answer 35

combining digits/letters into meaningful groups (chunks)

Question 36

encoding STM LTM

Answer 36

Baddely 1966

Question 37

Baddely 1966

Answer 37

acoustically/semantically similar/dissimilar | difficulty recording STM acoustically similar and LTM semantically similar
