cambridge uni

Question 4

what department

Question 5

what type of sample was it

Answer 5

self selected

Question 6

what was group A

Answer 6

acoustically similar words stm

Question 7

group b

Answer 7

control group stm acoustically dissimilar

Question 8

group c

Answer 8

LTM semantically similar

Question 9

group d

Answer 9

LTM control semantically dissimilar

Question 10

control variables

Answer 10

hearing tests prior test hearing ability and words were also displayed visually on a projector to control extraneous variables

Question 11

what year was this study

Answer 11

1966

Question 12

IV

Answer 12

type of words

Question 13

DV

Answer 13

number of words subjects could recall in the correct order

Question 14

how long was the list of 10 words presented for

Answer 14

3 seconds

Question 15

what was the interference task

Answer 15

digit task 8 seconds to write down digits

Question 16

what did it prevent

Answer 16

prevented people using there stm and repeating acoustic sim words in head

Question 17

what happened next

Answer 17

wrote down original list of 10 words in correct order

Question 18

how many times was this repeated

Answer 18

4

Question 19

what happened at the end

Answer 19

15 min supprise test

Question 20

what did this test

Answer 20

conclude that semantically similar group would struggle to recall words as LTM gets confused by semantically similar words

Question 21

what were the results for semantics

Answer 21

semantically dissimilar did best semantically similar did worst

Question 22

why

Answer 22

the struggle of encoding semantically similar into LTM shows words are encoded semantically similar into LTM

Question 22

results for acoustically

Answer 22

quite similar but acoustically similar did worse at the beginning because they attempt to use stm - struggles - worse results but by 4th trial not using stm anymore - no struggle.

Question 23

what design is this study

Answer 23

independant measures

Question 24

conclusion of ltm

Answer 24

Long term memory gets confused when it has to retrieve the order of words which are semantically similar as it gets distracted by semantic similaritiesWhen words have similar meanings they actively relate to neutral networks in our brain that already exist creating strong connexions although it can retrieve acoustically similar words as long time memory pays no attention to the sound of words and therefore does not get confused

Question 25

why is there a slow start to acoustically similar

Answer 25

As we know short term memory encodes acoustically similar and the interference task doesn't 100 percent block the short term memory straight away as some words linger in the rehearsal loop although In test 4 short term memory is blocked.

Question 25

what does confusion show

Answer 25

If participants get confused or struggle it suggests that the similarity relates to how memories work for example if they get confused semantically similar when testing long term memory it means that people encode semantically similar.

Question 26

how many ppts in each group

Answer 26

15-20

Question 27

how many people was the whole sample

Answer 27

72
