4
Q

define proactive interference

A

previously learnt information distorts the new information you are trying to store

e.g: calling a new student by an old students name

Q

define retroactive intereference

A

new memories distort old ones

e.g: cannot recall the name of old students because you now can only recall the new names

Q

what was the 6 groups of lists in McGeoch and McDonald’s study

A

group 1: synonyms
group 2: antonyms
group 3: words unrelated to the original
group 4: consonant syllables
group 5: three digit numbers
group 6: no new list (control condition)

Q

what were the findings of McGeoch and McDonald’s study

A

the most similar material produced the worst recall and the best recall was when they were given no list and were allowed to relax (the control group)

Q

explain why the findings of McGeoch and McDonald’s study

A

the more similar the material is the more likely you are to forget due to interference theory as retroactive interference is occurring (new list is causing you to forget the old original list that you need to recall)

Q

what was the procedure in McGeoch and McDonald’s study

A

participants had to learn a list of 10 words until they could remember them with 100% accuracy an d then were given a list of new words that fell into 6 different categories and then were asked to recall the original list of words

Q

why may forgetting occur

A

forgetting may occur due to insufficient cues at the time of recall

Q

what is the encoding specificity principle (ESP)

A

for a cue to be helpful it has to be present at encoding and at retrieval

if cues are different or absent this is when forgetting occurs

16
Q

define state dependent forgetting

A

recall depends on internal cues

(e.g: feeling upset, being drunk)

17
Q

define context dependent forgetting

A

recall depends on external cues
( e.g: weather, place, sounds, smells)

18
Q

who did research into context dependent forgetting

A

godden and baddeley
1975

19
Q

what type of participants did godden and baddeley use in their study on context dependent forgetting and why

A

deep sea divers as they wanted to see how learning on land affected work underwater

20
Q

what was the procedure of godden and baddeley’s study

A

diver learnt a list of words on land or underwater and then had to recall that list on land or underwater

21
Q

what were the 4 conditions in godden and baddeley’s study

A

encoding on land retrieval on land

encoding on land retrieval underwater

encoding underwater retrieval on land

encoding underwater retrieval underwater

22
Q

in which conditions did participants perform best in godden and baddeleys study

A

land and land was the best followed by underwater and underwater

23
Q

what were the findings in % if the conditions idn’t match

A

accurate recall was 40% lower

24
Q

explain the findings of godden and baddeley’s study

A

when cues during learning are different to cues during recall this led to retrieval failure

25
Q

who did research into state dependent forgetting

A

carter and cassady
1998

26
Q

in carter and cassady’s study what did they give to participants to make them slightly drowsy

A

antihistamine drugs

27
Q

what was the procedure of carter and cassasdy’s study

A

participants had to learn list of words and prose passages then recall them in one of 2 states (drugs, no drugs)

28
Q

what were the 4 states for encoding and retrieval

A

encoding drugs retrieval drugs

encoding drugs retrieval no drugs

encoding no drugs retrieval drugs

encoding no drugs retrieval no drugs

29
Q

what happened when the state during learning was different to the state during recall

A

then recall was significantly worse

30
Q

why when cues aren’t available is there more forgetting

A

this is due to retrieval failure
