forgetting = interference

Question 1

what is interefence

Answer 1

forgetting as one memory blocks another, causing one or both memories to be forgetten or distorted

• explanation for forgetting ltm,
• happens because memories mix up and overlap with each other
• even tho information is stored, can’t access it because other memories are in the way

Question 2

what are the 2 types of interference

Answer 2

proactive intereference
retroactive interference

Question 3

what is proactive interference

Answer 3

• older memory interferes with a new one ,

Question 4

what is retroactive interference

Answer 4

• newer memory interfers with an older one

Question 5

research

Answer 5

• pi and Ri is worse when memories are similar

-mcgeoch and McDonald-
tested ri
- had ppt rmb list of 10 word till the knew it perfectly , then they learnt a new list , there were 6 diff conditions with different types of lists :
g1- synonyms
g2- antonyms- opposoite meaning
g3- words unrelated to the original ones
g4- consonant syllables
g5- three digit numbers,
g6- no new list -rested control conditions

Question 6

research findings

Answer 6

• asked to recall og list, remembered it worse when the new list had synonyms ,
• shows that interference happens more when new and old memories are similar

Question 7

strength , everyday situation

Answer 7

p- evidence of interference effecting everyday situations

e- baddeley and hitch , asked ruby players to name the teams they had played against that season, all players had played in the same interval , but some played more matches than others due to some being off the pitch bc of injuies

e- found that those whom played the most matches had the worst recall of the teams names

l- shows interference can happen in real world situations = increases validity of theory

Question 8

limitation , cues

Answer 8

p- forgetting = not permanent , can rmb things with cus

e - tulving and psokta , gave ppt words, organised into cateogries , didnt tell them cateorgies , at first , ppt remembered 70% of words, as they learnt more lists, recall got worse, which is pi

e - but did the words rlly disappear from memory or were they still there? at the end of the experiment , they were given a hint by telling them the cateorgy of the word, =. remembered 70% again

l- interference. = doesn’t erase memorises, but makes it harder to access them , doesn’t fit with what interference theory suggests, ( memory gone completely)

Question 9

strength

Answer 9

p- evidence for retrograde. facilitation ( reducing interference = improves memory)

e- coenen et al, ppts learn list of words + recall later, usually new experiences = inference , making recall harder, but they tested this using diazepam , a drug ,

e2- learnt words AFTER taking diazepam = recall was worse than control group who didnt take drug, if learnt words BEFORE taking diazepam = recall was better than control group , meaning drug helped memory

e- wixted, = said that diazepam , blocks new memories from forming , so new memories can’t interfere with older ones, protects memories from ri ,

l - supports interefence , shows that forgetting = due to interefernce , not memory decay , interference reduced= forgetting reduced
