(9 cards)
what is interefence
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
what are the 2 types of interference
proactive intereference
retroactive interference
what is proactive interference
- older memory interferes with a new one ,
what is retroactive interference
- newer memory interfers with an older one
research
- 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
research findings
- 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
strength , everyday situations
p- evidence , interference = effects everyday situations
e- baddeley and hitch 1997, rugby players , recall names of teams they’d played against during rugby season , players played over 1 season , but number of games played were diff , bc of injury
e- players who played most games ( most interference for memory) , had worst recall
l- shows interference can operate in some real word situations , increases validity of theory
limitation , artificial
p- research uses artificial tasks
e- list of words =. lack meaning , doesn’t represent real life memory
e- reduces ecological validity of findings , results dont generalise to everyday memory
strength , languages
p- explains why its more harder to learn a lang e.g French if another lang has already been learnt , e.g Spanish
e- gives theory good external validity
