explanations for forgetting: interference
- interference theory
- basics
- when 2 pieces of info conflict with each other
- proposed by an explanation of forgetting
things in the LTM
- forgetting is because we cannot access it not because
it isn't there
- types of interference
- proactive interference
- older memories interfere with newer ones
- pro = forward - old to new
- retroactive interference
- newer memories interferes with
older ones
- retro = backwards - new to old
- effects of similarity
- McGeoch and McDonald - retroactive interference
- procedure
- all had to learn one list until 100% accurate
- learn another list
- group 1 = synonyms - same meanings
- group 2 = antonyms - opposite meanings
- group 3 = unrelated words
- group 4 = nonsense words
- group 5 = three digit numbers
- group 6 = no new words
- findings
- most similar words = greater interference
- evaluation
- evidence form lab studies
- 1000s of experiments like this have
been done and all have the same
results
- increases validity and can be generalised
- artificial materials
- the list used to remember has all been words
or letters of some sort
- we wouldn't have to do this in everyday life
- not a way of explaining forgetting in everyday life
- real life studies
- Baddeley and Hitch
- rugby players to say who they had played that season
- those who had missed more games got more of them right
- shows that it's not the period of time since they
played it but how many games they have played
after it
- evaluation +
- time between learning
- lab experiments designed so that interference is at its max
- but not too long so it is just forgetting
- memory tests done within on hour
- interference effects may be overcome using cues
- Tulving
- five lists of 24 words in six different categories
- recall of the first list was 70% then decreased due to interference with the other lists
- when given cues about the categories it increased again to 70%
