Explanations Of Forgetting - Inteference Flashcards
Intro
Idea that something els e gets in the way and interrupts memory
Interference- we forget when a similar memory interrupts anther one - harder to recall but doesn’t mean memory is decayed
Retroactive interference
Muller - current learning interferes with past learning
Gave a list of nonsense syllables to learn for 6mins, after retention retrieval, participants asked to recall list
Performed less good if participants had been giving intervening task (look at paintings) between learning and recall
Later task had interfered with with what had previously been learnt
Proactive interference
Underwood - past learning interferes with current attempts of learning
Participants who had to learn 10 or more lists and after 24h could only remember 20%, those who learnt 1 could remember 70%
Similarities of test materials
McDonald - looked at retroactive interference
Share similar worlds (synonyms) then after 10mins learnt not similar words
If list B was synonyms of list A, recall was 12%, if list B was nonsense syllables, recall was 26%
Shows interference is stronger when items are similar because of interference not decay of memory
Real world study
Braddley and hitch - investigated interference happens in everyday life
Playing 20 matches but ant remember all as memory is similar therefore get confused and blurred
If played 20 different sports - easier to remember each one as memories are different
A03 - limitation - research is artificial
P - mos research is lab-based and often use artificial list of words
E - findings a not relate to everyday life and use of memory doesn’t involve lists. Also people may lack motivation to remember lists so interference will seem stronger
E - research has low ecological validity
Ao3 - limitation interference only explains some situations of forgetting
P - interference doesn’t occur that often
E - two memories need to be quite similar - for this reason interference is considered to be unimportant explanation of everyday forgetting. Not all similar memories are forgetting
E - how much forgetting can be attributed to interference remains unclear
Ao3 - limitation - accessibility vs availability
P - researchers often question whether interference effects actually cause memory to disappear of whether it’s just temporary
E - if memory was tested again after 24h, recognition (accessibility) showed spontaneous recovery, whereas recall (availability) remain the same
E - suggests the interference occurs because memories are temporarily not accessible rather then having actually been lost (unavailable)
